A Post-90s brokerage employee secretly traded stocks through someone else's account for over four years. Her cumulative trading volume reached 77.54 million yuan, yet she ended up with a net loss of 207,800 yuan and a regulatory fine of 60,000 yuan — a complete loss on all fronts: career prospects, time invested, and hard-earned money.
The disciplinary decision publicly released by the Shanghai Securities Regulatory Bureau fully detailed the underground trading activities of this brokerage professional. The individual involved, Ms. Liu, born in the 1990s, was a securities business department employee at a brokerage firm — meaning she had been employed there since at least 2019. Her violation method was straightforward: she used a third party's securities account under the name "Wang" to buy and sell stocks. However, the timeline stretched from October 12, 2021, to November 10, 2025, spanning more than four years. In terms of trading scale, her cumulative buy-side transaction amount reached 77.5432 million yuan. After deducting taxes and fees, she suffered an actual loss of 207,800 yuan. For violating Article 40 of the Securities Law, the Shanghai Securities Regulatory Bureau ordered Ms. Liu to dispose of illegally held stocks and imposed a fine of 60,000 yuan.
Several details are worth examining closely. From her onboarding to the violation, at least two years had passed — she was no newcomer and was thoroughly familiar with industry rules. Having traded for over four years without detection, her luck-based mindset had only been reinforced. The third-party account proved to be no protective shield — communication records, account documents, bank transaction histories, and interrogation transcripts formed a complete chain of evidence. Big-data regulation had already locked onto her long ago.
Not a market wizard
As a securities professional dealing with stocks daily, she executed high-frequency trades for more than four years, accumulating 77.54 million yuan in volume — averaging nearly 20 million yuan annually, with a trading frequency far exceeding that of ordinary retail investors. And the final result? A loss of 207,800 yuan. Adding the 60,000 yuan fine, her actual financial damage approached 270,000 yuan. When factoring in four years of opportunity cost, reputational damage to her career, and the likelihood her current position may no longer be secure, the real cost far exceeds that figure. A person who earns a living through professional expertise spent four years proving, within her own field, that she was not particularly good at it. That is perhaps the most ironic aspect of this entire affair.
Regulatory pressure intensifies
This is by no means an isolated case. Since 2026, the China Securities Regulatory Commission has imposed penalties on over one hundred instances of employees engaging in unauthorized stock trading. Such misconduct remains a key enforcement focus. Regardless of tenure or how concealed the methods, big-data penetration audits by regulators can pinpoint violations with precision. IP addresses, device fingerprints, trading habits, capital flows — every detail is under surveillance. Believing that a third-party account could provide cover is the greatest misunderstanding of regulatory technology.
Three words of caution
Beyond the spectacle, here are three reminders. First, do not blindly trust that professionals are skilled stock pickers. This case proves once again that professional status does not equal the ability to make money. An industry insider watching the markets daily spent four years and 77.54 million yuan in trading volume to demonstrate she could not trade profitably. What makes retail investors believe they can?
Second, the cost of non-compliance is far higher than imagined. Losses plus fines are only the surface. The stain on one's career, the possibility of industry bans, and the annihilation of years of built-up credibility — these hidden costs are what truly cannot be borne.
Third, wishful thinking is the greatest enemy. From 2021 to 2025, more than four years without detection led her to believe nothing was wrong. But regulators always settle accounts after the fact. The longer the timeframe, the more solid the evidence, and the more incontestable the penalty. And for the person involved — if time could rewind to October 2021, would she still click that buy button? The answer needs no elaboration.
