The Economonitor is fond of technical analysis gobbledegook, and at this point it takes more than a Fibonacci retracement level or a bearish head-and-shoulders pattern to get his attention. But Mark McMillan has solid gold for us today:

A rare Japanese candlestick pattern was put in on Wednesday's close. Tracing back to last Wednesday through Friday, we showed an imperfect Evening Star pattern that was ominous, warning the uptrend was at an end. This Monday through Wednesday the pattern repeated but this was an even more powerful form of Evening Star, because of the doji star pattern on Tuesday. Tuesday's doji star was significant enough to suggest taking profits on long positions, or to put on a short position. That was confirmed yesterday.
We can not emphasize enough, the ominous nature of the double evening star, with an exclamation point on the doji star seen on Tuesday. In addition to that, Wednesday's candle was a bearish engulfing.

Are you scared yet? You should be:

We would not want to be long going into the weekend. Black Monday occurred in 1987.

"Wednesday's candle was a bearish engulfing", of course, has roughly the same semantic content as "colorless green ideas sleep furiously". But it does make for jolly entertaining reading.
