Measuring individual investors' speculative demand for stocks using the Google search volume index (hereafter “SVI”) on penny stocks, we examine how it relates to the return dynamics of U.S. stock indices. Speculative demand leads to a short-term return reversal. A simple trading strategy...

In the literature on sustainable investing, most studies assume normal market conditions. However, research is limited regarding the specific role of sustainable investing during stressed market conditions. In this paper, we contribute to the literature by investigating the role of ESG investing...

This study investigates the financial effects of additions to and deletions from two of the most well-known social stock indices: the Calvert social index and the MSCI KLD 400 index. By examining not only short-term abnormal returns but also trading activity, earnings per share and long-term...

Adding or deleting a security to or from an index can influence the share price considerably. A possible explanation that has been brought forward in the literature is the liquidity hypothesis according to which an increase in liquidity after an addition is responsible for the observed rise in...

This study evaluates whether exchange traded funds (ETFs) threaten fnancial market stability by testing two hypotheses relating the growing importance of ETFs to increased market volatility and rising equity valuations. We estimate quantile cointegration models using Standard & Poor's 500 Index...

In this paper we design a simple trading strategy to exploit the hypothesized distinct informational content of the arithmetic and geometric mean. The rejection of cointegration between the two stock market indicators supports this conjecture. The profits generated by this cheaply replicable...
