✨Prop desk traders’ shareholding ratio✨
The formula for Prop desk traders’ shareholding ratio is as follows:
Individual stock: Prop desk traders’ shareholdings/Outstanding shares
Industry: Prop desk traders’ holding market value/Total holding market value
The problem that users often encounter is the calculation of the number of stocks held by the Prop desk traders. Here, we will take readers to use our TEJ Pro database to verify it. First, we can see that the algorithm for the number of stocks held by the Prop desk traders is as follows:
Estimate the number of treasury stocks and stocks bought and sold every day by the Prop desk traders. The number of treasury stocks before March 2008 is provided by TWSE. However, after March 2008, the TWSE ceases to provide monthly stock quantity. Therefore, we are currently using the weekly trading in and out to estimate the number of treasury stocks at the end of the month. We will use financial statements for correction every six months.
It can be seen from the description that the number of stocks held by Prop desk traders is estimated from the monthly inventory and the buying and selling of the Prop desk traders. Take TSMC (2330) as an example, From the figure below, we can see that on July 30, 2020, the number of stocks held by the Prop desk traders is 1,658, but on July 31, it becomes 0.
Users often have questions when they see the numbers. This is because at the end of the month, we will calibrate the number of stocks of Dealer Holding (Monthly)-ALL database. As shown in the figure below, it can be seen that on 2020/7, the number of stocks is 0.
Therefore, on 2020/7/31, the number of stocks held by Prop desk traders will be calibrated to 0, and starting from 8/1, the number of stocks will be calculated from 0 plus the daily change in buying and selling.
As you can see from the figure above, on 8/3 there is a number of transactions 327, the number of Prop desk traders shareholdings will be 0+327 = 327.
Next is the part of the adjustment based on the financial report every six months. We can see that the number of stocks held by the Prop desk traders is 3,629 on June 29, 2020, and the number of stocks held by 6/30 should be 3629+503 = 4132, but the number is 5,643, as shown in the figure below:
This is because the number will be adjusted according to financial report every six month. The number will be 5,643.
Here is how to check the Prop desk traders’ shareholdings in the financial report. Take Yuanta Securities (000980) as an example, you can go to MOPS for inquiries.
1️⃣ Click basic information — Electronic books — Financial report.
2️⃣ Enter Jih Sun securities code 000116 and year 109.
3️⃣ Click on the electronic file of the IFRS individual financial report for 2020Q2.
4️⃣ You can find that Yuanta have 1,021 shareholdings of TSMC.
Finally, we can add up the number of TSMC shareholdings by each Prop desk trader in 2020Q2, and we can get the number of 5,643. If you are interested, you can go to other securities firms to sum up the number of shares to verify.
Once we have the number of shares held by the Prop desk traders, we can calculate the shareholding ratio. The calculation method of shareholding ratio in 7/30 is 1658/25930380 = 0.01% and in 7/31 is 0/25930380 = 0%
In this article, we introduce the calculation method of Prop desk traders’ shareholding ratio. We have completely introduced the algorithms of the respective shareholding ratios of the three major legal institutions through these three articles. Investors can use these data to understand the changes in the stock market when doing bargaining chip analysis. We hope that every reader can have a deeper understanding through our articles.
