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

Stocks were boosted by Fed Chairman Ben Bernanke's Congressional testimony about the economy and monetary policy, but came off highs as he discussed when the Fed might start paring back on its bond buying program.

Nine of the ten large-cap S&P 500 sectors were in the green at midday. Health care was the best performer, while utilities dipped into the red.

General Electric was up after Dow Jones reported that its CEO Jeff Immelt said the U.S. economy gets "a little better every day."

OpenTable slid after the online reservation company released the results of its OpenTable Restaurant Industry Index that showed reservations in first quarter were down "slightly" year-over-year.

Catamaran was the worst performer on the Nasdaq after UBS noted cautious comments from management combined with its analysts' reduced expectations for a deal with Cigna.

Amphenol was lower after a downgrade to "hold" from "buy" at Stifel Nicolaus. The analyst cites valuation as reason for the downgrade.

Zale surged after reporting third-quarter earnings and comparable-store sales up 1.4 percent. The jewelry retailer also named former Kay Jewelers CEO Terry Burman as chairman of the board.

Monster Beverage was up after the stock was initiated at "outperform" at BMO Capital Markets with a price target of $65 per share. The BMO analyst says the stock is at a "compelling entry point" and notes "the incessant negative media coverage of the energy drinks category."
