You don't actually make any extra profit because your main share has depreciated after the ex-date. Only way you can make a profit when you sell your rights without subscribing is that people goreng the rights up and the main share up.

Either way, even if you don't sell your rights, at the end of the day you still will get extra Maybank shares when you subscribe to the rights.

Worse case scenario is that Maybank shares start to drop after rights issue and your share prices depreciate below the ex-right price.

But if you don't intend to subscribe but still want to hold the main shares, then sell your rights during the window.

If you don't sell it the rights and you don't subscribe as well, then you will lose big time.

I understand from my broker that you do not have to wait for the form to arrive if you are in the hurry to sell ( maybe better price on first day ). Just arrange with your broker to do so ( the one you that you bought  yr TMI shares from ). The system has your info.

By the time, the postman delivers  the form to you, it could be on the very last few days.

In between, you may lose some sleeps while waiting and the price is dropping day by day.

The best is to check and arrange with your broker . I believe there  is also  some  odd lot, so got to trade in odd lot mkt.
