RE: Big dump today...any ideas why? Panoramic shares are plummeting in value, and you wont get them in your account for a while. In the meantime everyone is shorting Panoramic. The best play is not to buy Magma but to short Panoramic. Its a stock deal which is lousy for MMW holders, the aquirer falls in value leading up to the transaction. Be very careful not to value this as if it were a cash deal or you could get burned badly after only a couple more down days for Panoramic.
