You could diversify even further because of the risks associated with these companies. That's because anything that affects travel will hurt both industries. Statisticians may say that rail and air stocks have a strong correlation. This means you should diversify across the board—different industries as well as different types of companies.
The more uncorrelated your stocks are, the better. Be sure to diversify among different asset classes, too. Different assets such as bonds and stocks don't react the same way to adverse events. A combination of asset classes like stocks and bonds will reduce your portfolio's sensitivity to market swings because they move in opposite directions.
So if you diversify, unpleasant movements in one will be offset by positive results in another. And don't forget location, location, location. Look for opportunities beyond your own geographical borders.
After all, volatility in the United States may not affect stocks and bonds in Europe, so investing in that part of the world may minimize and offset the risks of investing at home. Obviously, owning five stocks is better than owning one, but there comes a point when adding more stocks to your portfolio ceases to make a difference.
There is a debate over how many stocks are needed to reduce risk while maintaining a high return. The most conventional view argues that an investor can achieve optimal diversification with only 15 to 20 stocks spread across various industries. Investors confront two main types of risk when they invest. The first is known as systematic or market risk. This type of risk is associated with every company. Common causes include inflation rates, exchange rates , political instability, war, and interest rates.
This category of risk is not specific to any company or industry, and it cannot be eliminated or reduced through diversification. It is a form of risk that all investors must accept. Systematic risk affects the market in its entirety, not just one particular investment vehicle or industry.
The second type of risk is diversifiable or unsystematic. This risk is specific to a company, industry, market, economy , or country. The most common sources of unsystematic risk are business risk and financial risk. Because it is diversifiable, investors can reduce their exposure through diversification.
Thus, the aim is to invest in various assets so they will not all be affected the same way by market events. Professionals are always touting the importance of diversification but there are some downsides to this strategy.
First, it may be somewhat cumbersome managing a diverse portfolio, especially if you have multiple holdings and investments. Diversification can also be expensive. Having Too Many Individual Stocks. Holding Assets You Don't Understand. The Bottom Line. Key Takeaways With portfolio management, diversification is often cited as a significant factor in reducing investment risk.
However, there is a risk of over diversification, which can create confusion and lead to weaker-than-expected risk-adjusted returns. How many stocks or other financial issues are best to include in the portfolio can vary based on the needs of the individual investor.
Signs of over diversification include owning too many similar mutual funds in the same categories, too many multimanager products, including funds of funds, too many individual stocks, and misunderstanding the risks of privately held non-traded investments.
