Ideally, one looks forward to an optimal portfolio, a portfolio which provides maximum potential returns for a given level of risk. This is where the “Right Asset Allocation” comes into the picture.
Studies show that asset allocation explains about 90% of the period-to-period variability of a portfolio. Extended research also reveals that about 40% of the return variation between funds is due to asset allocation, with the balance due to other factors. But because the average of all investors is the market itself, with good asset managers and bad ones cancelling each other out, asset allocation ultimately accounts for 100% of the absolute level of returns for a portfolio.
Asset allocation thus becomes one of the most important principles of portfolio construction and one of the primary drivers of portfolio performance. By being in the market, and doing a strategic asset allocation across a variety of investments, investors can reduce portfolio volatility and improve performance, as different asset classes may outperform at different times.
How do ETFs support asset allocation?
For asset allocation to work its best, each asset class must be accurately reflected within a portfolio, and that’s where Exchange Traded Funds, or ETFs, play an important role. An ETF provides a true representation of an asset class, tracking the performance of a specific index, such as equity, bond or commodity index, mirroring its returns.
ETFs give investors easy and efficient access to:
- Different asset classes (equity, fixed income and commodities).
- Various markets (domestic, international, and emerging).
- Different market segments (sectors and themes across asset classes).
Hence ETFs play a crucial role for investors looking to implement their optimal asset allocation model as accurately as possible.
Some popular known strategies used to build portfolios through ETFs are:
- Low cost long index exposure – ETFs are known for being one of the lowest cost exposure to the indices at large.
- Core and satellite investment strategies – ETFs allow altering asset allocation in a single trade, maintaining broad-based index ETF as their core and moving to more strategy based ETFs as satellite exposure.
- Sector rotation and tactical allocation – ETFs are used to add or be overweight in specific markets, sectors or industries to a core portfolio.
- Portfolio completion – allows investors to fill gaps in a portfolio in specific asset classes or sectors.
Hence, one of the most popular uses of index based ETFs these days is plugging them into asset-allocation models and many investors have already started utilising low-cost diversified ETFs as their portfolio building blocks.
