Father's Day is a special occasion for many of us, a day to show our daddies how much we love them. We give dad some extra attention that day and usually also a present that could make him happy. Kiplinger.com has an interesting idea -- one that I really like -- for a Father's Day present you may want to consider: Find a good stock that could bring him a lot of money.

Let's look at some of the companies Kiplinger's Anne Kates Smith believes would be good options this year:

• O'Reilly Automotive (NASDAQ: ORLY) is an auto parts retailer that is facing weak demand as a result of soaring crude oil prices. However, analysts believe the company's strategy to buy CSK Auto will bring a lot of national success. ORLY is expected to show earnings of $1.76 per share this year and $2.02 next year.
• Stanley Works (NYSE: SWK), headquartered in New Britain, Conn., has the advantage of being one of only two companies offering a complete line of hand tools for consumers. The company focuses its performance on both its industrial tool division and a security business. Analysts forecast a profit of $4.18 this year, and $4.63 a share for next year.

MOST NOTEWORTHY: O'Reilly Automotive, Corning and Lincoln National were today's noteworthy downgrades:

• William Blair downgraded O'Reilly Automotive (NASDAQ: ORLY) to Market Perform from Outperform following weak Q1 results, citing the potential for further downward EPS revisions.
  
• Thomas Weisel downgraded Corning Inc. (NYSE: GLW) to Market Weight from Overweight citing balanced risk/reward given the backdrop of a maturing LCD penetration and generational upgrade cycle, and the challenging environment.
  
• Wachovia downgraded Lincoln National Corp. (NYSE: LNC) to Market Perform from Outperform as they believe the weak Q1 market weakness will impact profitability.

OTHER DOWNGRADES:

• Smith International (NYSE: SII) was cut to Perform from Outperform at Oppenheimer.
  
• Delphi Financial (NYSE: DFG) was downgraded at Friedman Billings to Market Perform from Outperform.
  
• CIBC downgraded Biovail (NYSE: BVF) to Sector Performer from Sector Outperformer.

O'Reilly Automotive Inc. (NASDAQ: ORLY) shares are trading higher today the company said it will acquire CSK Auto Corp. (NYSE: CAO) for $500 million in a cash and stock deal. The combined company will be the third-largest U.S. auto parts retailer. If you think that the company 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 ORLY.

After hitting a one-year high of $38.84 last April, the stock hit a one-year low of $24.08 in January. ORLY opened this morning at $29.45. So far today the stock has hit a low of $29.18 and a high of $30.50. As of 12:20, ORLY is trading at $29.94, up $1.42 (5.0%). The chart for ORLY looks bullish and steady, while S&P gives the stock a neutral 3 Stars (out of 5) Hold rating.

For a bullish hedged play on this stock, I would consider an August bull-put credit spread below the $25 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 still leverage nice returns. For this particular trade, we will make an 8.7% return in just 5 months as long as ORLY is above $25 at August expiration. O'Reilly would have to fall by more than 16% before we would start to lose money. Learn more about this type of trade here.
