Market Overview - The A-share market continued to rebound with reduced trading volume, with the Shanghai Composite Index returning to 3900 points, and nearly 4600 stocks in the green.

The overall bull market logic remains intact, supported by structural prosperity and ample capital. Key sectors to watch include dividends, precious metals, large financials, and AI [9]. - **China Galaxy Securities**: The market is expected to experience a phase of cautious sentiment due to external trade uncertainties. Focus should be on sectors with strong policy support and earnings certainty, particularly dividend stocks and large consumption sectors [10]. - **Orient Securities**: The market is likely to remain in a range-bound state, with a balanced approach to sector allocation. Attention should be given to semiconductor equipment, AI, and coal sectors, which are expected to perform well due to price expectations and seasonal demand [11].
