Investors have to remember: corporate profits are going up, but stocks are going up faster. How can that continue indefinitely? Investors can only earn what companies themselves can earn; the government or the markets themselves don't kick anything in. How can you get anything more out of a farm than what it grows?
Warren BuffettIf you donโt feel comfortable making a rough estimate of the assetโs future earnings, just forget it and move on. No one has the ability to evaluate every investment possibility. But omniscience isnโt necessary; you only need to understand the actions you undertake.
