Romanticizing that you are a contrarian when you are indistinguishable from consensus can’t be good.

The quote above comes from Adam Parker, Morgan Stanley's U.S. equity strategist and director of quantitative research. He set the Internet abuzz this past weekend with a research note in which he wondered why he keeps getting questions from money managers about why stocks rose in the past two months and what will happen next.
