Stocks closed lower on Wall Street, led by more declines in big technology companies and putting the S&P 500 in the red for the week.

The benchmark index was weighed down by losses in Apple, Amazon and other tech heavyweights. Investors are still keeping a close eye on signs of inflation, which would especially hurt tech sector stocks whose values have soared in recent years. AMC went on another wild ride after executing a big stock sale, closing down 18% after being down even more during the day.
