Lavon Pricing Models and Volatility Problems

Most traders are aware of the volatility-related problem with the best-known option pricing model, Black-Scholes. The assumption under this model is that volatility remains constant over the entire remaining life of the option.

Of course, this makes no sense. Volatility changes constantly, ands this points out the problem with any model. It must assume that volatility remains unchanged for the math to work out. Even so, the assumption is so flawed that it makes the model unreliable. Making matter worse, the BSM has many other flaws as well. In math, one flaw is bad enough; but when you face at least 8 flaws (as BSM dies), it means there is zero reliability. [1]


But it gets worse.


Volatility is unpredictable.


Volatility does not anticipate direction or degree of price change.


The timing of price changes also affects volatility.


Moneyness also affects volatility.


Time to expiration also affects volatility.


Type of option trade distorts volatility assumptions.


Adjusting for stochastic volatility (SV) creates yet another variable.

The problem remains: No pricing model can accurately

[1] The 8 most serious flaws of BSM are: (1) Volatility remains constant (2) there is no restriction on buying or selling the underlying; (3) no tax consequences apply to profits; (4) interest rates are fixed and available to all; (5) no transaction costs are in effect; (6) trading is continuous without any gaps in price movement; (7) volatility is independent from underlying price; and (8) price changes are normally distributed.

  • Option Arbitrage Risks

    Options traders dealing in arbitrage might not appreciate the forms of risk they face. The typical arbitrage position is found in synthetic long or short stock. In these positions, the combined options act exactly like the underlying. This creates the arbitrage.

  • Historical Drawdowns for Global Equity Portfolios

    Globally diversified equity portfolios typically hold thousands of stocks across dozens of countries. This degree of diversification minimizes the risk of a single company, country, or sector. Because of this diversification, investors should be cautious about confusing temporary declines with permanent loss of capital like with single stocks.

  • Types of Volatility

    Are most options traders aware of five different types of volatility? Probably not. Most only deal with two types, historical and implied. All five types (historical, implied, future, forecast and seasonal), deserve some explanation and study.

  • Premium at Risk

    Should options traders consider “premium at risk” when entering strategies? Most traders focus on calculated maximum profit or loss and breakeven price levels. But inefficiencies in option behavior, especially when close to expiration, make these basic calculations limited in value, and at times misleading.

  • Diversified Leveraged Anchor Performance

    In our continued efforts to improve the Anchor strategy, in April of this year we began tracking a Diversified Leveraged Anchor strategy, under the theory that, over time, a diversified portfolio performs better than an undiversified portfolio in numerous metrics.
