Henley Public Lecture: Dr Andreas Hoepner discusses the myth of outperforming “sin firms”

Professor of Finance at the ICMA Centre Dr Andreas Hoepner addressed an audience of Henley Business School students and external visitors at this year’s Henley Business School Public Lecture.

The lecture, titled “Investing in sin firms: is vice really nice?”, brought into question a paper published by Hong & Kacperczyk in 2009, which claimed that so called “sin firms” – business specialising in vice products like alcohol, tobacco and gambling – outperformed other firms, an idea that was relished by press at the time.

During the lecture, Hoepner addressed how the paper that he and co-author Hampus Adamsson produced “The Price of Sin Aversion” sought to first duplicate the research methods used by HK, and then amend and improve the methodology in order to try to assess if the results held water in a real world research setting.

“First we used the same method as Hong & Kacperczyk to test that we received the same results,” Andreas commented. “However, when using a financial data science approach rather than classic financial economics analysis, the moment we controlled in-sector size and value controls the outperformance of the sin stocks disappeared in almost every case.”

Hoepner finished off the lecture with an example of the practical uses of financial data science, using an example of the 2010 Germany-England world cup, demonstrating a graph that was able to use Twitter comments to plot supporters' “sentiment” towards each team during the match.

The lecture was held at Henley Business School’s ICMA Centre which specialises in undergraduate and postgraduate degrees in finance at University of Reading, and is home to an extensive trading simulation terminals supported by Bloomberg and Thomson Reuters.

A Free Lunch?

29 August 2018
Fidelity, the asset manager with $2.4 trillion assets under management, recently announced the launch of two index mutual funds with a 0% fee! This announcement is interesting for several reasons. First, the asset management industry has been involved in an intense price war and this new fee level of 0% represents a very tough benchmark for the competition to beat. Not surprisingly, the share price of rival asset managers fell by a few percentage points shortly after the announcement. Second, the new fee level is unusual as it indicates that, for the first time, investors could get exposure to both US and international equities without incurring any fee. This is a curious business decision. How will Fidelity manage to pay for all its expenses? Will this product be a loss-making venture? Is there more to it than meets the eyes?
