What are Fractional Shares?
In the traditional world of investing, you had to buy at least one full share of a company. If a single share of Amazon or Berkshire Hathaway cost thousands of dollars, it was out of reach for many.
Fractional Shares break this barrier. They allow you to buy a "slice" of a stock based on the dollar amount you want to invest, rather than the number of shares. If you have $10, you can own $10 worth of any company, regardless of its share price.
Who is it good for?
- New InvestorsStart building a portfolio with as little as $1.
