Market again took a beating on Monday, with the benchmark BSE Sensex crashing over 551 points to 27,561.38, its weakest closing in over five weeks, on concerns that stricter norms for participatory notes may hit foreign investments and a major slump in Chinese stocks.
The NSE Nifty also dipped below the 8,400-level. Market slumped amid fears that the government may accept Supreme Court-appointed special investigation team (SIT) recommendations of stricter norms for participatory notes (P-notes) on markets, equity brokers said.
However, finance minister Arun Jaitley's statement during the market hours that the government will not take any "knee-jerk" reaction that will adversely impact country's investment climate failed to lift the mood.
"No such step would be taken which could adversely impact investment sentiment in the country," he said.
A sell-off in other Asian markets with over 8% plunge in Shanghai on worries that the Chinese economy is heading for a sharp slowdown added to the rout.
The 30-share index commenced lower and dipped below the 28,000-mark to touch a low of 27,529.57 before ending at 27,561.38, fall of 550.93 points or 1.96%.
Monday's closing was the lowest level since June 19, when the index had closed at 27,316.17.
Also, it is the second biggest single-day fall since 660.61 points plunge on June 2.

In broader markets, mid-cap and small-cap indices closed lower by 1.38% and 1.07%, respectively.
