Analyst downgrades:

Allergan Inc. (NYSE: AGN) opened at $123.64. So far today the stock has hit a low of $123.40 and a high of $124.42. As of 12:20, AGN is trading at $124.09, up $0.45 (0.4%).

After a dip that began in late 2006, this stock found support in March and rebounded nicely, climbing to a new all-time high today. Jim Cramer called the Botox maker the "single best baby boomer play there is," shaking off concern that Medicis (NYSE: MRX) will come up with a cheap alternative that will hurt the Botox biz. Cramer believes Allergan's market is strong and will keep the stock going higher. Recent technical indicators for AGN have been bullish and steady, while S&P gives the stock a positive 4 STARS (out of 5) buy rating.

For a bullish hedged play on this stock, I would consider an October bull-put credit spread below the $105 range. AGN hasn't been below $105 since July and has shown support around $117 recently. This trade could be risky if one of the company's products gets in trouble with the FDA, but even if that happens, this position could be protected by the strong historical support around $106.
