Seems like they have sold almost all of their shares. So I don't think SHL will come down in the near future.
The other comment I like to add is regarding Pathirage purchasing of shares.
Its not only Pathirage, Dammika also has been purchasing shares of his company. He bought 1mn @ 33.50 when it was falling from 38.
I think Pathirage is clever, purchasing from Carsons, who made the price bellow the IPO price.
