Maybe I'm missing something obvious but I don't understand how some stock prices are moving. For example, as I write this 7 Days in Utopia ipo'd yesterday at $7 and there are 16M shares short and 1.6M long and the stock is UP $1.14! Today's volume is approx. 6M short to 1M long. How the heck can a stock move up so much with such a short to long discrepancy? I've seen it in a number of stocks going opposite the way than would be expected with large differences in shorts to longs or vice versa. Could someone explain it to me please? Thanks.
