Seeing the heroes of capital also means seeing the price behind them.
In the second quarter, he was still heavily betting on optical communications; by the third quarter, he had made a major retreat. Zhang Jianping, known in the market as "Chief Zhang" and a top-tier super-retail investor, stumbled in the second quarter. Listed company third-quarter reports show that Zhang Jianping and his wife Fang Wenyan now together appear among the top ten circulating shareholders of 7 companies, with holdings worth more than 7 billion yuan. Zhang Jianping himself holds 3 stocks: Yunnan Germanium, Dongcai Technology, and Feilong Components. Fang Wenyan holds 4: Huazheng New Materials, Kexiang Co., Tianh Energy, and Founder Technology.
Compared with the second quarter, Zhang Jianping exited the top ten shareholder lists of ZJ INNOLIGHT (03308), Hengtong Optic-Electric, Hangdian Co., and Kexiang Co. Among them, Hengtong Optic-Electric was an optical fiber leader he had only built a position in during the first half of the year. At the end of June, he and Fang Wenyan had combined holdings worth as much as 6.154 billion yuan. On the other side, he moved against the trend into upstream plays. Yunnan Germanium was increased nearly threefold in a single quarter by him, with a period-end market value of 2.283 billion yuan. Dongcai Technology and Feilong Components were newly entered heavy positions.
In this portfolio adjustment, Zhang Jianping moved his chips from the midstream and downstream of optical communications to a position closer to the upstream of the industrial chain. Was he betting on new opportunities, or cutting losses in time?
Zhang Jianping's Capital Reshuffle
Zhang Jianping's withdrawal was concentrated in the midstream and downstream of optical communications and optical modules. Among these, the Hengtong Optic-Electric position deserves attention. In the 2026 semi-annual report, Zhang Jianping newly became the fifth-largest shareholder of Hengtong Optic-Electric, holding 34.4161 million shares; his wife Fang Wenyan newly became the eighth-largest shareholder, holding 21.8684 million shares. The combined reference market value of the two at period end was about 6.154 billion yuan. By the third-quarter report, however, both names had disappeared from Hengtong Optic-Electric's top ten shareholder list.
The same was true for Hangdian Co. Zhang Jianping newly became its third-largest shareholder in the second quarter, holding 24.3245 million shares, or 3.52%, with a period-end market value of 1.213 billion yuan. In the third-quarter report, the tenth-largest shareholder held only 2.5313 million shares, implying a reduction of nearly 90%. ZJ INNOLIGHT (03308), an optical module leader, also appeared in his end-of-June holdings, with 5.9348 million shares as the ninth-largest circulating shareholder. It was likewise absent from the third-quarter report.
So where did Zhang Jianping move his chips? The heaviest weight landed on Yunnan Germanium. Zhang Jianping's holdings jumped from 6.6598 million shares at the end of June to 26.2755 million shares, an increase of 294.54%, with a period-end market value of about 2.283 billion yuan, making him the third-largest shareholder. This is a substrate material supplier at the very upstream of the optical module industry chain. Its core product, indium phosphide chips, are key substrates for lasers and detector chips in optical modules. Interestingly, Yunnan Germanium's share price fell 27.71% cumulatively in the third quarter. Zhang Jianping added to his position against the decline, while the company's net profit in the first three quarters rose 869.79% year on year, and in the third quarter alone surged 2,642.24%, just as its performance entered an explosive phase.
Another position was Dongcai Technology. In the third quarter, Zhang Jianping newly became its third-largest circulating shareholder, holding 29.7473 million shares. The company's main focus is high-speed electronic resins, which are core materials for manufacturing high-end PCBs. In the first three quarters, Dongcai Technology's high-speed electronic resin business revenue was 883 million yuan, up 126.97% year on year.
Another company, Feilong Components, belongs to the thermal management track. He newly became its fourth-largest shareholder, holding 11.8109 million shares, betting on the penetration of liquid-cooled electronic pumps in server cooling scenarios.
Fang Wenyan's moves were more diversified, but broadly in the same direction. She newly became the second-largest shareholder of Huazheng New Materials, holding 7.7747 million shares, or 4.96%. The company focuses on copper-clad laminates, the direct raw material for PCBs. She newly became the seventh-largest shareholder of Founder Technology and the eighth-largest shareholder of Kexiang Co., both PCB manufacturers. She also newly became the fourth-largest shareholder of Tianh Energy, which involves key upstream materials for optical communications such as thin-film lithium niobate. As Zhang Jianping exited Kexiang Co., Fang Wenyan bought in to take over, widely seen by the market as a relay of chips within the family.
The performance of these targets is also being realized in tandem. Financial reports show that Huazheng New Materials' net profit in the first three quarters increased by more than 3,000% year on year. Founder Technology's first-three-quarter revenue was 6.128 billion yuan and net profit was 1.189 billion yuan, up 275.65% year on year. Kexiang Co.'s third-quarter revenue was 1.85 billion yuan, up 100.9% year on year, and net profit was 311 million yuan, turning profitable from a year-earlier loss.
Putting the couple's holdings together, the direction of the third-quarter adjustment becomes clear. From indium phosphide substrates, electronic resins, and copper-clad laminates to PCB manufacturers and then server cooling, the Zhang Jianping family spread its positions across the entire AI computing hardware industry chain, but retreated from the most crowded midstream to earlier upstream materials.
"Chief Zhang's" Losses
In the third quarter of 2026, the CSI 300 Index fell 12.49%, the ChiNext Index fell 27.80%, and the STAR 50 Index fell 30.70%, while the CSI Dividend Index rose 9.38% against the trend. The technology growth track suffered its most severe valuation compression of the year, with optical modules, memory chips, printed circuit boards, and other previously most crowded directions retreating especially sharply. Zhang Jianping's exits and entries occurred under exactly these conditions.
In the first quarter of 2026, Zhang Jianping exited the top ten circulating shareholders of Cambricon, reducing at least 4.79 million shares. But almost as he left, Cambricon surged more than 85% in the second quarter. Some market participants estimated that by "selling one step too early," he missed out on at least 4 billion yuan in gains.
In February this year, Zhang Jianping's wife Fang Wenyan participated in JAC Motors' private placement at 49.88 yuan per share, spending 1 billion yuan to subscribe to 20.0481 million shares, with a six-month lock-up period. At the time, the intelligent driving story was still in full swing. JAC Motors' intraday high for the year had reached 58.79 yuan per share, but by August 12, the day the placement was unlocked, JAC Motors closed at 25.5 yuan per share, nearly halved, leaving this position with a floating loss of about 500 million yuan. The third-quarter report showed that Fang Wenyan had significantly reduced her JAC Motors stake and exited the top ten shareholder list.
In the second quarter, Zhang Jianping had cleared out resource stocks such as Northern Rare Earth, Sichuan Gold, and Dongcai Technology, cashing out about 4.4 billion yuan, and turned to press a large amount of capital into AI optical module leader ZJ INNOLIGHT (03308). As of the end of June, he held 5.9348 million shares of ZJ INNOLIGHT (03308), with a market value of 7.537 billion yuan. But from its historical high of 1,415 yuan in June to its November 2 close of 550 yuan per share, ZJ INNOLIGHT (03308) had fallen sharply. On this stock alone, the paper loss exceeded 3 billion yuan.
There were also losses on Hengtong Optic-Electric and Hangdian Co. Some market participants calculated that together, these three core AI computing positions had a paper loss of more than 5.5 billion yuan.
These "missteps" shared several common features: large capital, high concentration, and decisive bets at high sentiment levels. The industry direction may not have been entirely wrong. The AI computing trend was real, and demand for optical communications was real. But the right direction met the wrong entry timing, and the large capital size further magnified exit difficulty. The result was a concentrated realization of paper numbers.
Despite stumbling into many pitfalls, "Chief Zhang" is still the person the market follows to see holdings. As long as his name appears on a company's top ten shareholder list, it often causes that stock to be labeled with a "super-retail halo."
Zhang Jianping's "Survival Rules"
Public information shows that Zhang Jianping was born in 1967 in Lin'an, Zhejiang, and is now 59 years old. He graduated from Tianjin University of Commerce and was assigned after graduation to Hangzhou Jiefang Road Department Store, engaging in sales and wholesale of home appliances. In 1992, Zhang Jianping returned to his hometown of Lin'an, Zhejiang, and made a living repairing photocopiers. Had an accidental opportunity not brought him into the stock market, he might have become an "appliance king" by fixing machines.
In 1996, Zhang Jianping entered the stock market with 50,000 yuan. By 1997, the funds in his account had grown to 200,000 yuan. Later, thanks to the 1999 "small bull market," Zhang Jianping's capital reached 5 million yuan, as if he had won the lottery. Around 2000, his capital grew even larger, a hundredfold increase from the original 50,000 yuan.
Perhaps the money came too fast. Somewhat "inflated," Zhang Jianping rushed into the newly launched Hong Kong Growth Enterprise Market, only to lose half in six months. Having "learned from a fall," he traded more cautiously from then on, mainly using a "quick in, quick out" approach. He later made his name through Beijing North Star and China Merchants Energy Shipping, creating a "legend" of more than 100 million yuan in profits. Then, in Aluminum Corporation of China, he deployed capital on the scale of a billion yuan. In April 2007, Aluminum Corporation of China landed in the A-share market through a share swap merger. Zhang Jianping entered, and by October of that year the stock had risen to 60.6 yuan, ten times the issue price. The market estimated that he made at least 100 million yuan in that battle.
Since then, a "legend" has circulated in capital circles: in 2007, Zhang Jianping's personal assets were nearly 2 billion yuan, his stock trading volume in the Shanghai and Shenzhen markets had reached 70 billion yuan, and he paid 200 million yuan in stamp duty alone in one year. However, whether myth or legend, none of it has been confirmed by Zhang Jianping himself. But in 2008, after heavily betting on CITIC Securities and China Unicom and repeatedly suffering institutional selling, several large trades resulted in huge losses. Combined with regulatory window guidance and account restrictions, successive heavy blows left him silent and reflective for a long time.
It was also after this major loss that Zhang Jianping gradually shed the ferocity of a daredevil team player, moved toward trends, emphasized cycles, and studied mainline prosperity, evolving from a short-term limit-up trader into a large-capital trend player who "looks long and trades short." This playbook continues today. His frequently used seats at Guotai Junan Shanghai Jiangsu Road, Shanghai Haiyang West Road, and CITIC Hangzhou Siji Road remain among the most recognizable "Chief Zhang seats" on the dragon-tiger list. Yet he is exceptionally low-profile and rarely accepts media interviews. Family accounts operate like a combination punch. His wife Fang Wenyan, father-in-law Fang Deji, and son Fang ZhangLe often appear together in shareholder lists as persons acting in concert.
On August 16, 2024, Zhang Jianping was fined 500,000 yuan by the CSRC for borrowing another person's securities account to conduct securities trading. The person who lent the account was none other than his father-in-law Fang Deji, who was also fined 500,000 yuan. This incident led regulators to call out the "Zhang family team's" account linkage model.
What truly made a new generation of stock investors remember "Chief Zhang" was the battle in Cambricon in 2025. Market estimates put his four-month floating profit on Cambricon at about 5.6 billion yuan, taking the strategy of "heavily betting on the leading stock of the market's mainline" to the extreme. Some market analysis said he earned "the market's money," not "the company's money," by finding the resonance point among industry prosperity, market sentiment, and stock price elasticity, entering when resonance was strongest and exiting when resonance began to fade.
But super-retail holdings data are point-in-time figures at quarter end, with a lag of one to three months. Taking Hengtong Optic-Electric as an example, the current share price has already fallen substantially from the end of June, and Chief Zhang himself may well have reduced or even fully exited. Regarding the phenomenon of retail investors enthusiastically "copying homework," institutional figures generally warn of risks. Chen Xingwen, chief strategy officer of Heiqi Capital, once told the media that ordinary investors have a low win rate when "copying homework." The core misunderstanding is "seeing holdings but not position size; seeing results but not the process; seeing heroes but not the price." You cannot replicate super-retail investors' risk tolerance and information circles, let alone the multidimensional cognition they build through private placements, primary markets, and industry chain research.
Chen Xingwen believes that the correct reference method is absolutely not to copy a single stock, but to learn their "cognitive framework": understanding the quadrant of the industry cycle, the coordinate system for valuation anchoring, and the discipline of capital management. "See the results, but also see the process; see the heroes of capital, but also see the price." For ordinary investors, the top ten circulating shareholder list can only show the past traces of major players' buying and selling. Super-retail investors can withstand hundred-million-yuan-level trial and error, while retail investors can hardly replicate their information channels and capital scale. Rather than staring at the list and copying homework, it is better to understand the industrial logic behind it.
