摘要
建设性地将投资组合前沿扩展到一个误差带上,称为"投资组合前沿带"。提出了次优理论范畴的投资组合模型集可以避免不必要的损失,投资组合模型集的提出将更"人性化"地供投资者选用,具有更好的应用价值。
The portfolio frontier was creatively expanded to a frontier belt called ＂portfolio frontier belt＂. The portfolio model gathering of the hypo - optimal theory was put forward to avoid the unnecessary loss. It offers more humane choices for investors and has better application values.
