One more stock whose insiders are doing some large buying is Keynote Systems ( KEYN), a global provider of Internet and mobile cloud monitoring and testing solutions. Insiders are finding some value here since this stock is down by 23% so far in 2012. Keynote Systems has a market cap of $275 million and an enterprise value of $223 million. This stock trades at a cheap valuation, with a trailing price-to-earnings of 6.02 and a forward price-to-earnings of 12.91. Its estimated growth rate for this year is -16.1%, and for next year it's pegged at 23.20%. This is a cash-rich company, since the total cash position on its balance sheet is $43.63 million and its total debt is zero. A beneficial owner just bought 595,600 shares, or about $9.09 million worth of stock, at $15.00 per share. From a technical perspective, KEYN is currently trading below both its 50-day and 200-day moving averages, which is bearish. This stock recently sold off hard from near $19 to a low of $14.77 a share. Following that selloff, this stock has started to find some buying interest with the stock trading up 3.2% on Wednesday to $15.75 a share in weak overall market. If you're bullish on KEYN, I would only look for long-biased trades if this stock can manage to trigger a near-term breakout above $16 a share with high-volume. Look for volume on that move that's near or well above its three-month average action of 131,089 shares. If we get that move soon, look for KEYN to make a run at its 50-day moving average of $18.53 a share or possibly into the low $20s. Traders should avoid KEYN or look for short-biased trades if this stock fails to get back above $16, and then drops below some near-term support at $14.77 a share with high-volume. A high-volume move below $14.77 will mean KEYN is printing a new 52-week low and is most likely heading much lower to possibly $12 a share.
