As we enter the penultimate day of the expiry of derivative contracts for September series, we are likely to see an optimistic opening to the trade as cues from the Asian peers are supportive. The SGX Nifty is trading with gains of 56 points at 10,134, indicating a cheerful start to the day. However, we maintain our cautious stance on the markets as volatility is likely to remain elevated ahead of the expiry of September derivative contracts as also the outcome of the US Fed meeting. We would advise traders and investors to remain selective in stock picking.
