Certainly seems like NDX/NQ are the driving force behind the continuation of the upside, speculators have flipped to being long Nasdaq and remain short SPX. Next obvious resistance is not that far ahead though. With inflation continuing to decline, it is unlikely for the FED to continue to raise rates, so as far as rates are concerned, we have probably peaked or are close to it. Trend-following funds have no choice but to go long, hence the flip from being sellers of tech to being buyers IMHO.
