While I don't know if the drop is related to this incident or not, the video was wildly spread through social networks (at least in Europe) and even becoming a meme now. Even some news commented on it (local). Still no idea if it really affected the stock price, but it is 2 days now and people are still talking about it in these necks of the woods.
Drop was something like $1 per share which from ~$56 to ~$55.
Where 3 months ago Coca Cola was trading around $50, year ago Coca Cola was trading for ~$45 per share.
That was totally meaningless event, it did not drop in a way I would start buying. There is no real consequences for Coca Cola, maybe some day traders lost money selling for $56 before that event.
There was a $0.42 dividend priced in on Monday open since Monday was the quarterly ex-dividend day for KO, so maybe half of that is from Ronaldo, but that is not verifiable so … shrug
Take a look at the company's stock price over the last year (KO). This sort of drop is indistinguishable from random market fluctuations as far as I can tell.
This pretty much sums up the press when it comes to investments or even crypto. The tiniest blip equates to the sky is falling (or fire sale!). Zoom out and it's nothing.
