Quote from Specterx:
I'd like somebody to show me some data proving that the difference between the 10-year bond yield and the SPX dividend yield has historically been a good predictor of stock market returns. Just look at the first chart in that article: stocks were supposedly extraordinarily expensive in the early 1980s (after all, they weren't yielding much compared to bonds!) but of course those years were a historic, once-in-a-lifetime buying opportunity, and this should have been obvious to those using common sense and Shiller PEs. The chart literally shows completely opposite readings in 1932 and 1982, two genuine generational lows. It's worthless crap.
On a straight theoretical basis these are different asset classes with wildly different risk and return profiles. It's certainly possible - even likely - that the returns on stocks will be higher over the entire lifetime of the 10-year bond. That is, higher than 2.4%/year or whatever, nominal, not compounded. That is over 10 years from current prices and says absolutely nothing about whether there'll be a 50% decline somewhere along the way, etc. It doesn't say anything about your real returns which could be deeply negative. Not my idea of a generational buying opportunity in stocks.
