Indian markets have come under pressure in the last four sessions with their global peers gauging the impact of Coronavirus on world growth after fresh cases of infections and deaths were reported outside China.

Sensex which had gained nearly 0.16% or 70 points on an year-to-date basis till February 19 has entered the red zone due to concerns over global growth in the wake of rising cases of Coronavirus outside China.

Siddhartha Khemka, Head, Retail Research at Motilal Oswal Financial Services said, "With the outbreak spreading to other countries, investors are increasingly concerned that there could be a much larger impact on the global economy.

Ajit Mishra, VP - Research, Religare Broking said, "The recent global developments indicate that the coronavirus could escalate into a pandemic, which is taking a toll on markets across the globe including ours.

The main reason behind such a big crash was the announcement from Centers of Disease Control and Prevention (CDC), which warned of a broader disruption if the Corona virus threat spreads to the US.

The majority of cases and deaths remain centered in China, but the rapid spread to other parts of the world has spooked markets and raised fears that it will hurt the global economy.
