Investors building a portfolio for the first time may be wondering how many stocks they should invest in. Diversification certainly plays a role, but it ultimately comes down to the number of assets you’re comfortable monitoring.
There’s no one-size-fits-all approach to investing in the stock market, but most US investors tend to hold 10 to 30 stocks in their portfolio. Investors new to the market may prefer a smaller portfolio of 10 stocks, give or take — while more experienced traders may maintain a portfolio of 30 or more.
In their book, Investment Analysis and Portfolio Management, financial analysts Frank Reilly and Keith Brown suggest the sweet spot lies between 12 and 18 stocks — a range that successfully capitalizes on 90% of the benefits of diversification. Others, like Burton Malkiel, author of A Random Walk Down Wall Street, suggest that investors need closer to 20 stocks to reduce risk by up to 70%.
The more positions you maintain, the more maintenance your portfolio requires, including market research and staying up-to-date on industry news. The bottom line? You need to monitor the performance of everything you purchase. If you’re not willing to keep an eye on it, don’t buy it.
If you’re short on funds and new to the market, there are several investment options with built-in diversification. Each of the following can be purchased through a brokerage account:
When you pour all your money into a single stock, the success of your investments hinges entirely on the performance of a single company. While you can earn potentially higher returns, you may also face equally sizable losses.
Think your investments are safe with blue-chip stocks, like Apple, Wal-Mart or Disney? Think again. No company, regardless of sector, industry or time in business, is risk-free. And that’s because all stocks are exposed to company risk and market risk.
Company risk, or unsystematic risk, is the risk associated with investing in a single company. And while it’s typically more of a gamble to invest in startups and small-cap stocks, there are risks to investing in larger companies, too.
Market risk, or systematic risk, applies to all companies, regardless of size, as some events — like natural disasters and political upheavals — have the potential to impact the entire market.
The best way to insulate your portfolio from potential loss is to diversify your investments, holding multiple stocks across a spectrum of industries. It’s impossible to avoid market risk, but by investing in more than one company, you reduce your portfolio’s company risk exposure.
There are numerous ways to manage your portfolio and reduce the risk of loss.
If you need help building a portfolio from scratch, consider a financial advisor. There are numerous investment platforms that offer portfolio management services, but you’ll pay a fee to access the service — typically a percentage of your total assets.
Your advisor will sit down with you to discuss your investment goals and help you determine your risk tolerance. Once your portfolio is funded, your advisor takes care of the rest. You may meet with your advisor once or twice a year to discuss your investments, but you won’t be actively managing your portfolio. This is an option best suited for hands-off investors.
If you do want to manage your investments but would prefer some guidance before you pull the trigger, consider hiring an investment fiduciary. This person can provide occasional guidance and feedback on your portfolio while leaving the buying and selling process in your hands.
