The SPY‘s (S&P 500 SPDR) closed modestly lower on Monday, October 4, 2010, at the same time the 2nd session of the month, and regularly – being part of the positive turn-of-the-month effect – , a positive day for the markets (but not this time).
But historically a modestly lower close on the 2nd session of a month has positive implications for the SPY‘s performance the next day.
Table I below shows all historical occurrences and the SPY‘s (S&P 500 SPDR) respective intraday performance (since 01/01/1990) on the open (open vs. previous close), the intraday high in comparison to the previous session’s close (high vs. prev. close), the intraday low in comparison to the previous session’s close (low vs. prev. close), at the end of first hour of the session in comparison to the previous session’s close (1st hr. vs. prev. close), and on the close (close vs. prev. close), in the event the SPY lost between -1.0% and -0.50% on the previous session’s close (like on Monday, October 4, 2010).
Out of 28 occurrences, the SPY opened higher the next day (in this event on Tuesday, October 5) on 21 occurrences (or 75% of the time), was always trading above the previous session’s close at least once during the next session (no unfilled gap on the downside), left an unfilled opening gap up on 8 occurrences (or 25% of the time), was never trading lower than -0.66% at the end of the first hour of the session, and finally closed higher on 19 occurrences (or 67.86% of the time), and downside potential on the close was regularly limited as well (max. loss -1.14%).
Successful trading,
Frank
