Intraday Odds for Tuesday, November 23

On Monday, November 22, the SPY recouped almost all of its intraday losses of -1.26% into the close and ended the session with a fractional loss of -0.08%. But at time of writing (Tuesday, November 23, 2:38 am ET), the ES E-mini (S&P 500) future is (again) down -0.90% (-10.80 index points).

Historically with a combination of both – the market’s ability to recoup an intraday loss of -1.0% (or more) into the close and a significantly lower open on the then following session – , probabilities and odds are heavily tilt in favor of some additional intraday downside.

Table I below shows those occurrences and the SPY‘s historical intraday performance (since 01/01/1990) on the open (‘open vs. prev. close‘), the intraday low (‘low vs. previous close‘), during the first hour (‘1st hr. vs. open‘), the close vs. the end of the first hour (‘close vs. 1st hr.‘), and on the close (‘close vs. prev. close‘) on those sessions where the SPY opened lower at least -0.75% (possibly on Tuesday, November 23) immediately following a session where the SPY had posted an intraday low of at least -1.0%, but closed in the top quartile of the intraday range (like on Monday, November 22) in the past.

Interesting to note that the SPY

  • … posted an intraday low of at least -2.0% on 21 out of those 28 occurrences (or 75.00% of the time) ;
  • … showed a positive performance during the first hour on 17 occurrences (or 60.71% of the time), but a significantly negative performance during the rest of the session (after the end of the first hour) on 22 occurrences (or 78.57% of the time) ;
  • … lost at least -1.0% or more after the end of the first hour of the session on 15 occurrences (or 53.57% of the time) ; and finally
  • … closed lower on 27 out of up to now 28 occurrences (or 96.42% of the time).


From a statistical and historical point of view – assumed the SPY will open lower at least -0.75% on today’s session – , chances for another upside reversal on Tuesday, November 23 are slim, and any upside during the first hour of the session might provide a selling (shorting) opportunity targeting (partly significantly) lower prices during the rest and / or at the end of the session.

Successful trading,
