What can we conclude from these observations? In fact, one may conclude that a relatively benign inflation rate up to 4% is positive for equities. Beyond that level, equities tend to struggle. Also, we have seen that PE multiples (thus valuations) decrease in inflationary cycles. It is of paramount importance to look at the debt structure of companies, their pricing power, valuation and returns on tangible capital. It will become key to look for high-quality companies that are able to increase their prices beyond the inflation rate. Also, a complete absence of inflation or even deflation (the Japanese scenario) is very detrimental to corporate profits, but this is not our central scenario. Our general conclusion is that it is extremely hard to define hard and fast rules with respect to the link between inflation and equity returns. The response of individual companies will experience a very high dispersion and should therefore be taken into account in a bottom-up stock picking approach.
I have several links to comprehensive articles and research that analyse the impact of inflation on equities:
- Warren Buffett: “How inflation swindles the equity investor”, Fortune Magazine, 1977. This is a very long article, written 33 years ago, but considering the content it is well worth the time if you would like to better understand the relation between inflation, interest rates, earnings, ROC, equities;
- Rolfe Winkler: “The inflation time bomb”, Reuters. This article looks at the connection between current debt and future inflation;
- Wayne Whaley: “What do rates rising from zero mean for equities?“, Trader’s Narrative
