Premature to say what? It's an observation based on past earning reports that preceded earning calls.
Even the peak 7% post earnings call (now 5.7% and probably a different number by the time I hit "reply") is a relatively small move compared to past 4 quarters and that's without even taking the stock split + dividend increase into account.
Sure, tomorrow it can get to 15% but all I can compare it with right now is the past price action post earnings.
Exactly, which makes it the smallest post earnings price action in the past 4 quarters (last one was also smaller than the 4 that preceded it iirc). And today was the only one that had stock split. It'd have probably been even less than 5.5% if it wasn't for that.
Not saying it's not going to beat the market in years to come but it is slowing.
