Performance After A Gap And Go Day

One test I ran tonight looked at performance following a day when the market gapped up at least 1% and then tacked on another 1% from open to close. The first table below shows the results for the QQQQ:

Results here are quite negative.

Next I looked at the SPY:

Here results were more mixed with the max loss accounting for all of the losses in most time periods.

I also looked to see how often the gap up got filled when the market was trading below its 200 day moving average. For the Nasdaq 55% of the time the gap was filled within 5 days and 74% of the time within 10 days. For the S&P the results again were not nearly as negative. Only 41% were filled within 5 days and 55% within 10 days.

A partial retracement of today’s move at some point seems likely. It may or may not be a few days before that begins, though.

Mid-Sized Gaps Up

After the close today, Intel had a good report. Everyone seems happy (unless you’re short Intel.) The Nasdaq futures are juiced and the S&P’s are even up quite a bit as I write this. We stand a good chance of seeing a gap up tomorrow morning. There are some economic reports to deal with before the opening bell so things can clearly change, but it seems like a good idea to expect we may gap in the morning and to plan for it.

Previously I’ve looked at large gaps up as well as large gaps down, and how the market reacted to them in both uptrends and downtrends. Today I will look at mid-sized gaps up.

As a reminder I previously defined a large gap as one over 0.75% for the SPY. The mid-sized gaps I’m looking at tonight are gaps between 0.25% and 0.75%. Once again I will break the results out between mid-sized gaps up in uptrends and mid-sized gaps up in downtrends. You’ll find the results to be quite different from both each other and the large gap studies.

For uptrend vs. downtrend I kept it simple and used the same definition as last time. If the market closes above its 200-day simple moving average, it’s in an uptrend. If the market closes below it, then it’s in a downtrend.

I looked at 3626 trading days going back to 11/17/93. Of those there were 613 mid-sized gaps up in uptrends and 223 mid-sized gaps up in downtrends.

Buying at the open and selling at the close when the market was in an uptrend would have been profitable about 50% of the time. In total the market would have gained 3% over the 613 trades. On a per-trade basis that’s basically break even. Of those gaps up 356 (58%) filled at some point during the day. (A fill in this case is defined as a move back down to the previous day’s close.)

Buying at the open and selling at the close when the market was in a downtrend would have been profitable 54% of the time. In total, though this strategy would have LOST you almost 66% over 223 trades. Per trade that’s close to a 0.3% loss on average from open to close. Of those mid-sized gaps up, 165 (73%) filled at some point during the day. Even with a slightly higher winning percentage these stats are significantly worse than those above dealing with uptrends.

We previously found that large gaps up typically lead to more upside during a downtrend. Most likely this is because shorts get trapped and the market runs as they scramble to cover. Mid-sized gaps are a different animal. They are not as scary for the shorts. Shorts may even see it as an opportunity to add more exposure, while longs look to take gift profits. Whatever the reason, the long-tem downtrend is generally able to re-assert itself during the day and those that bought into the early morning excitement get punished.

When deciding how to approach a gap up in the morning, make sure you consider at least two things: 1) Long-term trend of the market. 2) The size of the gap. They both matter.

What Happens When Range Rapidly Contracts

In the 1980’s Tony Crabel published research on Wide Range Bars and Narrow Range Bars. He introduced the concept of WR7’s and NR7’s. A WR7 is a bar whose range is wider then the previous 6 bars. An NR7 is a bar whose daily range is narrower than the previous 6 days. Others have done work with WR and NR bars since then including Linda Bradford Raschke and Larry Connors – both separately and together. Their book Street Smarts contains a pattern which uses historical volatility and NR4 bars to look for explosive moves.

The market’s steep selloff on Friday created a WR7 bar. On Monday the selling quieted and the market actually put in an NR7 day. While volatility tends to be mean reverting, it’s unusual to see it contract that fast. I look at the action in the NDX back to 1986 when a WR7 with a lower close was followed by an NR7 the next day. Buying on the close of the NR7 day and holding for “X” days achieved the following results:

It appears the inability of the sellers to follow-through after the wide range day down invites buying over the next several days. In the very-short term (1-3 days) the bias is strongly bullish. Consider the fact that the average day over the period tested was a 0.06% gain. The one day performance following this setup was over 10-times a normal day and over three days it outperformed and average three days by over 5-times. The high win rate and average win size consistently higher than the average loss make this setup intriguing.

A few other notes: 1) Whether the NR7 day was positive or negative had little impact on performance and was not differentiated in the results above. 2) A WR7 up bar is a less bullish setup – but I’ll look at that in more detail when the time is appropriate.

Sharp Drops In Consolidations – Bad News

Friday the market got ugly. The S&P sold of more than 2% and the NDX dropped almost 3%. My take is that we have a strong selloff within a consolidation period. The market is trading right where it has been many, many times since the 3rd week in January. The sideways action of the last 2-3 weeks is basically a continuation of the sideways action over the last 2-3 months. As most traders are aware, markets act differently depending on their overall direction. Uptrends have different characteristics than downtrends which have different characteristics than sideways markets. So I decided to take a look at market performance following a strong selloff in a sideways market. First I tested the S&P 500 under the following conditions:

1) Dropped at least 2% today.
2) Did not make a 10-day closing low. (Suggesting no breakdown.)
3) 14-period ADX is less than 20. (Suggesting congestion.)

Buying when these conditions occurred and selling “X” days later produced the following results looking back to 1960:

Negative expectations and very low % profitable. Quite negative on a small sample size even as far out as 4 weeks. For those that would like to take a closer look, here are the dates: 6/23/70,12/02/74, 1/7/81, 4/14/88, 5/14/99, 2/9/00, 1/5/01, 10/29/01, 9/12/02, 11/1/07, 12/11/07, 4/11/08.

To gain a larger sample size, I decided to look at the NDX, which historically has been more volatile. In this case I required a 2.5% drop (instead of 2%) and kept the other requirements the same – no closing 10-day low and a 14-period ADX below 20. With less historical data this test only ran back to 1986. Below are those results:

More of the same here.

Strong pullbacks in strong uptrends may be buyable. Strong pullback in consolidations, on the other hand, have historically led to more downside. Based on this study, caution seems warranted.

Mythdirection Thursdays

So Adam at the Daily Options Report on Thursday threw down the gauntlet when he said he’s never seen a study which confirmed or denied the legend of “Misdirection Thursdays”. Allegedly, whichever way the market moves on the Thursday before expirations week is counter to the general direction it will move from then until expiration. So I ran some tests.

Buying (shorting) at the close on Thursday before expirations week if the market was down (up) and selling (covering) the Friday of expirations would have netted the following results since July 1978:

Trades – 354
Winners – 171
Losers – 182 (1 breakeven)
Average trade – -0.08%

So the overall concept doesn’t seem to hold. What if we break it out by longs and shorts?

The long signals were profitable 57% of the time for an average gain of 0.24% over 6 days.

The short signals were profitable 40% of the time for an average loss of 0.39% over 6 days.

Here we see that the short signals were actually a better buy signal that the buy signals.

Relatively High Put/Call A Positive

The market finally broke its consolidation on Wednesday. One intermediate-term positive I’m seeing right now is the action in the CBOE put/call ratio. Today it closed at 1.16. Over the last 4 days it has averaged 1.12. High put/call ratios are normally associated with market selloffs, yet the market made a 20-day high as recently as Monday.

Relatively high levels of put buying are indicative of worry on the part of traders, which is why they are more common during selloffs than during upmoves. I looked back to check other times when the 4-day put/call ratio was above 1.10 and the market was within three days of a 20-day high. Looking back to 1995 I only found three instances: 8/23/06, 2/23/07, and 5/25/07.

August 23, 2006 was a great buying opportunity both short and long-term. It marked a low point and the market rallied for several months following that.

February 23, 2007 was certainly not a buying opportunity. It came just two days before the market collapsed over 3.5% on February 27th.

May 25, 2007 was followed by a 5-day rally and then an extremely choppy month of June.

Not much to learn from these three examples. It should be noted, though that the put/call ratio has been significantly higher over the past couple of years than it was in the beginning of the decade. To adjust for this I normalized the data by using the 100-day moving average.

I once again looked at any time the S&P 500 had made at least a 20-day high in the last 3 days. This time I only required that the four-day average put/call ratio was above its 100-day moving average. After eliminating overlap and looking out at least 20-days I found 47 instances going back to 1995. 33 of these led to positive returns over the next 20 days and 14 of them led to declines – a 70% win rate. The average win was 2.7% and the average loss was 2.5%. The average trade was 1.1%. Not overwhelming numbers by any stretch but not bad, especially considering the market was already at a 20-day high.

In all I would consider the relatively high put/call ratios we are currently seeing a positive. They may help to provide a “wall of worry” for the market to climb.

A Rooster Egg Market

I remember a riddle from when I was a kid that went something like this:

Q: If a rooster lays an egg right at the very peak of the roof of the barn while facing north and the roof slopes east and west, which way will the egg roll?

A: It won’t. Roosters don’t lay eggs.

Now for the market:

Q: If the S&P shoots up 2.5% or more in one day and then closes within 0.5% of its closing price the next five days in a row, which way will the market break?

A: The S&P doesn’t do that…until now.

Here’s a line chart of the S&P 500.

I see no short-term edge.

In other news, Alcoa (AA) released earnings Monday night. They disappointed and sold off a little bit on Tuesday. Alcoa’s earnings release always comes with great fanfare because it’s typically the first large-cap to report after the end of the quarter. Does it really deserve all the fanfare? Is it somehow predictive of how the market may perform during earnings season? I figured it was worth a look.

The test was run as follows. I looked back at the last 25 earnings announcement for Alcoa. If Alcoa rose following its earnings announcement I bought the S&P 500 and held for 25 days. If Alcoa fell following its earnings announcement I sold short the S&P 500 and covered 25 days later. Results below broken out by buys and sells:

Buys: 9, Winners: 5, Losers: 4
Shorts: 16: Winners: 9, Losers: 7

From this limited test it appears the reaction to Alcoa’s earnings is about as important to the market as scoring first is in a basketball game.

What’s a trader to do when they can’t identify a clear edge in their timeframe/market? Some thoughts on what to do between trades from Dr. Steenbarger might help.

How The Subscriber Letter Fared In March

A little delayed I’ve posted below some statistics for the first month plus of the Subscriber Letter. March was a terrific month for the Letter.

Note – this is not a performance record. I do not make recommendations in the Subscriber Letter. This is simply a listing of trade ideas. Past performance is not necessarily indicative of future results. March may turn out to be the best month ever.

A few notables I should point out:

First, some trades ideas are scaled in to. Therefore you may see more than one position in the same security on at the same time. If the method calls for scaling in, it is most commonly done in up to 3 parts.

Subscribers also receive intraday updates on many open trade ideas. The intraday updates are not reflected in the overall statistics. For instance, I sent out an update on the XLV and PPH trades above on the morning of 3/7 when they gapped up. It indicated that certain targets had been reached and traders could consider exiting these trades prior to the Monday open when the “official” exit prices would be determined. Both trades were profitable at the time of the update. A similar scenario occurred with a few stock trades during March as well, where late-day selloffs and gaps down caused hits to the official stats, while many subscribers were able to fare much better.

A Look At Some Negative Reversal Bars

We saw a few examples of positive reversal bars at work in the first quarter. On Monday the market formed a negative reversal bar. Below are descriptions of what I saw in the NDX and the SPY and the action of the market following similar setups in the past:

Choppy trading over the next day or two has led to a downside edge once the market is 3-5 days out from these bars. Combined with the low VIX and the overbought readings of some indicators, caution seems warranted here.

Quantifiable Edges Identified in Q1

With the 1st quarter behind us I thought a summary of what we learned on the blog through the studies would be interesting. (You should also note that most of these studies are now available in the 1st Quarter 2008 Quantifiable Edges Studies Package for Tradestation users.)

If the VXO spikes higher and the market doesn’t rebound…look out below!

Some kinds of reversal bars really do work. And so do others.

IBD Follow Through Days provide an edge – but it’s not as advertised. (FTD’s are not included in the 1st Quarter Studies Package but will be separately available soon.)

When time gets stretched, price reversals are typically close at hand.

When capitulating markets bounce, it’s the most beat up stocks that bounce the highest. (Not included in Q1 package -study done outside of Tradestation.)

When the Nasdaq and Russell get disjointed it typically means volatility and rising prices.

Large gaps in downtrends should be bought. Both down and up. (Not included in package – done mostly outside of Tradestation).

Big Arms can lead to next day buying.

Inside Days have a tendency to lead to short-term downside.

Some contracting ranges suggest more upside.

3 up days in a downtrend tend to lead to selling.

Failed gaps aren’t as bad as they seem.

Triangle breakouts are highly unreliable and may provide an edge to fade.

A late surge may or may not carry over to the next day.

Not all breakouts are good.

Nasdaq Leadership can be important.

There is a recent edge on the 1st trading day of the month.

Four months lower doesn’t mean we’re going up.

More proof reversal bars work.

Put/call ratios can help signal a reversal is near.

Stretched VXO readings are generally a short-term positive for the market.

New low divergences are nice but not overly positive.

Strong moves off bottoms can lead to intermediate-term rallies.

Sharply declining consumer sentiment tends to precede stock market lows.

Fed rallies tend to be short-lived.

Overbought in a downtrend can lead to some nice shorts.

Light volume on a pullback isn’t necessarily positive.

The market doesn’t get marked up on the last day of the quarter.

And a few more.

In all, there are 45 studies included in the Quantifiable Edges 1st Quarter package. At a time when programmers charge $100 – $150/hr, I’m offering the entire package for $195. That’s about $4.33 per study. All open coded. Flexible inputs for further research. Ready-to-import data files for those studies that need it (like the Consumer Sentiment Index study). If you want to test you own ideas in Tradestation, this group of studies can also provide some nice templates to work with. Click here to purchase and you can download and import the studies and workspaces into Tradestation in just a few minutes.

I’ll bet the 2nd quarter teaches us just as much as the 1st…


After shooting up 3.5% last Tuesday the S&P 500 has flat-lined. The chart might make you think there was a takeover announced last Tuesday morning of all 500 components. Volume has dropped each day as well.

I looked back over the last 30 years for similar price action. The only other time the market followed a gain of 3% or more with 3 consecutive closes within 0.25% of the close of the 3% day was December 3, 1982. By lowering the requirement of the surge day from 3% to 0.75% I was able to get a larger sample size. A summary of those instances is in the table below.

One day out falls basically in line with random. Two to three days out there appears to be a slight upside edge when this occurs.

Below are the results if you eliminate the surge day all together and just require the coiling action to occur above the 10-day moving average.

Again, slightly better than random over the 1st three days. Nothing to exciting here, but another small hint at higher prices.

What The Low VIX May Be Indicating

With all the recent volatility in the market, many traders have noted the recent low VIX levels and wondered if that was a sign of complacency. Low VIX readings relative to their short-term moving averages do sometimes presage market pullbacks. While one use of the VIX is trying to predict the direction of the market. That really isn’t what the VIX represents. It represents options traders perception of future volatility. So perhaps the low VIX means they know something?

One of the most unusual aspects of the recent environment is how volatile it has been in a virtually trendless market. Wild swings within a range. Lots of chop. To quantify this action I took the 14-day ADX of the SPX (15.56) and divided it by the 14-day historical volatility (volatilitystddev in Tradestation terms), which currently stands at 0.3023. The result (about 51) is what I call trend over volatility (TOV). Charting this helps to see other times where volatility was high and the market wasn’t trending.

Going back to 1960 I was only able to find 5 other periods where the TOV was below 55. Looking at the performance of the market “X” days out gave the following results:

Four pretty strong winners and one sizable loser. Interesting, but perhaps not compelling enough for a directional bet on its own. (Combined with my other recent studies it may be.)

To try and glean a little more I looked at the charts. The top line is TOV. The yellow line is ADX. The blue line is Historical Volatility. The vertical line shows when the TOV dropped to 55 or lower. (Click charts to enlarge.)

October 2002

January 2001

February 1999
January 1988

October 1987

The one thing that stuck out to me? In every case, at some point in the next month there was a sharp drop in historical volatility. In ’87 and ’88 it took about 3 weeks. The other times it was almost immediate. Does the VIX know something? It just might.

Perhaps those uncomfortable with directional bets in the current market might prefer to use options and bet on a reduction in volatility.

I haven’t done too much with this indicator yet, but I suspect it could have applications for individual stocks as well.

Tradestation users who wish to play with this indicator and concepts more may purchase and download the indicator, study, and workspace at the studies section of the Quantifiable Edges website for $12.00. I made the inputs for length on both ADX and Historical Volatility flexible so that it can easily be fine tuned.

Will The Employment Report Cause Large Range Expansion?

Compared to the recent volatility the last two days have been very tame. One line I’m hearing is that traders didn’t want to take big bets before Friday’s employment report. The expectation seems to be that the employment report will spark a big move Friday one way or the other.

To test this I compared the 2-day average true range with the 20-day average true range. The ratio as of Thursday’s close in the SPY was about 0.53. I ran a test to see what happened when this ratio had dropped below 0.55 or lower going into a report. The basic expectation was that the contraction in volatility would reverse after the news was released and lead to an explosion in volatility.

That did not hold true. The table below shows the results.

The third column shows the true range on the day of the release vs. yesterday’s 20-day average true range. The average for the 9 instances was 0.94 – meaning the true range after the report failed to reach even average size (1). In the last column I showed the percentage gap that SPY opened the next morning.

You’ll probably hear a lot of hype about the importance of the number Friday morning. Don’t be too surprised if it turns out to be just that – hype. Historically after such contractions it hasn’t led to the volatility explosion that you might expect.

If you would like to explore the action leading up to and on employment days in more detail and you use Tradestation, you may purchase the study here.

How Markets Really Work – Free

I’ve had the pleasure of doing some work with and for Larry Connors. His ideas have inspired a good amount of the work I’ve done over the last several years. I’ve mentioned before his book “How Markets Really Work”, which has many interesting facts and observations in it. When I went to the TradingMarkets site today I noticed they were allowing free downloads of the book until Monday night. I’d highly recommend people download and read it. Here’s the link:

How Markets Really Work

Consolidating Gains

Today’s action didn’t appear spectacular in any way. The market consolidated its gains on ho-hum volume. While my blog yesterday indicated Tuesday’s big gains served as further confirmation that the market was likely to continue higher for at least a few weeks, the short-term is not as bullish. Most of the time there is some brief give back after such large moves.

I ran some numbers tonight looking at action immediately following up days of 3.5% or more in the S&P 500. Of the 35 instances since 1960 that my scan found, 31 of them traded lower than their thrust day close at some point in the next 5 days. (Make that 32 for 36 after Wednesday.) 18 of the 35 traded lower by 1.75% or more.

What’s this tell me? The pullback today was normal. In fact, continued pullback would be normal. The last two big thrust days (3/11 and 3/18) the market fell hard and fast almost immediately. If the market can get through tomorrow without a sharp selloff, that could be a positive. It would be a change in character.
