Something happened to stocks for the first time ever on Monday

Markets have made a number of rare moves since the US presidential election last week.

The Dow rose to new highs for four straight days, and Treasurys surged to 2016 highs, for example.

And on Monday, more than 300 issues on the New York Stock Exchange advanced to new 52-week highs, and more than the same number of issues fell to new lows. It happened for the first time ever, according to Ryan Detrick, a senior market strategist at LPL Financial.

This is part of what technical analysts call the Hindenburg Omen. The idea is that the number of stocks setting new 52-week highs should normally outnumber those setting new lows (and vice versa,) reflecting some uniformity and clarity of direction. However, a wide dispersion between new highs and lows is not seen as a good market indicator.

The high number of stocks making new highs and lows at the same time showed that “this is a confused market,” Detrick wrote in a blog post Wednesday.

What it does not signal, however, is the potential crash of a normal Hindenburg signal.

That’s because, Detrick said, the sudden bond market sell-off last week hit other assets that were linked to fixed income. “Looking at common stocks only shows a much different backdrop, as on Monday common stocks made 319 new highs, with only 21 new lows,” he said.
