To start 2012, the benchmark had an earnings multiple of 13, the lowest since 1990 and below the 80-year average of 15, according to Bespoke. It would take a move back to 1,484 to get the benchmark back to this long-term mean P/E.
The price-to-book ratio is 2.05, below the average since the late 1970s of 2.43. To get back to that average P/B, the benchmark would need to increase to 1,491.
One more valuation—dividend yield—points to above 1,400, argue the two strategists.
