With the Standard & Poor's Small-Cap 600 index at its highest level since last July, a lot of investors are looking closely at lesser-known companies. Time will tell whether this is a quarterly aberration or whether smaller stocks, which have lagged blue chips in recent years, are in for an extended run. But for investors interested in researching smaller stocks, The Times asked Zacks Investment Research to screen its database of stocks below $1 billion in market capitalization and cull the top 10 based on three equally weighted criteria: the percentage change in earnings-per-share estimate for the current fiscal year, the change for the next fiscal year and the increase in insider stock holdings--all during the last 12 weeks. Some of these are slumping companies that recently posted losses, but analysts and company insiders seem to be saying, "That was then, this is now." As with all screens, this list should be used as a tool for further research and not taken on its own as a recommendation to buy any of the stocks.
