Market Cycles And Why The Bull Isn’t Dead

There is much debate as of late on the current market cycle. Is it a bear market? Maybe. But what if this is just a correction within a 40-year-long secular bull market cycle? It is a question posed by Jacques Cesar previously.

“The cyclical bull started in late March of 2020, after the market plunge sparked by the initial outbreak of Covid-19. The secular bull began way back in 1982, as equities shook off a vicious 14-year slump that more than halved the S&P 500 index when adjusted for inflation. There have been some notable cyclical bears amid the current secular bull, including the 1987 crash, the internet bust, and the global financial crisis.”

Before you dismiss the notion entirely, his claim has some credence.

For example, as shown, valuations remain high by historical standards. Valuations in a bear market cycle should mean revert and forward return expectations.

Furthermore, the detachment of the stock market from underlying profitability has been a constant companion since 1980. The lack of a mean reversion in profits is a concern.

“Profit margins are probably the most mean-reverting series in finance, and if profit margins do not mean-revert, then something has gone badly wrong with capitalism. If high profits do not attract competition, there is something wrong with the system, and it is not functioning properly.” – Jeremy Grantham
