I was looking over some of the stocks mentioned in our Analyst Calls piece. Footwear concern Wolverine World Wide (WWW) was initiated with a buy rating courtesy of KeyBanc. Is buying this stock the right thing to do?

At the time of this writing, shares of the company were up fractionally to $36.53. That isn't far off from the 52-week high of $37.52. Volume of shares traded today, however, isn't impressive.

As the new earnings season kicked off, Alcoa Inc. (NYSE: AA) posted better-than expected results, despite a decline in earnings, and Pepsi Bottling Group (NYSE: PBG) topped Wall Street expectations as well. This just goes to show that there is some good news in earnings if you know where to look. Here are a few recent, less-prominent examples.

Flow International Corp. (NASDAQ: FLOW), which makes industrial waterjet equipment, swung to a better-than-expected fiscal fourth-quarter profit of $13.3 million, or 35 cents per share, helped by a boost in sales due to strong demand and an income tax benefit. Revenue rose 21% to $63.3 million. Shares are creeping up from a 52-week low of $6.81 a week ago.

Motor sports company International Speedway Corp.'s (NASDAQ: ISCA) second-quarter profit rose 41% to $26 million, or 52 cents per share. However, revenue slipped 3% to $174.9 million as admission and food and merchandise sales declined. Results fell short of Wall Street expectations, and shares fell to a 52-week low of $36.36.

Apparel and footwear company Wolverine World Wide Inc. (NYSE: WWW), second-quarter profit of $16.8 million, or 33 cents per share, topped Wall Street expectations, as strong international results linked to the weaker dollar largely offset increased product and freight costs. Revenue climbed 7% to $267.4 million. But shares fell $3.11 to $23.46 in morning trading.

Here are some highlights from this past week's earnings coverage from BloggingStocks:

Wolverine World Wide, Inc. (NYSE: WWW), a footwear maker that competes with businesses such as The Timberland Company (NYSE: TBL), announced impressive earnings -- yet the stock as of this writing was down almost 3%. What gives, you ask? Well, it looks like revenues came in a bit on the light side.

According to Briefing.com, Wolverine beat Wall Street's expectations by a whopping three pennies. They came in at $0.46 per diluted share -- this represented growth over the previous year's quarter of almost 18%. But the top line was rather sheepish in terms of expansion -- Wolverine took in $288 million this quarter versus $281 million in Q1 2007. Yeah, that performance wasn't anything to be proud of, I suppose. So investors were in a punishing mood and sold the stock.

Still, Wolverine is an interesting stock that probably should be put on a watch list. It's not too far from the 52-week high, it doesn't appear to be overly expensive, and according to the company's earnings release, gross margins expanded by 100 basis points. I wouldn't necessarily get in now if I wanted to invest in Wolverine, but I'd be on the lookout for pullbacks.
