如题，在2021 MOCK III AM CASE 2 题目中，问到returns-based 分析的优缺点，这个内容在老师的讲义中并没有提及（貌似老师只说了优点）。而该题目答案所描述的内容有点接近trading这么课程中说描述的return-based的优缺点，不知道考试中能否跨科目去回答？
请问，如果在equity的相关case中再次出现两种方法的优缺点对比，我该如何写？这两种方法有什么明显优缺点？
附答案解析：
Drawbacks or limitations associated with the use of a returns-based style analysis relative to a holdings-based analysis include (either would be acceptable):
• Returns-based analyses are generally less accurate than holdings-based analyses because they do not utilize actual portfolio holdings.
• Most returns-based models impose unnecessary constraints that make it difficult to detect more aggressive positions such as deep value or micro-cap.
