Portfolio completion may be used strategically or tactically to fill a gap in a portfolio.
For example, an investor may have little or no exposure to certain asset classes, market segments or sectors. Wholesale rebalancing to diversify the portfolio or transitioning into a model portfolio may not be possible because of trading restrictions or other issues.
In these cases, ETFs can be used to fill gaps until the portfolio can be rebalanced to the desired allocation. In the illustration, a value ETF fills a gap and increases the diversification of a portfolio that's heavily weighted toward growth stocks.
