If you’re studying finance, you’ve likely come across questions like which of the following statements best describes a marginal investor. This concept sits at the heart of how stock prices form in markets. In simple terms, a marginal investor helps set the price of a stock based on their buying and selling decisions. Students in undergraduate courses, such as FIN300 or FIN331, often see this in exams. This article breaks it down step by step, with examples and tips to help you grasp it easily.
What Is a Marginal Investor?
In finance, the marginal investor plays a key role in determining stock prices. Think of them as the person on the edge—ready to act if the price shifts just a bit. They believe the stock’s current market price matches its true worth, also known as its intrinsic value. If the price drops slightly, they buy more. If it rises a little, they sell. Otherwise, they hold steady.
This idea comes from corporate finance fundamentals. It assumes markets are efficient, where prices reflect all available information. The marginal investor isn’t the average buyer or seller but the one whose actions balance supply and demand.
For example, imagine a company’s stock trades at $50. A marginal investor sees this as fair. If it falls to $49, they snap up shares, pushing the price back up. If it hits $51, they sell, bringing it down. This keeps the market in stock price equilibrium.
Why Marginal Investors Matter in Stock Markets
Marginal investors influence how prices move in the stock market. They represent rational investor behavior, focusing on facts like company earnings and risks. Unlike emotional traders, they base decisions on data.
In efficient capital markets, these investors ensure prices stay fair. They consider risk and return relationship—higher risk means expecting higher returns. This affects portfolio decision making for everyone.
Statistics show their impact. According to a 2023 study by the CFA Institute, in mature markets like the US and UK, marginal investors (often institutions) drive 70% of daily trading volume. This stabilizes prices and helps small investors too.
