Asset Allocation Based On Beta and Alpha Drivers
Asset allocation is one of portfolio managements dominant concerns. Asset allocation answers several questions. What risk-return trade-off are we comfortable with? In other words what amount of risk are we prepared to take to make a certain level of active return? At every level of active return there is an equivalent amount of risk. Many portfolio managers are judged merely on the return they have achieved without later examination of the risk they took to produce that return. This is the reason why we have seen the arrival of new rogue traders like Kweku Odoboli. These traders want to make locaiongs that give a certain amount of return so as to meet their stringent benchmarks.
Asset allocation can be done using either alpha or beta drivers. The alpha drivers measure the managers skill to generate the so-called active return. Active return is the difference between the benchmark and the actual return. Alpha is more aggressive and aims to unprotected to returns in excess of the stated benchmarks. Alpha drivers are typically classified as Tactical Asset Allocation (TAA). TAA facilitates an investors long-term funding goals by seeking additional return. It focuses of arbitrage in the sense that it takes advantage of unbalanced market fundamentals. TAA requires more frequent trading than does Strategic Asset Allocation (SAA) to produce the additional returns.
Beta drivers are the more traditional investment techniques that aim to meet the benchmarks. It involves the methodic capture of existing risk premiums. Beta drivers are used in constructing SAA. This kind of allocation crystallizes an institutional investors investment policy. This course of action singles out strategic benchmarks tied to general asset classes that establish the policy/ beta/ market risk. This kind of allocation is not designed to beat the market and must meet the long-term funding goals of the organizations like defined assistance pension schemes.
general Classes of Alpha Drivers
1. Long or short investing
2. Absolute return strategies (hedge funds)
3. Market segmentation
4. Concentrated portfolios
5. Non-linear return processes (option-like payoff)
6. different cheap beta (anything outside the normal stock/bond portfolio)
Typical Asset Allocation for an Institutional Portfolio
Fixed Income 30%
Real Estate 15%
Inflation Protection 15%
Breaking down the equity portion
Strategic allocation to equity could be broken down into the following sub-classes:
Beta drivers – 60%
• Passive equity
• Enhanced index equity
Alpha drivers – 40%
• Private equity
• Distressed debt
Convertible bonds have a hybrid structure which is a combination of equity and fixed income securities consequently may be included in either the equity or fixed income bucket.
Fixed income portfolio
This section of the portfolio may also be broken down into alpha and beta drivers. The fixed income portfolio may be allocated in the following way:
Beta drivers – 60%
• US treasury bonds
• Investment grade corporate bonds
• Agency mortgage-backed securities
Alpha drivers – 40%
• Convertible bonds, high provide bonds and mezzanine debt
• Collaterised debt obligation (CDO) and collaterised loan obligation (CLO)
• Fixed income-based hedge fund strategies, fixed income arbitrage relative value, distressed debt
15% Inflation hedging
This is an investment strategy that aims to provide a cushion against the risk of a money decreasing in value. Other investment may produce returns in excess of inflation but inflation hedging is specifically tailored to preserve value of a money. The following is how you can divided the inflation hedging portion of your portfolio:
TIPS (Treasury inflation protected securities) 20%
Natural resources 20%
Stocks geared to inflation 20%
15% Real Asset Allocation
Real estate is an investment form with limited liquidity compared to other investments, it is also capital-intensive (although capital may be attained by mortgage leverage) and highly depends on cash flow. Because of these realities it is important that this section of the portfolio does not make up the bulk of the portfolio. You could structure your real estate portfolio in the following way:
Real estate investment trust (REITs) 40%
Direct investments 30%
Private equity real estate 15%
It is however very important to observe that option-like securities are very risky and should be used with extreme caution. This is what brought down the oldest merchant bank in the UK and is what is described by Warren Buffet as financial weapons of mass destruction. Portfolio management should be done as conservatively as possible. This method that the bulk of the portfolio should be strategic and the minority should be tactical. It is also very wise to have ceilings on alpha seeking locaiongs that an institution can pursue and have a waterproof internal control system to curb rogue trading.
