题目信息:
“A financial analyst is examining whether a country’s financial market is well functioning. She finds that the transaction costs in this market are low and trading volumes are high. She concludes that the market is quite liquid. In such a market:
A. traders will find it hard to make use of their information.
B. traders will find it easy to trade and their trading will make the market less informationally efficient.
C. traders will find it easy to trade and their trading will make the market more informationally efficient.”
问题回复:
市场越有效,意味着信息传递和价格调整越迅速,市场参与者对信息的反应越敏锐。在这样的市场中,由于信息差异导致的交易机会减少,因此交易者使用他们的信息来获得超额收益的难度增加。
即使在强式有效市场中,也存在利用信息差异进行交易的可能性,但这样的机会通常需要更专业的知识和技能,以及对市场动态的深刻理解。交易者可能需要更快地获取和处理信息,采用更复杂的交易策略,以及承担更高的风险,才能在市场中取得成功。
又或者,在市场有效中,价格已经反应了信息,如果投资者获得了该信息,他不使用该信息进行分析的话,他怎么知道价格已经反应了该信息。
