Mean Reversion: Index Risks & the ‘M7’

In the game of asset speculation – mean reversion suggests that over time an asset will eventually return to its average price if it drifts or spikes too far from that average level. If applied, it can often help you avoid paying too much. My thinking is the S&P 500 has now drifted too far from the longer-term mean. History has always told us that inevitably prices will mean revert. This post explores the potential risks to investors if simply choosing to passively invest via the benchmark Index. Look no further than the so-called “Mag 7” – which constitute more than a 30% weight.

Three Cheers for 5,000!

This week the S&P 500 closed above 5,000 for the first time. Another milestone as we climb the ‘wall of worry’. Over the past 100+ years the S&P 500 has averaged capital gains of ~8.5% per year plus dividends of ~2.0%. That’s a total return of close to 10.5% (on average). If you compound 10.5% per year over 20 years (i.e., ‘CAGR’) – that’s a 637% increase. But as we know, the pathway is rarely smooth. Some years the market may “add 20%” and others it could give back a similar margin (or worse). And we saw this happen recently. However over the long run – markets will rise more often than they fall.

Powell Won’t be Bullied

As we started this year – I felt the market was getting ahead of itself. Not only was the tape approaching an overbought zone – it also assumed as many as six rate cuts (possibly seven) before the end of the year. What’s more – it also priced in that earnings per share (EPS) would grow 12% year on year. It felt like a contradiction. For e.g., either the economy was reeling and needed (emergency) rate cuts; or the economy is expanding strongly (supporting earnings growth)? Today Fed Chair Jay Powell pushed back on the former. Markets should not expect rate cuts as early as March… stocks didn’t like it.

Will Earnings Deliver on the Hype?

Q4 2023 earnings are starting to hit the tape. From mine, if the market is to continue rallying – it’s less about inflation and the Fed – it’s whether corporate America will deliver on 12% earnings growth in 2024. Coming into earning’s season – my view 12% felt ambitious – given the slowing economy and relative health of the consumer. This post talks more to the concentration in the market – the relative influence from NVDA – and why diversification will be key this year.
