IPO subscription of ASTER DM HEALTHCARE LIMITED has decreased

Why the total subscription of “ASTER DM HEALTHCARE LIMITED” has decreased? On Wednesday it was showing 2 times oversubscribed on BSE and NSE but today it shows only 0.3 times.
Why did it happen?

Reason may be 1. Many of the applicants cancelled the subscription
2. see the attachment

That’s true. Because the 7 days ago the gray market premium was around 70-80 Rs. But why did this happen? I haven’t seen any negative news and its leading booking managers “Kotak Mahindra Capital Company Limited, Axis Capital Limited, Goldman Sachs (India) Securities Private Limited, ICICI Securities Limited, JM Financial Limited and YES Securities (India) Limited” also has a strong background.
So should I avoid this IPO and purchase after listing?

Its better to avoid / i am also not subscribing it , i think some more correction will be there on the market & also after correction , there are lot of stocks , one can buy.
In my experience , Grey Market premium are good indications than “FUND MANAGERS”. Again, if HNI portion is well subscribed , will be a good risk /reward one.
