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.
Fractional Shares vs Whole Shares Comparison1
| Fractional Shares | Whole Shares | |
|---|---|---|
| Ability to transfer shares | Fractional shares cannot be transferred in or out of IBKR. Instead, you can close your fractional share positions and transfer out the proceeds. (Standard fractional share trading commissions will apply.) | Whole shares can be transferred in and out of IBKR (provided there are no restrictions on the shares in question.) |
| Account availability | IE: Fractional shares are available for all account types. UK: Fractional shares are available for all account types except ISA and Junior ISA accounts. | Whole shares are available for all account types. |
| Capacity | An IBKR affiliate will generally act as the counterparty in fractional share trades and will execute the trade as principal or riskless principal. | Orders for whole shares may be handled in an agency capacity or may be executed by an IBKR affiliate acting as principal. |
| Commissions | Fractional share commissions may be different to the commissions that apply to whole shares. | Whole shares are subject to standard IBKR commissions. |
| Corporate actions | You cannot make voluntary elections on corporate actions regarding fractional shares. You will participate in any stock splits, mergers or other mandatory corporate actions. | You will be able to make voluntary elections on corporate actions with respect to whole shares and participate in any stock splits, mergers or other mandatory corporate actions. |
