Imagine you own a private business with a partner named Mr. Market. Every day, he offers to buy your share or sell you his. Some days he is euphoric and offers absurdly high prices. Other days he is depressed and will sell for almost nothing.
§ 02Key point
The key insight: you are not obligated to trade with Mr. Market. His mood swings are your opportunity, not your guide. If his price is too high, sell to him. If too low, buy from him. If neither, do nothing.

§ 05Key insight
The stock market is a voting machine in the short run and a weighing machine in the long run. Mr. Market votes with his emotions. Your job is to weigh with your analysis.

Want more practice on the Mr. Market mindset?
