If the IPO is subscribed multiple times in retail, it doesn''t matter if you have applied 1 lot or full 2 lac application.
To increase your chances of allotment, apply through different accounts (your family members account). If IPO is going to be subscribed multiple times, you should only apply for 1 lot.
And in the case, the IPO is not even subscribed 1.X, you will get full lots that you''ve applied. But, it also means that the the IPO will be listed at discount price!
