One other thing, the end of this month has a, what I consider to be, very statistically significant meaning in "the spreadsheets" on OAS vs. enrolled population characteristics.
Not sure if you've been following, but if anybody else has come close in their spreadsheets to this understanding then June 28th or so will be a double positive - kind of a study milestone as well as Russell listing.
The stock price action does not follow the significance of the calendar well. Sort of, but not really well. (so far)
Basically we go past the most conservative treatments of statistics on the 10% OAS issue including dropouts and it suggests that 10% is very probably low on the degree of effectiveness.
