Hi, I’m Vladimir Eremin, I am a data scientist during the day and sometimes at night as well. Welcome to my blog, where I share stories hidden behind data. Here, I explore the realms of data science, quantitative finance, and problem-solving. This blog has started as my offline journal and and some point I decided to start publishing in the hope it may be helpful for others as well. Please look around if something catches your eye. Feel free to reach out to me if you have questions or suggestions. Additionally, for those of you in NYC, I co-host a data science meetup - if you’re around, I’ll be happy to meet you at our next event!

Closed straddle strategy

by Vladimir

Here also the expiration of my options portfolio came that is the completion of an experiment.

Now I can sum up the full result and analyze the effect.

The portfolio kept one and a half months and had 3 modifications:




  • Initial formation of a call spread in the form of "straddle."
  • At renewal of a trend closing of the left leg and transition to a long stake
  • Change to a bull call spread.




I described the first two points in the previous post (here the reference: https://vk.com/wall-103610476_242? w=page-103610476_53705610). I will dwell on the last a little:

After the closing of the left leg (sale of fetters options), I had a clean equivalent of Long. Considering that I work with options, but not with the primary market, a sin was not to seize all additional opportunities to maximize income. And I made decisions to begin to sell stakes "out of money," thereby forming "a bull call spread."

Eventually, at me the call spread 15000-17250 turned out. In such look, the position came to expiration.

I will tell at once, the sale of the option I well "cut off" to myself profit as sold a stake too close to money in the growing market. Of course, it was covered with other option, but the current variation took away a lot of money when the price of the option began to grow with a growth of the price (At the market in 17350, the option sold by me became "on money", so its price grew as much as possible. Here schedule of a teta.








Apparently, the market was closed to its maximum values. And it left to me in kopek.

Morals: it is impossible to underestimate the force of a trend and to form very narrow spreads.



Anyway, I consider that I the idea well worked myself. Both options were executed and made profit on "a long position."








As a result, the profitability of all portfolio in 1.5 months made 25.13% that in itself is quite good.








I think that about new year I will leave work with options so far, it is too much another matters, plus it will be necessary to analyze all mistakes once again. All best!
