According to this analyst the US stock markets were were already evidencing signs of exhaustion as very well demonstrated by the now 10 day series of lower closes in the Dow Jones. Well, by the close last night, the S+P 500 and the Nasdaq 100 indexes sure played catch-up. The Nasdaq 100 tumbled the most of all, suffering its biggest one day slide of the year. The index had closed on Tuesday at 22,001. It fell back to a low at 21,146 yesterday evening, before later closing 791 points lower, at 21,209. That close was below its 21 day moving average, in place then at 21,260. At one stage subsequent to that close, the Nasdaq futures were pricing a reopening today at below 21k. It is not quite that low just now, but  it is not currently pricing a higher opening. The indication on that is around 21,176
