Wednesday on Mad Money, Cramer discussed another stock that recently moved to the Mid Cap 400. I didn't write down the name as I'm fully invested, but he was recommending the stock as a buy. He said that the last 19 stocks which moved into the S&P 400 were up about 36% overall (16 stocks up, 3 down.) He said that Mid Caps were the place to be for investors because that's where the growth is. Apparently the announcement about MRX came after the show's taping, but MRX moving into the Mid Cap 400 is great news.
