几个大家意想不到的投资策略，基金已经用上了

Group 1 - The article discusses unexpected investment strategies that have been adopted by some funds, particularly focusing on the performance of the Beijing Stock Exchange (BSE) and its impact on fund returns [4]. - Funds heavily invested in BSE stocks, such as Xinghua Jingcheng Mixed Fund, Tongtai Kaitai Mixed Fund, and Tongtai Yuanjian Mixed Fund, have shown significant short-term performance due to the BSE's recent outperformance compared to the Shanghai and Shenzhen markets [5][6]. - The BSE has a 30% limit on price fluctuations, which, combined with its lower liquidity compared to the main board, results in higher volatility for funds employing this strategy. This limits the scale of such funds, making it challenging for larger companies to participate [7]. Group 2 - The article introduces the concept of global rotation, where funds adjust their market allocations across different regions, such as A-shares, Hong Kong stocks, and U.S. stocks. An example is the Chuangjin Hexin Global Pharmaceutical and Biotechnology Fund, which has successfully adjusted its allocations this year, particularly reducing Hong Kong stocks and increasing U.S. stocks [8][9]. - Some sectors or themes may be more suitable for global rotation strategies, indicating potential for more products to explore this approach [9]. - The article also mentions ETF rotation strategies, particularly among funds of funds (FOFs) like Guotai Industry Rotation Stock Fund, which can engage in ETF rotation despite having limited positions [10][11]. - FOF products capable of ETF rotation tend to exhibit higher volatility compared to their peers, often ranking at both ends of the performance spectrum, which requires not only skill but also a strong mindset from investors [12].
