Covidien (COV - option chain) shares are rising today after the company said last night said it expects sales to grow between 6 and 9 percent in 2011, in line with and slightly on the higher side of analysts' forecasts of 7 percent growth. 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 COV.

COV opened this morning at $39.27. So far today the stock has hit a low of $39.02 and a high of $39.90. As of 12:20, COV is trading at $39.46 up $1.56 (4.1%). The chart for COV looks bullish and S&P gives COV a positive 4 STARS (out of 5) buy ranking.

Option traders appear to be setting up for a bullish move on Cypress Bioscience, Inc. (CYPB). Traders plowed into 1,305 new call option contracts -- 19.19 times the average volume -- on the stock on Friday. And we know that traders were eager to get into this trade because 100% of the trades came in on the ask price.

Cypress has been in a downtrend since hitting a high around $10.00 in July 2009. The stock closed Friday at $3.39, down 10.79% during the past month.

Somanetics (SMTS) was the most advancing stock in the Nasdaq Wednesday morning, with shares up more than 31%, or nearly $6 to $24.85. Shares reacted to news that Covidien (COV) is buying Somanetics, acquiring all of the outstanding shares of Somanetics for $25.00 per share in cash, a 32% premium to Tuesday's close. Covidien will pay a total of $250 million, for a total transaction value of approximately $300 million.

Covidien, a drug and medical devices maker, is already the distributor for Somanetics' noninvasive diagnostic equipment called INVOS (In-Vivo Optical Spectroscopy) Cerebral/Somatic Oximeter in Europe, the Middle East and Africa. INVOS monitors patients and continuously measures blood oxygen levels in the brain and in the body to help detect and correct complications.

It's now or never, as far as realizing an outsized gain with medical device supplier Covidien Plc (COV), which is why I'm reiterating my buy rating for the company's share's, first recommended on June 4, 2009 at a price of $35.65. If you bought COV in June, you're up about 35%.

Further, the investment calculation with Covidien isn't rocket science: an aging U.S. population and the likelihood that U.S. public policy will universalize health care means that roughly 3-5 million more citizens per year for the next 8-10 years will receive regular health care services. And that means one thing: it's a good time to be a medical supplier (or a nurse, or radiologist, or surgeon, etc.).
