A lackluster week for American IPOs is ending with a flop, as Metals USA (MUSA) is down 6% from last night's $21 pricing. Computer storage company Nexsan shelved its IPO today after struggling to price, and regenerative-organ replacement company Tengion (TNGN) cut its price to $5 from a planned $8-10 range.
