We'll see if this drop in $AMBA post earnings turns out to be a shakeout or something more serious. So far it has sliced through both its 10ema and 21ema. It has held the 21ema since 7/6. I think its worth noting that $AMBA traded straight down to the prior ascending trend line that served as resistance from 6/9 - 8/12 and then bounced off of it. This line proved to be support on 8/18. We'll see if it holds today.
