EPF only buy low sell high never do the opposite becoz they have shares at so many GLC comp. If you did observe long enough, when the stock price is underperform like Mas they literally stop "selling n buying". So YinG, because it is higher price than what EPF bought previously so they are taking profit. You nvr know when the share will drop. that is just how they play the game for yrs. ASBN all doing the same thing too, that's we get 5% 6% div from EPF n ASBN yearly tho so they are not stupid.
