That sounds reasonable, though I can't say how much so as I was not watching the trading during the day. My screen, had I been watching it, shows who is buying and selling by which "house". The last time we saw big volume, it was clearly one seller, which lead to that being very strong evidence it was the/our financier.
If you are correct, I would expect to see this selling contiue with the market opening tomorrow, and mostly by a single trading firm.
That said, I had noticed in recent days an abnormal build-up of bids from multiple sources at lower prices. I am not attaching meaning to that, just reporting.
Stay tuned. Meanwhile, none of this feels as if it effects the prospects for news, which is all that really matters anyway.
Happy Independence Day!
