Another stock to consider with some decent insider buying is Tenet Healthcare ( THC), an investor-owned health care services company whose subsidiaries and affiliates own and operate acute care hospitals, ambulatory surgery centers, diagnostic imaging centers and related health care facilities. Insiders are buying this stock into some decent strength, since shares are up around 18% so far in 2012. Tenet Healthcare has a market cap of $2.54 billion and an enterprise value of $7.21 billion. This stock trades at reasonable valuation, with a forward price-to-earnings of 9.24. Its estimated growth rate for this year is 54.1%, and for next year it's pegged at 15.8%. This is not a cash-rich company, since the total cash position on its balance sheet is $82 million and its total debt is a whopping $4.75 billion. A beneficial owner just bought 3 million shares, or around $17.25 million worth of stock, at $5.75 per share. From a technical perspective, THC is currently trading above both its 50-day and 200-day moving averages, which is bullish. This stock recently triggered a big breakout after it cleared some near-term overhead resistance levels at $5.35 to $5.64 a share with heavy upside volume. Following that breakout, THC went on to hit a recent high of $6.44 a share. The stock has since then cooled off a bit and trended down towards $6 a share. If you're bullish on THC, then I would look for long-biased trades once it manages to break out above some near-term overhead resistance levels at $6.44 a share with high volume. Look for a sustained move or close above $6.44 with volume that tracks in close to or above its three-month average action of 7,891,600 shares. If that breakout triggers soon, then look for THC to re-test or possibly take out its next major overhead resistance level at $7.70 a share. One can look to buy THC off any weakness to anticipate that breakout and simply use a stop that sits around $5.60 to $5.40 a share.
