Trading the Odds on Thursday – May 28, 2009


The S&P 500 fully complied to today’s bearish forecast based on the negative setup triggered on Tuesday’s session when the ratio of NYSE Advancing Issues/Declining Issues closed above 4.5 and NYSE Advancing Volume/Declining Volume closed above 5.5 on the same day (see my post Trading the Odds on Wednesday – May 27, 2009).

The S&P 500 closed lower -1.90% on the day, and what looked like a positive divergence between a relatively strong breath and a relatively weak index approximately 90 minutes before the close (NYSE TRIN in bullish territority < 1.0 when the S&P 500 was already dwon more than -1.0%, see my Twitter update) finally turned into a session with breath significantly lopsided on the downside. NYSE Advancing Issues/Declining Issues closed at 0.44, and NYSE Advancing Volume/Declining Volume at 0.24 (NYSE TRIN at 1.81).

But although the S&P 500 closed significantly lower on a very week breadth, especially remarkable was the fact that the S&P 500 nevertheless posted a higher high than Tuesday’s high and a higher low than Tuesday’s low which triggered a short-term buy signal on Wednesday’s close.

At first Table I below shows the ES (S&P 500 E-MINI) performance (since 01/02/1990) concerning setups S1 to S5 -side by side- on the next sessions assumed one would have bought the ES on close of the respective session where setups S1 to S5 had been triggered. Setups S1 to S5 are defined as

Table I

  • Setup S1: the S&P 500 closed lower at least -1.90% on the day
  • Setup S2 the S&P 500 posted a higher high and higher low than the previous session’s high/low
  • Setup S3: NYSE TRIN closed above 1.80
  • Setup S4: Setups S1 und S2 combined
  • Setup S5 Setups S1 und S3 combined


It is especially notable that on the session immediately following those sessions where the S&P 500 had either closed lower at least -1.90%, or the NYSE TRIN closed at 1.80 or higher, or especially where the S&P 500 not only closed lower at least -1.90% but posted a higher high and higher low as well, probabilities for a higher close and odds (expectany / pay-off) are significantly tilt in favor of the bullish side (a short-term snap-back).

Table II below now shows the ES (S&P 500 E-MINI) intraday performance (since 01/02/1990) concerning the open, high, low, close (compared to the previous’s session close) and close versus open on the next session (in this event Thursday, May 28) immediately following those sessions where the S&P 500 not only closed lower at least -1.90% but posted a higher high and higher low as well.


It is especially notable that -although the sample size is way too small to read any statistically relevent into it- the market shows a tendency for a weak open (3 sessions with a higher open, 5 with a lower open, but the average lower open is down -0.95% compared to an at-any-time lower open of -0.38% only), but a remarkable tendency for some intraday strength as well with an average intraday high +1.87% above the previous session’s close, and finally with 7 higher and only 1 lower close.


Bottom line:

  1. Today’s magnitude of change on the downside (-1.90%), the weak breadth (NYSE TRIN at 1.80) and the higher high and higher low on today’s session triggered a short-term buy signal on the close, and any weakness on Thursday’s open will probably provide a favorable short-term (intraday) buying opportunity.

Successful trading,
