金融代写|利率理论代写portfolio theory代考|Types of Asset Allocation

There are at least three types of asset allocation: strategic, tactical, and dynamic. Strategic allocation, as defined by Nobel Prize winner Bill Sharpe (1987), is set based on long-term goals. For example, if you need to set your asset allocation today for the next 30 years, you would be defining a strategic allocation. A fixed strategic allocation would be consistent with constant investment opportunities and risk tolerances. A fixed allocation may not be a good fit for an individual who plans to switch from saving to spending sometime in the future. In practice, strategic allocations are reviewed and revised at least every three to five years.

Tactical asset allocation responds to short-term changes in investment opportunities. Investors who frequently adjust their exposure to stocks, bonds, and cash are called market timers and set their allocations tactically. They seek to profit from short-term movements in the market, expect to change their asset weights in the near future, and may not worry much about the long-term implications of their average weights. Some active allocation managers may define a band around strategic weights, within which weights may be set in the short term but never deviate by so much so that tactical bets overwhelm the strategic allocation. For example, a longterm average target weight of 50 percent stocks with a $\pm 10$ percent band yielding a $40-60$ percent range would incorporate both strategic and tactical allocations.
Dynamic asset allocation is driven by changes in risk tolerance, typically induced by cumulative performance relative to investment goals or an approaching investment horizon. Portfolio insurance, popular in the mid-1980s, was a dynamic allocation strategy. It was designed to replicate the behavior of a put option by constantly adjusting the allocation to stocks based on the market level. This delta hedge was implemented using futures contracts and worked well until market liquidity collapsed in the 1987 crash. Other forms of dynamic allocation include constant proportion portfolio insurance, constant horizon portfolio insurance, and dynamic horizon asset allocation models.

Asset classes are typically defined as groups of securities with similar characteristics. Statistically their constituents exhibit high correlations within each class, but low correlation between the classes. As mentioned previously, stocks, bonds, and cash arc the most common forms of assct classcs; thcy may bc cxpandcd to includc international stocks and bonds, real estate, venture capital, hedge funds, high-yield (junk) bonds, and commodities. The return correlations between the classes are frequently assumed to be stable and offer attractive diversification, on average. However, under some circumstances such as periods of market crises, correlation levels can shift quickly and eliminate diversification benefits. ${ }^{1}$ This occurred in late 2008 when correlations among risky assets (such as equity classes and high-yield bonds) quickly approached 1. Long-term correlation estimates are reported in Exhibit 3.1, illustrating the high correlation between the domestic equity classes and relatively low correlation between equities and government bonds. Investment-grade corporate and lower-quality high-yield bonds exhibit somewhat stronger correlation with equities. Investment-grade corporate bonds are highly correlated with government bonds, but high-yield corporate bonds appear more closely related to equities. Inflation exhibits low correlation with investments, except for very short-maturity Treasury bills.
