These quotes from some consultants and sponsors alike beg the question
of what's going on in the Canadian fixed income market. Is there
any value to active management, or should managers simply index
their assets? In other words, can the bond market be beaten?
When comparing the results of equity and fixed income managers
over the five years ending December 1998, there are two startling
differences. The difference between first and third quartile fixed
income managers is relatively small at 50 basis points, compared
to the difference between first and third quartile Canadian equity
managers at 150 basis points. Bond managers are demonstrating relatively
small value added, in contrast to equity managers. Further, in fixed
income management, a first quartile manager beat the market benchmark
by less than 40 basis points. In contrast, in Canadian equities
first quartile performance resulted in over 150 basis points in
value added against the TSE 300 total return index. Hence, over
the past five years, the payoff for very good fixed income performance
has been relatively small compared to superior Canadian equity results,
albeit in a less volatile asset class. As well, the spread between
first and third quartile bond managers has narrowed in recent years.
Bond managers appear to be having more trouble beating the market.
Exhibit 1 defines and conceptually displays standard fixed income
styles and strategies used by Canadian money managers. Let's review
why some of these strategies have perhaps not performed as well
as active managers would like.
Pricing Anomalies: In the continuous tug-of-war between
efficient and inefficient markets, one of the casualties is pricing
anomalies. Today, most traders are equipped with the tools to ensure
that basic pricing anomalies disappear. In addition, the irony of
pricing anomalies is that the larger the opportunity, the greater
the odds that they will attract the players to eliminate them. In
Canada, the size and sophistication of the market has significantly
increased with the entrance of U.S. "behemoth" brokerage
firms, as well as the establishment of deep pocketed, bank owned
brokerage operations. Hence, pricing anomalies have been reduced.
Finally, the establishment of a new settlement system in mid 1993
through the Canadian Depository for Securities Limited (CDS) significantly
increased the lucidness of the market.
Bond Swapping: Spread traders attempt to take advantage
of spread differentials that appear abnormal relative to historical
experience and expected market conditions. Two key market conditions
help bond swappers: wide spreads and spread volatility. Wider spreads
provide for greater profitability, while volatility creates opportunities
for managers. Until "the great credit crisis" of September
1998, both spreads and spread volatility had been shrinking since
1994, reducing the opportunities to add value through these strategies.
Yield Curve Forecasting: Yield curve forecasters face great
challenges. From a historical perspective, changes in the slope
of the yield curve tend to be both choppy and unpredictable. The
latter point makes good intuitive sense, as forecasting the yield
curve is similar in challenge to calling turns in the market. While
the direction can at times seem obvious, choppiness or missing market
turns can significantly reduce or eliminate value added. Even so,
in a neutral monetary policy regime there is little opportunity
for added value through this strategy.
Interest Rate Anticipators: Exhibit 2 compares the historical
value added versus the volatility of value added for managers using
interest rate anticipation strategies over the four years ending
December 31, 1998. Managers are classified into two categories:
constrained duration managers and aggressive duration managers.
Constrained duration managers allow their duration range to move
plus or minus one year away from the benchmark market, while aggressive
duration managers allow their duration range to move more than plus
or minus one year from the market.To highlight the differences in
the two approaches, we drew ellipses around each of the manager
groups. This allows for visual comparisons between the two groups,
with reduced distraction from all the data points. The ellipse is
constructed so that 95% of each set of data points lies within it,
while keeping the ellipse as small as possible. Inferences can then
be drawn from:
* the relative size of the ellipse;
* the slope of the ellipse; and
* its position relative to other ellipses.The results indicate
that some managers employing rate anticipation strategies have been
able to beat the market. However, on average, aggressive rate anticipators
were not rewarded for the additional risk they took. As pointed
out in a recent insightful fixed income research paper, "even
with some skill at forecasting rates, assuming the strategy depends
on macroeconomic analysis, it is hard to make new interest rate
bets more than roughly once per quarter. Such a strategy involves
very little breadth."1 It is difficult to increase and diversify
the number of independent bets per year applying an interest rate
anticipation strategy. This explains why we flatten the shape of
the excess return to risk curve, for as you move towards full interest
rate anticipation strategies, managers have gained little by taking
on additional duration risk.
How Can We Beat the Fixed Income Market?
Standard fixed income styles and strategies are insufficient alone
to "beat the market." However, fixed income managers can
significantly improve their alpha potential by looking at different
types of bets across sectors.2 This does not mean increasing duration
strategies, but considering and implementing "alternative"
innovative styles and strategies to significantly increase the odds
of beating the market.
The Case Against Indexing
The case against bond indexing and for active investment management
rests on several points, including:
* The Canadian fixed income market is broadening.
* Global opportunities provide for alpha and risk diversification
benefits.
* The yield advantage for patient investors.
The Market is Broadening
A key underlying premise in selecting a passive index strategy is
that the underlying benchmark reflects the opportunity set of the
asset class. However, as Exhibit 3 reveals, the Canadian fixed income
market has begun to broaden out with the development of new sectors
not included in the Index. In addition, negative growth in government
insurance and positive growth in corporate, asset backed and mortgage
backed securities is accelerating this broadening out. As the market
continues to innovate and build breadth, an investor who passively
invests in the fixed income index will not obtain exposure to these
new opportunities. Active management is the only source for such
alpha opportunities.
Global Opportunities
Even with the broadening out of the Canadian bond market, major
bond markets provide further significant breadth and depth of issuance.
For Canadian fixed income managers, the global fixed income arena
provides a much broader array of choice, and consequently opportunities
in the following areas: high yield, sovereign debt, securitized
securities (e.g., mortgage and asset backed), corporates and emerging
markets.
Many managers can implement the following "portable alpha
strategy": employ as a benchmark a broad universe of Canadian
fixed income securities (e.g., DS BARRA or Scotia) while searching
the world for unique additional potential value added or risk diversification
strategies. For example, Greece is a country that has historically
experienced high inflation and fiscal deficits. This caused their
interest rates to be much higher than the "core" EU countries.
In their drive to meet the criteria to join the EMU countries using
the Euro, they have slashed deficits and inflation. Their bonds
have been exceptional performers as this happened. This strong relative
performance was attained even if the Greek currency exposure was
hedged into C$.
Further supporting the case for allowing for a broader opportunity
for Canadian fixed income benchmark investors is the increasing
globalization of fixed income markets. For example, as Europe continues
to integrate into one economic union, we expect the market to develop
new types of securities (e.g., ABS) and a broadening of non-government
bond sectors. These developments and further convergence in world
fixed income markets should provide opportunities for early market
participants.
The Yield Advantage for Patient Investors
Patient investors in corporate and other below AAA securities are
well rewarded in the long term for taking liquidity and credit risk.
Exhibit 4 displays the historical spread between Canadas and Corporates.
As expected, corporates have provided a higher yield, averaging
85 basis points more in yield than similar duration Canadas.
As mentioned, the Canadian fixed income market, like the European
fixed income market, is expected to innovate and evolve over time.
Exhibit 5 displays the current sectors of the Canadian Fixed Income
Market versus the DS BARRA Canadian Bond Market Index Forecast Sector
weights. Canada's fiscal health has significantly improved, leading
the Government to buy back government bonds, a trend that is forecast
to continue in the future. Canadian corporations have also been
tapping the bond market more frequently and this pace is expected
to pick up as well. These two changes should lead to corporate bonds
having a more prominent position in the Canadian marketplace.
We expect both a broadening (e.g. ABS, MBS, swaps and structured
notes) and deepening (e.g. corporates, private placements) of the
sectors in our market.
These changes will provide for further higher yield opportunities
for patient investors. A strategy that deliberately overweights
corporate bonds versus the benchmark should add value over the medium
to long run. If a bankruptcy causes a loss on a corporate bond,
this is not a result of overweighting corporate bonds. This is a
result of bad corporate bond selection.
Multi-Style Multi-Manager is the Only
Way to Go
Our knowledge of successful implementation strategies (i.e. what
works and what doesn't) in fixed income investing has increased
with our experience. As in other asset classes, style risk is significant
and unpredictable. Exhibit 6 displays the best and worst performing
manager styles in fixed income markets since 1990.
Two observations stand out. The market rewards different styles
over time without any predictable pattern. In addition, the return
differential between the best and worst performing styles can be
enormous.
These results strongly indicate that to successfully implement
an active fixed income approach, a multi- style, multi-manager process
should be employed to reduce and systematically control style risk
and enhance returns. Exhibit 7 gives an example of a multi-style
multi-manager fixed income structure.
Conclusion
We opened with the question; Why have fixed income managers recently
found it more difficult to beat the market? While we believe that
the market has indeed become more efficient, fixed income managers
have also been slow to react to the new competitive environment,
contributing to the narrowness in value added results. There is
a compelling case for active fixed income management within the
framework of a multi-style, multi-manager structure. We just need
to be more innovative and proactive in attacking the challenge.

Exhibit 1
1. Indexed: Indexing is a style which matches the manager's
portfolio to that of a specific financial market index, with the
objective of duplicating the general performance of the market in
which it invests.
2. Pricing anomalies: This style attempts to add value
through active valuation and arbitrage trading of mispriced securities.
Rich (or overvalued) bonds which have lower yields than bonds of
similar credit and term are sold, while cheap (or undervalued) bonds
which have higher yields than bonds of similar credit and term are
purchased.
3. Bond swapping (spread trading or sector rotation): A
yield spread strategy involves positioning a portfolio to capitalize
on expected changes in yield spread between sectors. This is done
by varying the percentage 'weights' of different types of bonds
held within the portfolio. A portfolio manager will form an opinion
of the valuation of a specific sector of the bond market, based
on the credit fundamental factors for that area, the yield spread
over Canada bonds, and technical factors such as supply and demand
within that sector. That sector will then be over- or underweighted
in relation to the benchmark index.
4. Yield curve forecasting: This strategy takes into account
the differences in interest rates for various maturity terms and
yield curve shifts. Three types of yield curve shifts are a) Parallel
Shifts b) Twists (flattening or steepening) c) Humps (butterfly
shifts). Two portfolios with the same duration may perform differently
if the yield curve does not shift in a parallel fashion. Therefore,
a portfolio should be positioned to profit the most from an expected
change in the yield curve, based on an economic or market forecast.
5. Interest rate anticipation: This style involves forecasting
interest rates and altering a bond portfolio's duration to take
advantage of that forecast. A basic interest rate anticipation strategy
involves moving between long-term government bonds and short-term
Treasury bills. A portfolio duration longer than the index is desirable
when interest rates are declining, while a portfolio duration shorter
than the index will outperform when interest rates rise.
