Adam同学你好,
这三个只是基本假设：
1：Asset returns can be explained by systemic factors.资产收益由因素模型决定.
2：By using diversification, investors can eliminate specific risk from their portfolios.分散化可消除特定风险因子
3：There are no arbitrage opportunities among well-diversified portfolios. If any arbitrage opportunities were to exist, investors would exploit them away.无套利
