Abstract We zero in on the expected returns of long-short portfolios based 204 stock market anomalies by accounting for i) effective bid–ask spreads, ii) post-publication effects, and iii) modern era trading technology that began early 2000s. Net these average anomaly’s return is a measly 4 bps per month. The strongest net, at best, 10 after controlling data mining. Several methods combining ne...

The electricity market has evolved from a regulated monopoly to a more liberalized competitive market, which allows a generating company (GENCO) to bid to provide energy. The two-period structure of the electricity market (day-ahead and real-time market) introduces a mechanism for determining the GENCO’s optimal bidding strategy. The difference between clearing prices for each period adds uncer...

We study the problem of a market-maker acting as a liquidity provider by continuously setting bid and ask prices for an illiquid asset. We assume that the market maker has a contractual obligation to permanently quote bid and ask prices for the security and therefore to satisfy any sell or buy order from the asset’s investors. On the opposite side of the trades, there are investors who act as l...

This paper develops a model of a learning market-maker by extending the GlostenMilgrom model of dealer markets. The market-maker tracks the changing true value of a stock in settings with informed traders (with noisy signals) and liquidity traders, and sets bid and ask prices based on its estimate of the true value. We empirically evaluate the performance of the market-maker in markets with dif...

This study tests the hypothesis that market value added (MVA) is more highly associated with stock return (SR) than traditional performance measures. The purpose of this study is to provide empirical evidence on the relative and incremental information content of MVA and traditional performance measures, namely, net income (NI), net operational profit after tax (NOPAT), and earning per shares (...
