On January 2, 2000, Howard Marks published his first memo to garner any reader response, bubble.com, calling attention to excesses he detected in the market for tech and internet stocks. His newest memo revisits the subject of bubbles. Howard expresses his view that they’re more a state of mind than a quantitative calculation and describes bubble thinking as irrational, often underlaid by a widespread belief that ‘‘this time is different.’’ Rather than opining on whether we’re in a bubble, Howard lists the signs he sees today and suggests how you might think about them . . . just as he did 25 years ago.
