On CAPS, 8% of the 663 All-Stars who have rated Geron believe the stock will underperform the S&P 500 going forward.

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

Geron Corp has doubled from it's June lows. ... A less toxic chemo drug delivery system seems promising, but also seems difficult to correlate and time consuming to study. ... Cash burn rate and cash position seem relatively strong although many biopharms sell into strength anyway. This might have made a good speculative up-play at $1.30 as insiders did. Overall, I'm not supporting the market cap at this stage.
