On CAPS, 97% of the 493 members who have rated ON believe the stock will outperform the S&P 500 going forward. These bulls include EPS100Momentum and All-Star IBDvalueinvestin, who is ranked in the top 5% of our community.

Late last month, EPS100Momentum explained why Fools need to hop onto ON: "Earnings will keep getting stronger as auto sector recovery keeps getting stronger and base at a higher level."

ON's focus on power consumption reducing-chips continue to make it a highly rated play on a rebounding auto market. Currently, the stock even trades at a forward P/E (8.8) discount to rival mid-caps STMicro (10.4), Fairchild (9.2), and National Semi (NYSE: NSM) (9.9), as well as much larger foes likes Texas Instruments (12.0) and Taiwan Semiconductor (NYSE: TSM) (11.6).

If an uptrend in auto sales is as good of a bet as CAPS member IBDvalueinvestin believes, that valuation gap should only close over time:

[ON is] a Poster Child for a company that will benefit greatly as the Automotive sector starts gaining traction again, its not a maybe it gains traction, its a definite.

3 years since crash started in Automotive sector, those that waited to buy a new car are pushing their luck and will have to start spending in 2011 , I was one of those holding off but eventually had to buy a new car this year, I was forced to do so by getting into a car accident with my oldie but goodie Infinity. So eventually your forced to buy a new car, either by an auto accident or a costly breakdown in your old car not worth fixing.
