1. Active, Passive or Enhanced? Sandip A. Bhagat, CFA Managing Director, Citigroup Asset Management President, Travelers Investment Management Company Presented at University of Connecticut Storrs, Connecticut February 20, 2004

2. Discussion Points • Evolution of Indexing • Role of Active Management • Structured Management or Enhanced Indexing as an Alternative • Implementation Choices in Asset Allocation

3. Growth of Indexing • $1.3 trillion in institutional indexed assets • Vanguard S&P 500 index fund has grown 8 fold in the last 5 years $ trillion $ billion

4. Factors Contributing toPopularity of Indexing • Shortfall of Active Management • Imbalance between size of information advantage and size of active bets • Academic Arguments of Market Efficiency • Self-Fulfilling Prophecy

5.

6. Potential Risks of Indexingto the S&P 500 • Reversal of Size and Style Effects • Lower Financial Asset Returns Shift Focus to Active Management • Reversal of Self-Fulfilling Prophecy

7. Role of Active Management • Good active managers deliver consistent value-added relative to a benchmark. • Good active managers will never fall out of favor or go out of style. • Active management should be used in inefficient asset classes.

8. Evaluating Active Management • Information ratios provide the litmus test of active management. • IR =  = = Active = Portfolio - Benchmark • A high information ratio differentiates skill from luck in active management. > + 0.5 Good < - 0.5 Bad   Active Return Active Risk 

9. Evaluating Active Management t-statistic = IR = , Standard Error of IR = 1/ IR > 0.5 implies a top quartile manager Estimate Standard Error T

10. > 1.6 T > 10 years 1 / T Evaluating Active Management t - statistic of 1.6 implies a 90% confidence level 0.5 If it can take more than 10 years to confidently identify a skilled active manager, how long would it take to identify a lucky or incompetent one?

11. Skill and Luck More Luck Insufferable Blessed Less Skill More Skill Doomed Forlorn Less Luck

12. Structured Management or Enhanced IndexingAs An Alternative • Disciplined investment style • Provides reliable asset class exposure • Adds value in a risk-controlled process • Combines desired attributes of reliability (purely passive) and value-added (purely active) into one style • Enhances asset allocation decision through risk control and value-added

13. Evolution of Asset Management Styles Expected Return Payoffs Relative to Benchmark Share of Enhanced vs. All Indexing 4 to 8% 30% 1 to 3% -0.1 to -0.3% < 5% -1 to -3% -4 to -8% • Asset Class Less More Reliable • Exposure Reliable Reliable • Value Added Less More Reliable, • Reliable Reliable but zero

14. Expectations From Enhanced Indexing Enhanced indexing represents a middle ground relative to passive and active management in terms of active risk, active returns and advisory fees. Large Mid Small Active Risk, bps 100-200 200-300 300-400 Active Return, bps 50-100 150-180 150-300 Advisory Fees, bps 10-25 25-50 50-70

16. Enhanced Indexing Approaches Portable Alpha Strategies (Tracking Error 1 to 3%): LIBOR Plus + Futures S&P 500 = S&P 500 Plus Market Neutral + Futures S&P 500 = S&P 500 Plus Long-short Convertible + Futures S&P 500 = S&P 500 Plus Arbitrage Mid Cap Alpha - Futures Mid cap+ Futures S&P 500 = S&P 500 Plus (Any Inefficient Asset Class) Derivatives arbitrage (eg. stock-index futures, rolling cheap calendar spreads) is now efficiently priced

19. Passive vs. Active:Role of Market Efficiency • Active management can be futile in efficiently priced markets (by definition). • Markets are generally efficient in the longer term but may provide short-term opportunities to exploit mispricing. • Emphasize active management in inefficient asset classes.

20. Market Efficiency and Implementation Choice Market Recommended Mix Asset Class Efficiency Passive Enhanced Active (%) (%) (%) Large U. S. Stocks High 40 30 30 Small U. S.

21. Summary • Various forms of indexing are likely to dominate in efficient asset classes. • Enhanced indexing • combines reliability and value-added to enhance asset allocation decisions and • may represent a cheaper outperformance call option • Active management can add significant value in inefficient asset classes by exploiting superior information. • Good active management, if you can find it, will always be in demand!
