Weak-Form Efficiency Vs Semi-Strong Form Efficiency in Price Discovery: an Application to International Black Tea Markets

Weak-Form Efficiency In The German Stock Market

Testing Semi-strong Form Efficiency of Stock Market

The efficient market hypothesis suggests that stock markets are “informationally efficient”. That is, any new information relevant to the market is spontaneously reflected in the stock prices. A consequence of this hypothesis is that past prices cannot have any predictive power for future prices once the current prices have been used as an explanatory variable. In other words the change in futu...

Weak-Form and Semi-Strong-Form Stock Return Predictability Revisited

T paper makes indirect inference about the time variation in expected stock returns by comparing unconditional sample variances to estimates of expected conditional variances. The evidence reveals more predictability as more information is used, and there is no evidence that predictability has diminished in recent years. Semi-strong-form evidence suggests that time variation in expected returns...
