Investors are an emotional crowd, especially when US equities, measured by either the Dow Jones Industrial Average or the more accurate S&P 500 index, have just hit all-time highs. I am not sure who first remarked that market behaviour is motivated by two competing emotions, fear and greed. But I do know that Albert Einstein claimed that “Three great forces rule the world: stupidity, fear and greed”.
Some of the macroeconomists that I have learned not to ignore, like Lawrence Summers and Martin Wolf believe that the outlook for the US economy under President Trump is at best uncertain, and that the recent equity market highs are a “sugar rush”. I recognise that some of these critics have major political differences with the new Administration. But many others, like the perceptive and apolitical John Authers, are also very concerned about equity over-valuation.
So, are investors being “stupid”?
That does not make the models the only source of wisdom about future asset returns. Far from it. They are good at avoiding some of the behavioural mistakes that investors are known to commit, such as a tendency to dislike losses about twice as much as they like gains. But human beings may be better at recognising when the investment climate is about to change because of policy upheavals.
In this article, I will try to eliminate emotion by reporting some recent results from the suite of economic and financial models built by Juan Antolin Diaz and his team at Fulcrum. The results are somewhat encouraging: recession risks in the US are low and the over-valuation of equities is less clear cut (on some measures) than is sometimes supposed.
In the short term, however, there are signs that the most active short term traders in the market may be heavily exposed to equities at the present time. This could make the market vulnerable in the short term to policy shocks that cannot be incorporated into the models, such as a major outbreak of trade protectionism. Read more
