Put options exercised in TSLA which results in short cover for my -200 TSLA position.
I have no position in TSLA store to any TSLA options as of today.

Net profit in #TSLA4Tesla is $39,005. On one hand, I feel time pressed. I would like to buy one before Arian's next birthday which on December 1st. As of the moment, TSLA stock looks well priced so not forcing me into any trade. I am waiting for some clear direction to emerge.
On the other hand, I am thinking expand this beyond TSLA. Maybe trading some other Auto stocks or may be playing Oil. The only reason for that is to put a deadline on this experiment- instead of letting it go on and on.
