We employ a multi-faceted risk management process to
ensure that the portfolio is appropriately constrained
at the security level, sector level, and Barra risk
factor level. In addition, we use RiskGrades
which is a standardized measure of volatility, and
therefore allows "apples to apples" comparisons of the
securities in our portfolio. We also stress test
our portfolio to simulate what-if scenarios in the event
of an extreme market movement. This
multi-dimensional risk management helps to ensure that
the portfolio has minimal chance for generating negative
surprises.
We
also look at other risks:
Valuation Risk
We attempt to reduce valuation or price risk by buying
stocks that are trading at what we believe are
reasonable prices.
Business Risk
To reduce business risk, we look for companies that have
strong balance sheets, high internal rates of return and
excess cash flow. We want to know what the potential
risk is of "permanent capital impairment," i.e., the
likelihood of a business not being able to generate
sustainable returns on assets or, even worse, becoming
insolvent.
