On CAPS, 22% of the 37 All-Star members who have rated Synta believe the stock will underperform the S&P 500 going forward.

Just yesterday, one of those Fools, zzlangerhans, touched on the stock's seemingly unsustainable valuation:

Too much too soon for Synta, a stock enjoying the 2013 biopharma rocket effect. Ganetespib has proven very little so far, and certainly not enough to justify a [$650M] market cap. Management has been taking full advantage of the precipitous increase in stock value with dilutive financings to ensure that their salaries will be around for years even of ganetespib fails miserably. We shouldn't have much longer to wait with topline PFS and OS data from the phase II portion of the GALAXY trial of ganetespib in advanced NSCLC expected later this year. I'm expecting a heavy emphasis on subset analyses.
