Mind the gap! How long do you have to wait for an SPX gap to fill? The average is 33 bus days, but the distribution is very skewed. 50% of gaps filled in 7 bus days. 75% of gaps filled in 35 days. 9% of gaps currently unfilled. Data from March 29, beginning of official bull market.Historically gaps filled been to be a tailwind for SPX. 7 business day future return after the gap has been filled is c0.8% compared to c0.35% all 7 business days returns in SPX.
Suggests statistical significance at >99%
