Get More for Your Money
With fractional shares you can divide your investments among more stocks to achieve a more diversified portfolio, and put small cash balances to work quickly to maximize potential returns!
What Are Fractional Shares?
Fractional shares represent portions of a whole share of a company’s stock or an exchange-traded fund (ETF). Instead of purchasing an entire share, investors can buy a fraction, allowing them to invest amounts that align with their financial goals. For example, if a single share costs $100, an investor with $50 can acquire 0.5 shares. This approach makes higher-priced securities accessible to a broader audience.
What are the Benefits of Fractional Shares?
The benefits of fractional shares trading include:
Accessibility to Higher-Priced Stocks
Investors can own portions of expensive stocks or ETFs without needing substantial capital.
Portfolio Diversification
Fractional shares trading allows investors to diversify their portfolios more effectively, helping to diversify risks.
Efficient Use of Capital
Fractional shares trading enables the full utilization of available funds, minimizing idle cash and maximizing potential returns.
Facilitation of Dollar-Cost Averaging
Investors can consistently invest in set amounts over time, smoothing out the effects of market volatility.
