Tuesday's Winners & Losers: Ruth's Chris

Shares of ABM Industries(ABM Quote) were among the NYSE's winners Tuesday, rising 4% after the facility services company posted better-than-expected first-quarter earnings.

The company earned $8.7 million, or 18 cents a share, on revenue of $703.5 million. The results included a 1-cent gain related to a reversal of the company's self-insurance reserves. That was partially offset by stock-based compensation costs and a litigation-related contingent loss provision. Analysts polled by Thomson First Call expected earnings of 15 cents a share. A year earlier, ABM earned $4 million, or 8 cents a share, on revenue of $666.6 million.

Looking ahead, ABM forecast second-quarter earnings of 28 cents to 32 cents a share. The guidance includes a pretax gain of about $5 million and a charge of $1.9 million. Analysts, on average, project earnings of 24 cents a share. The stock was up $1.07 to $26.99.

Ruth's Chris(RUTH Quote) rose 7% after Standard & Poor's said it will add the steakhouse operator to its S&P SmallCap 600 index at the close of Wednesday's trading. The company will replace lender New Century Financial(NEW Quote), whose shares have plunged amid the ongoing problems in the subprime sector. New Century is no longer eligible for the index because of its market capitalization. Shares of Ruth's Chris were trading up $1.34 to $21.68.
