Trade setup for Wednesday: Top 15 things to know before Opening Bell

Key Indian indices fell on September 22 as concerns over the second wave of virus infection weighed down investor sentiment.

Sensex closed 300 points, or 0.79 percent, lower at 37,734.08 while Nifty ended at 11,153.65 with a loss of 97 points or 0.86 percent.

BSE Midcap and Smallcap indices closed 1.70 percent and 1.61 percent lower, respectively.

"The second wave of infections in Europe and other countries has raised fear of re-imposition of lockdown. In such a scenario, markets will continue to take cues from global peers," said Ajit Mishra, VP - Research, Religare Broking.

"Having said that, we may see a pause or a bounce after the recent fall but the bias would remain on the negative side till Nifty holds below 11,400. Traders should focus more on risk management as we expect volatility to remain high due to scheduled derivatives," Mishra added.
