盘后播报（2.4）

Market Overview - The A-share market showed a strong fluctuation today, with the Shanghai Composite Index rising by 0.85% to 4102.20 points, while the Shenzhen Component Index increased by 0.21%. However, the ChiNext Index and the Sci-Tech Innovation Board Index fell by 0.40% and 0.98%, respectively. The total trading volume in the Shanghai and Shenzhen markets was 250.33 billion yuan, a decrease of 62.4 billion yuan from the previous day. Overall, the market sentiment was neutral to weak, with over 3200 stocks rising [1]. Sector Performance - The coal, gold, and dividend sectors led the gains today, while high-volatility sectors such as artificial intelligence, media, and telecommunications experienced pullbacks. Small-cap stocks underperformed large-cap stocks, and growth stocks lagged behind value stocks, indicating a preference for more stable investments [1]. Gold and Silver Market - The Gold ETF from Guotai surged by 4.24%. After two consecutive days of significant declines, gold and silver prices rebounded strongly, with spot gold rising above the 5000 USD mark and spot silver exceeding 90 USD. The rebound in precious metals prices followed a concentrated release of selling pressure, and the implied volatility of gold showed signs of turning upward again after a previous spike and subsequent correction [1]. Coal Sector Insights - The Coal ETF (515220) saw a significant increase of 9.07%, while the Guotai Dividend State-Owned Enterprise ETF (510720) rose by 4.29%. Indonesian officials announced that local miners have suspended spot coal exports to support prices, as current profit margins for miners are low. This suspension is aimed at avoiding default risks due to quota uncertainties, although long-term contracts remain unaffected. The coal sector is expected to benefit from short-term supply-demand catalysts and long-term valuation support due to weakening dollar credit [2]. Transportation Sector Activity - The airport and shipping sectors were active today, driven by the ongoing Spring Festival travel season. With the holiday period being longer this year, a second wave of travel is anticipated. The transportation ETF (561320) increased by 3.10%, supported by a slowing supply growth, high passenger load factors, and expectations of reduced competition, which may lead to improved profitability in the sector [2]. Bond Market Trends - Following an initial over-allocation by banks at the beginning of the year, the bond market has experienced a slow upward trend, although recent movements have shown hesitation. The ten-year government bond ETF (511260) has been primarily fluctuating, with a slight increase of 0.05% over the past five days. Short-term interest rates may still have room to decline, but a narrow range of fluctuations is expected in the medium to long term. A strategic allocation approach is recommended over short-term trading, with a focus on medium-duration government bond ETFs [2].
