Even as inflation remains high and the possibility of a recession looms, some investors were tiptoeing back into the market Friday, looking for stocks that still have long-term growth potential -- and bidding up shares of Amazon, MercadoLibre, and Roku in the process. Against that declining backdrop, shares of Amazon (NASDAQ: AMZN) gained as much as 2.4%, MercadoLibre (NASDAQ: MELI) climbed as much as 4.6%, and Roku (NASDAQ: ROKU) surged as much as 5.3%. Amazon, MercadoLibre, and Roku haven't been immune -- they're down 42%, 66%, and 82%, respectively, from the highs they hit last year.
