In the long run: business performance

Over years, a price tracks the actual profits the business produces. A company that keeps growing earnings tends to see its price follow, regardless of the daily chop.

In the short run the market is a voting machine — popularity contest; in the long run it’s a weighing machine — it weighs real earnings. Trade the votes and you’re gambling; own the weight and you’re investing.
