Just for me personally, this has meant a return to my early roots as a 1990's investor where you have to put in the work to pick the best opportunities. The S&P500 index is no longer defaulting to the top of the list, because it now contains a lot of overpriced equity from all the other investors that have been crowding in to index funds for a decade and are still sitting there not selling. It isn't the worst option, but there is real competition again, including fixed income.
There is also the element of waiting for bargains, but that could still be a long ways off.
Philosophically, there is nothing magical about the S&P 500 index. It is basically a large cap strategy. Which is fine, of course. But for example, the S&P 500 equal weight index has a PE of 17 vs. 22 for the standard index. Nasdaq equal weight has a PE of 22 vs. 29 vs. the cap weighted index.
I'm not saying to chase PE, but the higher valuations are concentrated in the large caps at the moment.
PE was around 15 in 2012 and 17 in 2013 so probably not a lot of complaining about high PEs back then, and they would have been lower on a forward looking basis.
Most cite the Shiller PE, which was ~21 in 2012. And plenty talk about how this was "unsustainable", crash imminent etc.
But maybe this time it's different? Or was it different that time but not now...? I'm not sure.
aka don't time the market...
I don't think anyone in this thread was talking about jumping in and out of the SP500 index fund (aka timing), my main point was to look at the broad landscape of investment opportunities and pick up diversifications to hedge against the fact that VOO (P/E 21.2, yield 1.59%) has real competition, like a 12-mo gov bond yielding 5.4%...
Long term equities will/should perform better than bonds (unless we turn into japan) but right now there is a resetting going on to wash out the excess of pandemic related spending and a decade of zero rates and QE.
As EV says there is competition and you can be paid to wait.
In the last five years to today, sp 500 earnings are up 6.8% annually, sp500 returned 8.6% annually + dividends, and the 10year UST (the primary discounting factor) went from 3.1% to 5%.
Same pattern is true for the last 35 years when rates started coming down from the 70s inflation era....sp500 earnings grew 6.3% annually, sp 500 returned 8.1% annually plus dividends, while the 10yr ust went from 8.7% in 1988 to 4.8% now.
Earnings ultimately drive the long term direction of the stock market but rates are instrumental to the difference between the variance between growth in earnings and growth in values.
And right now we are in a rising rate environment that anybody under the age of 60 hasn't experienced.
The question is whether rates go higher and sustained longer. Personally, I think they can go higher from here but will settle in at the 3.5-4% range after the Fed gets its way in two'ish years timeframe. I don't feel/think this is like the 70's but who knows.
As said above, earnings have to grow faster, market has to fall further sooner or stay where it is for longer, and/rates have to fall sooner/faster/farther.
I am not saying sell your equities, just appreciate the landscape and what are likely outcomes in near and intermediate terms. Long term it should be fine.
You tell me which is the more likely outcome.
