Palantir Technologies' (PLTR -0.32%) share price soared after the company delivered another quarter of exceptional revenue growth and continued improvements in profitability. CEO Alex Karp described the quarter as "otherworldly" in the company's earnings release, and investors sent the stock higher on the news. Palantir will have to continue delivering very strong quarterly earnings reports to keep pushing the stock higher from here. What will it take for Palantir stock to keep climbing? Management is already forecasting a slowdown in revenue growth in the back half of the year.
