This historical review of the Dot-com crash is instructive to compare to price action now to then.
As noted in my last NASDAQ idea (just posted - see link below), the MACD diverged strongly in Feb-Mar 2000 on the way up before the Dot-com crash began.
MACD is rising with prices now and has not shown any divergence.
This again means the current drop is just a correction and not the start of THE bubble burst/crash.
New highs are coming after the correction is over.
