Introduction: The Fractional Share Problem for Beginners
This one’s been on my radar for a while now.

High share prices and rigid purchase requirements often discourage beginners from entering the stock market. Fractional shares—allowing investors to buy less than a full share—are a fintech innovation designed to solve this barrier.
This article analyzes two popular platforms offering fractional shares: Robinhood and Fidelity. We break down how each addresses common beginner frustrations, comparing their features, fees, and usability.
Key Takeaways:
- Fractional shares make stock investing affordable for beginners.
- Robinhood offers commission-free trades with simple fractional investing but limited account types.
- Fidelity provides fractional shares with robust research tools and retirement options but has a minimum $1 investment.
- Choosing the right platform depends on your investing goals and comfort with financial tools.

The Problem: Barriers for Beginner Investors
Many beginner investors face these key challenges:
- High stock prices: Some stocks cost hundreds or thousands of dollars per share.
- Limited funds: New investors often have small amounts to invest, making full shares inaccessible.
- Complex platforms: Beginners may find traditional brokerages overwhelming.
- Fees and commissions: These can eat into small investment amounts.
Fractional shares emerged as a solution to these issues, but not all fractional share offerings are created equal.

Solution 1: Robinhood Fractional Shares
What It Is
Robinhood allows users to buy fractional shares with as little as $1. It supports over 7,000 US stocks and ETFs, enabling investors to diversify without large capital.
Why It Works for Beginners
- Commission-free trades: No fees lower the cost of entry.
- Simple app interface: The user-friendly mobile app reduces learning curves.
- Instant deposits: Enables quick investing after funding your account.
How to Implement
- Open a Robinhood account online or via app.
- Deposit at least $1 to start fractional investing.
- Search for desired stock, select “Buy Fractional Shares,” and enter your investment amount.

Solution 2: Fidelity Fractional Shares (Stocks by the Slice)
What It Is
Fidelity offers fractional shares through its “Stocks by the Slice” program, allowing investments starting at $1 in thousands of stocks and ETFs.
Why It Works for Beginners
- Reputation and security: Fidelity is an established brokerage with strong regulatory oversight.
- Comprehensive research tools: Beginners can access educational resources and detailed stock data.
- Retirement accounts supported: Fractional shares can be purchased in IRAs, which Robinhood does not offer.
How to Implement
- Open a Fidelity brokerage or IRA account online.
- Fund your account (minimum $1 to buy fractional shares).
- Navigate to Stocks by the Slice, select the stock, and specify your investment amount.

Solution 3: Choosing Based on Your Investing Goals
Not all fractional share platforms suit every investor. Consider:
- Goal: For casual investing and ease of use, Robinhood’s app is appealing.
- Long-term planning: Fidelity supports retirement accounts and offers extensive research.
- Cost sensitivity: Both platforms provide commission-free trades, but Fidelity has no account minimums beyond $1.
Comparison Table: Robinhood vs Fidelity Fractional Shares
| Feature | Robinhood | Fidelity |
|---|---|---|
| Minimum Investment | $1 | $1 |
| Commission Fees | $0 | $0 |
| Account Types | Individual taxable accounts | Taxable, IRAs, custodial accounts |
| Number of Stocks/ETFs | ~7,000 | Thousands (including Fidelity funds) |
| Mobile App | Highly rated, beginner-friendly | Robust with research tools |

Stick with me here — this matters more than you’d think.
Conclusion
Fractional shares remove the high price barrier for beginner investors, making stock market access more inclusive. Robinhood excels in simplicity and instant access, ideal for those prioritizing ease of use.
Fidelity, on the other hand, offers fractional shares within a comprehensive investing ecosystem, better suited for those aiming toward long-term goals and retirement savings.
Choosing between them depends on your investing priorities: quick, simple investing or a broader, research-driven approach with retirement options.
