Outline for an Academic Approach• Sustainable and Responsible Investment strategies• SRI value creation in financial markets• ESG metrics in research papers• Errors in investors’ expectations and learning
– The alpha puzzle and market efficiency
– Learning and Disappearing Association between Governance and Returns (Bebchuk et al., JFE 2013)
– Stakeholder Relations and Stock Returns: On Errors in Investors’ Expectations and Learning (Borgers et al., JEF 2013)
• Evidence from academic studies on portfolio analysis, event studies around earnings announcements, analysis of errors in analysts’ forecasts, and firm value studies
• Conclusions with implications
Sustainable and Responsible Investment Strategies
SRI in Europe - Eurosif
SRI – by Country
ESG Value Creation in Financial Markets
• How does market price ESG ? Extra-financial value
• The market overlooks the benefits of ESG?
• ESG at firm level associated with productivity, efficiency, and hence, cash flow
• When benefits to ESG materialize, SRI investor enjoys positive earnings “surprise”?
Alpha ESG drives future cash flows
Impact on company valuation
Errors in consensus

ESG and Stock Return – Alpha Puzzle
Institutions often justify their responsible practices using the argument that ESG factors generate positive investment returns (alpha).
Investors (and companies) that exploit this market inefficiency will benefit from an early mover advantage that can last decades before risk-return equilibrium is established (2012)
ESG and Stock Return – Alpha Puzzle
Abnormal return!Derwall et al (FAJ, 2005): The high-ranked portfolio based on Innovest eco-efficiency ratings provided substantially higher average returns than its low-ranked counterpart over the 1995-2003 period.
ESG and Stock Return – Positive Alpha
Abnormal Return - Mispricing? Factors: market, small-large, value-growth, momentum
Stock market anomalies
• Classical EMT suggests that trading strategy based on public information cannot produce abnormal returns (Fama, 1970).
• Adaptive EMT suggests that the ability of trading strategy to generate abnormal returns will disappear over time (Daniel and Titman, 1999).
• Errors in expectations and Learning – evidence from SRI studies (Bebchuck and Borgers studies, 2013)
Errors in Investors’ Expectations and Learning
Intangible nature of ESG Mispriced information eventually disappears when
investors learn about the anomaly Increased integration of ESG factors Media and research attention More shareholder proposals on ESG issues
Positive risk-adjusted returns on portfolios of high-ranked ESG stocks will disappear
ESG earnings surprises will disappear Positive association with firm value (Tobin’s Q) will
persist
Governance and stock returns
• Learning and disappearing association between governance and returns by Bebchuk, Cohen, Wang (JFE, 2013)
• Investor Responsibility Research Center (IRRC) Corporate Governance data on S&P 500– Democracy firms (Good G) and Dictatorship forms (Bad G) based on
• G-Index (24 IRRC provisions; such as voting rights, CEO protection, tactics for delaying hostile bidders, other takeover defences)
• E-Index (limited to 6 IRRC provisions)
– High G-Index and E-Index (protection) = poor Governance
– Periods: 1990-2008; 1990-1999 and 2000-2008
Good Governance Effect• The disappearance of the governance-return correlation was associated
with an increase in the attention to governance by a wide range of market participants;
• Until the beginning of the 2000s, stock market reactions to earning announcements reflected the market’s being more positively surprised by the earning announcements of good-governance firms than by those of poor-governance firms;
• Stock analysts were also more positively surprised by the earning announcements of good-governance firms than by those of poor-governance firms until the beginning of the 2000s but not afterwards;
• While the G-Index and E-Index could no longer generate abnormal returns in the 2000s, their negative association with Tobin’s Q and operating performance persisted (good-governance firms higher market value).
Attention paid to G by media and institutional investors increased from 2000
Structural break in abnormal G returns occurred in November 2000Critical learning point occurred in October 2001
Governance indices and abnormal stock returns
Abnormal returns fade out over time
Governance indices and operating performance and Tobin’s Q
Association between governance indices and operating performance and Q persist during both 1990-2001 and 2002-2008
Environmental and Social information and stock returns
• Stakeholder relations and stock returns: On errors in investors’ expectations and learning (Borgers et al, JEF 2013)
• Stakeholder-relations index, SI– (KLD ES ratings: emissions and pollution prevention,
environmental management systems, community involvement, diversity, employee relations, product quality, human rights)
• High SI = high ES ratings• U.S large cap 1000-3000 firms (1992-2009; 1992-2004
and 2004-2009)
ES mispricing is eliminated
• Provide evidence that the Stakeholder-relations Index (SI) explained errors in investors' expectations about firms' future earnings 1992–2004. – SI was positively associated with long-term risk-adjusted
returns, – Earnings announcement returns, and – Errors in analysts' earnings forecasts over the period
• When attention for stakeholder issues became more widespread, these relationships diminished considerably.
• The results are consistent with the idea that increased investor attention for stakeholder issues eliminates mispricing.

Conclusions and Implications• Mispriced ESG information has generated in the past superior
risk-adjusted returns in the short run• Increased attention for ESG issues has eliminated errors in
investors expectations in the long run (learning effect) – Correlation between G and abnormal returns disappears from 2000– Correlation between ES and abnormal returns disappears from
2004• Public ESG information used by researchers is not able to
provide a basis for profitable trading strategy.• Positive association with operating performance and market
value persists in the long run • ESG becomes more significant in the market and to be taken
into account by investors
