Remember one thing, ur cost will forever be ur cost. So for example, u r holding 10,000 units on last Friday (9/10) before the ex-date, which is today (12th Oct) you will be entitled for the bonus issue even if u disposed today. On tmrw (entitlement date) you will be issued with 5000 units of new share and the price will be readjusted. So, usually 'double' bonus could happen on the issuance date when the price is adjusted and people goreng up again. Hope tomorrow up-up to all who r holding it.
