This paper investigates abnormal standardized returns (ASRs) after major corporate events. Dutta, Knif, Kolari, and Pynnonen (2018) have shown that the ASR t-test has superior size and power compared to traditional test statistics. Based on this new test statistic compared to traditional test...

This paper examines how the size of the rolling window, and the frequency used in moving average (MA) trading strategies, affects financial performance when risk is measured. We use the MA rule for market timing, that is, for when to buy stocks and when to shift to the risk-free rate. The...

Stocks with increases in idiosyncratic risk tend to earn low subsequent returns for a few months. However, high idiosyncratic risk stocks eventually earn persistently high returns. These results are consistent with positively priced idiosyncratic risk and temporary underreaction to idiosyncratic...

In this paper we investigate sources and characteristics of value, size and momentum profits on the Polish stock market. The research aims to broaden the academic knowledge in a few ways. First, we deliver fresh out-of-sample evidence on value, momentum, and size premiums. Second, we analyzemthe...

This study aims to explore the performance persistence of frontier market equity anomalies. To this end, I replicate 140 anomalies in the cross-section of returns in a sample of 23 frontier markets. I demonstrate a robust and strong performance persistence in the anomaly returns. The return...

We analyze short-term reversal and medium-term momentum patterns in weekly stock returns in Europe. Focusing on raw and on stock-specific returns, our empirical results show for both return specifications i) a negative relation between weekly past returns and future returns in the short run and...

Our paper investigates extended abnormal returns for S&P 500 index changes in a comprehensive 1979-2015 sample. The literature's depiction of longer window returns lacked both appropriate nuance and cross-sectional analysis. Solid evidence for reversion appears in the 2000s. It suggests that...

Using a novel collection of market characteristics from 40 countries, this paper test competing explanations behind five major anomalies classified in Hou, Xue, and Zhang (2015): momentum, value-growth, investment, profitability, and trading frictions. Results show that anomaly returns highly...

This paper finds evidence that stock returns vary with the physical climate change exposure of firms in a predictable manner. We construct measures of exposures to physical climate changes at the firm level, and find that firms with high climate change exposures experience lower future...
