The Beauty Contest
This is more of a concept than a traditional proverb, but it was coined by the famous economist John Maynard Keynes, who compared the stock market to a newspaper beauty contest.
Investing is, in a sense, like a beauty contest game. To win, you shouldn’t pick the face you find most beautiful — you should predict who others will find most beautiful.
Similarly, in stock investing, you don’t buy the company you think is best — you invest in the company other investors are likely to value highly. This concept highlights the critical importance of market psychology and anticipating others’ behavior.
The Shoe-Shine Boy
This proverb (more accurately, an anecdote) represents a situation where people who normally have no interest in investing are suddenly all talking about it — broadly signaling that the market is in bubble territory.
The story dates to just before the Great Depression in America (1929). Investor Joseph P. Kennedy (later the father of President John F. Kennedy) was getting his shoes shined on the street when the shoe-shine boy started giving him stock tips. At the time, the U.S. market was in a bubble — anyone could make money buying stocks, and even ordinary people and eventually children were getting into the market.
Kennedy realized that when even a shoe-shine boy — someone who would normally show zero interest in investing — was talking about stocks, something was seriously wrong. He concluded the market was dangerously overheated and sold his positions shortly after. The Great Depression followed.
Today, the same principle applies: when people who normally never discuss investing start talking about stocks, it’s often a sign that a major crash is approaching.
When Everyone Is Bullish, Become a Fool and Sell
This proverb has essentially the same meaning as “The shoe-shine boy.” “When everyone is bullish” describes a state where every market participant and every media outlet is saying “prices will keep rising” — universal conviction in further gains.
The proverb continues: “become a fool (tawake) and sell your rice.” In other words, when everyone is optimistic, that’s the moment to start selling.
Universal bullishness is generally the hallmark of a bubble, and a crash is usually near. When you detect that signal, getting out entirely is often the wise move.
The Price That Astonishes Everyone Marks the Turning Point
This proverb refers to prices that are so extreme — unbelievably high or unbelievably low — that they leave everyone speechless. Such extreme prices may signal a turning point.
When something is so high that no one can imagine it going higher, there is no room left to rise. When something is so low that no one can imagine it going lower, there is no room left to fall. At such extremes, investors should step back, recognize the situation objectively, and prepare for a reversal.
That said, what counts as “astonishing” is very hard to judge in real time — it’s usually only obvious in hindsight, after the subsequent crash or rally. Still, when a stock makes an extreme move in a short period, remember this proverb and consider whether a reversal might be coming.
When Everyone Is Bearish, Become a Fool and Buy
This proverb is the opposite of “When everyone is bullish, sell.” When the entire market has been crushed by a major crash and extreme pessimism sets in — “when all the mountains and fields are painted bearish” — that may actually be a buying opportunity.
“Become a fool (ahō) and buy your rice” means: when everyone is pessimistic and selling in a panic, have the courage to step up and buy.
When market participants and media are dominated by extreme pessimism, the market is often just before a bottom — and that’s when buying can be the winning move.
That said, timing this correctly is extremely difficult. After a major crash, another wave of selling may follow. Think carefully before acting, and do your own analysis.
Buy When Others Sell; Sell When Others Buy
This proverb combines the previous two — “when everyone is bullish, sell” and “when everyone is bearish, buy” — into one statement.
The meaning is clear: buy what everyone has abandoned in despair, and sell what is at the height of popularity and showing signs of a peak.
The frequency of similar proverbs tells you all you need to know: the secret to winning in the market is to buy when others sell, and sell when others buy.
You may have heard “buy low, sell high” as the basic rule of investing. These proverbs are all teaching the same contrarian principle.
There Is a Path Behind the Crowd, and Flowers at Its End
One of the most famous stock market proverbs of all. It carries the same meaning as “Buy when others sell; sell when others buy.”
A free translation: “Hidden behind the road everyone else is taking, there is a secret path — and at its end lies a breathtaking garden of flowers.”
“There is a path behind the crowd” means timing your investments differently from the crowd — contrarian investing. “Flowers at its end” represents the large returns that await.
Just like the proverbs before it, this one teaches that to win in the market, you must do what others are not doing.
A related proverb: “Go toward the friendless direction” (友なき方へ行くべし) — meaning head toward where no one else is going.
