The S&P is substantially overvalued on 18 of 20 valuation metrics, with the only exceptions being free cash flow (helped again by depressed capex), and relative to small caps/bonds - the Fed's favorite indicator - where yields remain depressed thanks to the Fed's failure to stimulate wage inflation for nearly 9 years.
