On Wednesday’s session, and with respect to the SPY (SPDR S&P 500 ETF), Wilder’s Relative Strength Index (RSI) for a 2-day period closed above 95 the sixth day in a row, and above 99 on the fourth consecutive session.

With respect to the latter, the last occurrence dates back 15 years (see stats below), which – at least with respect to historical probabilities and odds – might have positive implications looking out 10 sessions ahead.

Table I below shows the SPY’s historical performance (since 01/01/1990) over the course of the then following 1, 2, 4, 5 and 10 sessions assumed one would’ve bought the SPY on the close of a session when the RSI(2) closed above 99 on the fourth consecutive session.

Interesting to note that historical probabilities favor a continuation of the uptrend over the course of the then following 10 sessions. After four consecutive RSI(2) readings above 99 (on the close), the SPY closed higher 5 sessions later on 12 out of 14 occurrences, and was never trading (intraday, not only on the close) lower than -1.46% below the trigger day’s close over the course of the then following 5 sessions, so historically downside potential was more or less not existent. In addition, the SPY was trading higher 10 sessions later on 11 out of those 14 occurrences, and did never close lower greater than -0.29% below the trigger day’s close.

And on a session immediately following a fourth reading above 99 (in this event on Thursday, March 11), the SPY never lost more than -0.33% on the close, although one should be carefull to read anything statistically relevant into something with 14 occurrences only over the course of 20 years .

But with Distribution of Returns (represents where the setup’s median return is ranked in comparison to the – ranked in descending order – median at-any-time return) only slightly above/below the 50% mark, none of those occurrences being part of the top 10% best and worst performing at-any-time sessions, and the SPY closing higher greater than +1.0% five sessions later on only one out of those 14 occurrences, upside potential will probably be limited as well, so a sideways trading, rangebound marked with an upside bias seems tto be he most likely outcome.

Almost the same conclusion can be drawn with respect to historical occurrences where the RSI(2) closed above 95 on six consecutive sessions. Table II below shows the SPY’s historical performance (since 01/01/1990) over the course of the then following 1, 2, 4, 5 and 10 sessions assumed one would’ve bought the SPY on the close of a session where the RSI(2) closed above 95 on the sixth consecutive session.

Historically on a session immediately following a sixth reading above 95 (in this event on Thursday, March 11), the SPY never lost more than -0.47% on the close (24 occurrences), and did never close lower than -0.43% below the trigger day’s close 4 sessions later. And out of those 24 occurrences, the SPY has always posted at least one higher high than the trigger day’s intraday high over the course of the then following 10 sessions.

Successful trading,
Frank

First of all it seems that the bullish setup triggered on Friday, February 19, 2010 (five consecutive sessions with an RSI-High/Low (2-day) closing above 95, see my posting Modified RSI(2), Buying Power and Intermediate-Term Outlook) is currently playing out quite nicely.

The setup called for a higher close 5, 10, 15 and 20 sessions later based on an unbroken streak of sessions with a close at least in the upper half of the daily trading range, regularly close to the respective intraday high (buyers are  consistently overwhelming sellers during the second part of the respective sessions).

Table I below shows the SPY’s historical performance (since 01/01/2005) over the course of the then following 1, 5 , 10, 15 and 20 sessions (1 month later) assumed one would’ve bought the SPY on the close of a session when the signal (5 consecutive sessions with an RSI-High/Low (2-day) above 95) had been triggered in the past:

Since 01/01/2005 (25 occurrences) the SPY was always trading at a higher level one month later (in this event on March 19, 2010), and never lost more than -0.20% three weeks later (in this event on March 12, 2010).

______________________________________

But now to another seasonality which I haven’t noticed (I didn’t find any postings about potential abnormalities around the SPY’s ex-dividend days as well) until I made some adjustments (and minor corrections) to my Matlab coding in order to account for SPY dividend and cash deductions in the correct manner.

Table II below shows the SPY’s historical performance on the then following session after the following setups had been triggered in the past (since inception of the SPY on 01/22/1993):

• (Setup 1) the session immediatley preceding a SPY’s ex-dividend day (the output is the SPY’s performance on an ex-dividend day)
• (Setup 2) SPY ex-dividend day (the output is the SPY’s performance immediately following an ex-dividend day),
• (Setup 3) SPY ex-dividend day, and the SPY closed up as well,
• (Setup 4) SPY ex-dividend day, and the SPY and the S&P 500 posted contradictory signs concerning their respective end-of-day performance (SPY up and S&P 500 down, or vice versa),
• (Setup 5) SPY ex-dividend day, and the SPY’s and the S&P 500’s end-of-day performance differed by at least 0.25%.

It is interesting to note that

• probabilities and odds on a SPY’s ex-dividend day are (heavily) lopsided on the upside, while probabilities and odds on a session immediately following a SPY’s ex-dividend day are (equally) lopsided on the downside, especially in the event of a higher close on an ex-dividend day,
• since inception of the SPY on 01/22/1993 there were 10 occurrences where the SPY closed up and the S&P 500 closed down (or vice versa) on a SPY’s ex-dividend day, and on all 10 occurrences the SPY closed lower on the then following session, and last but not least
• since inception of the SPY on 01/22/1993 there were 39 occurrences where the SPY’s the S&P 500’s end-of-day performance differed by at least 0.25% on a SPY’s ex-dividend day, and on 31 out of those 39 occurrences the SPY closed lower on the then following session.

In order to account for any potential data and/or coding issues (especially with respect to the SPY’s dividend and cash deductions and respective end-of-day performance), I thought it would be mandatory to verify these stats at least with one other index’ performance data (without any dividend and/or cash payments).

Table III below shows the Russel 2000’s historical performance on the then following session after the setups listed above had been triggered in the past (means the SPY and the S&P 500 were only used as a trigger while performance stats are derived from the Russel 2000’s historical performance):

The SPY and the Russel 2000 show only (if any) minor deviations (quite comparable to the at-any-time deviations in their respective end-of-day performance) in their respective performance stats, so the hypothesis of any data and/or coding issue with respect to the SPY’s and/or S&P 500 end-of-day performance and data may be rejected.

At least based on the respective t-scores, chances that these abnormalities occurred by pure chance only are very small. A rationale for setup 1, 2 and 3 could be that commercial and institutional traders/investors seem to be interested to hold the SPY on an ex-dividend day (may be due to tax reasons), and to immediately get rid of their invest on the then following session (especially in the event of a higher close), but I don’t have a rationale for the statistical abnormalities behind setup 4 and 5.

Successful trading,
Frank

With Wednesday’s session, the SPY posted a second consecutive higher close, but closed below the open (a black ‘candle‘) on both sessions.

Although initially one might consider this market behaviour as a short-term bearish pattern, historical occurrences and respective probabilities and odds tell a different story.

Table I below shows the SPY’s historical intraday performance (since 01/01/1990) on the  the intraday low, during the first hour of the session, at the start of the last hour in comparison to the previous session’s close,  during the last hour of the session and on the close whenever the SPY had posted two consecutive higher closes in the past, but closed below the open (a black ‘candle‘) on both sessions:

Interesting to note that historically on the then following session (in this event on Thursday, March 4), the SPY

• left an unfilled opening gap up (an intraday low above the previous session’s close) buyers on 9 out of 27 occurrences (every third session), significantly above the at-any-time odds for leaving an unfilled opening gap up,
• showed a positive performance during the first hour of the session on 25 out of 27 occurrences (historically downside momentum during the first hour was almost non-existent),
• was trading at a higher level (in comparison to the previous session’s close) at the start of the last hour again on 25 out of 27 occurrences,
• closed higher on 23 out of those 27 occurrences,
• but (repeatedly after already having posted two consecutive closes below the open) showed a negative performance during the last hour of the session.

Regularly whenever the setup had been triggered in the past, the weakest part of the then following session was the open, historically providing a favorable intraday and short-term edge on the long side of the market right at the start of the session. But take into account that 27 occurrences is not something to read anything statistically relevant into it (although probabilities and odds are heavily lopsided on the bullish side at least between the open and the start of the last hour of the session), and a couple of other pattern suggest at least a modest consolidation (a down day) on Thursday’s session.

Successful trading,
Frank

P.s.: The Market Model is short going into Thursday’s session due to the fact that everything else except the pattern discussed above suggests a down day.

The RSI-High/Low(2) indicator seems to provide a good indication that buyers will not let the market go down without a fight (see my posting Modified RSI(2), Buying Power and Intermediate-Term Outlook ).

But today’s recovery from a significant intraday low of -1.70% and a close not lower than -0.25% (the SPY recouped more than -1.50% of it’s intraday losses into the close) does – from a historical and statistical perspective – not provide a positive indication for Friday’s potential performance during the session and on the close.

Table I below shows the SPY’s historical intraday performance (since 01/01/1990) on the open, the intraday low, during the first hour of the session, during the last hour of the session and on the close whenever the SPY had posted an intraday low of at least -1.70% below the previous sessions close in the past, but did not close lower than -0.25% on the day in conjunction with a close in the top 10th percentile of it’s daily intraday range (almost on the high):

Interesting to note that although on Friday’s session there is a good chance for an early (first hour) follow-through of today’s (Thursday’s) late strength, sellers regularly take the upper hand again during the second part of the then following session.

The SPY’s last hour’s performance following a session when this setup had been triggered in the past is everything else than bullish: four sessions with a positive and 20 sessions with a – partly significantly – negative performance during the last hour (the SPY lost at least -0.50% on 17 out of those 20 sessions with a negative performance during the last hour), and a lower close on 17 out of the total of 24 occurrences since 1990 (the last time the setup was triggered was on 02/05/2010).

But as always: Everything is possible but not necessarily probable.

Successful trading,
Frank

During the last couple of sessions almost all major US market indices showed a remarkable strength concerning their ability to not only recoup almost all of their intraday losses (like on last Friday’s session), but to close above the open as well. For exemplary purposes: The Russel 2000 now posted a series of 8 consecutive sessions with a close above the open (a white candle).

I thought it would be interesting to check if – and to what extend, and as always from a historical perspective – this positive abnormality could provide a potential short- and intermediate-term edge, either on the long or the short side of the market.

In order to ‘quantify’ the markets (historical) strength with respect to a close above the open and/or above the midpoint of the session, I utilized Wilder’s Relive Strength Index, but with a minor adaptation:

The modified (2-day) RSI now will not be based on the change between the current and the previous session’s close, but measure the underlying’s performance (buying power) with respect to the midpoint of the session, means a close above the midpoint would represent a positive percentage-wise performance, a close below the midpoint a negative percentage-wise performance.

Wilder’s original formula: change = today’s close – yesterday’s close

Adaptation: change = (today’s close – today’s low) + (today’s close – today’s high)

Everything else (with respect to the computation of the Relative Strength Index) remains unchanged.

With Friday’s session, the RSI-High/Low(2) closed above 95 on five consecutive sessions, and closed above the previous session’s RSI-High/Low(2) the fivth day in a row as well.

Table I below shows the SPY‘ historical performance (since 01/01/2006) over the course of the then following 1, 5 , 10, 15 and 20 sessions (1 month later) assumed one would’ve bought the SPY on the close of a session when the signal (5 consecutive sessions with an RSI-High/Low(2) above 95) had been triggered in the past:

Interesting to note that although the SPY might take a short break from it’s recent upmove on Monday’s session (a modest pullback seems likely, but the SPY did never loose more than -0.75% on the then following session out of those 21 occurrences), any potential weakness at the beginning of next week will probably represent an intermediate-term buying opportunity. At least since 01/01/2006 (the last 21 occurrences), the SPY closed at a higher level (above the trigger day’s close) 5 sessions later on 18 out of those 21 occurrences, and 10 and 20 sessions (1 month) later on 20 out of the last 21 occurrences.

And chances that the SPY will post at least one lower close (below the trigger day’s close) over the course of the then following 20 sessions are more or less even only (57.14% to be exact, that means in 9 out of those 21 occurrences the SPY never looked back), significantly below the at-any-time (since 01/01/2006) probability for at least one lower closer over the course of the next 20 sessions.

In addition (besides the probabilities for a higher/lower close x sessions later in comparison to the respective at-any-time probabilities), historical odds are heavily lopsided in favor of the long side of the market: One month later (20 sessions), none of those 21 occurrences were among the top 10% of the worst performing at-any-time sessions 20 session later, while 4 (19%, significantly above average of 10%) were among the top 10% of the best performing at-any-time sessions.

So at least with respect ot the recent history, after possibly taking a short breather (if any), a resumption of the recent upmove seems more than likely.

Successful trading,
Frank
