$AppLovin Corporation(APP)$ For such a high growth company I wouldn't short with shares but sell vertical puts OR sell vertical calls as it is preferable because of the high IV.
Look at the 8, 13, 21 and 50EMA and also look for the bounce or rejection off a support or resistance level at 10min chart interval. See chart as it bounced off 13.90 and go long till 16.16.
