Quote from Brandonf:
The bigger the gap, statistically speaking, the less likely it is to fill in.
The "common wisdom" that of "all gaps fill" is nearly always true with small and regular size gaps, I think the data I had showed that small gaps fill about 91% of the time and that regular gaps fill about 70 something percent of the time (of course that doesnt mean they don't go $5.00 againt you first before a 10 cent gap is finally filled)
However, when you start to deal witih gaps that are more then twice as big as the average gap they rarely are filled, at least going out 10 days (which is the furthest I took my data out), I think the number was in the upper 60ish%'s on them not filling.
This particular chart pattern you are dealing with would also have me miles away from shorting it right now because it's actually coming off of a pretty powerful bottom formation, and the large gap just provides more fuel to that fire. Your probably looking at 20/30% more upside before you see a significant pullback in my opinion.
I pretty much developed an entire strategy from that study of going with the flow on big gaps and during the last year and a half that I was trading very actively it was by far the most profitable strategy I had.
So this isnt to say the XLF won't fill...my exwife ran over my crystal ball and so it's not working..but the statistics dont stand in your favor on it.
