One more stock to consider with some decent insider buying is Entegris ( ENTG), a developer, manufacturer and supplier of products and materials used in processing and manufacturing in the semiconductor and other technology industries. Insiders are buying this stock into some modest weakness, since shares are off by 5% so far in 2012. Entegris has a market cap of $1.14 billion and an enterprise value of $813.11 million. This stock trades at a cheap valuation, with a trailing price-to-earnings of 11.61 and a forward price-to-earnings of 12.86. Its estimated growth rate for this year is -28.8%, and for next year it's pegged at 12.3%. This is a cash-rich company, since the total cash position on its balance sheet is $315.83 million and its total debt is zero. A beneficial owner just bought 398,800 shares, or around $3.17 million worth of stock, at $7.83 to $8.02 per share. From a technical perspective, ENTG is currently trending below both its 50-day and 200-day moving averages, which is bearish. This stock recently plunged from its high of $9.35 to a low of $7.50 a share with above-average volume flows. Following that plunge, shares of ENTG have started to rebound and uptrend from $7.50 to $8.36 a share. That rebound has now pushed ENTG within range of triggering a near-term breakout trade. If you're bullish on ENTG, then I would look for long-biased once this stock manages to break out above some near-term overhead resistance levels at $8.46 to $8.61 a share with high volume. Look for a sustained move or close above those levels with volume that hits near or above its three-month average action of 598,391 shares. If ENTG triggers that breakout soon, then look for this stock to set up to re-test or possibly take out its next major overhead resistance levels at $9.35 to $10.18 a share. Any high-volume move above those levels will then put $10.58 into focus for ENTG.
