What Is Micro-Investing?
Micro-investing involves putting small amounts of money—sometimes as little as $1—into investment portfolios. Instead of buying whole shares of expensive stocks, you purchase fractional shares, making it affordable to invest in big names like Apple or Tesla. These apps often use automation, like rounding up your purchases and investing the difference, to make saving effortless.
For U.S. beginners, micro-investing is a low-risk entry point. It eliminates the need for large upfront capital and teaches you the basics of market growth, dividends, and diversification. Plus, with mobile apps, you can manage your investments from anywhere—whether you’re sipping coffee in Seattle or commuting in Chicago.
