On October 23, 2024, Tokyo Metro Co., Ltd. (code: 9023) made its debut on the Tokyo Stock Exchange, but its shares remained untraded despite a deluge of buy orders. This article explores the factors contributing to the glut of buy orders and the impact of the special matching mechanism on the initial trading dynamics.


Investor sentiment and market anticipation played a significant role in driving the high demand for Tokyo Metro shares. The company's reputation as a major player in the Tokyo metropolitan area, coupled with expectations of strong financial performance, attracted numerous investors eager to acquire the company's shares.

The lack of sell orders and the prohibition of market orders further contributed to the glut of buy orders. On the listing date, sell market orders were prohibited, and no trades were executed, leading to an accumulation of buy orders. This prohibition, combined with the absence of sell orders, created an imbalance in the order book, with buy orders far outnumbering sell orders.


The special matching mechanism implemented for Tokyo Metro's listing had a substantial impact on the initial trading dynamics. The 10-minute quote renewal interval influenced the initial price determination by allowing the upper limit price to be reached gradually. This interval provided time for investors to adjust their orders and for the market to find an equilibrium price.

The upper limit price of JPY 2,760 (230% of the order book center price) impacted the initial price determination process by capping the price increase. This limit prevented the price from skyrocketing due to excessive demand and provided a ceiling for investors to target. The quote renewal rules allowed the price to approach the upper limit in increments of JPY 60, facilitating a more controlled and orderly price discovery process.

The lower limit price of JPY 900 (75% of the order book center price) affected the initial price determination process by setting a floor for the price. This limit prevented the price from falling below a certain level, providing support for the share price and reassuring investors of the company's value.

The prohibition of market orders on the listing date influenced the initial price determination process by encouraging investors to place limit orders. This restriction forced investors to specify the price at which they were willing to buy or sell shares, promoting a more deliberate and thoughtful approach to price discovery.

In conclusion, the listing mechanism for Tokyo Metro Co., Ltd. significantly influenced the initial trading dynamics, with investor sentiment and market anticipation driving the high demand for shares. The lack of sell orders and the prohibition of market orders contributed to the glut of buy orders, while the special matching mechanism, particularly the upper limit and quote renewal rules, played a crucial role in shaping the initial price determination process. The 10-minute quote renewal interval, upper limit price, lower limit price, and prohibition of market orders all had distinct impacts on the initial trading dynamics, ultimately leading to an untraded status for Tokyo Metro shares on its listing day.
