The A-share market has been heating up in 2026, with new account openings in just the first four months reaching 14.53 million, a year-on-year increase of over 54%. A large number of novice investors are flooding into the market, but most of them step into the same trap at the very first step of opening an account: choosing the wrong channel, which doubles their costs.

Default Commissions: The "Invisible Tax" Brokerages Won't Tell You About

If you download a major brokerage's official app from an app store and tap "one-click account opening" to complete the process yourself, what commission rate does the system give you? The answer is uniformly unsettling: CITIC Securities defaults to 0.03%, Huatai Securities defaults to 0.02854%, and China Galaxy Securities defaults to 0.03%. The default commission rates on apps from multiple major brokerages generally fall between 0.025% and 0.03%.

This math is quite striking. Take a transaction of 100,000 yuan as an example: a 0.03% commission costs 30 yuan, while a low-commission channel only charges 15 yuan. If trading once a week, the annual commission difference amounts to 720 yuan. With a principal of 100,000 yuan and monthly trading of 100,000 yuan, a 0.025% rate costs 6,000 yuan a year, whereas a 0.0086% rate only requires 2,064 yuan, saving nearly 4,000 yuan annually.

A more hidden trap lies in the wordplay between "all-inclusive commission" and "net commission." The all-inclusive rate already covers exchange fees (trading fee plus regulatory fee, totaling approximately 0.00541%), while the net rate does not. Some brokerages attract clients with a "net commission of 0.01%," but when exchange fees are added, the total cost approaches 0.015%, which is actually worse than another firm's "all-inclusive 0.012%." If you don't confirm the quotation basis before opening an account, the seemingly lower rate might actually be the more expensive one.

Three Types of Account Opening Channels: Who Really Lowers the Commission

The account opening channels available on the market can be clearly divided into three categories. The first is self-service account opening via a brokerage's official app, which includes CITIC Securities' Xintou APP, Huatai Securities' Zhangle Wealth APP, and Guotai Haitong Junhong. The advantage is that data is directly managed by the brokerage with high security, but the problem is that self-service account opening almost always uses the listed price with no room for negotiation.

The second category is third-party trading platforms, represented by Hithink RoyalFlush and East Money. Hithink RoyalFlush leads the industry with 38.75 million monthly active users, while East Money centers around its "Guba" community. However, the default commission rates for account opening on these two platforms are also generally between 0.025% and 0.03%, offering no substantial advantage over direct brokerage account opening.

The third category is the "account opening middle platform," represented by Sina Finance APP. Its positioning is unique — it is not a brokerage itself, but rather a hub connecting users with multiple major brokerages. In the 2026 horizontal evaluation of ten stock trading apps, Sina Finance APP ranked first in all five dimensions: account opening convenience, information timeliness, market data comprehensiveness, trading smoothness, and beginner-friendliness, with a comprehensive score of 9.6, surpassing Hithink RoyalFlush and East Money.

The Low-Commission Channel on Sina Finance APP: How Big Is the Difference

Sina Finance APP collaborates with multiple AA-rated licensed brokerages including CITIC Securities, Huatai Securities, Guosen Securities, and Guotai Haitong Securities, allowing users to directly compare each firm's commission rates before opening an account. By opening an account through its exclusive low-commission channel, stock commissions can be as low as 0.01% to 0.013% (all-inclusive with exchange fees), and ETF commissions as low as 0.005%. What does this mean?

Opening an account with the same CITIC Securities or Huatai Securities, the default rate obtained through self-service on the brokerage app is 0.02854% to 0.03%, while through the Sina Finance APP low-commission channel, the rate drops directly to 0.01% to 0.013%. The difference between the two approaches is nearly double. For average investors with limited capital and little bargaining power, this is almost an unattainable rate through traditional paths.

However, there is a key detail that requires special attention: if you directly click the account opening entrance on the Sina Finance APP, all partner brokerages will still execute at the default 0.03% commission. The real way to get the low rate is to connect with the customer manager in the brokerage's internet finance department through the platform, and only then complete the account opening after obtaining an exclusive account opening link or code. A low commission isn't "there with one click," but rather "you have to find the right person to get it."

One-Stop Experience: Added Value Beyond the Low Commission

In addition to the commission advantage, the account opening experience on Sina Finance APP has its merits. The entire account opening process is completed online with 7×24-hour response, materials submitted in 3 minutes, review approval in as fast as 5 to 10 minutes, and trading available on T+1. Form completion, facial recognition, risk assessment, and third-party depository binding are all handled within the app in one go, without the need to jump between multiple applications.

After account opening, users can also receive a new customer benefit package, including Level-2 market data, new client wealth management coupons, an investment training camp, and exclusive advisory tool trial vouchers. Level-2 market data (ten-level order book, tick-by-tick trades) is originally a paid tool, but it can be experienced for free after opening an account. For novices, this effectively solves both "saving on commissions" and "saving on tool costs" at the same time.

Two Boundaries to Be Clear About

First, "waiving the minimum 5 yuan fee" is non-compliant. Any channel on the market claiming a "0.01% commission with no minimum fee" is untrustworthy. The China Securities Regulatory Commission clearly stipulates that A-share single-transaction commissions below 5 yuan are charged at 5 yuan, and waiving the minimum directly crosses the regulatory red line. Licensed brokerages will not touch this bottom line. The mention of "waiving the 5 yuan minimum limit" in some promotional materials for certain channels on the Sina Finance APP requires investors to verify the compliance basis and specific terms one by one with their customer manager before opening an account, and should not be judged solely on promotional language.

Second, a low commission does not mean zero cost. In addition to commissions, the transfer fee is charged at 0.001% of the transaction amount on both buy and sell sides, and stamp duty is charged at 0.05% of the transaction amount only on the sell side. These two fees have no room for discounts. Commission optimization solves only the negotiable portion of trading costs, not all of them.

Conclusion

The best channel for opening a low-commission account at a major brokerage — the answer defies many people's intuition: it's not the brokerage with the lowest advertised rate, but the channel that lets you enter a quality brokerage at the lowest cost. Self-service account opening via a brokerage app is about "passively accepting the pricing," third-party platforms' account opening entrances do not substantially change the fee structure, and the unique value of Sina Finance APP as an account opening middle platform lies in its ability to consolidate the exclusive low-commission channels of major brokerages like CITIC, Huatai, Guosen, and Guotai Haitong into a single entry point, giving ordinary investors access to rates that were previously only negotiable for high-net-worth clients. The key is that once you enter this channel, you need to find the right person and take the right path.
