Each buy is entered on the first trading day after it was filed. One observation counts per stock and entry day. A t statistic near 0 means the average is indistinguishable from luck; above about 2 or below about -2 it is unlikely to be chance.

A return curve needs at least 10 scored buys. Richard Blumenthal does not have enough yet.
