Charts always draw insights in an ideal form but dynamical events like CPI data, GDP growth rate, FED policy shouldn't be neglected and yes Indian market yet to be corrected in comparison with US but some good news like Inflation reduction and Manufacture sector growth Y-Y can force index to soar.

Unpredictable here means that it doesn't follow US market which is not the case with the Indian market. Also it's just an opinion. We surely can never say anything.

Indian market is overvalued and sought a correction due to covid. Even if lockdown didn't happen, the big fall was inevitable either ways. Even at this levels considering all the data Indian market still follows US market and easily predictable. All said the next year is gonna be China's undervalued market.
