If you are disciplined then buy some way deep OTM Nov. or Dec. call options and sell them immediately before earnings announcement (or hedge them with higher strike calls). Say if you buy some $225s for $5 (or even higher strike price for very cheap), you might see them trading at $10 on the day of earnings if TSLA continues its steady climb to $200. You can then sell them before earnings to make your "respectable but not astronomical profit."
In order for this to work TSLA has to continue going up into earnings; otherwise you risk losing it all.
Thanks sleepy! What do you think about holding way deep OTM calls until after earnings?
