Investing, Trading & Arbitrage

Three different ways to try to make money in markets, the kind of risk each one takes, and why “risk-free” arbitrage is much harder than it sounds.

Three approaches, three kinds of risk

People often use “investing” and “trading” as if they mean the same thing. They do not, and neither is the same as arbitrage. Each approach makes money in a different way and takes a different kind of risk. Understanding the difference helps you choose what fits you and recognize what someone is really selling when they promise returns.
