NEW YORK —  Shares of Best Buy rose 16 percent Thursday after it announced plans to create store-within-store kiosks for Samsung products – a vote of confidence from a major consumer electronics retailer that the brick-and-mortar format is still an important way to sell products.

The Minneapolis-based company has battled the “showrooming” effect as more and more people browse in stores and then buy items cheaper online. This has led to fears that the big-box store format is growing obsolete.

But Best Buy has aggressively fought back under new CEO and turnaround expert Hubert Joly, introducing an online price-matching policy, giving employees extra training and cutting costs and revamping stores.

The latest deal is a sign that consumer electronics retailers are sticking with the chain. The company will offer Samsung-dedicated kiosks at 1,400 Best Buy and Best Buy Mobile stores. Shops will offer the full range of Samsung’s mobile products, including smartphones, tablets, laptops, cameras and accessories.

Best Buy shares rose $3.48, or 16.1 percent, to close at $25.13 Thursday, after briefly reaching a 52-week high of $25.30.
