| Construction: |

The
portfolios, which are constructed monthly, are the intersections of 2
portfolios formed on size (market equity, ME) and 3 portfolios formed on prior
(13-60) return. The monthly size breakpoint is the median NYSE market equity.
The monthly prior (13-60) return breakpoints are 30th and 70th
NYSE percentiles. |

The
six portfolios constructed each month include NYSE, AMEX, and NASDAQ stocks
with prior return data. To be included in a portfolio for month t (formed at
the end of the month t-1), a stock must have a price for the end of month t-61
and a good return for t-13. In addition, any missing returns from t-60 to t-14
must be -99.0, CRSP's code for a missing price. Each included stock also must
have ME for the end of t-1. |
