Recently, many friends around me have asked if fractional shares are easy to sell. Honestly, that's a good question because many people don't think this through when buying fractional shares, and as a result, they end up losing money due to liquidity issues.

First, let’s start with the conclusion: popular stocks' fractional shares are still relatively easy to sell, but for less popular stocks, it can be quite difficult. I’ve personally experienced this pitfall—holding 700 shares of a non-mainstream stock, only to find during trading that there’s no one willing to buy, and I had to wait until after hours or the next day to relist. That’s when I truly realized how real the liquidity limitations of fractional shares can be.

Since the Taiwan Stock Exchange opened up intraday fractional share trading in 2020, it has indeed become more convenient. Now, trading is available from 9:00 AM until 1:30 PM, with an after-hours window from 1:40 PM to 2:30 PM. But convenience aside, the problem is that trading volume for less popular stocks’ fractional shares is naturally low, and matching buy and sell orders often takes more time. Sometimes, it can even take a whole day to complete a trade.

To improve the chances of selling fractional shares, I’ve figured out a few tricks. The first is “convert fractional to whole,” which means buying more shares to make up a full lot, then selling via whole-share transactions, since liquidity for whole shares is much better than for fractional ones. The second is placing limit orders at the limit-down price during after-hours trading, using the maximum transaction principle to increase the likelihood of execution. Although this means selling at a worse price, it at least guarantees an exit.

A word of caution: the transaction fees for fractional shares are actually an invisible cost. The fee calculation for buying and selling fractional shares is the same as for whole shares—0.1425%—but brokers usually set a minimum fee, often starting at NT$20. I calculated that if you only buy 200 shares of TSMC, the fee would be over NT$300. Even with a 50% discount, it’s still over NT$150, which is a significant burden for small investments. Different brokers offer varying discounts: Fubon Securities and E.SUN Securities have lower discounts (around 18% to 20%), while Shin Kong Securities offers a 10% rate, and many have a minimum fee of NT$1.

In summary, is it easy to sell fractional shares? It depends on the stock. Popular stocks are manageable, but for less popular ones, you need to put in some effort. Also, although the capital requirement for fractional shares is low, the fee ratio isn’t negligible. Think carefully before buying—don’t let the fees eat into your profits. If liquidity and costs are major concerns, CFDs (Contracts for Difference) are another option. You only need to put up margin to trade stock price differences, with no additional commissions, transparent spreads, but keep in mind that CFDs are more suitable for short-term trading, and overnight positions incur interest.

Investing doesn’t have an absolute good or bad—what matters is understanding the characteristics of each tool and choosing based on your needs and risk tolerance. Fractional shares lower the entry barrier for small investors, but you still need to weigh liquidity and costs carefully.
