OmniVision (OVTI - option chain) stock is trading sharply lower today after Sony (SNE) CEO Howard Stringer said late Friday that his company is supplying camera components to Apple (AAPL). This could pose a threat to OVTI's AAPL business, as OVTI had been the main supplier of image sensors for the iPhone. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on OVTI.

This morning, OVTI opened at $34.06. So far today the stock has hit a high of $34.10 and a low of $32.20. As of 12:15, OVTI is trading at $33.15, down $3.04 (-8.4%). The chart for OVTI looks neutral and S&P gives OVTI a neutral 3 STARS (out of 5) hold ranking.
