Why do people specifically check SGX Nifty before markets open in India

Hey there I am new in trading.
I have noticed that people in India check SGX Nifty before Indian markets open in India.
People predict Gap Up opening and Gap down opening on the basis of SGX NIFTY.
So my question is Why does SGX NIFTY get so much attention compared to other world markets.
Thank you!

SGX Nifty is Nifty’s global derivative contract which trades for 24 hours on Singapore Exchange. People pay more attention to it simply because SGX Nifty’s price already has counted for any news or event.
