Relative Strength Turns
T
Identifying the “strongest” is based on measuring the
performance over a predefined time horizon: short-term
(one to three months); intermediate (six to nine months)
and long-term (12 months or greater). The chart to
the right compares the historical growth of short,
intermediate and long-term relative strength models
against the broad equity market S&P 500. Historically,
over long time periods, each of these relative strength
models outperformed the buy-and-hold equity index.

here is plenty of evidence among academia that
supports the potential value of relative strength,
also called momentum, as an investment factor. This
research has shown that, over multiple decades, relative
strength strategies have consistently outperformed the
overall market during bull and bear market cycles.
Relative strength is the measurement of an investment
instrument’s performance relative to another
instrument.
That performance can be measured against
the market, some combination of securities (i.e., sectors)
or across asset classes. A relative strength strategy is
easy to understand: you simply buy only the strongest
performing instruments. When an instrument slips
enough so it’s no longer the strongest, sell it and replace
it with whatever is the strongest among the instrument’s
universe.

However, like many investment approaches, relative strength will sometimes underperform the market, and at other times it may
outperform. Alpha refers to the amount of performance above or below an index.
In this case, the alpha of relative strength (i.e.,
RS Alpha) has shown long-term cyclical trends with significant tops followed by underperformance and bottoms followed by
outperformance, as the chart below illustrates.

Continues on back
. What happens to relative strength when it makes the turn from its highest and lowest points? The relationship between the alpha
that relative strength can generate and the overall market can become significant. Historically, a new bottom occurs every 11
years on average, but in between, relative strength historically turns and establishes a new top within 6 years after the bottom.
Therefore, the longer you hold a relative strength strategy, the less the impact of tops and bottoms can be felt. In the tables below,
we look at the alpha that a relative strength strategy generated for various time periods leading into these bottoms, turns and
tops. In general, relative strength strategies often underperform in the near (1-3 years) term leading into a bottom, and have
historically generated significant positive alpha once it turned from its bottom.
With relative strength bouncing off a low point in
June 2011 and trending upward as of April 2012, today’s investors have the opportunity to take advantage of RS Alpha’s potential.
RS Alpha During Down-Trends
At a bottom, relative strength
generally underperformed the
market in the near term, yet
performance improved with a
longer time horizon.
