Equity securities (also known as 'stocks' or 'shares') are financial instruments that represent an ownership stake in a corporation. Think of a company as a giant pizza. When you buy an equity security, you are buying a slice of that pizza. You become a part-owner, a shareholder, with a claim on the company's assets and earnings. Companies issue these shares to raise money—or capital—to fund their operations, expand, or launch new projects. This is often done through an Initial Public Offering (IPO), after which the shares typically trade on a stock exchange like the New York Stock Exchange or the London Stock Exchange. For a value investor, owning a stock isn't about trading a blinking symbol on a screen; it's about owning a piece of a real, tangible business. The goal is to understand that business so well that you can confidently determine what your slice is truly worth, independent of its daily market price.
Owning equities is one of the most powerful ways to build wealth over the long term. The rewards for shareholders come in two primary forms:
For a true investor, the appeal lies in participating in the success of a great business. As the company grows its earnings year after year, the value of your ownership stake should grow with it.
Not all stocks are created equal. They generally fall into two categories, each with different rights and features.
This is what most people mean when they talk about “stocks.” As a holder of common stock, you are a true part-owner of the company.
Preferred stock is a bit of a hybrid, with characteristics of both stocks and bonds.
Legendary investor Benjamin Graham taught that a stock is not just a ticker symbol; it is an ownership interest in an actual business, with an underlying value that does not depend on its share price. This philosophy is the bedrock of value investing.
Before buying a single share, a value investor acts like a business analyst. You should ask fundamental questions:
You are not betting on market sentiment; you are investing in the long-term prospects of the business itself.
The most crucial concept for a value investor is understanding the difference between price and value.
The goal is to calculate a conservative estimate of a business's intrinsic value and then wait for the market to offer you a price well below that value. That discount is what Benjamin Graham called the Margin of Safety—your protection against bad luck, bad analysis, or a downturn in the economy. Buying a great business is good, but buying it at a wonderful price is even better.
