V.K. Vijayakumar, Chief Investment Strategist at Geojit Financial Services said there is risk-off in global equity markets triggered by a combination of economics and geopolitics.

The Israel-Hamas conflict continues to be a major headwind for markets. If the conflict lingers for long it has the potential to impact global growth, too, when the global economy is already in the midst of a slowdown.

In the near-term, however, the strongest headwind for the market is the stubbornly high US bond yields.

With the 10-year bond yield at near 5 per cent FPIs are likely to be in the sell mode. Sectors like banking and IT which constitute the largest segments of the AUM of FPIs are likely to be under pressure. This will provide opportunities for long-term investors to buy quality stocks, particularly in banking, at attractive rates, he added.
