OPM, or “Other People’s Money,” is a term widely used on Wall Street and in the broader financial industry. It primarily has two distinct meanings: the use of borrowed funds by individuals or companies to enhance returns on invested capital, and an acronym for “Options Pricing Model.”
OPM as Other People’s Money
Definition
Other People’s Money (OPM) refers to the practice of using borrowed capital to invest with the intention of increasing potential returns. This concept is crucial in leveraging assets to magnify gains.
Mechanism of Leverage
Leverage involves borrowing funds at a lower cost than the potential return on investments. The borrowed funds can significantly enhance the purchasing power of the investor, allowing for larger positions in assets, stocks, or other financial instruments.
Considerations
- Risk: Increased leverage magnifies not only potential returns but also potential losses.
- Interest Costs: Borrowed money incurs interest expenses, which must be considered when calculating net returns.
Example
An individual invests $10,000 of their own money (equity) and borrows an additional $40,000 (debt) to buy $50,000 worth of stocks. If the stock value increases by 10%, the portfolio’s value rises to $55,000. The equity value increases to $15,000, yielding a 50% return on equity, compared to the 10% rise in stock value.
OPM as Options Pricing Model
Definition
Options Pricing Model refers to a mathematical framework used to determine the fair value of options contracts. A significant model under this category is the Black-Scholes Option Pricing Model.
Black-Scholes Model
The Black-Scholes Model is a pivotal formula that calculates the price of European-style options. It considers factors such as the underlying asset’s price, the option’s strike price, time to expiration, risk-free interest rate, and asset volatility.
Where:
- \( C \) = Call option price
- \( S_0 \) = Current price of the stock
- \( X \) = Strike price of the option
- \( t \) = Time to expiration
- \( r \) = Risk-free interest rate
- \( N(d) \) = Cumulative distribution function of the standard normal distribution
- \( d_1 = \frac{\ln(\frac{S_0}{X}) + (r + \frac{\sigma^2}{2})t}{\sigma\sqrt{t}} \)
- \( d_2 = d_1 - \sigma \sqrt{t} \)
- \( \sigma \) = Volatility of the stock
Applications
- Pricing Options: Used to set fair values for buying and selling options.
- Risk Management: Helps in managing and hedging financial risk.
Historical Context
Other People’s Money
The term “Other People’s Money” gained popularity from the eponymous book by Louis D. Brandeis in 1914, which critiqued the financial practices of his time. It has since been a common metaphor in financial markets and corporate finance.
Options Pricing Model
The foundational Black-Scholes Model was published in 1973 by Fischer Black and Myron Scholes, revolutionizing the field of options trading. Their work laid the groundwork for modern financial derivatives pricing.
Comparisons with Related Terms
- Leverage: A broader term embodying the use of borrowed funds. OPM is specifically the borrowed funds themselves.
- Equity: Represents the investor’s own capital. In leveraged investments, equity is the portion not funded by OPM.

Summary
OPM, or Other People’s Money, is a fundamental concept in finance, representing the use of borrowed funds to enhance investment returns. It also denotes the Options Pricing Model, particularly the Black-Scholes Model, a cornerstone in the valuation of options. Both definitions of OPM underscore the role of leveraging strategies and mathematical modeling in maximizing returns and managing financial risk. Understanding these concepts is crucial for anyone involved in financial markets and investment strategies.
