Today's biggest winners and losers in the stock market.

On this episode of Stock Movers:

 - Dollar Tree (DLTR) shares rose after the retailer’s conference call comments eased investors concerns about the traffic decline in in the fourth quarter, as transaction size drove comparable sales growth.

- Electronic Arts (EA) stocks slightly spiked after news broke that Wall Street banks led by JPMorgan Chase & Co. have already attracted enough demand for the nearly $15 billion of debt it is selling to back the leveraged buyout of video game maker Electronic Arts Inc., the largest of its kind.

- Nvidia (NVDA) shares jumped today as executives will likely need to deliver a surprise at the chipmaker’s annual AI conference, that begins today, to spark a rally in the moribund stock. The four-day event, called GTC, comes after six months in which the shares have essentially treaded water amid concerns that Nvidia’s rapid revenue growth is peaking. Not even a banner earnings report last month was good enough to impress investors, as the shares fell 5.5% the following day.
