The 6 Most Common Portfolio Protection Strategies
The key to successful long-term investing is the preservation of capital. Warren Buffett, arguably the worlds greatest investor, has one rule when investing - never lose money. This doesnt mean you should sell your investment holdings the moment they enter losing territory, but you should remain keenly aware of your portfolio and the losses youre willing to endure in an effort to increase your wealth. While its impossible to avoid risk entirely when investing in the markets, these five strategies can help protect your portfolio.
Diversification
One of the cornerstones of Modern Portfolio Theory (MPT) is diversification. In a market downturn, MPT disciples believe a well-diversified portfolio will outperform a concentrated one. Investors create deeper and more broadly diversified portfolios by owning a large number of investments in more than one asset class, thus reducing unsystematic risk. This is the risk that comes with investing in a particular company as opposed to systematic risk, which is the risk associated with investing in the markets generally.
Non-Correlating Assets
According to some financial experts, stock portfolios that include 12, 18 or even 30 stocks can eliminate most, if not all, unsystematic risk. Unfortunately, systematic risk is always present and cant be diversified away. However, by adding non-correlating asset classes such as bonds, commodities, currencies and real estate to a group of stocks, the end-result is often lower volatility and reduced systematic risk due to the fact that non-correlating assets react differently to changes in the markets compared to stocks; when one asset is down, another is up.
Ultimately, the use of non-correlating assets eliminates the highs and lows in performance, providing more balanced returns. At least thats the theory. In recent years, however, evidence suggests that assets that were once non-correlating now mimic each other, thereby reducing the strategys effectiveness.
