Last week’s IPO opening-day performances read like a book. All you needed to know on how well or how poorly your favorite IPO will trade is found on the cover of its final prospectus. But nobody gives you anything on Wall Street – you have to do your own work.

Check the final pricing terms of your favorite IPO with the most recent filing found in its preliminary prospectus. Following this advice would tell you all you needed to know about last week’s market.

The IPO calendar produced five deals – one priced above its latest filing terms, two within and two below.

Not surprisingly, one popped, two struggled and the other two flopped.

The Pop

J.P. Morgan and Deutsche Bank Securities priced 5 million shares at $18 each, UP from its most recent filing range of $14 to $16 per share. The IPO started trading on Wednesday morning at $23, closed its opening day at $24, and ended on Friday at $28.40 — UP 57.8 percent from its initial offering price.
