The NASDAQ hit its major trendline last month and has since bounced off it. This last happened in 2006, where in the following 5 months it continued to drop just under 50%. And the first time it touched the trendline it dropped around 71%, 9 months after the touch.
History repeats itself, but not all patterns are the same.
With this in mind, based in previous evidence it would seem likely for a large drop within 3 months, if it continues a similar pattern.
We will just have to see how the market plays out and if there are fundamentals that will come into play to explain the market crash.
