How to Use Sector ETFs to Create a Diversified Stock Portfolio

(Click on the image to enlarge)

The highly correlated sector ETFs -- XLB, XLF, XLI, XLK, XLV and XLY -- would make the portfolio an undiversified and aggressive one, while the addition of XLP (less correlated), GDX (uncorrelated) and XLE (negatively correlated) would help reduce risk and make it a more diversified one.

The graph demonstrates, while XLK and XLP moved in tandem initially, they significantly diverged later in the year, suggesting that the longer holding period is equally important in reaping the true benefits of diversification.

Ideally, in order to capture any meaningful shifts in ETF relationships, researchers should run this matrix in three phases: short-term (recent 30 days), medium-term (6 months) and long-term (9-12 months).

Consult your Registered Rep, RIA or Financial Planner for an appropriate asset allocation model and the potential holdings therein.
