SunPower (NASDAQ: SPWR - option chain) shares are soaring higher today after Pacific Gas and Electric Co. said it has chosen SPWR to supply up to 800 megawatts of renewable energy. On the news, an analyst at Merrill Lynch also upgraded SPWR to "Buy" from "Hold." If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on SPWR.

SPWR opened this morning at $87.64. So far today the stock has hit a low of $87.57 and a high of $93.93. As of 12:55, SPWR is trading at $93.26, up $14.69 (18.7%). The chart for SPWR looks neutral and S&P gives SPWR a 3 STARS (out of 5) hold ranking.

For a bullish hedged play on this stock, I would consider a December bull-put credit spread below the $55 range. A bull-put credit spread is an options position that combines the purchase and sale of put options to hedge risk in case the stock doesn't do what you think, but willstill leverage nice returns. For this particular trade, we will make an 11.1% return in just four months as long as SPWR is above $55 at December expiration. Sunpower would have to fall by more than 40% before we would start to lose money. Learn more about this type of trade here.

SPWR hasn't been below $55 since March and has shown support around $71 recently. With the way the political climate is shaping up, it looks like some form of solar power should be here for quite a while.

If you are a true stock fanatic (like me), your question about every investment is a take-off on the sin-avoidance question asked by Christians everywhere: WWBB? What would Buffett buy?

If investing is a religion, Warren Buffett is prophet, high priest, saint and lesser diety, all rolled into one. The way he goes, so goes the world's best and brightest (and for good reason. He's smart). The big news on everyone's lips, today, is that Buffett is once again in the market for some juicy acquisition; perhaps in the energy sector. Here are some leading suggestions:

• PG&E, San Francisco's utility. Worth $13 billion, this company is seen as a solid local utility that successfully weathered the energy crisis of the last several years. The stock is up $1.29 today to $40.75 on the rumors.
  
• Mercury General Corp., Los Angeles-based automotive insurer. Worth $3 billion, the company has a 16% ROE and a low debt balance. Warren Buffett loves his insurance companies, and the company's stock is up $2.35 to $57.90 in intraday trading on the speculation.
  
• Les Schwab Tires, a Prineville, Oregon-based tire store chain. Founder Les Schwab has retreated following the recent death of his daughter, and the company fits into Buffett's love for innovative and well-run companies.
