🔸Introduction🔸

TEJ [Chip Database] provides various information related to securities and chips, ranging from legal person transaction information, holding costs, broker entry and exit details, the spread of shareholdings under TDCC custody, and margin trading to securities borrowing and lending. With up to 35 sub-blocks, users can experience the most complete and accurate Taiwan securities chip information. This chapter, [Margin Trading]will be divided into three parts. The first part will guide readers in a simple and unburdened way to learn how to operate the [Margin Trading] database. It collects information on margin trade, securities borrowing, and lending, as announced by the Taiwan Stock Exchange and OTC Center daily. Second, after users are familiar with the operation of the database, they can further use the data to derive and construct models. Third, we will continue to lead you to dig deeper into the [Margin Trading] database, including sub-blocks in credit transactions and many chip databases, all providing more detailed information on credit transactions.

📍How to apply the Margin account?

1. The customer is a citizen of the Republic of China who is 20 years of age or older and who is not incapacitated or a juristic person incorporated and registered under the law of the Republic of China.
2. The customer has opened a consignment trading account for at least three months.
3. The customer settled 10 or more consignment trading transactions during the most recent year with an accumulated transaction value of 50% of the amount limit for margin purchase applied for. This also applies to a consignment trading account opened for less than one year.
4. The sum of the customer’s income received and various other properties during the most recent year is at 30% of the amount limit for margin purchase applied for, except where the amount limit for margin purchase applied for is less than NT$500,000.

📍What’s Margin Trading?

(1) Margin Purchase
Buying on margin is borrowing money from a broker to purchase stock. You can think of it as a loan from your brokerage. Margin trading allows you to buy more stock than you’d typically be able to buy. To trade on margin, you need a margin account. This differs from a regular cash account, in which you trade using the money in the account. Once the account is opened and operational, you can borrow up to 60%(Listed 60%, OTC 50%) of the purchase price of a stock. This portion of your deposit purchase price is known as the initial margin. Knowing that you don’t have to margin up to 60% is essential. You can borrow less, say 10% or 25%. For example, a listed company’s stock “A” trades at 100 shares. Now, you think it will still grow and have to buy it immediately. Unexpectedly, the funds are insufficient, so you can use Margin Purchase to buy now. Its Margin Multiplier is 60% for this stock, and you need to have 40% of your own funds. Therefore, when you use Margin Purchase to buy this stock, you only need to pay NTD 40,000 and pay the Margin Purchase interest. The annual interest rate of the Margin Purchase interest rate is about 6–7% per year(calculated on a daily basis).

Margin Multiplier = 60%
Margin Purchase interest rate = 6–7%
Margin Purchase interest = Margin Purchase x interest rate x days ÷ 365(days)

(2) Margin Short sales
With short selling, a seller opens a short position by borrowing shares, usually from a broker-dealer, hoping to repurchase them for a profit if the price declines. Shares must be borrowed because you cannot sell shares that do not exist. To close a short position, a trader repurchases the shares on the market — hopefully at a price less than what they borrowed the asset — and returns them to the lender or broker. Traders must account for any interest the broker charges or commissions on trades. To open a short position, a trader must have a margin account and will usually have to pay interest on the value of the borrowed shares while the position is open.

Margin Short sales Multiplier = 90%
Short sales margin = Margin Short sales x stock price x 90%
Margin Short sales interest rate = roughly 0.1–0.4%
Margin Short sales interest = Short sales margin x Margin Short sales interest rate x days ÷ 365
