Shorting Volatility, Really.

Recommended Posts

I'm looking for a way to short volatility in a quantifiable manner, (so not just writing strangles or straddles earning fixed premiums).

 

I'm not looking to simply short volatility either, it would need to be in the nature of an option. In essence, I want to profit from an improbable(<5%) decrease in volatility in order to hedge a strategy which is successfully long volatility most of the time(>95%).

 

Buying puts on the VIX would be lovely, but as far as I can tell the VIX is garbage and just negatively correlates the indexes more than anything... it doesn't seem to care much for volatility in price to the upside.

 

My knowledge of options is limited but if you know what I'm looking for go ahead and say it and I'll understand. If it's doable on an intra-day level, even better. If this method isn't common knowledge then I'll just get creative. thanks.

You should check out VIX futures -- and more specifically, study the fascinating relationship of VIX vs VIX Futures.

 

Larry McMillan has done some excellent work on this topic. Read the first few pages of this piece he did for a primer on the 'term structure of VIX'...

Thanks for the reply Frank. I don't believe the purpose of the VIX as a 30-day fear gauge is what I need though...

 

I'm beginning to think that writing a strangle deep in-the-money is in fact an option with the odds I'm looking for.

What exactly are you trying to hedge? There are plenty of ways to short volatility, especially in terms of hedging. But I think writing straddles and strangles on the SPY might be a good start.

 

yeah I think a short strangle near-the-money works... I'm not used to options :doh:. I'm just using the options simulator at http://www.888optionsnet.com and that strategy so far fits best for me.

 

I'm hedging an improbable stochastic... for example the probability that a stock trades between 30 and 32 ten times before it breaks to touch 33 is very low. So I wanted a low risk, low probability, high reward trade to hedge against this.

 

See, a far otm "VIX" put would work too if it actually did index volatility.

Ok I found it, was a long butterfly call. I was looking for something that went positive on theta exponentially. B-E-A-utiful .

 

thanks for the help :).

 

nice!

how accurate was the assumptions in frequentist black scholes nonsense on vega in what you can price now on the instrument compared with when you posted this? oops...if vega doesn't make sense all the other greeks are just random.

I didn't come to this via a stochastic process. A random number generator didn't just pick me to most this.

what the hell are you talking about?

 

Go back to the day you started this thread and compare it to today....

How much more could you possibly be wrong about shorting vega?

You did not do anything wrong as far what you know...the problem simply sits in what you do not know. Frequentist stats and probablity are nonsense.

Markets are Bayesian, I've bet my life on that idea. If you want to read about stochastic process being ripped to shreads then get E T Jaynes book.

It is literally the bible if your interested in the "quantification of market data".

but you don't know what I'm doing. I'm not just shorting volatility on its own... I was looking for an option as a hedge for a strategy I want to improve. What's wrong with using options (particularly a butterfly) to bet against price finishing where it started? I think my sharpe ratio is better off with it than without.

 

You really think that probability is useless? That, with enough data, the stochastic process doesn't break even. The distances for price to travel and the frequencies in which they should occur relative to one another don't matter? On what time frames even? Maybe the larger the time frame, the less efficient. But how much less efficient? The market isn't random, but it's not stupid either.

 

I'm not leaving behind that logic unless you prove me wrong. I'm not driving myself crazy trying to debunk my common sense either for something that would be a pain in the ass to prove lol.

    • Be careful who you blame.   I can tell you one thing for sure.   Effective traders don’t blame others when things start to go wrong.   You can hang onto your tendency to play the victim, or the martyr… but if you want to achieve in trading, you have to be prepared to take responsibility.   People assign reasons to outcomes, whether based on internal or external factors.   When traders face losses, it's common for them to blame bad luck, poor advice, or other external factors, rather than reflecting on their own personal attributes like arrogance, fear, or greed.   This is a challenging lesson to grasp in your trading journey, but one that holds immense value.   This is called attribution theory. Taking responsibility for your actions is the key to improving your trading skills. Pause and ask yourself - What role did I play in my financial decisions?   After all, you were the one who listened to that source, and decided to act on that trade based on the rumour. Attributing results solely to external circumstances is what is known as having an ‘external locus of control’.   It's a concept coined by psychologist Julian Rotter in 1954. A trader with an external locus of control might say, "I made a profit because the markets are currently favourable."   Instead, strive to develop an "internal locus of control" and take ownership of your actions.   Assume that all trading results are within your realm of responsibility and actively seek ways to improve your own behaviour.   This is the fastest route to enhancing your trading abilities. A trader with an internal locus of control might proudly state, "My equity curve is rising because I am a disciplined trader who faithfully follows my trading plan."

    • SELF IMPROVEMENT.   The whole self-help industry began when Dale Carnegie published How to Win Friends and Influence People in 1936. Then came other classics like Think And Grow Rich by Napoleon Hill, Awaken the Giant Within by Tony Robbins toward the end of the century.   Today, teaching people how to improve themselves is a business. A pure ruthless business where some people sell utter bullshit.   There are broke Instagrammers and YouTubers with literally no solid background teaching men how to be attractive to women, how to begin a start-up, how to become successful — most of these guys speaking nothing more than hollow motivational words and cliche stuff. They waste your time. Some of these people who present themselves as hugely successful also give talks and write books.   There are so many books on financial advice, self-improvement, love, etc and some people actually try to read them. They are a waste of time, mostly.   When you start reading a dozen books on finance you realize that they all say the same stuff.   You are not going to live forever in the learning phase. Don't procrastinate by reading bull-shit or the same good knowledge in 10 books. What we ought to do is choose wisely.   Yes. A good book can change your life, given you do what it asks you to do.   All the books I have named up to now are worthy of reading. Tim Ferriss, Simon Sinek, Robert Greene — these guys are worthy of reading. These guys teach what others don't. Their books are unique and actually, come from relevant and successful people.   When Richard Branson writes a book about entrepreneurship, go read it. Every line in that book is said by one of the greatest entrepreneurs of our time.   When a Chinese millionaire( he claims to be) Youtuber who releases a video titled “Why reading books keeps you broke” and a year later another one “My recommendation of books for grand success” you should be wise to tell him to jump from Victoria Falls.   These self-improvement gurus sell you delusions.   They say they have those little tricks that only they know that if you use, everything in your life will be perfect. Those little tricks. We are just “making of a to-do-list before sleeping” away from becoming the next Bill Gates.   There are no little tricks.   There is no success-mantra.   Self-improvement is a trap for 99% of the people. You can't do that unless you are very, very strong.   If you are looking for easy ways, you will only keep wasting your time forgetting that your time on this planet is limited, as alive humans that is.   Also, I feel that people who claim to read like a book a day or promote it are idiots. You retain nothing. When you do read a good book, you read slow, sometimes a whole paragraph, again and again, dwelling on it, trying to internalize its knowledge. You try to understand. You think. It takes time.   It's better to read a good book 10 times than 1000 stupid ones.   So be choosy. Read from the guys who actually know something, not some wannabe ‘influencers’.   Edit: Think And Grow Rich was written as a result of a project assigned to Napoleon Hill by Andrew Carnegie(the 2nd richest man in recent history). He was asked to study the most successful people on the planet and document which characteristics made them great. He did extensive work in studying hundreds of the most successful people of that time. The result was that little book.   Nowadays some people just study Instagram algorithms and think of themselves as a Dale Carnegie or Anthony Robbins.
