Why a 10% Average Return Tells You Almost Nothing About Any Single Year

If someone told you that the U.S. stock market has finished a given calendar year higher than it started roughly seventy-three times out of the last ninety-nine, you might reasonably conclude that stocks are a fairly comfortable bet. If someone then told you the long-run average annual return over roughly a century is about 10%, you might imagine a market that quietly compounds wealth every year, like a savings account with slightly better manners. Neither impression survives contact with the actual year-by-year record.

When “Safe” Cash Is Quietly Losing You Money

Ask most savers why they keep a large balance in a savings account rather than in the stock market, and the answer usually comes down to a single word: safety. Cash cannot fall to zero overnight, it is there when you need it, and it never sends you an alarming statement after a bad month for shares. But that comfort has a cost that rarely shows up on any statement — and according to Vanguard’s head of behavioural economics research, Andy Reed, it is a cost the UK is paying on a very large scale.

And sometimes — often enough to keep the genre alive — they are vindicated. Yet the uncomfortable truth that rarely makes headlines is this: even a correct bubble call is almost never sufficient to make you money, or to protect you at the right moment.
