Real estate sector takeaways for investors
Real estate and the stock market are two of the most effective ways to build wealth. For investors who want to diversify their portfolios, real estate companies are a straightforward way to gain exposure to real estate through a brokerage account.
REITs, in particular, are a popular investment option. They make up eight out of 10 of the largest real estate companies by market cap. Not only is it easy to buy and sell REITs, but investors can also receive sizable dividends, since REITs are required to distribute at least 90% of taxable income as dividends.
REITs and other real estate companies also tend to be less volatile than the overall stock market. Whether you're looking for greater diversification or more stability in your portfolio, investing in real estate could help you achieve it.
