Background
The strike price is a foundational concept in options trading, representing a predetermined price at which the buyer of the option can buy (for call options) or sell (for put options) the underlying asset.
Historical Context
The usage of strike prices in financial markets became prominent with the development of standardized options trading on formal exchanges in the 1970s, notably with the establishment of the Chicago Board Options Exchange (CBOE).
Definitions and Concepts
- Strike Price (Exercise Price): The set price at which an option can be exercised. For call options, this is where the holder can buy the underlying asset. For put options, it’s the price at which the asset can be sold.
Major Analytical Frameworks
Classical Economics
Whilst classical economics typically did not deal directly with financial derivatives such as options, foundational concepts such as pricing mechanisms influence derivative valuation.
Neoclassical Economics
Neoclassical finance theories brought new insights into options pricing. The Black-Scholes model, a cornerstone in neoclassical option pricing, assists in determining the theoretical price of options, factoring in the strike price.
Keynesian Economics
Keynesian economics does not directly delve into the intricacies of options and derivatives but acknowledges the role of financial markets in expressing business expectations and managing risks. The elasticity of investments and market correcting mechanisms can interact with the valuation of options, including their strike prices.
Marxian Economics
Marxian economic analysis views financial derivatives—including options—as part of the capitalist financial superstructure, reflecting on how such instruments allure speculative capital, amplified by varying strike prices.
Institutional Economics
Examines how institutional arrangements, regulations, and exchanges that trade options operate. It observes the strike prices through the lens of regulatory frameworks and market microstructures.
Behavioral Economics
Behavioral economics evaluates how psychological factors and cognitive biases affect peoples’ perceptions and decisions on options trading, including preferences for certain strike prices based on perceived probabilities and payoffs.
Post-Keynesian Economics
Post-Keynesian approaches might scrutinize the real-world conditions of liquidity, brokerage influences, and the macroeconomic environment in influencing the setting and effects of strike prices in options markets.
Austrian Economics
Austrian Economics emphasizes the role of entrepreneurship and speculation. It might view strike prices as determinants strategically set by investors to hedge risk or speculate on future market movements, independent of purely mathematical models.
Development Economics
In development economics, the strike price could symbolize complex financial derivatives helping investors manage risks in emerging technologies and markets, potentially enabling economic development through structured financial instruments.
Monetarism
While Monetarism focuses predominantly on money supply and inflation control, options pricing, including strike prices, can indirectly influence monetary policy by affecting investment decisions and derived demand in broader financial markets.
Comparative Analysis
Understanding how the strike price interacts with factors like volatility, time till expiration, and interest rates across different valuation models highlights its central importance in determining options value in various economic schools of thought.
Case Studies
Case studies often explore specific historic market events to illustrate how changing market conditions can impact the setting and resultant financial strategies involving strike prices.
