Article history: Received 9 March 2007 Accepted 9 July 2008 Available online 12 October 2008 We examine four European stock indices and the prices of eight major German stocks for indications of psychological barriers. The frequency, (expected) returns, intraday volatility and trading volume of these assets are studied contingent on whether the prices lie within a certain range around round num...

This paper provides new empirical evidence that price-based technical indicator variables can enhance the ability of accounting variables in explaining cross-sectional stock returns. We apply both OLS and state-space modelling to a sample of firms included in the Russell 3000 index over the period from 1999-2012 to compare the roles of the two main types of information typically used by stock i...

Article history: Received 22 September 2011 Received in revised form 28 January 2013 Accepted 2 February 2013 Available online 9 February 2013 This paper analyzes the investor sentiment effect in four key European stock markets: France, Germany, Spain and the UK. The findings show that sentiment has a significant influence on returns, varying in intensity across markets. The variation appears t...

Recent empirical research in finance has uncovered two families of pervasive regularities: underreaction of stock prices to news such as earnings announcements, and overreaction of stock prices to a series of good or bad news. In this paper, we present a parsimonious model of investor sentiment, or of how investors form beliefs, which is consistent with the empirical findings. The model is base...

In this paper we provide empirical findings on the significance of positive feedback trading for the return behavior in the German stock market. Relying on the ShillerSentana-Wadhwani model, we use the link between index return auto-correlation and volatility to obtain a better understanding into the return characteristics generated by traders adhering to positive feedback trading strategies. O...

Donald Trump’s election was a significant surprise. The reaction of company stock prices to the election reflects shifts in investor expectations about economic growth, taxes, and trade policy. High-beta stocks outperformed, presumably due to strengthened growth expectations. Expectations of significant corporate tax cuts boosted high-tax firms, but hurt firms with significant net operating los...

Article history: Received 7 November 2013 Accepted 30 March 2014 Available online 26 April 2014 The decentralized OTC market is extremely illiquid and opaque in comparison with the exchange-listed stock market. Although liquidity risk has been well documented in the finance literature, little is known about how liquidity risk affects the stocks traded in the decentralized OTC market. In this st...

I present evidence of inefficient information processing in equity markets by documenting that negative information withheld by securities analysts is incorporated in stock prices with a significant delay. I estimate the extent of the withheld negative information based on the proportion of analysts who stop revising their annual earnings forecasts. This measure predicts negative earnings surpr...

This paper provides evidence that a firm’s stock price movements affect its customer demand. I develop a model in which customers learn about a firm’s product quality partially from its stock price. This learning induces feedback from the price to customer demand. Furthermore, the firm manager adjusts product launch decisions in anticipation of these demand shifts. Consistent with the model’s i...

Researchers have reported mispricing in index options markets. This study further examines the efficiency of the S&P 500 index options market by testing theoretical pricing relationships implied by no-arbitrage conditions. The effect of a traded stock basket, Standard and Poor’s Depository Receipts (SPDRs), on the link between index and options markets is also examined. Pricing efficiency withi...
