Beginner Q: Buying Call = Selling Put? Misc Q's...

Quote from xBoba:

Hi guys, I'm currently in the process of understanding Options, and I have 3 questions:

1.) I'd like to know if the analogy of buying a call is the same as selling put, and if buying a put is the same as selling a call.

If I buy a call, I expect the price of the underlying to increase.
If I sell a put, I expect the price of the underlying to increase.

If I buy a put, I expect the price of the underlying to decrease.
If I sell a call, I expect the price of the underlying to decrease.

-------------------------

2.) When I want to buy a put option, would the seller (underwriter) be the person selling the call? Please reference question 1.

------------------------

3.) Can I sell a call without owning the option? Or would I have to own the call first in order to sell it?

------------------------

4.) When I buy a put, it is granting me the right to sell the underlying stock. Does this mean I have to own the shares first before being able to buy a put?

------------------------


I just want to re-confirm some of these questions as I am pretty confident that what I have in mind is correct. And yes, I am currently reading a Beginner to Options book.

Thanks!

The most important thing you need to understand is that a vanilla option, no matter it is a call or put, always has positive gamma. That means if you buy options you benefit from the increase of volatility and suffers from time decay.

In my mind, managing gamma is the key to trade options. Directional movement is secondary.

Awesome explanation.


When you say that "you can sell a call that you have previously purchased," does this mean that if I were to buy a call, hold, then sell , I would be a "call seller?"

What I want to understand is what constitutions a call seller. I'll give 2 scenarios; please tell me if they are both considered "call sellers."

Scenario 1: I sell a May 50 call for $3 (I get $300 profit). This stock falls to $40, and the option value falls to $1. I can buy it back for $1, which will cost me $100, and my profit would be $200 (300-100). And I just let the option expire worthless because exercising it will give me a loss since I shorted at $50 and buying at $40. (This part is redundant but I just wanted confirmation that my thought process is correct.)

Scenario 2:I buy a May 50 call for $3 (I pay $300 premium). The stock rises to $60, and the option value rises to $5. Because of the increase in the option value, I want to sell it to someone else, who is expecting the market value of that stock to go down. In this scenario, do I also become a "call seller?"

Thanks!

The phrase "option sellers" usually refers to people who write options, not people who sell an option they previously purchased.

If I buy a call option and then decide I don't want it later so I sell it, I wouldn't say I'm an "option seller." I mean technically I did just sell an option, but I don't think that's what it usually means.

If you're doing like covered calls or something it's probably less confusing to just say "I'm going to write an option."

The counter-party has no idea (unless prearranged) that a write isn't a sell to close. You can only buy or sell an option. There is no gains to be had by delving into semantics.

You can sell (short) an option to open a position. There is a margin req as the risk is greater than the reward.

You can spread (buy a call, sell another call) or trade combinations (buying and selling of calls and puts).
