Recently, many friends around me have started to consider investing in U.S. stocks, but they don't want to open overseas accounts directly, so discretionary委託 (D委託) has become the most common option people ask about. Actually, I also use D委託 to buy U.S. stock ETFs, so today I want to share my experience.

D委託, simply put, means you place orders overseas through a Taiwanese broker on your behalf. The official name is "Foreign Securities Trading on Behalf of Clients," which sounds complicated, but the concept is very simple. You open an account with a domestic broker, and they then委託 (delegate) your orders to overseas partner brokers to trade on U.S. exchanges. Because the order goes through two layers of委託, it's called "discretionary委託."

I think the biggest advantage of D委託 is convenience. No need to handle foreign exchange yourself, no worries about overseas accounts, and dividends are directly transferred back to your TWD account. If you're a long-term investor with a sizable amount of capital and infrequent trading, D委託 is actually sufficient. However, the drawbacks are also obvious: higher transaction fees and limited product options.

Speaking of fees, this is what I care about most. The委託 fee for D委託 is roughly 0.1% to 1% of the transaction amount, with a minimum fee usually between $25 and $50. Recently, some brokers have started reforming; for example, Cathay Securities has already eliminated the minimum fee. Besides委託 fees, you also need to consider costs like U.S. exchange fees, SEC fees, etc. Buying U.S. stocks is relatively cheap, but if you buy Hong Kong or mainland Chinese stocks, fees can be as high as 1% or even 2%.

The operation process of D委託 is actually not complicated. You place an order via your Taiwanese broker's app, which then转发 (forwards) it to the overseas partner broker. After the overseas broker executes the trade on the U.S. exchange, they report the results back to your Taiwanese broker, which finally updates your account. The stocks bought are held in the broker's overseas custody account, nominally owned by the broker, but you enjoy all rights, which is a common practice in international markets.

To open an account, you'll need to prepare dual ID documents, a seal, and a bank account copy, then apply at the broker's counter or directly online. When opening the account, tell the staff whether you want to settle in TWD or USD. After successfully opening the account, transfer funds into your D委託 account to start trading.

There are a few trading rules you must know. D委託 can only use limit orders; you cannot place market orders directly. If your account doesn't have enough funds, the order will fail to execute. U.S. stock trading hours are from 9:30 a.m. to 4:00 p.m. U.S. time, which is roughly 9:30 p.m. to 4:00 a.m. Taiwan time (an hour later during daylight saving time). After buying, settlement occurs on T+1; after selling, it takes T+3 days to settle. Another key point is that dividends from D委託 will involve a 30% income tax, but you can apply for a tax refund, though the process is somewhat complicated.

There are quite a few D委託 brokers in Taiwan, such as Fubon, Yuanta, Cathay, E.SUN, and KGI. Their fees are pretty similar, generally between 0.4% and 1%, but many brokers are willing to negotiate if your trading volume is large enough to get better discounts. I personally think, since you're already using D委託, just pick one with better service and more flexible fees.

If you trade very frequently or want access to more investment tools, you might consider opening an overseas broker account directly. The commissions are usually free, only paying exchange fees, which can significantly lower costs. Alternatively, you can try U.S. stock CFDs, which offer flexible leverage and low rates, suitable for those wanting more trading freedom.

Overall, D委託 is suitable for investors who don't trade very often, want to hold long-term, and prefer not to deal with complicated procedures. It's convenient, but you have to accept the higher transaction fees as a trade-off. If you're just starting to explore overseas investments, D委託 is indeed the easiest option.
