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

One more factor  not priced into the option formula

 

 

The value of the euro

 

German exports become dearer  and dividends go down  , profit warnings increase  , corporate fraud increases     vv

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

    • This week, Shiba Inu enters a new phase, prompting speculation about its price prediction. Investors aim to surpass the $0.00003 mark, a key milestone in Shiba Inu's trajectory. The burn rate, currently at 164.94%, reflects community dedication to reducing SHIB's supply, influencing price predictions. Monitoring retail sentiment is vital for price prediction models. Despite a 4.12% decrease in daily trading volume to $363,490,960, sustained activity is crucial for price movements. Declining whale activity, with only $29.93 million traded in 24 hours, may impact predictions.   Optimism surrounds Shibarium and partnerships, factors affecting shiba inu coin price prediction. Despite selling pressure, SHIB finds support at the 50-day Exponential Moving Average (EMA), vital for stability. Whale transactions, totaling 1.9 trillion SHIB in 24 hours, indicate continued engagement, yet price movement remains subdued. To surpass resistance levels and initiate an upward trend, SHIB needs increased market support and buying interest. Despite challenges, the community remains optimistic about SHIB's future, shaping price predictions for investor

Wave Cancel invalid level: 41239   The NIKKEI 225 Elliott Wave Analysis on the daily chart focuses on understanding the current market dynamics through the lens of the Elliott Wave Principle. This analysis identifies the function as a counter trend, indicating that the market is currently in a phase that moves against the prevailing trend. The mode of this movement is corrective, meaning it is a temporary retracement or consolidation within the larger trend.   The primary wave structure under scrutiny is orange wave C, which is positioned within navy blue wave 4. This suggests that the market is in the fourth wave of a larger wave sequence, and specifically, within the third sub-wave of this fourth wave. The direction for the next higher degree is towards navy blue wave 5, which indicates that once the current corrective phase is complete, the market is expected to resume its primary trend direction in the fifth wave.   Details from the analysis highlight that orange wave B of wave 4 is likely completed, setting the stage for orange wave C to come into play. Orange wave C is part of the corrective pattern and represents the final leg of the correction before the trend resumes. The completion of orange wave B signifies a pivotal point in the market, where the correction is likely moving towards its end phase, preparing for the continuation of the main trend.   An invalidation level is set at 41239. This level is crucial because if the market price reaches or exceeds this point, it would invalidate the current wave count and necessitate a reevaluation of the wave structure. This invalidation level acts as a safeguard for traders, ensuring they can adjust their strategies if the market behaves unexpectedly.   In summary, the NIKKEI 225 Elliott Wave Analysis on the daily chart provides a detailed outlook of the market's corrective phase within a counter trend. With orange wave B of navy blue wave 4 likely completed, the focus is now on orange wave C. Traders should be aware of the invalidation level at 41239, which serves as a critical point for reassessing the wave count. This analysis aids in making informed decisions by anticipating the next phase of market movement within the Elliott Wave framework.     NIKKEI 225(N225) Elliott Wave Analysis Trading Lounge Weekly Chart NIKKEI 225(N225) Elliott Wave Technical Analysis FUNCTION: Counter Trend MODE: corrective STRUCTURE:orange wave C POSITION: navy blue wave 4 DIRECTION NEXT HIGHER  DEGREES: navy blue wave 5 DETAILS orange wave B of wave 4 looking completed, now orange wave C is in play. Wave Cancel invalid level: 41239   The NIKKEI 225 Elliott Wave Analysis on the weekly chart provides insights into the market's current behavior using the Elliott Wave Principle. This analysis identifies the market function as a counter trend, indicating that the current movements are against the primary trend. The mode is corrective, suggesting a temporary retracement or consolidation phase rather than a continuation of the main trend.   The primary wave structure being analyzed is orange wave C, which is part of a larger corrective pattern. This wave is positioned within navy blue wave 4, indicating that the market is in the fourth wave of a broader wave sequence. Following the completion of this corrective phase, the market is expected to proceed to navy blue wave 5, resuming the primary trend direction.   The analysis details that orange wave B of navy blue wave 4 appears to be complete. This completion signals a critical point in the corrective pattern, as it suggests the market has finished the preceding segment of the correction and is now transitioning into orange wave C. This wave represents the final leg of the correction before the market resumes its main trend.   A key aspect of the analysis is the invalidation level set at 41239. This level is crucial for traders and analysts because if the market price reaches or surpasses this point, the current wave count would be invalidated. This means the expected wave structure would no longer be valid, necessitating a reassessment of the market's wave patterns. The invalidation level serves as a safeguard, ensuring that strategies can be adjusted if the market does not behave as anticipated.   In summary, the NIKKEI 225 Elliott Wave Analysis on the weekly chart outlines a corrective phase within a counter trend. With orange wave B of navy blue wave 4 likely completed, the focus shifts to the development of orange wave C. This phase is critical as it marks the final part of the correction before the market resumes its primary trend towards navy blue wave 5. The analysis highlights the importance of the invalidation level at 41239, which helps in validating the current wave count and adjusting trading strategies accordingly.     Technical Analyst : Malik Awais Source : Tradinglounge.com get trial here!
