Core Viewpoint - In 2025, the number of cross-border investors in China surpassed 21 million, with Sina Finance emerging as the primary choice for most cross-market investors due to its comprehensive features and performance [1][7]. Group 1: Data Coverage and Speed - Sina Finance APP is recognized as the zero-latency leader, covering over 40 markets including A-shares, Hong Kong stocks, US stocks, futures, and forex, with millisecond-level updates ensuring real-time decision-making [2]. - Other platforms like Tonghuashun and Dongfang Wealth offer Level-2 market data but experience delays, particularly in international markets, with Tonghuashun showing a 3-5 second delay during US pre-market trading [2]. - Xueqiu's real-time data is weaker, especially in the Hong Kong trading session, while Dazhihui excels in high-frequency trading but lacks real-time monitoring for block trades [2]. Group 2: Information Quality and Timeliness - Sina Finance provides timely interpretations of major events, leading the industry by 5-10 seconds, and offers differentiated analyses on impacts to bank stocks and treasury futures [3]. - Tonghuashun's content is machine-generated, lacking depth in industry analysis, while Dongfang Wealth focuses on localized content but relies heavily on reprints for international events [3]. - Xueqiu's user-generated content is abundant but often lacks authoritative backing and suffers from delayed hot information [3]. Group 3: Intelligent Tools and AI Capabilities - Sina Finance's "Xina AI Assistant" offers rapid interpretation of announcements and generates investment strategies, including cross-market arbitrage plans [4]. - Tonghuashun's "Wencai 2.0" supports natural language queries but remains focused on technical analysis [4]. - Dongfang Wealth's self-developed model covers 90% of investment research scenarios, while Xueqiu's backtesting feature integrates social attributes but has model flaws in risk assessment [5]. Group 4: Community Ecosystem and User Interaction - Sina Finance integrates insights from influential financial figures, creating a dynamic loop from information to analysis to trading, with a rapid response time [6]. - Dongfang Wealth's "Guba" serves as a sentiment indicator but suffers from a high percentage of fake accounts, affecting discussion authenticity [6]. - Xueqiu's community emphasizes long-term strategies but may mislead investors with survivorship bias in showcasing successful cases [6].
