In the printing services complex, insiders are loading up on a large amount of stock in VistaPrint ( VPRT), which operates as an online provider of marketing products and services to micro businesses worldwide. Insiders are buying into some solid strength here since the stock is up over 20% so far in 2012. VistaPrint has a market cap of $1.37 billion and an enterprise value of $1.41 billion. This stock trades at a reasonable valuation, with a trailing price-to-earnings of 20.32 and a forward price-to-earnings of 18.15. Its estimated growth rate for this year is -23%, and for next year it's pegged at 15.3%. This is not a cash-rich company, since the total cash position on its balance sheet is $67.47 million and its total debt is $146.50 million. After you back out the cash, VistaPrint has $79.03 million in debt on its books. A beneficial owner just bought 100,000 shares, or around $3.95 million worth of stock, at $38.67 per share. From a technical perspective, VPRT is currently trading below its 50-day moving average and above its 200-day moving average, which is neutral trendwise. This stock has been struggling during the past two months whenever it's traded above $40 a share. Each time it's traded over $40 the stock has run into sellers, and it's now started to make lower highs. Lower highs are a bearish technical pattern and it shows that sellers are dumping the stock into any strength. If you're bullish on VPRT, I would only look for long-biased trades once this stock breaks out above $38.05 and its 50-day moving average of $39.20 a share with high-volume. Look for volume on a move above those levels that hits near or well above its three-month average action of 513,258 shares. If we get that action soon, look for VPRT to run back into the $40s.I would only look for an extended up move if $41.92 was taken out with volume. Traders should avoid this stock entirely from the long side if VPRT drops back below its near-term support at $35.88 and then back below its 200-day moving average of $34.29 with volume. A high-volume move below those levels could set this stock up for some serious downside.
