Advance Auto Parts (NYSE: AAP) has pulled-back about $4 since first recommended on May 19, 2009 at a price of $43.38, but view that as a Buy opportunity.

That's because an argument can be made that auto repair represents one of the best sectors over the next one-two years. Here's why:

Analyst upgrades:

• Janney Montgomery upgraded Aqua America (NYSE: WTR) to Buy from Neutral on valuation, viewing the recent weakness as a buying opportunity. The firm has a $19 target on the stock.
• UBS upgraded Gildan Activewear (NYSE: GIL) to Buy from Neutral due to customer Broder's improved liquidity and the improved outlook for margins.
• RBC Capital upgraded State Street (NYSE: STT) to Top Pick from Outperform and raised its target to $55 from $40. The analyst said the $2B capital raise addresses TCE ratio concerns and large unrealized losses in the investment portfolio.

• Advance Auto Parts (NYSE: AAP) was upgraded to Buy from Underperform at Banc of America/Merrill.

Advance Auto Parts (NYSE: AAP - option chain) shares are dropping today after the company forecast a third-quarter profit of 57 cents per share, coming in way below analysts' estimates of 66 cents per share. 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 AAP.

This morning, AAP opened at $31.96. So far today the stock has hit a low of $27.73 and a high of $32.78. As of 12:05, AAP is trading at $29.71, down $4.66 (-13.6%). The chart for AAP looks neutral and S&P gives AAP a 3 STARS (out of 5) hold ranking.

For a bearish hedged play on this stock, I would consider a December bear-call credit spread above the $40 range.
