Seminar - Do Exchange Traded Funds (ETFs) Increase Volatility?

10:30 - 12:00 | Room W2.01 (Cambridge Judge Business School)

Professor Francesco Franzoni, University of Lugano and the Swiss Finance Institute

We study whether exchange traded funds (ETFs) impact the volatility of their underlying stocks. Using mechanical variation in ETF ownership, we present evidence that stocks owned by ETFs exhibit significantly higher intraday and daily volatility. A one standard deviation higher ETF ownership is associated with daily stock volatility higher by 16 per cent. The driving channel appears to be arbitrage activity between ETFs and the underlying stocks. The effects are stronger for stocks with high limits to arbitrage. Finally, the evidence that ETF ownership increases stock turnover suggests that ETF arbitrage adds a new layer of trading to the underlying securities.

Seminar - Scenario-Free Stochastic Programming: Methodology and Applications

14:00 - 15:00 | Room W2.02 (Cambridge Judge Business School)

Dr Wolfram Wiesemann, Imperial College Business School

Traditional optimisation models only involve deterministic parameters whose values are assumed to be known precisely. However, many practical decision problems involve uncertain parameters such as future prices and resource availabilities. It has been shown that treating these parameters as deterministic quantities can lead to severely suboptimal or even infeasible decisions. Stochastic programming overcomes this deficiency by faithfully treating the uncertain parameters as random variables.

Seminar - Who Are You Promoting? Positive Voluntary Public Disclosure & Executive Turnover

11:00 - 12:00 | Room W2.01 (Cambridge Judge Business School)

Dr Ithai Stern, Kellogg School of Management

This paper brings together two complementary research streams that have largely ignored each other: strategic human resource management and media relations management. We argue that when publicly traded firms voluntarily and publicly disclose positive information about their value creation and appropriation activities, they also send positive signals to managerial labour markets regarding executives' opportunity recognition and exploitation capabilities. Accordingly, we hypothesise a positive association between public disclosures and voluntary executive turnover. An analysis of a sample of pharmaceutical and communications equipment firms from 1990 to 2004 strongly supports this prediction, underscoring the need to better understand the effects of voluntary public disclosures on a firm's ability to isolate its human capital and protect it from expropriation by rivals. More generally, our results show how a firm's efforts to create value may ironically diminish its ability to realise that value later on.

This seminar is organised in association with the Cambridge Corporate Governance Network.

Cambridge EdTech Startup Weekend

08:00 - 18:00 | Cambridge Judge Business School

Ever wondered what it takes to be an entrepreneur? The professional and personal challenges, the high and lows, the failures and the success? At this Startup Weekend, taking place 23-25 May, anyone is welcome to pitch their start-up idea and receive feedback from their peers. Teams organically form around the top ideas (as determined by popular vote) and then it's a 54-hour frenzy of business model creation, coding, designing, and market validation. The weekends culminate with presentations in front of local entrepreneurial leaders with another opportunity for critical feedback.
