Was orchestrated in my opinion to let the shorts close with a profit and for longs to load up on the cheap because they know a bid is about to drop. The drop was way overdone on information that was 99% already known and that FT article read like it was written by a kid on work experience.
Seen it before in a takeover approach, company said they would suspend at end of month, total nonsense. They were just hurrying up the bidder to make an offer. Offer was made, guess what, no suspension.
