Shares in Ihop Corp. dipped more than 10 percent Wednesday after a poor second quarter earnings report from Darden Restaurants Inc. led Wall Street analysts to sour on the casual dinning sector.

Shares in Darden, which operates several chains including Olive Garden and Red Lobster, lost nearly 22 percent. Ruby Tuesday’s Inc., P.F. Chang’s China Bistro Inc. and Ruth’s Chris Steak House Inc. all hit new 52-week lows during trading Wednesday.

The declines followed Darden’s second quarter earnings release late Tuesday, in which the casual dining operator reported a 30 percent profit decline.

Bear Stearns analyst Joseph Buckley added to the concern when he said in a research report that the earnings report from Darden’s shows that earnings “confirm our concerns that current-quarter results for the casual dining sector are very likely to be disappointing.”

Shares in Ihop were down $4.38, or 10 percent, to $38.36 in early trading Wednesday on the New York Stock Exchange. Shares hit a new 52-week low of $38.47 during trading.
