My speculation is that such institutions may well have instructed a broker to accumulate as many Mol shares as are offered on the market at the lowest price.
So broker buys many thousands. And when selling dries up places small sell orders to bring price down.
If surge of buying occurs that's OK. Institution sells a small part of overall holding at a profit.
If "small time sellers" wish to unload they must sell below previous selling offer. A lowish one placed by same institutional broker.
The solution? Many buyers moving in to wipe away broker sell orders.
This process can only work if accumulators are working together, or there is a sole accumulator and "selling dribble" continues.
