Implications of Fear ($VXO) and a Lower Close

Again a couple of news from China and Italy (Italy 10-Year Bonds up over 10% this morning) are driving markets lower today. At time of writing (01:00 PM ET) the SPY is down -2.24%, while the S&P 100 Volatility Index (VXO) – like the S&P 500 Volatility Index (VIX) better know as the Fear Index – is up more than 20.0%.

Should this sell off actually persist into the close, a favorable trading opportunity might be presented on tomorrow’s (Thursday, November 10) session (in fact on a lower open or additional weakness on the GLOBEX overnight session). Table I below shows all historical occurrences and the SPY‘s intraday performance on the then following sessions (in this event  on Thursday, November 10) in the event the VXO closed higher 21.0%+, while the SPY lost -2.0%+ on the close.


Out of 41 occurrences since 1990, the SPY was always trading above the previous session’s close at least once during the then following regular session, but had its difficulties to penetrate its previous session’s high (it managed a higher high on only 2 occurrences). In addition, it penetrated its previous session’s low on every 3 out of 4 occurrences, both significantly worse than the market’s at-any-time chance to post a higher high and a higher low.

Conclusion(s): Should this sell off actually persist into the close (and leaving any news out of consideration), a (significantly) lower open on Thursday, November 10, or any follow-through of today’s weakness on tomorrow’s GLOBEX session might provide a favorable buying opportunity, targeting an exit price at or above today’s close.

Successful trading,
