Where The Bear Stops?

Markets with an early plunge today as the Great Unwind continues. The relative ease of the generational gains which started in August of 1982 have met a few road blocks, the dot com break and 911. This stock market is experiencing what every commodity trader learns to trade around, the occasional death dive. The breaks usually fall until they reach the 50% retracement level of the entire bull or bear run, which in this case can be measured over 26 years. The crash of October 1987 reached 1616 or a 41% decline from 2746. The great bull run of the last century saw its last leg,( the first leg started in the 30's), begin in August of 1982 with a low 769. The rally reached a high 14198 in October of 2007. A 50% retracement lands at 7484. Today's inter day low as of this post is 7882. Close enough?
