申报季度: 2026-03-31 · 持股只数: 88
Mainstream Capital Management LLC在最新一期 13F 报告中披露了 88 项持股，申报期为 2026-03-31，总持股市值约为 US$1.5亿，季度换手率为 15.3%。
Mainstream Capital Management LLC 目前披露的持仓，Herfindahl 集中度指数为 0.039——换算下来相当于约 26 个等权重仓位，明显低于其实际披露的 88 只持仓。这一差距显示该机构的策略偏向集中在少数高信心仓位，而非广泛分散。
整体仓位大小差异较大（变异系数为 1.57），除少数重仓仓位外，还有许多规模较小的持仓。
最新申报季度中，并未观察到明显偏向加仓既有大仓位或大举建立新仓位的倾向。
目前行业板块分类约覆盖此投资组合披露价值的 46%；其余部分（例如未匹配板块的标的、期权或其他证券类型）尚未纳入板块分类范围。
