Stocks to Watch: YELP, JOY, WLP & More

Take a look at some of Wednesday's midday movers:


Yelp surged as its 180-day “lockup” period ended. The stock price of the online business-review website had been selling off in recent sessions in anticipation of more shares hitting the market but, the action today is to the upside on heavy volume. Yelp started trading on Mar. 2 at $15 per share.

Joy Global plunged after the mining-equipment maker cut its earnings forecast for fiscal year 2012. The company said it sees slowing growth in China and Europe hurting demand for coal.

Jos. A. Bank jumped following better-than-expected results for its second-quarter earnings. Sales climbed 12.9 percent helped by strong online sales.

Retailers TJX Companies and Chico’s FAS were also higher, both stocks at 52-week highs ahead of same-store sales reports expected Thursday.

Wellpoint surged after the health-insurance company's CEO Angela Braly announced that she will be stepping down.

Devon Energy traded lower. The company announced that its management will present at the Barclays Capital CEO Energy-Power Conference in New York on Sept. 6.
