One electrical alternative vehicle maker that insiders are snapping up a huge amount of stock in is Tesla Motors ( TSLA), which designs, develops, manufactures and sells high-performance fully electric vehicles and advanced electric vehicle powertrain components. Insiders are buying this stock into some monster strength, since shares are up 169% so far in 2013. Tesla Motors has a market cap of $10.6 billion and an enterprise value of $11.5 billion. This stock trades at a premium valuation, with a forward price-to-earnings of 87.35. Its estimated growth rate for the next quarter is 102.2%, and for this year it's pegged at 101.2%. This is not a cash-rich company, since the total cash position on its balance sheet is $214.24 million and its total debt is $455.54 million. >>5 Rocket Stocks to Buy in June The CEO just bought 1,084,129 shares, or about $100 million worth of stock, at $92.24 per share. From a technical perspective, TSLA is currently trending above both its 50-day and 200-day moving averages, which is bullish. This stock has been downtrending since hitting its all-time high at $114.90 a share last week. During that move, shares of TSLA have been mostly making lower highs and lower lows, which is bearish technical price action. Shares of TSLA are now trading just above some key near-term support levels at $88.25 to $85.28 a share. If you're bullish on TSLA, then look for long-biased trades as long as this stock is trending above either $88.25 or $85.28 and then once it breaks out above some near-term overhead resistance levels at $96.42 to $100 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 7.29 million shares. If that breakout triggers soon, then TSLA will set up to re-test or possibly take out its next major overhead resistance levels at $110 to its all-time high at $114.90 a share. Keep in mind that a break below those key support levels at $88.25 to $85.28 a share with volume will then set shares of TSLA up to drop back towards its next major support levels at $78.11 to $70 a share. This stock has made a parabolic move over the last few months, so going long should only be done if we see high-volume strength above those key near-term support levels.
