In terms of thinking about market valuations, think, do I care? My goals are 10, 20 years from now, not now. If you have shorter-term goals, you should be aware that market valuations fluctuate wildly.
The truth seems to love the small print.
History depends on who is telling the story.
Arbitrage human nature. It's not going to change any time soon.
If you are an investor who's retired and hopes to live off the income that your portfolio is generating, then we would focus just on the dividend yield.
If you have a 401(k) at work and you don't use it, it's like literally walking by buckets of money every day,
If you're an investor who wants a little bit more from the capital-appreciation side of things, but still likes this concept of getting 'paid by the company,' then we would tell that investor to pursue shareholder yield.
If you're indexing to the S&P 500, you're buying the most expensive names in the market.
If you look back to the most spectacular blow ups in history, you can always tie them to a couple things: They were extraordinary complicated strategies that maybe even the practitioners themselves didn't understand, and they were overleveraged.
The average investor does significantly worse than a simple index... It's literally because of the way our brains are wired.
