betting on the inefficiency of the option formula


Recommended Posts

George sorros quote 

 

Markets are constantly in a state of uncertainty and flux and money is made by discounting the obvious and betting on the unexpected.

 

The magic formula bets on the unexpected  and returns are like george sorros  below 

 

 

We buy options   , but  the option formula pricing is innefficient.The option formula does not price in volatility of unexpected events

 

examples of unexpected events

 

1)stock market bubble

2)chinese devaluation impact on stock market bubbles bursting

3)greek crisis /financial crisis /euro crisis

4)profit warnings 

5) fraud by corporate companies

6) other unexpected events  like war  ,terrorism   etc

 

if you buy options  , at time of buying options  these unexpected factors are not priced into the option price , option buyers gain when these unexpected events happen , as prices become extremely volatile and unpredictable.

 

Additional edge to beat the option formula can be found in systems designed to beat the formula  , example progressive betting  formulas on the option pricing  models  or systems and combinations of unique option strategies designed to beat the option formula.

The model makes certain assumptions, including:

  • The options are European and can only be exercised at expiration
  • No dividends are paid out during the life of the option
  • Efficient markets (i.e., market movements cannot be predicted)
  • No commissions
  • The risk-free rate and volatility of the underlying are known and constant
  • Follows a lognormal distribution; that is, returns on the underlying are normally distributed.

The formula, shown in Figure 4, takes the following variables into consideration:

  • Current underlying price
  • Options strike price
  • Time until expiration, expressed as a percent of a year
  • Implied volatility
  • Risk-free interest rates

Hi,

There are few things in your post which are misleading.

The Black scholes option formula is not efficient  as you described, but it's never used as such.

But that's why no one since 1987 use it raw like that.

You will not be able to buy an option on the market priced as such, therefore, there are no inefficiency to take advantage from. Sorry, there are no free lunch ! Only the usual tradeoff risk versus money...

 

What your investopedia link doesn't speak about, is how people really use it. You need to tweak the formula. For example, the volatility is constant under black scholes assumptions, which is wrong on the market. So you use the smile to correct that effect

(https://en.wikipedia.org/wiki/Volatility_smile)

 

Concerning unexpected events, well, the level of the volatility reflects the likeliness of an unexpected event seen by the actors on the market. The value of the options is pricing those events, so again, there is no inefficiency there...(on that matter you could take advantage of the black swann effect if you can hold a position 10 years but that's another story)

 

You can  take advantage of the situation if you can foresee an unexpected event better then everyone else. But then, you are taking risk to be wrong. If you make money , it won't be because option are mispriced, but because you took a risk.

 

so no, options are not inefficient when properly priced, and there are no free lunch

    • US Dollar (DXY) Daily Price and Analysis US Q1 GDP may stall the greenback’s advance. A 20-year high nears for the US dollar. The multi-month US dollar rally continues with the greenback printing a fresh high today ahead of the first look at US Q1 GDP at 12.30 GMT. The US dollar basket (DXY) has been boosted by renewed weakness in the Euro and the Japanese Yen, as investors move from lower-yielding to higher-yielding currencies, while safe-haven flows continue to benefit the greenback. The US growth release later in the session is expected to show a sharp slowdown from the robust Q4 figure of 6.9%. The markets are currently pricing in growth of just 1% for the first three months of this year, with the slowdown mainly due to a reduction in inventory accrual over the quarter. This release is unlikely to move the greenback, unless there is a large miss or beat, as the Fed believe that 2022 US growth will be robust enough to let them tighten monetary policy sharply without damaging the economy. The latest US Core PCE data – the Fed’s preferred inflation reading – is released on Friday and this may have more effect on the US dollar than today’s GDP data. For all market moving economic data and events, see the DailyFX Calendar. The ongoing US dollar rally has been aided by weakness across a range of G7 currencies including the Euro, the Japanese Yen, and the British Pound. The Euro continues to battle with lowly growth expectations, exacerbated by energy concerns, the British Pound is mired by weak economic data, while the Japanese Yen is in freefall as the BoJ continues with its ultra-loose monetary policy.   The US dollar continues to press higher and looks set to break above 103.96, the March 2020 high. Above here the US dollar would be back at levels last seen nearly two decades ago. The March resistance will likely hold in the short-term, especially with month-end portfolio rebalancing at the end of the week, but US dollar strength is set to continue in the months ahead.
