I imagine that 1620 will have their own bills to pay and so will sell down small proportions of their holdings in various companies to cover their own cashflow requirements.
If they had sold 40% or more then I'd be worried about a leaky ship or poor results.
I'm happy that they're still in the top 4 and no significant change to their holdings.
