What Trading Fees Should You Pay Attention to When Holding U.S. Stocks Long Term?

When holding U.S. stocks long term, the most important costs are not the repeated costs generated by frequent trading, but the total fees across the full cycle of “buy once, hold for years, eventually sell, and move funds in or out.” When buying, you need to check commissions, platform fees, bid-ask spreads, and currency conversion costs. During the holding period, you need to watch ETF expense ratios, ADR depositary fees, account maintenance fees, or funding-related charges. When selling, you also need to consider SEC Fee, FINRA TAF, settlement fees, and platform rules. To judge long-term cost, do not only look at a single commission item; look at the net return across the full holding cycle.

Key Takeaways

• Long-term U.S. stock investors should consider buying, holding, selling, and funding costs.
• With low trading frequency, single platform fees may matter less, but minimum fees still need checking.
• Long-term ETF holders should focus on expense ratios and fund-level costs.
• ADR stocks may involve depositary fees that do not necessarily appear on buy or sell dates.
• Selling may still involve SEC Fee and FINRA TAF.
• Long-term cost should be judged by the full cycle, not by a single order.

How Are Fee Priorities Different for Long-Term U.S. Stock Holding and Short-Term Trading?

When holding U.S. stocks long term, fee priorities are different from short-term trading. Short-term trading is more affected by repeated platform fees, spreads, and external fees. Long-term holding is more about entry cost, holding-period costs, eventual selling costs, and funding-path costs. You do not need to check fees every day, but you should confirm costs before buying, during the holding period, and before selling.

Long-term holding does not mean there are no fees; it means fees occur less frequently. When buying, you may pay commission, platform fees, bid-ask spread costs, and currency conversion costs once. During the holding period, you may continue to bear ETF annual fees, ADR fees, account maintenance fees, or funding service fees. When selling, you may face SEC Fee, FINRA TAF, platform fees, settlement fees, and currency conversion or withdrawal costs. The SEC’s Understanding Fees reminds investors that even fees that seem small can affect portfolio value over time, which is especially important for long-term investors.

Long-term costs depend more on “time” and “product type.” The same US$1 fee affects a day trader and a five-year holder differently. Similarly, ordinary stocks, ETFs, ADRs, REITs, and leveraged ETFs all have different fee structures. Ordinary stocks usually do not have fund annual fees. ETFs require attention to expense ratios. ADRs may involve depositary fees. REITs may also involve more complex dividend and tax treatment.

A common mistake among long-term investors is checking the trading fee only on the purchase date and then ignoring costs for years. In reality, fees may not appear on the same day. ETF expenses are reflected in NAV. ADR fees may be deducted during the holding period. Account fees may appear monthly, quarterly, or annually. Sell-side regulatory fees only appear when exiting. They may not remind you every day, but together they affect long-term net returns.

Summary: Holding U.S. stocks long term does not mean trading fees can be ignored. Instead, fees should be viewed across the full investment cycle. Short-term trading focuses on frequency; long-term holding focuses on time. A single buy or sell cost may not be high, but ETF annual fees, ADR fees, account fees, currency conversion costs, and final sell-side regulatory fees can jointly affect long-term net returns. When judging long-term costs, the most important point is not whether commission is zero, but the complete chain from funding the account, buying and holding, eventually selling, and withdrawing funds.

What One-Time Fees Should Long-Term Investors Check When Buying U.S. Stocks?

The first type of cost for long-term U.S. stock investors is the one-time cost incurred when buying. You need to check commissions, platform fees, minimum fees per order, bid-ask spreads, currency conversion costs, and deposit costs. Long-term investors trade less frequently, but if the entry amount is small, purchases are split into many batches, or funding involves currency conversion, buying-stage fees can still affect the actual cost basis.

Commissions and Platform Fees: Long-Term Investors Should Not Only Look at “Zero Commission”

Zero commission only means the commission field is zero. It does not mean platform fees, order service fees, external institution fees, settlement fees, and regulatory-related fees are all zero. FINRA’s Fees and Commissions explains that buying and selling stocks, bonds, and other investment products usually involves different forms of costs, and fees may vary by account type, service, and product.

Although long-term investors trade less frequently, entry costs still become part of the holding cost. If you buy a larger amount in one order, the platform fee as a percentage of the order value may be lower. If you make many small purchases, minimum fees may appear repeatedly. Long-term holding does not mean order fees can be ignored; it means the entry plan should be considered in advance.

Bid-Ask Spread: An Easily Overlooked Entry Cost

The bid-ask spread is not a fee listed separately on a statement, but it is a real cost. When buying, you usually trade at or near the seller’s quoted price. If the security is not liquid, the difference between the best ask and best bid can be wide. Long-term investors trade less often, but if they buy illiquid stocks, small-cap stocks, or trade during pre-market or after-hours sessions, spreads can still affect entry price.

Market orders and limit orders also affect cost. Market orders prioritize execution speed, but may be filled at an unfavorable price during volatile periods. Limit orders help control price, but do not guarantee execution. Long-term investors usually do not need to chase the fastest execution; they should focus more on building positions at reasonable prices.

Currency Conversion and Deposit Costs: Important for Cross-Currency Investing

International market users may need to convert local currency into U.S. dollars and transfer funds before buying U.S. stocks. Exchange-rate spreads, FX fees, bank charges, or payment channel fees may not appear on the U.S. stock trade confirmation, but they affect the actual amount available for investment. If you use non-USD funds to allocate to U.S. stocks long term, funding-path costs should also be included in initial cost.

Summary: Buying-stage fees are usually not recurring high-frequency costs for long-term investors, but they directly determine the initial cost basis. Commissions, platform fees, minimum fees, bid-ask spreads, currency conversion costs, and deposit costs should all be checked before building a position. Costs may be higher than expected when making small batch purchases, buying illiquid stocks, funding across currencies, or using market orders. The first step in long-term holding is to confirm that entry costs are transparent, acceptable, and not magnified by overly small batches or a complex funding path.

Which Holding-Period Fees Are Most Easily Overlooked by Long-Term Investors?

The most easily overlooked fees in long-term U.S. stock investing are often not the transaction fees shown on the buy or sell date, but costs that occur continuously or intermittently during the holding period. ETFs have expense ratios, ADRs may involve depositary service fees, and some platforms may charge account, custody, data, or funding-related fees. These costs may not appear each time you trade, but they affect long-term net returns.

ETF Expense Ratio: The Core Cost of Holding ETFs Long Term

If you hold U.S. stock ETFs long term, the expense ratio is one of the most important costs. The SEC’s investor materials on Mutual Fund and ETF Fees and Expenses state that fund prospectuses must disclose a standardized fee table, with fees mainly including annual operating expenses and shareholder fees.

An ETF expense ratio is usually not deducted separately on the trade date like a commission. Instead, it is reflected in the fund’s net asset value. You may not see an “ETF annual fee deduction” in your account, but the fund’s long-term performance already includes this cost. Broad-market index ETFs usually have lower fees, while actively managed ETFs, thematic ETFs, leveraged ETFs, and complex strategy ETFs may have higher fees.

The SEC’s explanation of Exchange-Traded Funds also reminds investors that ETF fees and expenses vary by fund, and even small fee differences may lead to meaningful return differences over the long term.

ADR Fee: Not a Trading Fee, but It May Affect Holding Cost

If you hold ADR stocks long term, you need to pay attention to depositary fees. The SEC’s explanation of American Depositary Receipts states that ADRs represent shares of foreign companies in the U.S. market. They trade in the U.S., but involve a depositary bank and underlying foreign shares.

The SEC’s ADR investor bulletin notes that ADR fees are usually charged based on the number of ADRs and gives an example where 1,000 ADRs may generate fees in the range of US$20 to US$50. Whether the fee is charged, when it is charged, and how much it is should be checked against the ADR deposit agreement, platform statement, and related disclosures.

Account Maintenance, Data, and Funding-Related Fees

Long-term investors trade less, but account-related fees may still exist. Some platforms may charge account maintenance fees, real-time market data fees, custody fees, fund transfer fees, deposit and withdrawal fees, or idle-fund-related charges. These fees may not be tied to a specific trade, but may appear in monthly or quarterly statements.

Summary: The costs long-term investors most easily overlook are not the clearly displayed trading fees on the order date, but the costs that occur continuously or intermittently during the holding period. ETF expense ratios are reflected in fund NAV over time. ADR fees may appear while holding. Account maintenance, data subscriptions, custody services, and funding-related fees can also affect long-term net returns. When holding U.S. stocks long term, investors should regularly review account statements and product documents, not only check fees on the purchase date. This is especially important when holding ETFs, ADRs, or cross-currency accounts.

What Exit Costs Should You Watch When Selling After Long-Term Holding?

When you eventually sell U.S. stocks after holding them long term, exit costs can also arise. In addition to platform fees and bid-ask spreads, sell orders may involve SEC Fee, FINRA TAF, CAT Fee, settlement fees, or clearing fees. Because long-term investors sell less frequently but may sell larger amounts at once, you should check transaction value, share count, regulatory fees, fund settlement, and FX impact before selling.

SEC Fee: Focus on Transaction Value When Selling Long-Term Holdings

The U.S. SEC’s Section 31 fee rate applies to covered sales, and starting April 4, 2026, the rate is US$20.60 per US$1 million in transaction value. For long-term investors, this type of fee usually appears only when selling, but if the sale amount is large, its calculation basis should be understood in advance.

FINRA TAF: Focus on Share Count When Selling Long-Term Holdings

FINRA’s Member Regulatory Fees page lists the Trading Activity Fee for covered equity securities as US$0.000166 per share, capped at US$8.30 per trade. FINRA’s explanation of the Trading Activity Fee also states that ETFs and other structured products are generally subject to TAF, while transfers of underlying securities in ETF creations and redemptions are not subject to TAF.

For long-term investors, the key variable for TAF is the number of shares sold. High-priced stocks may involve fewer shares, while low-priced stocks, accumulated fractional shares, or dividend reinvestment positions may involve more shares. If you sell in batches, you should also consider per-trade caps and how the platform displays the fee.

Tax and Funding Treatment Should Not Be Mixed with Trading Fees

International investors holding U.S. stocks long term may also face dividend withholding tax, tax treaty considerations, currency conversion, and withdrawal costs. The IRS explanation of withholding on specific income states that U.S.-source income that is not effectively connected with a U.S. trade or business may be subject to NRA withholding. The IRS discussion of taxation of nonresident aliens also notes that FDAP income is generally subject to a 30% tax rate, or a lower treaty rate when applicable.

Taxes are not the same as trading fees and should not be simply attributed to platform charges. But they affect net returns after long-term holding, so they should be recorded and evaluated separately. Withdrawal and currency conversion costs are similar: they are not stock-trading fees in the strict sense, but they affect the final amount received.

Summary: When selling after long-term holding, you should not only look at the sale price; you should also check exit costs. SEC Fee is usually understood based on sell transaction value, while FINRA TAF is usually based on shares sold. Platform fees, CAT Fee, settlement fees, and bid-ask spreads may also affect the final amount received. Long-term investors sell less often, but a single sale may be large, so estimated fees and executed statements should be reviewed before selling. Taxes and withdrawal costs are not exactly trading fees, but they affect final net returns and should be recorded and evaluated separately.

How Should Fee Priorities Differ Across U.S. Stock Products Held Long Term?

When holding U.S. stock products long term, fee priorities differ by product type. Ordinary U.S. stocks mainly require attention to buy/sell fees, platform fees, and liquidity. ETFs require additional attention to expense ratios, premiums/discounts, and tracking error. ADRs may involve depositary fees. REITs require attention to dividends and tax treatment. Fractional shares and low-priced stocks require attention to platform fees, minimum fees, and per-share costs.

Ordinary stocks have relatively direct fee structures. They have no ETF expense ratio and no index-tracking error. The main costs are buy/sell fees, platform fees, spreads, and sell-side regulatory fees. Highly liquid large-cap stocks usually have lower trading friction, while small-cap, low-priced, and less popular stocks may have wider spreads and higher execution costs.

ETFs “trade like stocks but are held like funds.” When you buy or sell ETFs, trading fees are similar to stocks. During the holding period, you also need to look at expense ratios, fund size, tracking error, premiums/discounts, and underlying asset liquidity. Thematic ETFs, actively managed ETFs, leveraged ETFs, and complex strategy ETFs especially require careful review of fees and risks.

ADRs, REITs, fractional shares, and low-priced stocks each require separate checks. ADRs require attention to depositary fees and dividend handling. REITs require attention to dividends, taxes, and product rules. Fractional shares require checking whether the platform has separate fee rules. Low-priced stocks require attention to per-share fees, FINRA TAF, and bid-ask spreads. The more special the product, the less you should rely only on the commission field.

If you plan to hold U.S. stocks long term, you should pay attention not only to fundamentals, but also to actual trading costs. U.S. stock trading costs usually include more than commissions. They may also include platform fees, external institution fees, trading activity fees, settlement fees, ETF holding costs, ADR depositary fees, currency conversion, and deposit/withdrawal costs. Long-term investors trade less often, but hold for longer, so they should break down costs by product type rather than treating all U.S. stocks under one cost framework.

Summary: Long-term U.S. stock investing should not treat all products simply as “stocks” for fee analysis. Ordinary stocks have relatively simple fee structures, but concentrated risk. ETFs add fund-level expense ratios and tracking costs. ADRs may involve depositary fees. REITs, low-priced stocks, and fractional shares also have their own fee and tax considerations. When judging long-term holding costs, first identify the product type, then check the source of each fee. The more complex the product, the less you should rely only on the commission field on the order page; product documents, account statements, and platform fee schedules should all be reviewed.

How to Build a Fee-Checking Framework for Long-Term U.S. Stock Holding

A fee-checking framework for long-term U.S. stock holding can follow four steps: before building a position, during the holding period, before selling, and after withdrawing funds. Before buying, check platform fees, bid-ask spreads, and currency conversion costs. During holding, check ETF, ADR, and account-related fees. Before selling, estimate SEC Fee, FINRA TAF, and exit costs. After withdrawing funds, verify the actual amount received.

Before building a position, confirm the trading and funding path. You need to know whether there are commissions and platform fees, whether a minimum fee per order applies, whether deposits and currency conversion add costs, and whether the security is an ordinary stock, ETF, or ADR. During the holding period, review account statements regularly. FINRA’s guidance on brokerage account statements emphasizes that investors should compare fee disclosures with actual charges in their accounts and ask questions about unclear fees.

Before selling, estimate exit costs again. You need to consider sell transaction value, number of shares sold, platform fees, external fees, spreads, and withdrawal path. If the security is illiquid, selling in batches may reduce market impact, but it may also increase the number of orders. If cross-currency withdrawal is involved, you should also check the actual amount received.

Before holding U.S. stocks long term, check these eight questions:

• Does buying involve commission or platform fee?
• Is there a minimum fee per order?
• What are the deposit and currency conversion costs?
• Is the security an ordinary stock, ETF, or ADR?
• Does the ETF have an expense ratio?
• Could the ADR involve depositary fees?
• Will selling involve SEC Fee and FINRA TAF?
• Will final fund withdrawal involve extra costs?

If you want to check costs more clearly before holding U.S. stocks long term, Biya supports U.S. stocks, Hong Kong stocks, and crypto trading, and also supports conversion of USDT into major fiat currencies such as USD or HKD. For long-term holding scenarios, you can first review U.S. stock trading fees, then check platform fees, external institution fees, and fractional share rules on the actual order page.

Biya charges US$0 commission for U.S. stock trading. Its platform fee is US$0.005 per share, with a minimum of US$0.99 per order and a maximum of 1% of transaction value. External institution fees and trading activity fees total US$0.00396 per share. The fee schedule also states that fractional share orders with executed quantity below 1 share are charged only a platform fee of 1% of total transaction amount, capped at US$1. Platform fees, external institution fees, and other charges are subject to the fee schedule and order page display.

When researching long-term securities, you can also use the U.S. stock search tool to check security information first, then use the Biya App to verify account support, order fee display, and trading access. Service availability depends on the user’s location, identity verification results, platform rules, and applicable laws and regulations. The above content only introduces public market information, trading rules, and fee structures, and does not constitute investment advice.

Summary: Fee checks for long-term U.S. stock holding should not stop at the order placement stage. A more complete approach is to confirm platform fees, minimum fees, and the funding path before building a position; check ETF, ADR, and account-related fees during the holding period; estimate regulatory fees and exit costs before selling; and confirm the actual amount received after withdrawing funds. By breaking costs down across the full lifecycle, long-term investors can judge real costs more clearly instead of relying only on “zero commission” or a single order display.

FAQ

Do Long-Term U.S. Stock Investors Still Need to Pay Attention to Trading Fees?

Yes. Although long-term U.S. stock investors trade less frequently, buy-side platform fees, sell-side regulatory fees, ETF annual expenses, ADR depositary fees, currency conversion, and deposit/withdrawal costs can still affect net returns. Fees should be checked across the full holding cycle.

What Is the Most Important Fee for Long-Term U.S. Stock ETF Holders?

For long-term U.S. stock ETF holders, the most important fee is usually the expense ratio. It is not a trading fee deducted separately when placing an order, but an annual operating cost reflected in the fund’s NAV. Premiums/discounts, tracking error, and bid-ask spreads should also be considered.

Do Ordinary U.S. Stocks Have Annual Fees When Held Long Term?

Ordinary U.S. stocks usually do not have fund annual fees such as ETF expense ratios, but platform fees, account service fees, sell-side regulatory fees, or funding-related costs may still exist. If the stock is an ADR, depositary fees may also apply.

What Fees May Apply When Selling U.S. Stocks After Long-Term Holding?

When selling U.S. stocks after long-term holding, possible costs include platform fees, SEC Fee, FINRA TAF, CAT Fee, settlement fees, and bid-ask spreads. SEC Fee is usually understood based on sell transaction value, while FINRA TAF is usually based on shares sold.

Why Might Long-Term U.S. Stock ADR Holdings Incur Fees?

Long-term U.S. stock ADR holdings may incur depositary service fees because ADRs are issued and maintained by depositary banks. Fees may be charged based on the number of ADRs, or may appear during dividends or on specific billing dates. Actual charges should be checked against the deposit agreement and platform statement.

How Can You Tell Whether the Total Cost of Long-Term U.S. Stock Holding Is Reasonable?

To judge whether the total cost of long-term U.S. stock holding is reasonable, combine buying costs, holding-period fees, selling costs, currency conversion, and funding costs. Then compare total fees with holding amount, holding period, and net return, instead of looking only at a single commission item.
