They have twice posted a charticle with the the headline "Biggest Buy Signal Since 1985". That would have been a good headline to go with in March 2009, but now that the DJIA has rallied 6000 points it kind of seems a little pointless.
Anyway, the chart is a variation on the traditional bullish-bearish sentiment chart, with the idea that alleged record pessimism on Wall Street that the chart supposedly shows is actually a great contrarian buy signal.
My question to Business Insider is: does anyone there know how to fucking read a chart, because the one you posted shows a monumental breakdown in optimism among Wall Street analysts. Listen, I'll be the first in line to point out a positive divergence in sentiment or a contradiction in the bears' position, but this chart ain't it.
This chart show a bunch of rats jumping off a sinking ship. That's what I see.
