Introduction To Tactical Asset Allocation

Tactical asset allocation is an active investment strategy that involves making short-term adjustments to strategic asset allocations based on forecasts of expected returns for different asset classes. Tactical asset allocation is based on the belief that markets are not perfectly efficient and that it is possible to identify and exploit short-term mispricing or trends in asset prices. The goal of tactical asset allocation is to add value by increasing returns when markets are favorable and reducing risk when markets are unfavorable. Tactical asset allocation is a form of market timing, but it is distinct from other forms of market timing in that it operates at the asset class level rather than the individual security level.

The fundamental premise of tactical asset allocation is that asset class returns are predictable to some degree over short to medium time horizons. This predictability can be exploited by adjusting asset allocations to overweight asset classes that are expected to perform well and underweight asset classes that are expected to perform poorly. The predictability may arise from various sources, including market inefficiencies, investor sentiment, or structural factors. Tactical asset allocation is distinct from strategic asset allocation, which is based on long-term expectations and is not intended to be adjusted frequently. The distinction between tactical and strategic asset allocation is important, as tactical asset allocation involves active management, while strategic asset allocation involves passive management.

Tactical asset allocation requires a systematic process for forecasting asset class returns and for determining the appropriate adjustments to the asset allocation. The process should be based on objective criteria and should be implemented consistently over time. The forecasts may be based on fundamental analysis, technical analysis, or quantitative models, and the adjustments should reflect the investment manager’s conviction in the forecasts. The process should also include risk management controls to limit the potential for losses from incorrect forecasts.

Tactical asset allocation is commonly used by institutional investors, such as pension funds, endowments, and foundations, as well as by mutual funds and other investment vehicles. However, the evidence on the effectiveness of tactical asset allocation is mixed. Some studies have found that tactical asset allocation can add value when implemented by skilled managers, while other studies have found that tactical asset allocation has added little value on average. The mixed evidence suggests that the success of tactical asset allocation depends on the skill of the investment manager and the quality of the forecasts. Investment managers who have a disciplined and systematic approach to tactical asset allocation are more likely to be successful.

The implementation of tactical asset allocation requires attention to transaction costs, which can erode returns over time. Frequent adjustments to the asset allocation can generate significant transaction costs, including commissions, bid-ask spreads, and market impact. Investment managers should minimize transaction costs by using low-cost execution methods and by trading efficiently. The costs of tactical asset allocation should be weighed against the expected benefits, and adjustments should only be made when the expected benefits exceed the costs.

Valuation-Based Tactical Strategies

Valuation-based tactical strategies involve adjusting asset allocations based on measures of market valuation. The rationale for valuation-based strategies is that asset class returns tend to mean-revert over time, with high valuations associated with lower future returns and low valuations associated with higher future returns. By adjusting allocations based on valuation measures, investors can increase returns by overweighting assets that are cheap and underweighting assets that are expensive. Valuation-based strategies are grounded in the fundamental principle that the price of an asset should reflect its intrinsic value, and deviations from intrinsic value provide opportunities for profit.

Common valuation measures used in tactical asset allocation include the price-to-earnings ratio, which measures the price of a stock relative to its earnings; the price-to-book ratio, which measures the price of a stock relative to its book value; the dividend yield, which measures the dividend income relative to the price; and the cyclically adjusted price-to-earnings ratio, which measures the price of a stock relative to its average earnings over the past ten years. These valuation measures can be calculated for individual asset classes and compared with historical averages to assess whether the asset class is cheap or expensive. For example, a price-to-earnings ratio above the historical average suggests that the asset class is expensive, while a price-to-earnings ratio below the historical average suggests that the asset class is cheap.

Valuation-based tactical strategies are based on the assumption that asset class returns mean-revert over time. Mean reversion is the tendency for returns to return to their long-term average after deviating from it. Mean reversion is a well-documented phenomenon in financial markets, particularly at longer time horizons. However, mean reversion is not always reliable, and there can be long periods when valuations remain elevated or depressed. The length of these periods can vary, and investors must be patient when implementing valuation-based strategies.

The implementation of valuation-based tactical strategies involves comparing the current valuation of an asset class with its historical average. If the current valuation is significantly above the historical average, the asset class is considered expensive, and the allocation should be reduced. If the current valuation is significantly below the historical average, the asset class is considered cheap, and the allocation should be increased. The magnitude of the adjustment depends on the degree of deviation from the historical average. For example, an investor might reduce the allocation to equities by 5 percent for every 10 percent that the price-to-earnings ratio exceeds its historical average.

Valuation-based tactical strategies are popular among value-oriented investors who believe in the principle of mean reversion. However, these strategies can be challenging to implement, as valuations can remain elevated or depressed for extended periods. During the dot-com bubble of the late 1990s, valuations remained elevated for several years, and investors who reduced their equity allocations based on valuation measures would have missed significant gains. Similarly, during the global financial crisis of 2008, valuations remained depressed for several years, and investors who increased their equity allocations based on valuation measures would have experienced significant losses in the short term.

Momentum-Based Tactical Strategies

Momentum-based tactical strategies involve adjusting asset allocations based on past returns. The rationale for momentum-based strategies is that asset class returns tend to persist over short to medium time horizons, with assets that have performed well in the recent past continuing to perform well in the near future. By adjusting allocations based on past returns, investors can capture momentum trends. Momentum-based strategies are grounded in the observation that markets exhibit persistence, with trends often continuing in the same direction.

Momentum is a well-documented phenomenon in financial markets, with evidence of momentum in various asset classes, including equities, fixed income, commodities, and currencies. The momentum effect is one of the most robust anomalies in finance and has been incorporated into many investment strategies. The momentum effect is typically measured over time horizons of three to twelve months, with momentum strategies generating positive returns over these horizons. The momentum effect is often attributed to investor herding, overreaction, and underreaction to new information.

Momentum-based tactical strategies involve calculating the past returns of different asset classes over a specific time horizon, such as six months or twelve months, and then overweighting the asset classes with the highest returns and underweighting the asset classes with the lowest returns. The implementation may involve ranking the asset classes by past returns and then allocating more to the top-ranked asset classes and less to the bottom-ranked asset classes. For example, an investor might allocate 5 percent more to the top-ranked asset class and 5 percent less to the bottom-ranked asset class.

Momentum-based tactical strategies are popular among trend-following investors who believe in the persistence of market trends. However, these strategies can be challenging to implement, as momentum can reverse abruptly, and there can be periods when momentum strategies underperform significantly. Momentum strategies are also subject to high turnover, which can generate significant transaction costs. The implementation of momentum-based strategies requires careful attention to transaction costs and risk management.

Momentum-based strategies can be combined with valuation-based strategies to create a diversified tactical approach. This combination allows investors to benefit from both mean reversion and momentum persistence. The combination is often referred to as a “dual-momentum” approach, which uses both time-series momentum and cross-sectional momentum to make asset allocation decisions. The dual-momentum approach has been shown to improve risk-adjusted returns relative to single-factor approaches.

Economic-Based Tactical Strategies

Economic-based tactical strategies involve adjusting asset allocations based on forecasts of economic conditions. The rationale for economic-based strategies is that different asset classes perform differently under different economic conditions. For example, equities tend to perform well during periods of economic expansion, while fixed income tends to perform well during periods of economic contraction. By adjusting allocations based on economic conditions, investors can improve returns. Economic-based strategies are grounded in the relationship between the economy and financial markets, with different asset classes exhibiting different sensitivities to economic factors.

Common economic indicators used in tactical asset allocation include GDP growth, which measures the growth of the economy; inflation, which measures the rate of price increases; interest rates, which affect the cost of borrowing and the return on fixed income investments; and unemployment, which measures the health of the labor market. These indicators can be used to forecast the direction of the economy and to adjust asset allocations accordingly. For example, if GDP growth is expected to accelerate, investors may increase their allocation to equities, which tend to benefit from economic growth. If inflation is expected to rise, investors may increase their allocation to inflation-protected assets, such as Treasury Inflation-Protected Securities.

Economic-based tactical strategies are based on the relationship between economic conditions and asset class returns. This relationship is well-documented and forms the basis for the business cycle approach to asset allocation. According to the business cycle approach, different asset classes perform best at different stages of the business cycle. Equities tend to perform well during the early and middle stages of the expansion, while fixed income tends to perform well during the contraction. The business cycle approach provides a framework for adjusting asset allocations based on the stage of the economic cycle.

The implementation of economic-based tactical strategies involves forecasting economic conditions and adjusting asset allocations based on the forecasts. The forecasts may be based on leading economic indicators, which tend to change before the overall economy; coincident indicators, which change at the same time as the economy; or lagging indicators, which change after the economy. The forecasts are then used to determine which asset classes are likely to perform well in the expected economic environment.

Economic-based tactical strategies are popular among macro-oriented investors who believe in the importance of economic factors for investment performance. However, these strategies can be challenging to implement, as economic forecasting is difficult, and there can be significant lags between changes in economic conditions and changes in asset prices. The implementation of economic-based strategies requires careful attention to the timing of adjustments and the accuracy of forecasts.

Dynamic Asset Allocation Strategies

Dynamic asset allocation involves making adjustments to asset allocations based on changes in the investor’s circumstances or market conditions. Dynamic asset allocation is a broader concept than tactical asset allocation, as it encompasses both short-term and long-term adjustments to asset allocations. Dynamic asset allocation is based on the observation that an investor’s optimal asset allocation changes over time as their circumstances and market conditions change. The dynamic approach recognizes that investors are not static and that their needs and preferences evolve over time.

Lifecycle asset allocation is a common form of dynamic asset allocation that adjusts the asset allocation based on the investor’s age or time horizon. Lifecycle asset allocation is based on the observation that younger investors have a longer time horizon and greater ability to recover from losses, allowing for a higher equity allocation. Older investors have a shorter time horizon and lower ability to recover from losses, requiring a higher fixed income allocation. Lifecycle asset allocation is widely used in retirement planning, with many target-date funds using this approach.

Target-date funds are a common implementation of lifecycle asset allocation. Target-date funds automatically adjust the asset allocation as the target date approaches, reducing the equity allocation and increasing the fixed income allocation over time. Target-date funds are widely used in retirement plans and provide a simple way for investors to implement lifecycle asset allocation. However, target-date funds are not appropriate for all investors, as they do not account for individual differences in risk tolerance and financial circumstances.

Dynamic asset allocation can also be based on the investor’s wealth or risk tolerance. Investors with higher wealth may have greater ability to absorb losses and can therefore maintain a higher equity allocation. Investors with lower wealth may have lower ability to absorb losses and should maintain a lower equity allocation. Similarly, investors with higher risk tolerance can maintain a higher equity allocation, while investors with lower risk tolerance should maintain a lower equity allocation. Dynamic asset allocation should be tailored to the specific needs and circumstances of the investor.

Dynamic asset allocation can also be based on market conditions, such as changes in expected returns, risks, or correlations. For example, if the expected return of equities decreases relative to fixed income, the investor may reduce their equity exposure and increase their fixed income exposure. If correlations between asset classes increase, the diversification benefits of the portfolio may decrease, requiring adjustments to the asset allocation. Dynamic asset allocation should be based on a systematic process that specifies the conditions that trigger adjustments to the asset allocation.

Implementation And Challenges

Implementing tactical and dynamic asset allocation requires a systematic process for forecasting returns, determining the appropriate adjustments, and executing the adjustments. The process should be based on objective criteria and should be implemented consistently over time. The forecasts may be based on fundamental analysis, technical analysis, or quantitative models, and the adjustments should reflect the investment manager’s conviction in the forecasts. The process should also include risk management controls to limit the potential for losses from incorrect forecasts.

The implementation of tactical and dynamic asset allocation also requires attention to transaction costs, which can erode returns over time. Frequent adjustments to the asset allocation can generate significant transaction costs, including commissions, bid-ask spreads, and market impact. Investment managers should minimize transaction costs by using low-cost execution methods and by trading efficiently. The costs of tactical and dynamic asset allocation should be weighed against the expected benefits, and adjustments should only be made when the expected benefits exceed the costs.

Tactical and dynamic asset allocation also face several challenges. First, forecasting asset class returns is difficult, and even skilled managers may make forecasting errors. The uncertainty of forecasts means that tactical and dynamic asset allocation is inherently risky. Second, timing the market is challenging, and investors may miss the best periods of performance if they are not invested in the right asset classes. The cost of being out of the market during periods of strong performance can be significant. Third, tactical and dynamic asset allocation can be costly to implement, particularly if the adjustments are frequent. The costs can erode the benefits of the adjustments. Fourth, tactical and dynamic asset allocation can be difficult to communicate to clients, who may not understand the rationale for the adjustments. The lack of understanding can lead to client dissatisfaction and redemptions.

Despite these challenges, tactical and dynamic asset allocation remain important tools in investment management. When implemented effectively, tactical and dynamic asset allocation can add value by increasing returns and reducing risk. However, investment managers must be aware of the limitations and use these tools appropriately. The success of tactical and dynamic asset allocation depends on the skill of the investment manager and the quality of the forecasts.
