Dear traders. Essentially what Dell did is sell your N shares at closing 111.17, then took the proceeds and bought N shares at opening of 55.59, plus bought 0.44 * N shares of VMW for you. It is a net sum zero gain. You did not lose any $. But As of 2 hours in today Dell is down 3% while VMW is up 6% so you made +3% on your Dell investment.
