Investors nationwide have been on edge after the worst annual stock market performance in a decade. China trade war tensions, rising interest rates, and the partial government shutdown have caused more volatility. With these recent swings in the stock market, some investors may notice corroborating shifts in their investment portfolio. Even in volatile markets, significant losses in a conservative or moderative portfolio should raise serious concern. Nearly all investors should have a diversified investment portfolio for protection from long-term losses. Diversification is a capital-preserving risk management method that calls for an investment portfolio to carry a variety of investments within different asset classes, countries, sectors, and companies.
Diversification is essential because correlated securities within the same asset class, sector, and country will tend to follow similar patterns. Meanwhile, selecting securities from different areas will reduce such resulting risk. Investment portfolios should not only include investments that differ by asset class. For example, holding many different investments tied to just the real estate sector is not a diversified portfolio. Common sectors include financial, healthcare, energy, energy, utilities, technology, consumer staples, industrials, materials, real estate, telecommunications, and consumer discretionary. Within each of these sectors, there are many excellent choices.
An investment strategy that includes diversification will, on average, yield higher returns and lower risk than a singular holding. A diversified investment portfolio has a cumulative lower variance in return or risk than its lowest asset. In a properly diversified portfolio, the decline of a few of your holdings should be countered by the state of other unaffected holdings. On the other hand, heavy concentration in one investment will leave your portfolio’s increase or decline entirely dependent on fewer factors. For instance, investing all of your money into one stock in a company that goes under will result in the loss of all your money. Ownership of more types of shares over a long time has tended to produce around 5%-8% in returns historically.
