Did your mutual fund make big money yesterday?

No, Thursday's rally was a counter-rally, sending up a lot of stuff that had lagged. The big winners for the year, the oils, the oil-service companies, the real estate companies, the health care cost-containment companies and the best retailers -- where the real action is and where the gains for the second half will be -- all were

Go for them.
