There's also the fact that this dip is still significantly higher than the previous dip visible in that screenshot, which likely just means there was a spike caused by the Christmas season and things are returning to normal in January.
Basically this.
Also, the "dip" started across the 18th and 19th. Not the minor fluctuation in the 16th.
And GW being a UK traded stock is part of the FTSE 100 index. Yet strangely enough that fluctuation and dip also aligns with NASDAQ and the S&P 500 that have nothing to fucking do with GW stocks.

Just like how people on youtube with clickbait can't spend 2 fucking minutes to look any of this shit up before spouting nonsense, I guess people on twitter or whatever can't either, and then some people just parrot it again without looking to see that none of that was GW specific unless somehow female custodes affected the global economy.
So fucking retarded... it really doesn't take some genius financial experience to look this shit up.
also, to show how this is even more fucking retarded
The preview where female custodes were shown didn't happen until AFTER trading had already been long closed(4:30pm GMT) in the UK on a fucking Friday. No one was watching the preview stream and suddenly panic selling huge amounts of stocks unless it was minimal after hours trades, because the market wasn't even fucking open. Again, it's so easy to look this shit up.
edit again: and the company was doing so fucking poorly I guess that they declared a 1.10 pound dividend per share to be paid in May.
And also claiming that it was planned or whatever so the board could buy or panic sell is also stupid because that has to be done with public statements, and it was just the CEO buying 124 shares(so not much) with the dividend reinvestment plan
