Stock prices/stock valuation models are linked to the risk free rate, which is increasing, so the value of all stocks, in theory declines when rates are higher. I think much of today's selling/decline is coming from either EFT's or program trading, nothing to do with IMGN's value. We should know more about 2Q sales in early July, that's what will drive the stock price, other than the market. It looked to me like there was good demand in the low $16 range and the technicals were oversold and starting to round upward. Unless the market decline is severe, I expect IMGN will return to $16+ fairly soon. All IMO, not advice.
