Volatility will remain the theme given the current uncertainty in global markets amid renewed concerns over the likely interest rate hike by key global economies in the near term. While markets may start flat to negative, recovery in the Gift Nifty index could aid the sentiment in intra-day trades. If both the Dollar index and US treasury yields continue their ascent, the rupee may come under pressure and we may witness further global fund outflows from domestic equities. Caution will also prevail due to spiking global crude oil prices around $90 a barrel, while investors will closely watch the statement from HDFC Bank which had last week warned about widening bad loan ratios and narrowing margins after the merger with HDFC. Technically, Nifty’s biggest support for today’s trade is placed at the 19607 mark.
