A few days ago, the 16th of November, this post was put out for the Nasdaq100 index.
Continuing the conversation about the Nasdaq100 development, the big question is IF the index now will continue to follow the 2007 route (see graph below), or - if it will drop straight through the floor (red support line) and outpace the 2007 into 2008 downtrend.
The two red dots marked in the dark graph below shows a fall of 20% in 56 tradingdays. For the present red graph to follow this map more closely, the index should preferrably bounce in the beginning of this week, for thereby to start the real - 20% drop about Thursday the 29th of November to last 56 intradays.

Only time will show if there is some validity to this 2007 into 2008 map...
If now taking this a step further adding the 1973 and 1987 for the DJIA and 2000 and 2007 for the Nasdaq100 index, and comparing it to present levels for the Nasdaq100 index - this is what you got:

The red dots marks the low point of its respective downtrends.
Calculated from Fridays close, you will find that the DJIA development in 1973 is 2.7% lower in 36 tradingdays. The DJIA in 1987 is 21% lower in 34 tradingdays. The year 2000 for the Nasdaq100 index equals 10% lower in 4 days, and the Nasdaq100 in 2007 is 20% lower in 56 intradays.
