S&P 500 Stocks to Avoid: BBY, FTV, KR

Three S&P 500 stocks to avoid include Best Buy (BBY), Fortive (FTV), and Kroger (KR) due to sluggish demand, declining sales, and low gross margins. Best Buy's ongoing store closures and lackluster same-store sales indicate declining customer demand, while Fortive's sales have tumbled 3.1% annually over the last five years. Kroger's declining same-store sales and low gross margin of 2.6% also raise concerns.
