What is manic-depressive market?
A manic-depressive market is one where prices swing wildly from optimism to pessimism. The term comes from Mr. Market's swings, which show emotional extremes. These mood swings create bargains in gloom for anyone who buys when others panic.
You see this in every crash and boom. Prices don't move on facts alone. They move on emotion. When optimism peaks, everyone buys. When pessimism hits, everyone sells. That's the manic-depressive market cycle.
Why does the market swing this way?
Benjamin Graham named it in 1949. He called the stock market a manic-depressive partner named Mr. Market. Each day he quotes you a price for your share. He never forces a trade. The price is an offer, not an order.
Mr. Market serves you; he does not guide you. His manic-depressive mood is a servant, not a master. Ignore his low quote and wait. Buy when his gloom prices quality far below its worth. You set the terms.
How do market moods affect your money?
Your portfolio takes the hit. Buy high and you lose. Sell low and you lock in losses. Emotional extremes and market moods make you overpay and underpay. Set rules before the panic starts, and decide what a stock is worth. Act only when the price is far below that.
What is the manic phase?
The manic phase is the danger zone. Euphoria drives prices past what businesses earn. Everyone calls it easy. That is when Mr. Market overpays you. Sell into the mania to lock profit while the mood runs high.
What is the depressive phase?
The depressive phase delivers the bargains. Gloom pushes prices below sound value, and fear rules the headlines. This is where you buy quality at a discount. Buffett put it plainly: be greedy when others are fearful.
How to use Mr. Market's swings to your advantage
These mood swings that create bargains are your edge. When gloom hits, buy quality. When euphoria hits, sell. The manic-depressive market is a feature, not a bug. It gives you chances to buy low and sell high, so keep cash ready and the nerve to act.
What does voting machine and weighing machine mean?
Graham called the market a voting machine in the short run and a weighing machine in the long run. The vote counts emotion. The weigh counts value. You profit when you trade less on the vote and more on the weight.
In the short run the vote decides price. Crowds push it up and down on sentiment, not on facts. That vote is the manic-depressive market doing its mood swings. It is noise, not a signal.
In the long run the weight wins. What a business actually earns slowly becomes the price. The manic phase fades, the depression lifts, and value reasserts itself. That is why you can ignore any single daily quote.
So Mr. Market's daily price is a vote you may skip. You buy when the vote is low and the weight is high. That weighing machine is the edge that survives every mood swing.
