Is This Move About Axsome Therapeutics Or The Market?
The market explains little of this: the S&P 500 gained 1.3% over the same 9 sessions, including dividends, against Axsome Therapeutics’ -11.8%. Over the past three months the stock is down 30.5%, a window that includes the streak; over the other 54 sessions of that window it was down 21.3%.
Do The Fundamentals Justify The Selling?
On the fundamentals, revenue grew 56.9% over the last twelve months, against a median of 8.1% for S&P 500 Health Care stocks; and its operating margin is -23.5%, versus a median of 17.6%. Axsome Therapeutics does not have positive trailing earnings, so there is no meaningful price-to-earnings multiple to compare. The fundamentals give the sellers some support: an operating loss.
