$GOOG and $TSLA are my two Mega Caps that are still looking like this may come down further.
$GOOG has rejected at its 200 Day MA on its 1hr chart above and this isn't a bullish sign and while $AAPL etc have 3 very clear ABC wave counts for its Wave 4, $GOOG has only 2 waves so far, meaning Wave C of Wave 4 has not come in yet.
So this would not be my first preference to buy right now from the Mega Caps but if it can come down lower as shown, this is certainly more attractive.
