Readers should be aware that short selling is banned in 975 financial stocks in the USA. Yet, the Dow fell by record percentages (so did the S&P and Nasdaq). Then, who was selling ? The nswer is obvious: markets decline when investors / holders of stocks decide to sell while there are few people left to buy. Short selling is a convenient scapegoat.
It seems fair to say that the Nifty will open today, below 3800 support. Below 3800, there is no technical support till 2000. I am not suggesting that the Nifty will fall to 2000. It should not, and will not. My point is: now the market will have to determine its support levels on its own. It can stop wherever it wants.
This is not a good time to trade. Wait for stability, for volatility to come down. Support must emerge.
