Optimal investment of firms implies that expected stock returns are tied with the expected marginal benefit of investment divided by the marginal cost of investment. Winners have higher expected growth and expected marginal productivity (two major components of the marginal benefit of...

We offer an investment-based interpretation of price and earnings momentum. The neoclassical theory of investment implies that expected stock returns are tied with the expected marginal benefit of investment divided by the marginal cost of investment. Winners have higher expected growth and...

We create a firm-level ChatGPT investment score, based on conference calls, that measures managers' anticipated changes in capital expenditures. We validate the score with interpretable textual content and its strong correlation with CFO survey responses. The investment score predicts future...

Using theories from the behavioral finance literature to predict that investors are attracted to industries with more salient outcomes and that therefore firms in such industries have higher valuations, we find that firms in industries that have high industry-level dispersion of profitability...

We examine the performance of the buy-write option strategy (BWS) on the Australian Stock Exchange and analyse whether such an investment opportunity violates the efficient market hypothesis on the basis of its risk and returns. This study investigates the relationship between buy-write...

Equity research analysts tend to cover firms about which they have favorable views. We exploit this tendency to infer analysts' preferences for corporate policies from their coverage decisions. We then use exogenous analyst disappearances to examine the effect of these preferences on corporate...

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...

While the unfolding financial turmoil has involved new elements, more fundamental elements have remained the same. New elements include structured credit, the originate-to-distribute business model and the tri-party repurchase agreement. The recurrence of crises reflects a basic procyclicality...

We propose a novel measure of risk perceptions: the price of volatile stocks (PVSt), defined as the book-to-market ratio of low-volatility stocks minus the book-to-market ratio of high-volatility stocks. PVSt is high when perceived risk directly measured from surveys and option prices is low....

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...
