A couple Buy ratings to tell you about this morning.  Deutsche Bank has upgraded American Superconductor (AMSC) to Buy and raised the price target $38. Hat tip to Street Insider for the following analyst comment:

“On fears of slowing demand for wind power in China, AMSC’s shares have underperformed the R2000 by 39% YTD. We expect this to reverse over the next 6 months following bullish FY10 guidance (in mid May), new wins (including follow-on with Sinovel) and moderating losses in superconductors.

Shares of AMSC have gapped up about 5% on the upgrade and appear to be on the verge of breaking out of its downtrend that began in January.  This upgrade may be what’s needed to begin the right side of a new base.  Get additional AMSC analysis here.

GT Solar International (SOLR) is also getting a Buy rating. Wunderlich Securities has initiated coverage with a Buy and price target of $8.

Shares of SOLR gapped up nearly 10% this morning before pulling back a bit.  It too is now trading above key resistance of the 50 and 200 day moving averages.  Get additional SOLR analysis here.
