The Nasdaq broke support on a line with its 1999 peak. A break below the previous 3042 bottom would likely lead to a final bo

ttom somewhere in the 2300-2900 range, 1999’s large trading range. To the upside, we want to see the Nasdaq get back above 3250, a small downtrend within a downtrend, then 3500-3521, its previous bottom and main downtrend line. If the index can recover anywhere above 3000, it could form a rectangle between 3000 and 4300. Also, there is a gap at 2900 that could be a downside lure here.

The S&P 500 broke its 1994 logarithmic trendline at about 1350, a very important level. The break of that line, which was briefly pierced in the 1998 sell-off, could carry the index as low as 1200. Hopefully, the index can recover back above that line quickly, as it did in 1998. The index also took out 1340, its April bottom. The S&P could find some support around 1300. To the upside, first resistance is at 1340, then 1350 and 1380.

The ISDEX again broke support at 650, the lower end of a 200-point trading range, and proceeded to take out 600. Next up is the May low of 560. First resistance is the ISDEX’s downtrend line at about 675. The Dow broke its April trendline at about 10,400 a day after piercing it, and also broke critical support at 10,200 today, the April low. The index could be headed as low as 9,500-9,700.

So how much lower could the market be headed? Since bear markets tend to end in October, hopefully the answer is soon, maybe as soon as tomorrow or Monday. But since the S&P broke its all-important 1994 logarithmic trendline, we should at least take a look at where the 1994 linear trendlines are. Those numbers are at about 9500 on the Dow, 1200 on the S&P, and 2000 on the Nasdaq. Also in those charts, look at the 1984 trendline, the main trendline of this bull market before 1995; we could drop a long way and still be in a primary bull trend. Also, we added the 1998 trendline to the Nasdaq to show how “vertical” its advance had gotten. And finally, we should point out that the break of the Dow diamond pattern that we’ve been covering could give that index downside to 8600 or lower. Again, all just speculation, with a hope for a quick ending to the sell-off. The indexes are as technically oversold as they have been at any time in the last three years, but that doesn’t mean they can’t keep getting more oversold.
