Do a combo of ratio calls and ratio puts.
Ratio call could allow you to capture the upside (assume TSLA will not go much higher than 380). And ratio puts can give you better cost average than naked put
Both can be entered with almost $0 premium.
For example, Oct 340:365 ratio call is $0, and breakeven is all the way to 390
Oct 330:310 ratio put is almost $0, and breakeven is 290
