After five weeks of declines, Analysts expect a short-term rebound in Nifty on August 4, with support at 24,450-24,500. But resistance at 24,660-24,780 could cap gains. Analysts warn of fresh selling if Nifty fails to hold above 24,450, with downside targets at 24,200 and 24,000. Strategy: Sell on rise unless 24,784 is breached on closing.
