Ruckus Wireless (RKUS) came public today at $15 a share, the top of its projected $13 to $15 range. That turned out to be the high of the day; the investment syndicate wouldn't even support the stock for 30 seconds. Even the Facebook syndicate at least supported the price at IPO levels for one day. But not this group. By the end of the day, the stock had fallen by a sickening 18.3% to close at the lows of $12.25. Welcome to Wall Street, IPO investors.
