Netezza surprised the Street last week, when it reported Q3 EPS of four cents and revenues of $33.4 million. Analysts had been expecting breakeven earnings and revenues of $29.4 million. The company had no outstanding debt at the end of the quarter. Management also guided FY08 revenues to about $120 million ($115.37M consensus) and FY09 revenues to about $160 million ($149.53M consensus). Needham subsequently reiterated its "buy" rating on the issue and boosted its price target to $19. NZ shares popped on the news and then moved into the initial stage of a bullish "pennant" consolidation pattern. Prices frequently exit pennants moving in the same direction they were traveling on entry. In this case, that would be to the upside.
