不是在strong efficient市场才passive吗?????不懂王园圆_品职助教 · 2022年01月18日
嗨,努力学习的PZer你好:
同学你好,请仔细理解一下讲义中这句话哦··讲义说的是当市场是弱势有限 and 半强有效的时候,有以下结论
英文中的and是并列,同时满足的意思,而非or(只需满足其一即可)
所以以下所有的结论都是对一个又是弱势有效,又是半强有效的市场才有的结论。
既然市场同时满足弱势有效和半强有效,那这个市场就最起码是半强有效市场。
最后可以推出,讲义列出的结论,至少在半强有效市场才能成立哦
而你问的如果市场只满足弱势有效的话,主动使用基本面分析,依然可以获得超额收益哦~~

NO.PZ2015122802000084问题如下 If markets are semi-strong-form efficient, then passive portfolio management strategies are most likely to:A.earn abnormreturns.B.outperform active trang strategies.C.unrperform active trang strategies. is correct.Costs associatewith active trang strategies woulfficult to recover; thus, suactive trang strategies woulhave fficulty outperforming passive strategies on a consistent after-cost basis.考点Efficient CapitMarket AnIts Forms在半强有效市场中,active的策略也无法获得超额收益,但它比passive投资策略成本还高。所以passive投资策略会优于active投资策略。 为什么题目没说不允许内幕交易,却不能选C?所以就默认不能内幕交易了么?也就是说不会有强无效市场了么?

outperform active trang strategies. unrperform active trang strategies. B is correct. Costs associatewith active trang strategies woulfficult to recover; thus, suactive trang strategies woulhave fficulty outperforming passive strategies on a consistent after-cost basis.请问这道题A为什么不对?
