Lumber Liquidators Holdings Inc (NYSE:LL) (MarketWatch)
Shares of Lumber Liquidators Holdings Inc. LL, -9.16% slumped 2.6% in premarket trade Monday, after the wood floorings seller was downgraded at Wedbush, citing concerns the company’s fourth-quarter results will miss expectations because of accelerating promotions and increased competition. Analyst Seth Basham cut his rating to neutral, after being at outperform the past nine months. He slashed his stock price target to $28 from $39.

Alexion Pharmaceuticals, Inc. (NASDAQ:ALXN) (Seeking Alpha)
A Phase 2 clinical trial assessing Ra Pharmaceuticals’ (RARX +2.4%) subcutaneously administered RA101495 in patients with paroxysmal nocturnal hemoglobinuria (PNH) showed a positive effect in patients who were naive to Alexion Therapeutics’ (ALXN +5.3%) Soliris (eculizumab). The data weren’t so good for patients on Soliris therapy, however. In 10 PNH patients naive to Soliris, treatment with RA101495 met the primary endpoint of a sustained reduction in lactate dehydrogenase (LDH) levels from baseline to the mean of weeks 6 – 12 (p=0.002) with near-complete suppression of complement activity. Half (n=3/6) of the transfusion-dependent subjects prior to enrollment remained transfusion-free during the study period.
