We consider the finite-time optimal portfolio liquidation problem for a von Neumann-Morgenstern investor with constant absolute risk aversion (CARA). As underlying market impact model, we use the continuous-time liquidity model of Almgren and Chriss (2000). We show that the expected utility of...

We consider the problem faced by an investor who must liquidate a given basket of assets over a finite time horizon. The investor's goal is to maximize the expected utility of the sales revenues over a class of adaptive strategies. We assume that the investor's utility has constant absolute risk...

This study analyzed activism that leads to a merger or acquisition (M&A) of a firm to see its benefits for the shareholders at the target firm as well as its acquirer. It used over thirty years of data to understand the impact of the activists’ demands of strategic significance for the firms....

This paper examines local bias in the context of venture capital (VC) investments. Based on a sample of US VC investments between 1980 and June 2009, we find more reputable VCs (older, larger, more experienced, and with stronger IPO track record) and VCs with broader networks exhibit less local...

Using a comprehensive dataset of hedge fund 13F filings, we analyze hedge fund trading from 1998-2010 to determine if investor redemptions cause fire sales and stock market disruptions. We find evidence of hedge fund fire sales in the two quarters with the worst stock market performance. During...

In this paper we use the tools and frameworks from Oxford University’s postgraduate diploma in financial strategy to study the performance and benefits of algorithmic trading strategies (algos), and specifically those that use artificial intelligence (AI) and machine learning (ML).We discover...

We study the sources of cross-sectional variation in the performance of first-time venture capital (VC) fund partners (GPs). We find that, relative to GPs with startup experience (creators), GPs with VC experience (managers) are at least 20 percent more likely to invest in successful deals or...

Using close to 800,000 transactions by 66,000 households in the United States and close to 2,000,000 transactions by 303,000 households in Finland, this paper shows that individual investors with longer holding periods choose to hold less liquid stocks in their portfolios, consistent with Amihud...

We provide detailed descriptions, including over 550 mathematical formulas, for over 150 trading strategies across a host of asset classes (and trading styles). This includes stocks, options, fixed income, futures, ETFs, indexes, commodities, foreign exchange, convertibles, structured assets,...

We test and confirm the hypothesis that individual investors are net buyers of attention-grabbing stocks, e.g., stocks in the news, stocks experiencing high abnormal trading volume, and stocks with extreme one day returns. Attention-driven buying results from the difficulty that investors have...
