is the
in performance, above
the generic beta
of an asset
class. For example, a portfolio manager who outperforms a basic stock market benchmark, such as the S&P 500
index, is said to be providing positive alpha.
Many managers claim to generate alpha by outperforming the market, but they typically only do so for a short
period under specific circumstances. There is a very small list of portfolio managers who became famous
for beating the market for a sustained period of time.
Eventually the winning streaks end, but the debate
continues—which is better, active managers seeking alpha or the generic returns provided by passive beta?
Perhaps the answer lies somewhere in between alpha and beta.
There is a category between active and passive investing
that some have deemed “smart beta.” The term sounds
like an oxymoron, or a contradiction in terms like

actually makes sense. If beta represents generic stock
market performance, then smart beta implies a logical

attempt to improve upon the performance through
an improved methodology.
In other words, smart
beta simply argues that there should be some level of
discretion or screening applied to a basket of securities.
Some investors may favor stocks that are going up
the fastest in a bull market, while others may prefer
stocks that have fallen the least in a bear market. Some
investors prefer stable stocks that pay dividends, while
others would prefer companies to reinvest all of their
earnings for future growth. All of these factors have
merit, depending on the investor’s objective.
This is
where smart beta should be described more accurately
as factor-based investing.
There are many different investment factors that vary
according to the asset class. In the case of stocks,
several factors can be considered such as momentum,
company size (market cap), growth, value, volatility, yield, market correlation, and others. On an individual
basis, any of these factors can provide certain characteristics that may appeal to an investor.
But for many
investors, knowing which factors to apply, and when to apply them, is the challenge.
. Combining multiple investment factors may be a “smarter” approach to smart beta. For investors seeking stock
exposure, without a specific need for any single factor, blending investment factors could make sense. When
identifying drivers of long-term stock returns, two factors with a lot of academic support for outperformance
are value and momentum (Reference: Fama-French Research, University of Chicago Booth School of Business).
Value strategies attempt to identify stocks that seem underpriced relative to their actual financial characteristics.
Whereas, momentum strategies try to identify stocks exhibiting the strongest positive price movement with little
regard to company valuations. It’s easy to understand why these two factors may complement one another.
One
approach tries to find diamonds in the rough while the other focuses on the high fliers.
Of course there is also the question of quality. Value factors have an element of quality screening, but may have
difficulty in determining undervalued stocks from stocks that are low for reasons other than the balance sheet.
Momentum factors are somewhat quality agnostic in that they have little regard for the quality of a company,
favoring the stock’s price movement instead. Again, this explains why these two factors complement one
another.
But perhaps an even “smarter beta” approach would be to apply a quality screen to the entire universe of
stocks while also assessing the value and momentum characteristics.
Quality can be subjective and determining
a good company from a great one can be
difficult—but identifying the bad ones may
be easier. As an analogy, the illustration to
the right shows several apples. It would be
hard to say which of the apples would make
the best pie.
Many of the apples have similar
traits such a rich color, smooth texture
and a bright shine. But before selecting the
ones to use in a pie, it would at least make
sense to throw out the bad ones. There is no
guarantee that the remaining apples will
always give the best result, but having basic
quality standards is at least a logical starting
point.
A similar philosophy can be used for stock
selection.
Quality stocks tend to have
certain traits in common, such as earnings
consistency and a good track record of
dividend payments. Of course there is no way
to tell how well a seemingly good company’s
stock will perform, but looking for an
indication of quality and corporate stability
may provide some initial benefit.
If single factor strategies are called smart
beta, then perhaps combining multiple
factors with a quality screen may be
considered smarter beta? A blended approach
may lead to the exclusion of the deepest
value stocks or some of the fastest moving
momentum stocks, but it may also help to
avoid a few bad apples along the way.
