My 2c.
Daily close below 1992 SPX and more downside likely.
Another one to watch is AAPL, it's sitting right on 20MMA (108), the way I measure trend cycles it's uptrend is now over, just a matter of time before it hits new lows. Basically, it's unlikely to breach it's ATH before we see continuation of downtrend in AAPL. And of course once AAPL starts declining so would Nasdaq.
