$NVIDIA (NVDA.US)$ so qqq usually follows nvdas charts to the t but since its dropping now its apples chart to the t nvda dropped over 15 dollars in 2 weeks and qqq at highs cause apple is at highs how does it always seem to pick only 1 stock to follow and it doesn't matter if the rest are down or already down just weird i usually watch qqq follow nvda the same way till now when it sucks so it follow apple but if apple drops and nvda goes up it will almost completely copy its chart exactly until it actually drops then will switch to the next one that goes up even if most are dropping or are down basically saying it only drops if they all drop.
