  1. Access to Equity Markets, Corporate Investments and Stock Returns: International Evidence By Sheridan Titman: UT-Austin K.C. John Wei: HKUST Feixue Xie: UT-El Paso 2010 NTU Conference, Taipei December 10, 2010

  2. Introduction • Capital investment or asset growth anomaly • More investment ->lower subsequent stock returns • Cannot be explained by CAPM or Fama-French factor models • Baker, Stein, and Wurgler (2003), • Titman, Wei, and Xie (2004), • Anderson and Garcia-Feijoo (2006), • Fama and French (2008), • Cooper, Gulen, and Schill (2008), • Polk and Sapienza (2009), etc. • Exception: Japan (Titman, Wei, and Xie (2009))

  3. Behavioral Explanations: Overinvestment • Titman, Wei, and Xie (2004): Agency-based explanation • Management empire building tendency (expropriation, compensation, ego) • Jensen’s (1986) agency cost of free cash flow: Too much free cash flow  too much CAPX  overinvest • Market mis-reaction to overinvestment: initially underreacts, subsequently corrects its reaction to negative information on overinvestment, resulting in lower stock returns

  4. Behavioral Explanations Overconfidence explanation Heaton (2002): managers overestimate return on investment -> overinvestment Implication: cultures that promote overconfidence are likely to exhibit a stronger asset growth effect Corporate governance Good corporate governance may mitigate overinvestment Implications: factors that affect corporate overinvestment should also influence the asset growth effect If firms find it somewhat easier to overinvest in countries with easier access to equity markets, there may be a stronger asset growth effect in countries with better developed capital markets 9/5/2014 4

  5. Behavioral Explanations • Equity mispricing-based explanation (The catering theory of investment or the market timing theory) • Stein (1996) and Baker, Stein, and Wurgler (2003) • Firms overvalued or undervalued from time to time and firms tend to invest more when overvalued and less when undervalued. Empirical support: Polk and Sapienza (2009) • mispricing proxy: discretionary accruals (DAC) • negatively associated with future stock returns. • higher DAC firms  invest more

  6. Rational explanations • The q-theory explanation • Cochrane (1991, 1996), Li, Livdan, Zhang (2009), Liu, Whited, and Zhang (2009), and others • Rrequired rate of returns are time-varying and firms investment more when their required rates of return (expected returns) are lower (assuming that firms invest optimally): ROIC = CoC • The extended q-theory with investment frictions (Li and Zhang (2010)): the investment effect is stronger when frictions associated with increasing investment are stronger. • Implication: the asset growth effect is expected to be higher in countries with higher investment frictions

  7. Rational explanations • Option-theory explanation • Berk, Green, and Naik (1999): after growth options are exercised (increased investment), risk is reduced, -> expected returns are lower

  8. Main objectives Overinvestment can be caused by the agency cost of free cash flow, managerial overconfidence, or equity overvaluation Objectives: To examine the asset growth effect in an international setting To examine the extent to which the cross-country variation in the asset growth effect is generated by cross-country differences incountry characteristics such as the development of local equity markets, managerial overconfidence, and legal protection 9/5/2014 8

  9. Main Findings Using data from over 13,300 firms across 40 countries during 1981-2005, there exists the investment effect outside the United States With a few exceptions, most countries exhibit a negative relation between asset growth and subsequent stock returns As a whole, the asset growth effect is highly significant among developed countries, but is very weak and insignificant among developing countries The asset growth effect in developed markets is very persistent and lasts for at least five years after portfolio formation 9/5/2014 9

  10. Main Findings Among developed countries, the difference in the asset growth effect can be explained by the cross-country difference in the ease of access to equity markets or equity market development the asset growth effect is 0.58% per month (or about 7% per year) higher in countries in the top 30% than in the bottom 30% of all developed countries in the access-to-equity market index The asset growth effect is also stronger in countries with more overconfidence, and strong legal protection The inclusion of these country variables does not materially affect the significant influence of the access to equity markets on the asset growth effect 9/5/2014 10

  11. Data: Country-level variables The ease of access to external markets the index of access-to-equity market: Global Competitiveness Report from 1999 to 2006 surveyed by World Economic Forum the ratio of stock market capitalization to gross domestic product (GDP) scaled by the fraction of stock market held by outside investors Both are used by La Porta, Lopez-de-Silanes, and Shleifer (2006) Overconfidence The individualism index: from Hofstede (1980, 2001) Used by Chui, Titman, and Wei (2010) 9/5/2014 11

  12. Data: Country-level variables Corporate governance (Legal protection of investors) the anti-self-dealing index It is from Djankov, La Porta, Lopez-de-Silanes, and Shleifer (2008) Firm-level data: Financial and market data The US: CRSP and Compustat Other countries: Datastream 9/5/2014 12

  13. Measurement of firm-level variables Total asset growth rate (TAG) TAGit = (TAit – TAit-1)/TAit-1 Alternative measures Capx divided by net fixed assets and its variants Firm size (SZ) Book-to-market ratio (BM) Momentum (MOM) Equity issuance (Issue) 9/5/2014 13

  14. Preliminary Results: Country by country • Stocks are sorted into TAG quintiles for each country • Table 1: The country-by-country asset growth effects • Among developed countries, only 2 countries exhibit a reversed asset growth effect (Israel and New Zealand) and both are insignificant • 14 out of the 26 developed countries have a significant asset growth effect • The asset growth effect is very weak in developing countries • Only 3 out of the 14 developing countries have a significant asset growth effect • a considerable variation in the investment effect across countries • the developed countries as a whole show a strong and significant global investment effect, but not among developing countries

  17. Preliminary Results: Persistence Table 2: The persistence of the investment effect Raw returns There exists a persistent asset growth effect for all economies as a whole, but the persistence mainly comes from the developed economies. No asset growth effect in any of the 5 years after portfolio formation for the developing countries BM and SZ adjusted returns The same return patterns are observed but are weaker than those based on raw returns. 9/5/2014 17

  19. Preliminary Results: Regression analysis Table 3: Regression analysis from both regression models: total asset growth has a strong and negative effect on subsequent stock returns for all sample economies or the developed economies No asset growth effect for the developing economies Share issuance also has a negative effect on stock returns for the whole sample and developed countries. But the inclusion of share issuance does not damper the effect of asset growth on stock returns: the catering theory of investment cannot fully explain the asset growth effect Implications from Tables 1 and 3: The results appear to be consistent with the overinvestment explanation inconsistent with the prediction of the q-theory with investment frictions 9/5/2014 19

  21. Summary statistics and correlations Table 4: Summary statistics The developed countries have a higher average access-to-market index than the developing countries with a value of 5.76 vs 4.78 a higher average market cap to GDP ratio with a value of 0.59 vs 0.30. a higher average individualism index with a value of 60 vs 35. a higher average BM and SZ adjusted TAG-hedge returns with a value of 0.27% vs 0.08% per month. there are more significant correlations in the developed economies than in the developing economies. The correlations between the TAG-hedge returns and most other variables are significant in the developed economies, but not in the developing economies. 9/5/2014 21

  23. Explanations for cross-country differences in the asset growth effect: Regression analysis Table 5: Regression analysis (Access to equity markets) The asset growth effect is significantly stronger in countries with easy access to capital markets than in countries with limited access to capital markets as measured by the access to equity market index (Panel A) or the market ca to GDP ratio (Panel B) Implications: consistent with the overinvestment explanation and inconsistent with the prediction of the q-theory with investment frictions There is no significant difference in the asset growth effect between the high and low individualism countries (Panel C) but a significant difference between the strong and weak investor protection countries (Panel D) Implications: inconsistent with the corporate governance argument 9/5/2014 23

  26. Explanations for cross-country differences in the asset growth effect: Portfolio analysis Table 6: Portfolio analysis The asset growth effect is significantly stronger in countries with easy access to capital markets than in countries with limited access to capital markets as measured by the access to equity market index or the market cap to GDP ratio in developed countries The asset growth effect is significantly stronger in countries with higher individualism or in countries with stronger investor protection for developed countries. 9/5/2014 26

  27. Country institutions and the TAG effect 9/5/2014 27

  28. Explanations for cross-country differences in the asset growth effect: Regression analysis Table 7: Regression analysis (univariate regressions) Panels A & B: The asset growth effect is stronger in developed countries with easy access to capital markets as measured by the access to equity market index (Model 1) or the market cap to GDP ratio (Model 2), or high individualism (more overconfidence) (Model 3). The asset growth effect is stronger in developed countries with stronger investor protection only for the whole sample but not for the subsample starting from 1988. 9/5/2014 28

  29. Explanations for cross-country differences in the asset growth effect: Regression analysis Table 7: Regression analysis (multivariate regressions) The inclusion of individualism, and legal protection does not damper the influence of access to capital markets on the asset growth effect in developed markets In addition, individualism is also significant Implications from Tables 6 and 7: confirm the previous results. Consistent with the overinvestment explanation and inconsistent with the prediction of the q-theory with investment frictions 9/5/2014 29

  30. Explanations for cross-country differences in the asset growth effect: Regression analysis Panel A: The whole sample period Panel B: Subsample period starting 1988 9/5/2014 30

  31. Conclusion There is the asset growth effect outside the United States. We find a strong asset growth effect among developed economies but not among developing economies. Developed countries with easy access to equity markets and more overconfidence cultures show a stronger asset growth effect, possibly through a propensity-to-overinvest channel. But the inclusion of these country institutional variables does not damper the effect of the ease of access to equity markets. Our results appear to be generally consistent with an overinvestment explanation by Titman, Wei, and Xie (2004) and to be inconsistent with the prediction by the q-theory with investment frictions suggested by Li and Zhang (2010). 9/5/2014 31

  32. Conclusion In sum, we provide evidence that cross-country differences in access to equity markets and cultures can affect cross-country differences in the asset growth effect. Our results provide a challenge to market efficient hypothesis and behavioral as well as the traditional risk-based theories. Risk-based: Why asset growth portfolios are risky in developed countries but not in developing markets? Behavior based: why managers have a tendency to overinvest and at the same time investors tend to underreact to the negative information contained in overinvestment in developed markets, but it is in developing markets? 9/5/2014 32
