– 📍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 be able to normally. To trade on margin, you need a margin account. This is different 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 the purchase price that you deposit is known as the initial margin. It’s essential to know that you don’t have to margin all the way up to 60%. You can borrow less, say 10% or 25%. For example, a listed company’s stock “A” is currently trading at 100 per share. At this time, 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 at this time. For this stock, Its Margin Multiplier is 60%, 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 buy them back 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 buys the shares back 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 charged by the broker or commissions charged 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.

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
