Cipla open price

Cipla close 836.8 par hua tha toh open 839.90 par kaise hua ??

Stock or even Index will not always open at the same price it closed at, it will either open higher or lower, depending on sentiment.

First of all cipla previous day close price was 836.8 …and it opened at 839.90 the next day… So it opened a little gap up.
