Complete Guide to Odd Lot Selling Order and Trading Tips | Essential Investment Strategies for Small Investors in Taiwan

Fractional share trading has become one of the most popular small-investment methods among Taiwanese investors, especially for salaried workers with limited funds. However, many novice investors often overlook a key issue—the order of selling fractional shares—which directly impacts transaction speed and costs. This article provides a comprehensive guide to fractional share trading, including the latest rules for buying and selling, trading hours, fee calculations, and how to optimize your fractional share selling strategy.

What Are Fractional Shares? Why Are Small Investors Enthusiastic About Fractional Trading?

The minimum unit for whole share trading is one lot (1,000 shares), but investors sometimes end up with scattered shares less than 1,000 due to unfilled orders, resulting in fractional shares. A fractional share is any amount between 1 and 999 shares.

Fractional shares arise mainly because: rapid stock price fluctuations cause orders not to fully execute, the transaction volume doesn’t meet the target price, or leftover amounts occur during stock distribution. Since October 2020, when Taiwan Stock Exchange opened intraday fractional share trading, buying and selling fractional shares has become increasingly convenient, no longer limited to after-hours.

For small investors, the biggest advantage of fractional trading is the significant reduction in capital requirements. Investors no longer need to invest thousands of dollars to buy a full lot; they can flexibly purchase a few shares up to hundreds based on their funds. This allows participation in popular stocks while maintaining sufficient liquidity for daily expenses.

Intraday and After-Hours Trading Hours | Priority of Fractional Share Selling Orders

Fractional share trading is divided into intraday and after-hours sessions, each with different rules and order priority:

Intraday Fractional Share Selling Process

Intraday trading coincides with regular stock trading hours. Investors can submit fractional share orders via broker platforms starting at 9:00 AM. Note: during intraday hours, orders must be placed electronically; manual phone orders are not accepted.

Matching during intraday follows “price priority, then time priority.” If you place a sell order at $500, and another investor also places a sell order at $500 but your order was submitted earlier, yours will be matched first. Unfilled orders (e.g., set at too high a price) during intraday will not automatically carry over to after-hours; investors must resubmit orders after hours.

After-Hours Fractional Share Selling Mechanism

After-hours trading runs from 13:40 to 14:30. Investors can place orders electronically or call broker customer service for manual orders. Only one call auction occurs at 14:30. Orders are matched based on the “maximum transaction volume” principle, and any unfilled orders are automatically canceled at 14:30—they do not carry over to the next day.

During after-hours, the order priority is also “price first,” but at the same price, the sequence is randomly assigned by computer, unlike the time priority during intraday. Investors should be aware of this difference.

Dividends and Dividend Rules for Fractional Shares

Fractional Shareholders Are Entitled to Dividends

Legally, fractional shareholders are still considered company shareholders and are entitled to dividends (profit sharing). However, due to the small shareholding, the dividend amount per payout is relatively minor.

Receiving Dividends and Stock Dividends for Fractional Shares

In dividend distribution, fractional parts less than one share can be handled in two ways:

1. Converted into cash and paid directly to shareholders.
2. The company consolidates fractional shares for sale and distributes the proceeds proportionally among fractional shareholders.

Fee Calculation for Fractional Share Trading | Comparison of Broker Promotions

The transaction fee for buying and selling fractional shares is the same as for full shares—0.1425% of the transaction amount. However, brokers set minimum fee standards and offer discounts for online orders to encourage digital trading.

Fee Calculation Example

Suppose an investor buys 200 shares of TSMC (stock code 2330.TW) at a closing price of 1065 NT dollars:

Basic fee: 200 shares × 1065 NT$ × 0.1425% = 303.53 NT$

With a 50% discount from broker promotion: 303.53 NT$ × 50% = 151.77 NT$

Choosing brokers with promotional discounts can significantly reduce trading costs.

How to Make Selling Fractional Shares Easier? Five Strategies to Optimize Selling Priority

Many investors find it difficult to sell fractional shares, especially for less-traded stocks with low liquidity. Orders may remain unfilled for days, requiring multiple days of repeated orders. Here are five strategies to improve success rates:

Strategy 1: Understand the Priority of Selling Orders

As previously mentioned, intraday orders follow “price priority, then time priority,” while after-hours orders follow “price priority, then random order.” To increase chances:

• Intraday: Place your sell order before others at the same price, especially if you want priority during the day.
• After-hours: Since orders are randomly sorted, consider placing your order close to 14:30, using the latest market info, to maximize chances.

Strategy 2: Convert Fractional to Whole Shares

This is the most effective way to speed up sales. For example, if you hold 700 shares of Shin Jin (1582.TW), which is not a hot-traded stock, your fractional sell orders may take a long time to fill. You can:

• Buy an additional 300 shares to make a total of 1,000 shares (one lot).
• Sell the full lot in the more liquid whole-share market.

This approach often results in faster and better-priced transactions, especially if you need quick cash.

Strategy 3: Buy at Limit Up (涨停) Price, Sell at Limit Down (跌停) Price

Since after-hours fractional trading only occurs once at 14:30 with the “maximum transaction volume” rule, investors can leverage this:

• To buy quickly: Place a buy order at the涨停 (limit-up) price; such orders are more likely to be matched.
• To sell quickly: Place a sell order at the跌停 (limit-down) price; similarly, these are more likely to be executed under the maximum transaction rule.

This requires some market judgment and risk tolerance, as selling at跌停 may lead to losses.

Strategy 4: Place Multiple Orders and Adjust Prices

If your fractional shares remain unsold, try:

• Placing an initial sell order at your target price after hours.
• If not filled, lower your sell price by 5-10% and re-enter the order the next day.
• Continue adjusting downward until the order is filled.

This gradual approach can increase the likelihood of sale while avoiding excessive price cuts.

Strategy 5: Observe Market Depth and Trading Volume

Monitor indicators such as:

• Trading volume trends: Increasing volume suggests higher liquidity.
• Bid-ask spread: Narrowing spreads indicate market participation is improving.
• Market news: When a stock becomes a market focus (e.g., news, restructuring), liquidity for fractional shares increases.

Timing your sale during high liquidity periods can significantly improve success.

Minimum Trading Units and Investment Suggestions for Fractional Shares

Stocks are traded in units of 1 share; any order must be in multiples of 1. Investors can consider investing around NT$10,000 per transaction to balance costs and liquidity, as:

• Buying NT$1,000 worth of fractional shares incurs high proportional fees (e.g., 1 NT$ fee on a NT$1,000 purchase is 0.1%), which can significantly eat into returns.
• Larger investments reduce the fee ratio and improve cost efficiency.

Pros and Cons of Fractional Share Trading | Suitable Investors

Advantages

1. Very Low Capital Requirement
Fractional shares allow participation with minimal funds—no need to buy a full lot. With NT$1,000–NT$2,000, small investors, students, or part-time workers can start investing, practicing their investment ideas while preserving cash for daily needs.

2. Suitable for Dollar-Cost Averaging
Fractional trading is ideal for systematic investment strategies. Investors can allocate a fixed amount monthly (e.g., NT$3,000) to buy shares without waiting to accumulate enough for a full lot.

3. More Convenient Trading
With intraday fractional trading now available, investors can check prices and place orders anytime during market hours via mobile apps.

Disadvantages

1. Low Liquidity
Compared to full lots, fractional shares have much lower trading volume, leading to longer wait times for execution, especially for less popular stocks.

2. Higher Relative Costs
Minimum fees (often NT$1–NT$20) can be a large proportion of small trades, reducing profitability. For trades under NT$10,000, fees can significantly impact returns.

3. Trading Limitations
Fractional shares can only be sold; investors cannot buy fractional shares directly from brokers. Also, converting fractional to full shares involves time limits, and if the broker lacks sufficient inventory, the desired quantity may not be available.

Alternative Investment Method for Small Investors: Contracts for Difference (CFD)

If concerned about high fees and liquidity issues in fractional trading, investors might consider CFDs, which are derivative instruments:

• Low Capital Requirement: Margin typically only 5%, so a small amount controls a larger position.
• Transparent Costs: Usually only the bid-ask spread, no commissions.
• High Liquidity: CFDs are traded on deep markets, ensuring quick execution.

Note: CFDs are more suitable for short-term trading and involve daily settlement and overnight interest costs. They do not confer ownership of the underlying stock.

Conclusion | Master the Selling Order Priority for Better Small-Investor Trading

As Taiwan’s financial market continues to develop, fractional share trading has become an excellent entry point for small investors. Compared to traditional full-lot trading, fractional shares require less capital and offer flexible investment options, meeting diverse small-investor needs.

To succeed, investors must understand the order of selling fractional shares and the associated priority rules. During intraday hours, “price first, then time” applies; after-hours, “price first, then random.” Mastery of these rules allows targeted adjustment of selling strategies to improve execution.

Additionally, learning practical techniques such as converting fractional to whole shares and leveraging limit-up/limit-down orders can enhance trading efficiency. Investors should also weigh the pros and cons of fractional trading, assess their risk tolerance, and consider alternative tools like CFDs if liquidity or cost concerns arise.

Most importantly, maintaining a rational investment mindset, avoiding impulsive trades, and understanding the underlying mechanisms will help small investors navigate the market steadily and profitably.
