For reasons enumerated in today’s issue of Smart Tech 50 Weekly Movers, today we are closing out our short sell recommendation in 3D Systems (NSDQ: DDD). Back in January we featured it as our best short sale idea when it rose above $90, and now that it is below $60 we think it is time to take our profits and look elsewhere.  And even if you shorted it at $80 when we first added it to our Equity Trades portfolio in December, we will gladly book at 30% profit in just three months (however, if you choose to leave your position open please be advised that the stock has substantial price support at $50, which is only 15% below where it is trading today so there is not a lot of “upside” potential left in this trade). This is our first “round-trip” portfolio recommendation since we launched STI 100 days ago, and we are proud to have the first one work out to annualized gain in excess of 100%!
