What is TAA?




Exists since early-to-mid- 80-ies.
By now $100-200 bln are under management by TAA
managers
A TAA managers’s investment objective is to obtain
better-than-expected return with (possibly) lower-thanbenchmark volatility by forecasting the returns of two or
more asset classes and varying asset class exposure in
systematic manner (Phillips, Rogers & Capaldi, 1996)
Can TAA funds be interpreted as stand-alone asset
class?

How to do it?
We need a model that explains the
connection between today’s variables and
tomorrow returns.
 Candidates: economic business cycle
variables and Jan. Effect.

Evaluation of Recent
Recession




In July 2000, the Yield Curve inverted forecasting
recession to begin in June 2001.
Official NBER Peak is March 2001 (Yield Curve within
one quarter accurate).
In March 2001, the Yield Curve returned to normal
forecasting the end of the recession in November 2001.
On July 17, 2003 the NBER announced the official end of
the recession was November 2001.

Current Situation: Economic growth
•The economy expanded at an annual pace of 4.1%, the most in
more than a year, according to the median estimate of 81
economists surveyed by Bloomberg News. The Commerce
Department last month calculated the growth rate at 3.4%.
• But the outlook for the second half of 2007 has soured in recent
weeks as the subprime mortgage crisis has restricted access to
credit. The Federal Reserve this month said risks to growth had
``increased appreciably'' and economists at JPMorgan and
Lehman are among those that have reduced forecasts.
•There are growing signs of a housing slowdown; new home
sales down, housing prices down, and homeowners with ARMs
facing much higher interest rates.

Current Situation
Inflation perceptions. The long-term rate is a combination of
expected inflation, expected real interest rates and an
inflation risk factor. Long-term inflation expectations have
decreased mainly due to the glut of cheap labor resulting
from globalization.
Tactical Asset Allocation
22
3/21/2016
Current Situation
Strong buying of long-term bonds by foreigners. For the past
few years, strong buying by Asian central banks have
pushed up the Treasury bond prices. However, there is a
debate as to whether this has had a large impact on bond
prices. In addition, this buying has flattened out recently. A
recent Fed study estimated that the foreign buying pushed
yields down by 150bp. Subprime crisis does not end
buying of T-debt by foreigners. Demand for 5yr TB last
week was very high.
Tactical Asset Allocation
23
3/21/2016
Current Situation
Hedge funds. There has been a recent increase in demand for
U.S. bonds from the Caribbean area indicating hedge fund
activity. With long-rates above short rates, many managers
do “carry trades” (borrow short-term and buy long-term
bonds hoping the relation between rates remains stable).
As the term structure flattens, many of these managers
increase their leverage which means more buying pressure
on the long-term bonds.
Tactical Asset Allocation
24
3/21/2016
Current Situation
Demographic forces. As the population ages, more money is
allocated into fixed income and long-term bond yields may
decrease.
Inflation risk. The long-rate rates contain expected inflation,
expected real rates and an inflation risk factor. It is widely
perceived that inflation risk (an unexpected episode of
inflation turbulence) has decreased.

How important are global factors?




Based on Ferson-Harvey RFS95
Question here is: what is more important, local or global
factors for predictability of asset returns.
Global Informational variables: : ”old friends”: 1 mo t-bill, div.
Yield on MSCI World index, spread between 10yr and 3 mo Tbills, Eurodollar/US treasury spread, lagged market return,
January dummy.
Local informational variables: Country x div. Yield, 30-day tbill rate, term spread, lagged MSCI country x market return.

What about currency risk premium?
Currency specificiyy: zero-sum game
 Dumas-Solnik: currency risk premia exists.
It is time-varying and predictable

Caveats:

Data snooping
– Foster, Smith and Whaley (98): by choosing to
max R2 via choice of instruments one can get
significance when there is none.
– Not clear how to use as list of instruments already
exists...

In-sample vs. Out-of-sample validation

Caveats(2)
Statistical biases: autocorrelation,
heteroscedastisity (via Monte-Carlo
simulations).
 Non-normality, excess skewness and kurtosis

How to deal with statistical issues?

Bootstrap methodology:
–
–
–
–
Form empirical distribution of returns
Generate time series of returns (length T).
Perform the regression of interest
See how many times there exists significance
on level a.

Survey Background

Graham/Harvey: Survey CFOs every quarter



Q2 2000 through Q4 2003 (15 quarters)
Current survey attracts about 400 respondents
Why CFOs?
– We know from previous surveys and interviews that the
CFOs use the risk premium for their capital budgeting
– Hence, they have thought hard about risk premium
– Should not be biased the way that analyst forecasts might
be

Conclusion:
TAA can be an important tool in asset
allocation methodology.
 It is based on time variation of real
economic risk premia.
 Selection of predictors is important.
 We are still in ”top-down” paradigm.
 Devil is in the details= implementation
matters.
