1. Strong Open Driven by GST Optimism & GDP Data

Markets are poised to start Tuesday on a positive note. The Nifty 50 is expected to open above its previous close of 24,625 as optimism builds around potential Goods and Services Tax (GST) cuts being discussed at the GST Council on September 3–4. Gift Nifty futures are trading around 24,749 points.
Further, stronger-than-expected GDP growth has buoyed investor sentiment, especially as indices rebound from a recent losing streak.
