Today's biggest winners and losers in the stock market.

On this episode of Stock Movers, we take a look at some of the week's biggest gainers and decliners:

- JB Hunt (JBH) led trucking stocks lower on Wednesday after the company warned that higher costs for fuel and recruiting will hurt its earnings.

Shares of the US maker of backup power generators surged as much as 32% on Thursday, the biggest intraday increase in more than 14 years. It was the stock's best week since May.

- Cryptocurrencies rallies on Friday amid stronger appetite for risk assets, as investors looked past the failure of a landmark US crypto bill and the Fed's first interest-rate increase in more than three years.
