It could have been a trade that helped them through the 3% barrier.
Likely been accumulating over days....
They can trade in many various ways to accumulate size:-
A) leave an order in the block MTF’s such as Posit, Turquoise or Liquidnet
B) leave a block order with a broker of choice like a UBS with a limit price - example buy up to 1m shares at a limit of 800p in tranches of 50,000 or greater
C) give a broker of choice a live order to buy in the central limit order book (CLOB) in this case SETS and/or Euronext again with a price limit and a volume limit (VWAP)
