EPF bought millions of share in all telcos which we saw price jump just before New Year. Supposedly, OPCOM shares should rise to complement that move by EPF. And market was informed on OPCOM secured an order worth 25mil from Axiata. I was surprised OPCOM shares fell.
Do you have any idea why?

OPCOM share price could not go up because there are many people wants to sell their shares. At the same time, many people waiting to buy OPCOM at lower price. What happen today is simply people doesn't want to keep OPCOM shares. You can see this in bidders/sellers spread.
