Guide to Fractional Share Investing: Mastering Trading Hours, Fees, and Optimal Buy-Sell Strategies

Fractional share trading has become a popular investment avenue for small investors in recent years, allowing them to participate in the stock market with a lower entry barrier. This article will delve into the basic concepts of fractional shares, trading rules, fee structures, and practical buying and selling techniques to help investors conduct fractional share trading more effectively.

Detailed Explanation of Odd Lot Basic Concepts

Odd lots refer to the quantity of stocks that is less than 1000 shares (one lot), with the minimum unit being 1 share. There are usually two common reasons for the occurrence of odd lots:

1. Unfilled Orders: When stock prices fluctuate too quickly or the volume does not reach the target price.
2. Stock Allocation Process: The fractional shares generated during the company's equity distribution.

Fractional share trading allows investors to buy and sell between 1 to 999 shares, providing a more flexible option for investors with limited capital. From an investment structure perspective, fractional share trading can be seen as a more refined method of asset allocation, similar to the token splitting mechanism in the digital asset space.

Analysis of Odd Lot Trading Time and Rules

Starting from October 26, 2020, the fractional share trading mechanism underwent significant upgrades, allowing investors to trade fractional shares during regular trading hours, greatly enhancing trading convenience.

trading time frame

| Time Period | Order Method | Transaction Method | Transaction Order Principle | | --- | --- | --- | --- | | Intra-day Trading 9:00-13:30 | Electronic Orders Only | First Matching at 9:10, then Matching Every Minute via Collective Auction | Price Priority, Time Priority within the Same Price | | After-hours trading 13:40-14:30 | Electronic or telephone manual orders | Single matching conducted at 14:30 via collective bidding | Price priority, random sorting by computer for the same price |

Important Trading Regulations:

• Unfilled orders during trading hours will not automatically transfer to after-hours trading and need to be resubmitted.
• Unexecuted orders after the market close will be automatically canceled and will not be carried over to the next trading day.
• The shareholder rights of odd lot trading are the same as those of whole shares, and they are eligible for dividends and distributions.

The minimum trading unit for odd lots is 1 share, but due to the fee structure, it is recommended that the total investment amount exceeds ten thousand for it to be more economical.

Details on Opening a Margin Account and Fees

Fractional stock trading uses the same trading channel as whole stock trading; you only need to switch to "Fractional Stock Trading" mode on the broker's app order page. The calculation method for fractional stock trading fees is the same as that for whole stock trading, at 0.1425% of the transaction amount, but each broker will set a minimum fee and electronic order discount.

Example of Fee Calculation:

Purchase 200 shares of TSMC (2330.TW, assuming a closing price of 1065 yuan):

• Basic service fee: 200 × 1065 × 0.1425% = 303.53
• If the broker offers a 50% discount: 303.53 × 50% = 151.77 yuan

Comparison of Main Brokers' Commission Fees for Odd Lot Trading:

| Brokerage | Minimum commission for odd lot trading | Electronic order discount | Account opening requirements | | --- | --- | --- | --- | | Fubon Securities | 1 TWD | 1.8 discount | National ID card, second identification document and personal bank account | | Yongfeng Gold Securities | 1 Yuan | 20% off | National ID card, second ID and personal bank account | | KGI Securities | 1 Yuan | 40% off | National ID card, second identification document, personal bank account, and proof of financial capability | | Shin Kong Securities | 1 Yuan | 10% | National ID, Second ID and Personal Bank Account | | Unified Securities | 1 Yuan | 1.68 Discount | National ID Card, Second ID and Personal Bank Account |

Efficient Strategies for Odd Lot Trading

Techniques for Consolidating Small Amounts

For less popular stocks, odd lot trading may face liquidity issues. At this time, the "merging odd lots into whole" strategy can be adopted:

Case Study: Assuming you hold 700 shares of Hsin Chien (1582.TW) and wish to sell, but the odd lot trading volume is low. You might consider buying an additional 300 shares to make a total of 1000 shares (1 lot of whole shares), and then sell through the more liquid whole share market to improve transaction efficiency.

This strategy is similar to liquidity aggregation techniques in the digital asset world, enhancing overall liquidity by combining decentralized assets.

Price Strategy Optimization

After-hours odd lot trading adopts a 14:30 single auction mechanism, which can utilize specific pricing strategies to increase transaction probability:

1. Buying Strategy: If you are certain about buying a specific odd lot, you may consider placing an order at the limit price, increasing the likelihood of execution under the principle of maximum transaction volume.
2. Selling Strategy: If you urgently need to sell your fractional shares, consider placing a limit order at the lower circuit breaker price to increase the chances of a quick transaction.

Market analysis shows that compared to regular limit orders, extreme price strategies can increase the execution rate by approximately 15-20% in after-hours trading with limited liquidity.

Analysis of the Advantages and Disadvantages of Fractional Share Investing

Investment Advantages

1. Lower Investment Threshold: Fractional share trading allows investors to participate in the stock market with less capital, making it particularly suitable for small investors and beginners.
2. Increase Investment Flexibility: Allows for precise control over the amount of funds invested, enabling more detailed asset allocation.
3. Diversification of Investment Portfolio: Access to more high-value stocks increases the diversity of the investment portfolio.
4. Regular Investment Optimization: Suitable as an auxiliary tool for long-term regular investment.

Potential Disadvantages

1. Liquidity Challenge: The trading volume of odd lots is often less than that of whole shares, which may require more time to execute.
2. Relatively high transaction fee costs: Considering the minimum fee settings, the cost-effectiveness of small transactions is relatively poor.
3. Trading Timing Restrictions: The matching mechanism differs from whole shares, which may affect the execution of short-term trading strategies.
4. Trading Process is Restricted: Odd lot trading has specific limitations on the order quantity and timing.

Market Positioning and Alternative Options for Odd Lot Trading

Odd lot trading is mainly suitable for long-term investors and those who wish to participate in the stock market with small amounts of capital. If there are still concerns about the transaction fees and liquidity of odd lot trading, there are other small investment options available in the market:

Contract for Difference (CFD):

• Only a small portion of the margin (usually 5%-10%) is required.
• No need to buy actual stocks, just focus on price changes.
• Most trading platforms charge spreads instead of commissions, making costs more transparent.
• Better liquidity, not subject to restrictions on odd lot trading volume.

Case Comparison: If you buy 5 shares of Google stock at a price of 400 USD, the total expenditure is 2000 USD; if you trade the same quantity through the contract for difference ( with a margin of 5% ), you only need to pay a margin of 100 USD.

Fractional trading is suitable for long-term investors and value investment strategies, while derivatives such as contracts for difference are more suitable for traders seeking to profit from short-term price fluctuations. Investors should choose the most appropriate trading method based on their own risk tolerance, investment horizon, and financial situation.
