So what: Winnebago shares came into the month with momentum, having gained 13% in February since the stock hit bottom on Feb. 9. There was little news out on the company through the first half of March, but the stock continued to move higher as it seemed be oversold during the previous sell-off, trading at a P/E of just 10 at one point. Like many stocks, Winnebago's swings tend to be more exaggerated than the broader market's, due to the nature of its business selling expensive recreational vehicles.
