Whether you're a seasoned investor or just getting started, it's never fun to see your holdings lose value. With that in mind, here's why three Motley Fool contributors selected Poshmark (NASDAQ: POSH), Lululemon Athletica (NASDAQ: LULU), and Chewy (NYSE: CHWY) as great stocks to buy during the current market sell-off.
