Zhongji Innolight fell 9.19% on November 6. Between the number of shareholders as of September 30 and the margin financing balance after market close on November 6, which one can prove that the funds that withdrew were leveraged funds rather than institutional funds?

Zhongji Innolight fell 9.19% on November 6. Between the number of shareholders as of September 30 and the margin financing balance after market close on November 6, which one can prove that the funds that withdrew were leveraged funds rather than institutional funds?

Strictly speaking, neither of the two proves "what was withdrawn was leveraged capital rather than institutions." To take a step back, the margin financing balance is the only thing even tangentially related; the number of shareholders not only fails to help, but points in the opposite direction—in the third quarter the number of holders rose from 20.57 wan to 23.71 wan, and Hong Kong Central Clearing reduced its holdings by 988 wan shares, which is a sign of chips flowing from institutions to accounts, not "only leverage is withdrawing."

The two data sets are not on the same clock

The number of shareholders follows a quarterly process: ChinaClear produces figures based on the register of names at quarter-end, the listed company fills them into the quarterly report, and they land in the 2026 third-quarter report "Section 2 Shareholder Information," in the cell "total number of ordinary shareholders at the end of the reporting period," frozen at 237,107 holders on September 30. The next cell is December 31, which will not be visible until April 2027.

The margin financing balance follows a daily process: brokers report client credit account details to the Shenzhen Stock Exchange every day, the exchange aggregates them into the daily margin trading report, and after the close on November 6 it was 166.44 yi yuan. It does not enter the income statement, nor the balance sheet, and has no quarterly attribution.

One cell per quarter, one cell per day. Between September 30 and November 6 there were 22 trading days, the stock price fell from 808.44 yuan to 448.00 yuan, and the shareholder-count line is blank. Using a quarterly photograph to explain a single-day move erases all the changes over those 22 days.

The shareholder-count table itself also does not support "institutions did not leave." In the third quarter the count was +15.28% quarter-on-quarter, the second consecutive quarter of expansion; over the same period northbound holdings fell from 7,332.66 wan shares to 6,344.45 wan shares, a decrease of 988 wan shares.

CITIC Securities proprietary trading with 547.5 wan shares, Guotai CSI All Share Communications Equipment ETF with 678.9 wan shares, and Zhang Jianping with 593.5 wan shares, all still in the top ten in the second quarter, all dropped out of the top ten in the third quarter; China Life traditional insurance account with 759.8 wan shares came in. The threshold for tenth place in the third-quarter report is exactly 759.8 wan shares; dropping out only means the holding was reduced below the threshold, which does not equal a full liquidation.

There is another layer: "holder" does not equal "retail investor." Based on total share capital of 11.78 yi shares and 23.71 wan holders, average holdings per holder are 4,967 shares, and at the November 6 closing price of 448 yuan the average market value per holder is 222 wan yuan. The register mixes institutional accounts, credit accounts, and large holders; using headcount to infer "retail investors are catching the falling knife" is not solid.

What the margin financing balance can prove is only one sentence

On November 6, margin financing purchases were 20.09 yi yuan, margin financing repayments were 35.10 yi yuan, net repayment was 15.02 yi yuan, and the balance fell from 181.45 yi yuan to 166.44 yi yuan. These are hard numbers that can be verified day by day.

Put against the tape, the magnitude is wrong: that day's turnover was 239.73 yi yuan, margin purchases accounted for only 8.4%, and net repayment only 6.3%. Even if all 15.02 yi yuan were selling pressure, it could not explain -9.19%.

Looking over a longer stretch makes it clearer. From October 22 to November 6 the balance net decreased by 72.85 yi yuan; over these 11 trading days cumulative turnover was 2,562 yi yuan, and net repayment accounted for 2.8%. Leveraged positions are withdrawing, and not slowly, but the withdrawal took a full two weeks, not just November 6.

One point easily overlooked: the third-quarter report's "explanation of the situation of the top 10 shareholders participating in margin financing and securities lending" states that the controlling shareholder Shandong Zhongji Investment Holding, in addition to holding 9,194.81 wan shares through an ordinary account, also holds 2,949.20 wan shares through a client credit trading collateral securities account; Suzhou Furui Hui has another 200 wan shares in a credit account.

The "margin financing positions" mix in collateral accounts of industrial capital, which are not all retail leverage; treating them wholesale as "leveraged capital" means the premise is already impure.

On the same day, all four were deleveraging

The highest margin financing balance as a share of circulating market value is Eoptolink at 4.81%, down 7.28%; Zhongji Innolight at 3.35%, almost the same as TFC at 3.34% and Accelink at 3.34%, yet it fell the hardest. Leverage intensity cannot explain the difference in declines.

Over the 11 days the four companies' balances decreased by 30.4%, 29.7%, 27.1%, and 23.6% respectively, almost in sync—the entire optical module chain is deleveraging, not one institution selling off.

The only difference lies with Zhongji Innolight itself: its margin financing balance as a share of circulating market value fell from 3.65% to 3.35%, the only one of the four to decline, while the shares of Eoptolink, TFC, and Accelink actually rose. It withdrew slightly more than the sector, but the excess absolute amount is about 15 yi yuan, roughly the net repayment of a single day on November 6.

What is missing is exactly the evidence that can distinguish who

To judge "who is withdrawing," the daily-frequency evidence is only three things: institutional special seats on the dragon-tiger list, counterparties in block trades, and changes in Stock Connect holdings. On November 6, 79 stocks across the market appeared on the dragon-tiger list, and Zhongji Innolight was not among them; the most recent block trade was on October 20, and there was not a single one from November 3 to 6. On the day of "institutions are selling" there is no verifiable trace whatsoever—conversely, "institutions are not selling" cannot be proven either.

On November 3 the stock fell 12.69%; that evening from 21:00 to 22:00 the company held a conference call, with more than 150 institutions on the attendance list, from E Fund to BlackRock, Millennium, and Point72 all present. Management opened by denying two things: overseas customers cutting or canceling orders, and "a certain foreign brokerage downgrading its rating and target market value," and said the latter was "false content spread by someone impersonating that brokerage's name."

On November 6, the company issued another announcement, No. 2026-107, reiterating that revenue for the first three quarters was 695.47 yi yuan and net profit attributable to the parent was 222.38 yi yuan, and that major customer orders "have basically covered the full year of 2027"; in an announcement the same day, the 565.31 wan shares repurchased from September 1 to 23 (accounting for 0.48% of total share capital, at an average price of about 884 yuan) are planned to be fully cancelled, subject to approval by the shareholders' meeting.

Against that day's ChiNext Index -3.96% and CSI 300 -1.44%, Zhongji Innolight's -9.19% was more than twice the ChiNext Index's decline; the selling pressure came from concentrated position reduction under rumors and sentiment, not from some category of funds seeing something not in the financial statements.

When I would be wrong: if in the 2026 annual report the number of shareholders continues to rise, the combined public fund and insurance holdings among the top ten tradable shareholders drop another notch, and at the same time the margin financing balance as a share of tradable market capitalization returns from 3.35% to above 4%, that would show this November wave was institutions using leveraged positions as cover for distribution, and that treating "sector deleveraging" as the whole reason was wrong.
