Investors apparently were happy with Winnebago’s order volume during the RV industry’s National Trade Show, because the motorhome manufacturer’s stock soared $3.74, or 12.5%, Friday (Nov. 30) to close at a new 52-week high of $33.70.

The trade show in Louisville ended Thursday (Nov. 29).

Winnebago did not issue any statements Friday to explain the sharp stock price increase.

Meanwhile, manufactured home and towable RV builder Skyline also saw its stock climb $2 a share, or 7%, Friday to close at a new 52-week high of $30.40.

Despite the fact the broader stock market closed essentially flat on Friday, most RV company shares increased in value. Among them was Fleetwood, which gained 55 cents, or 4.6%, to close at $12.55.

Thor, which reached a new 52-week high of $38.20 on Wednesday (Nov. 28), closed unchanged Friday at $38.
