I have shorted 50 shares of Tesla at 407.00, do i hold or Short more ?

I meant the amateurs buying the high/low not whether the trade was profitable.

 

Oh I see, thanks for the clarification.

 

Will continueo to hold the other half short at this rate.

 

Can you buy Tesla less than 100 shares with Option ?

 

No. Each option controls 100 shares. It gives you the right to buy the stock at a specified price. Say, you think TSLA is going to $1,000. Now, it is trading at $367.00. If you buy 100 shares, it will cost you $36,700.00. Now, say the call option at $372 strike is at $3,505 for Oct 16 2020 expiration. If you choose, you can buy 1 call option on TSLA at $372 strike for $3,505. That gives you the right to buy 100 TSLA shares at $372. Assume TSLA goes up to $1,150 on or before, Oct 16 2020, you can now buy 100 TSLA shares @ $372 although, it is now worth $1,150. You can also, just sell the call option and pocket the difference from the $35.05 you paid for it and say, it is now worth $153.00.

 

why did you explain? I asked if you could buy less than 100 shares

 

You buy a call spread. The net delta is a multiplier which shows your proportional ownership of 100 shares.
