Klement on Investing • 5 implied HN points • 17 Dec 25
💰 Finance Portfolio
  1. Over nearly a century U.S. small-cap stocks beat large caps on average, but that average hides very long stretches of underperformance that can last decades.

Erb and Harvey are at it again

Klement on Investing • 3 implied HN points • 16 Dec 25
💰 Finance Portfolio
  1. Gold has had a huge rally, rising more than 50% in about ten months and breaching record highs around $4,000/oz, which has reignited investor enthusiasm and big price forecasts.
  2. Academic analysis says gold has not been a reliable inflation hedge over typical investment horizons and that high current prices tend to predict poor future real returns, so lofty prices imply limited expected gains.
  3. The rise of gold ETFs created a steady, structural demand that lifted prices, and the only realistic way to trigger much more demand would be a regulatory change letting commercial banks hold gold as reserves — something that looks unlikely.
