By the end of this lesson you understand why a higher expected return usually comes with higher risk, and what "expected" means in that context.
\nAn investment's return is the gain -- or loss -- it produces, usually expressed as a percentage of the amount invested. When people talk about "expected return," they aren't talking about a guaranteed outcome, but an estimate: the most likely result, given the risk the investment carries.
\nIn financial markets there's a general relationship between risk and expected return: to take on more risk, investors demand, in exchange, the possibility of earning more return. The logic is simple -- if two investments offered the same expected return but one carried more risk than the other, everyone would prefer the lower-risk one. This causes market prices to tend to adjust until an investment's extra risk comes with an extra potential return -- otherwise, no one would be willing to take on that extra risk with nothing in exchange.
\nIt's essential not to confuse "higher expected return" with "higher guaranteed return." They're practically opposites: a higher expected return reflects that the range of possible outcomes is wider -- you can gain more, but you can also lose more -- not that you'll necessarily get a better result. Looking only for the investment with the highest possible return, without considering the risk it carries, treats two linked magnitudes as if they were independent.
\nA stock and a bond from the same company illustrate this relationship well. The bond offers interest agreed in advance and, barring a default by the company, a fairly predictable outcome. The stock offers no agreed-upon figure: its result depends entirely on how the company performs in the future, and it can vary much more, both for better and for worse. That's why the market generally demands a higher expected return for a stock than for a bond from that same company -- as compensation for the higher risk of having no result agreed in advance.
\nTaking on more risk is, generally, the condition for being able to aim for a higher expected return -- never a guarantee of getting it. Risk and expected return are linked, not independent magnitudes.
\nWhy isn't "higher expected return" the same as "higher guaranteed return"?

That deviation can go either down (worse than expected) or up (better than expected); in everyday language, people almost always think of the negative side, but technically risk is uncertainty in both directions, not just the downside.\n\nThis distinction matters because it changes the question you should ask before investing.

Each has a different nature and, therefore, a different uncertainty about its future outcome.
