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.
