我覺得這個很適合你。如果你已經下單買1000股特斯拉@440，不如買500股，然後賣5個400的Put

Also you intend to hold for long, so, you can sell a 2-3 months out put for much higher premium.

For example, in Jan, you could sell March 21st TESLA 400 put for about $30-$40. 

Net net, in this example, you buy 500 shares at 440, and will be assigned another 500 at the cost of 370-360 (instead of 440) by March 21
