Net Perceptions shares stormed up 3 1/4, or 32 percent, to 13 1/2 Monday after Piper Jaffray reiterated its "strong buy" recommendation on the Internet software developer.
In a radio interview Monday, Nada said he based his upgrade on the fact that going into Monday, Net Perceptions (Nasdaq: NETP) was trading at just 10 times estimated 2002 earnings, or even less discounted back to today's dollars.
Net Perceptions shares fell to a 52-week low of 9 3/4 last week after peaking at 66 1/2 in January.
First Call consensus expects it to post a loss of 20 cents a share in its first quarter, up from the 14 cents a share it lost last quarter.
Last week, Adams Harkness bumped the stock from a "trading buy" recommendation to a "strong buy."
