在国际证券市场上,有种周末现象(weekend effect)。不过其实并不是单指周五有特殊的市场效应,而是泛指一周当中有些交易日涨跌概率高于其他交易日的现象。为了便于大家理解,我就秃笔一挥,姑且译作周日历效应。研究者发现这种现象存在于不同国家和不同类型的市场。在大部分西方国家,比如美国、英国、加拿大,股市涨幅在星期一平均起来比较弱,而星期五则比较强,看起来很奇怪,但对短线交易者非常有用。
In the international securities market, there is a weekend effect (weekend effect). However, in fact, it is not a single means that there is a special market effect on Friday, but refers to the phenomenon that the probability of change in some trading days during the week is higher than that of other trading days. In order to facilitate everyone to understand, I bald pen wave, tentatively translated into the weekly calendar effect. The researchers found that this phenomenon exists in different countries and different types of markets. In most western countries, such as the United States, Britain and Canada, stock market gains averaged weaker on Monday and Friday was stronger, which looked weird but very useful for short-term traders.
