A Seasonal Look At October Op-Ex Monday

Posted by in Quantitative Study, seasonality October 15, 2012

Opex week during October has typically been a strong week for the market.  This can be seen in our op-ex week breakdown by month from March.  And much of the upside edge has been thanks to the strong op-ex Monday returns.  But op-ex Monday in 2008 was SO unusually strong (11.5% 1-day gain) that I decided to run the numbers excluding it.  So here is a look at October op-ex Mondays since 1984 not including 2008.

As you can see the numbers are still very favorable.  There appears to be a bit of a bullish seasonal edge today.

A Bounce Study Suggesting More Downside

Posted by in Quantitative Study October 12, 2012

In an older study in the Subscriber Letter I looked at bounces after SPX is strongly short-term oversold as measured by RSI(2).  What I found in that letter was that lower-volume instances on the first day of the bounce have performed much better over the next few days than higher-volume bounces.  I won’t rehash the whole study here, but I will show performance following higher volume bounces like Thursday.

As you can see, it appears that such bounces suggest a short-term downside edge.

One reason the blog has been slow this week is that I am preparing for my trip to Atlanta next week to speak at the MTA meeting there.  If you’re in the Atlanta area and would like more info on my talk you may check out the link below.  You don’t need to be an MTA member to attend, but you should consider joining.

A Columbus Day Edge Revisited

Posted by in Quantitative Study, seasonality October 7, 2012

While the stock market is open on Monday, banks, schools, government offices, and the bond market are closed.  In past years with the bond market closed, the stock market has done quite well on Columbus Day.  Of course the most famous Columbus Day rally was in 2008 when the market gained over 11% after having crashed the week before.  Last year in the 10/10/11 blog I showed that positive momentum leading up to Columbus Day has generally led to a positive Columbus Day.  Columbus Day has been celebrated on the 2nd Monday of October since 1971.  Below is an updated version of last year’s study.

I’ve circled some of the more impressive stats here.  With 77% of trades profitable and winners twice the size of losers risk/reward has been very favorable.

What Yesterday’s VIX Action Hints At For Today

Posted by in Quantitative Study, VIX October 2, 2012

Somewhat unusual about the rise in the SPX Monday was that it was accompanied by a rise in the VIX as well.  Most of the time they mirror each other.  One quirk with the VIX is that it has a tendency to fall on Fridays and rise on Mondays. Therefore this setup is more common on Mondays than any other day of the week. The table below examines performance on Tuesdays after this has occurred.

I only show 1-day results here because anything longer shows no inclination.  And while the edge here isn’t terribly strong, it is interesting that the VIX’s inclination to rise on Mondays does not seem to completely eliminate the tendency for the SPX to pull back the next day.  Of course if this setup happens on a Friday, then the downside edge is more pronounced.

This Pattern Has Always Led to Higher Closes for SPY

Posted by in Quantitative Study September 28, 2012

The price action in SPY showed some real strength in that it gapped up, never filled, and closed above the open.  When the market is coming off an oversold level in an uptrend and is still not overbought, this pattern will often be followed by further gains.  This was shown in the subscriber letter last night (click here for a free trial).  And in the 5/22/12 letter I also showed that when the SPY pattern occurs following a short-term low it appears to provide a bullish edge, but when it occurs after an intermediate-term low then the bullish inclinations no longer hold true.  The current setup is bullish and I have updated the stats below.

The reliability and the size of the moves are both impressive.  This study suggests the rough start this morning is likely to be overcome in the next few days.

Turnaround Tuesdays Revisited

Posted by in Quantitative Study, seasonality September 25, 2012

 

It’s been a while since I updated the Turnaround Tuesday study, so I thought I would do so today.  The stats tables below all show results of buying at the close when SPX is down for a certain number of days and the exiting the following day.  The results are broken out by day of the week.  Note that the day listed is the trigger day – not the performance day.  So the Monday trigger tracks Tuesday’s performance.  Tuesday’s trigger tracks Wednesday’s performance…and so on.

In every case Tuesday has shown the most gains – hence the Turnaround Tuesday reputation appears well earned.  Though it wasn’t the highest percentage in every case, it was the strongest day on average.

Interestingly, I this time I also looked at instances where the SPX had pulled back more than 3 days.  Those results are shown below.

Under conditions of a 4 day or greater pullback Tuesday has disappointed.  Monday has been the standout winner.

The Weakest Week (updated)

Posted by in Quantitative Study, seasonality September 23, 2012

Last year I showed that the week following September options expiration has historically been the most bearish week of the year. 2011 didn’t do anything to make the stats look any more bullish.  Below is an updated chart showing the persistently poor performance since 1961.

As you can see the bearish tendency has been pretty consistent over the last 51 years.  There was a stretch in the late 80’s where there was a series of mild up years.  Since 1990 it has been pretty much all downhill.

What Friday’s VIX Action Hints At

Posted by in Quantitative Study, VIX September 17, 2012

Even with the SPX rising Friday, the VIX managed to close up a bit. The VIX will typically trade in a direction opposite the SPX, so it is unusual that they both close higher. On Fridays, the VIX has a natural tendency to dip in the afternoon, so it is most unusual to see them both close higher on Friday. The study below was last seen in 4/30/12 subscriber letter. It examines other instances of the VIX and SPX both closing higher on a Friday while the SPX is in an uptrending market. All stats are updated.

As you can see, there appears to be a decent downside edge suggested by this study. That edge has primarily played out over the first three days.

When The Fed Sparks A Rally To A Long-Term High

Posted by in Fed Study, Quantitative Study September 14, 2012

In “The Quantifiable Edges Guide to Fed Days” I discussed Fed Days that close at new highs.  The basic finding was that when the market closed at a short-term high on a Fed Day, then it was likely to pull back over the next few days.  But when it closed at a long-term high, then the rally was likely to continue.  Below is a study from the guide that.  I’ve updated all the stats.

This suggests further upside is likely over the next 1-2 weeks.

The Impact of Intermediate-Term Highs on Fed Day Performance

Posted by in Fed Study, Quantitative Study September 12, 2012

Tomorrow is a Fed Day. As I have discussed many times, Fed Days generally carry an upside tendency. But this tendency is greatly impacted by certain variables. A large collection of these variables may be found here on the blog under the “Fed Day”label. And many more may be found in the “Quantifiable Edges Guide to Fed Days”.


One variable I showed in January was whether the market was already at an intermediate-term high. There is a decent chance the market closes at a new high today so I’ve decided to update that study.


First, let’s take a look at SPX performance on Fed Days when the SPX has NOT closed at a 20-day high the day before.

That’s basically 30 ½  years of bullishness.


But now let’s see performance at times when the SPX did close at a 20-day high the day before.

No consistency and no pronounced edge in this sample of 37 instances.


Traders looking to play for a short-term Fed Day bump should perhaps be hoping the SPX does not close at a new high today.

A Pattern Of Strength Suggesting More Strength To Come

Posted by in Quantitative Study September 10, 2012

Short-term strength is often followed by short-term weakness, but when that short-term strength is unusually impressive, it can create a situation where that extreme strength will beget more strength. When the market leaves an unfilled up gap that is considered a sign of strength.  When it does it 2 days in a row and closes at a 50-day high, that can be considered exceptional strength. That is what happened on Friday, and past performance is shown in the study below.

The size of the follow-through isn’t terribly large. But it has been very, very consistent that at least some follow through was achieved in the next few days.

One Strong Short-Term Positive About Thursday’s Breakout

Posted by in Quantitative Study September 7, 2012

In the 7/19/12 blog I looked at the short-term importance of an unfilled upside gap accompanying a breakout.  With yesterday’s breakout occurring along with an unfilled up gapI have revisited that study below.

Results here are strong across the board.

Now let’s look at instances where the 50-day high breakout was not accompanied by an unfilled gap.  Interestingly, the number of instances was nearly the same.  This study also appeared in the 7/19/12 blog and is updated.

As you can see these moves to new highs that don’t start with an unfilled gap are much less reliable over the short-term.

Technicians will often use the term “breakaway gap”.  This suggests the gap occurs on the same day as a base breakout.  The idea is that the new high causes excitement and the gap leaves a good amount of people sidelined or stuck short.  When it doesn’t immediately fill, it leads these people to chase and helps to propel the market even higher.

Interesting Implications of the RUT/SPX Divergence on Tuesday

Posted by in Quantitative Study September 5, 2012

Last night in the Quantifiable Edges Subscriber Letter I examined short-term implications of strong 1-day rises in the Russell 2000 (RUT) while the S&P 500 (SPX) declined. I found that there appeared to be a decent upside inclination for the following day. This morning I played around with this concept a little further, added a filter that eliminated instances occurring in conjunction with intermediate-term lows, and ran the test out longer. What I found was quite interesting and can be seen in the stats table below.

While 1-day implications appear bullish, looking out over the next couple of weeks there has been a strong downward tendency. This may be worth keeping in mind over the next 10 days or so.
