Nifty Declines: As worse as it could get. For D-street investors, the statement is perhaps the best depiction of the current movements in the domestic stock market. NSE Nifty has now breached the key 22k support level, where several market players had placed their hopes. Benchmark indices are now down by around 15% from their 52-week-high. Last week alone, markets declined by 3%, with almost all sectors trading in the negative territory.
