Such a configuration happened just 16 times in the past, and never in this century. In fact, the last occurrence was in 1988! Consider the graph below, which plots the closing prices of the NASDAQ between 1970 and 1990. With the vertical lines identifying the dates of these events, it indicates that 12 of these days came during the market decline of 1973 1975. The other four are associated with the drop in 1987.
These findings require caution before applying history to current projections, simply because of the long time involved. It is reasonable to expect behavior to change over this period just as the technology of trading is not the same now as then.
Nevertheless, in that earlier period, on the following day, the NASDAQ moved higher on 12 of those 16 days, whereas the DJIA and the S&P500 scored only ten advances.
DJIA 2.59 percent
NASDAQ .62 percent
S&P500 2.05 percent
