I worry about the signs of froth in the market and among some behavioral measures of investor sentiment; not to mention traditional valuation metrics that are historically‑stretched. This is not an environment in which greed should dominate investment decisions; but instead one for discipline around diversification and periodic rebalancing. Momentum can power the stock market beyond fundamental supports; which is why John Maynard Kenyes’ view from the 1930s remains oft‑quoted: “Markets can stay irrational longer then you can stay solvent.”
