One final name with some big insider buying is wealth management player Blackstone Mortgage Trust ( BXMT), which is a self-managed, real estate finance and investment management company that specializes in credit sensitive financial products. Insiders are buying this stock into strength, since shares are up around 50% so far in 2013. Blackstone Mortgage Trust has a market cap of $663 million and an enterprise value of $1.09 billion. This stock trades at a cheap valuation, with a trailing price-to-earnings of 1.86 and a forward price-to-earnings of 13.77. Its estimated growth rate for next year is pegged at 430.6%. This is not a cash-rich company, since the total cash position on its balance sheet is $66.29 million and its total debt is $481.95 million. A beneficial owner just bought 1,960,784 shares, or about $49.9 million worth of stock, at $25.50 per share. The CEO also just bought 19,608 shares, or about $500,000 worth of stock, at $25.50 per share. From a technical perspective, BXMT is currently trending above both its 50-day and 200-day moving averages, which is bullish. This stock has been downtrending modestly for the past few weeks, with shares moving lower from its recent high of $29.29 to its intraday low of $25.98 a share. During that move, shares of BXMT have been consistently making lower highs and lower lows, which is bearish technical price action. That said, shares of BXMT have so far been able to find some buying interest right around its 50-day at $26.09 a share. If you're bullish on BXMT, then look for long-biased trades as long as this stock is trending above its 50-day at $26.09 or above some more key support at $25.63, and then once it breaks out above some near-term overhead resistance levels $29.28 to $29.50 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 271,073 shares. If that breakout triggers soon, then BXMT will take out its double top resistance zone at $29.29 to $29.50 a share, which is bullish price action. Some possible upside targets off that breakout are $33 to $35 a share.
