Yesterday, as the S&P closed above 2,000 for the first time, mainstream media pundits were trotted out to proclaim that either “stocks are ‘fairly’ valued” or “stocks are cheap” and the “money on the sidelines” must come in now. Aside from the ‘idiocy’ of the last comment, we thought BMO’s Jack Ablin’s comments were of note. “Valuation is the market’s biggest headwind,” he wrote, adding that sales “have to catch up” for stocks to sustain the rally.
