Question 1

What is stock pledging, and how are loan-to-value (LTV) and maintenance ratios calculated?

Accepted Answer

Stock pledging allows investors to use held shares as collateral for cash loans.

Formulas:
① Max Loan Amount:
Total Stock Market Value × Pledge Ratio (usually up to 60% in Taiwan).

② Maintenance Ratio (%):
(Current Total Stock Value ÷ Total Loan Amount) × 100%.

For instance, pledging $1M in stock to borrow $600K results in an initial maintenance ratio of 166.7%.

Question 2

What happens when the maintenance ratio falls below 130%? What is a Margin Call and Liquidation?

Accepted Answer

Margin calls and liquidation mechanisms:

① Margin Call:
If market drops reduce collateral value below 130%, brokers issue a margin call requiring additional cash or shares within 2 business days to restore maintenance above 166%.

② Forced Liquidation:
Failing to meet margin calls results in brokers forcibly selling pledged shares at market open on the 3rd business day.

Question 3

How is the 130% Margin Call Threshold Stock Price calculated?

Accepted Answer

Margin Call Price Formula:

① Formula:
Margin Call Price = (Total Loan Amount × 1.3) ÷ Total Shares.

② Example:
Borrowing $600,000 against 1,000 shares yields a threshold price of ($600,000 × 1.3) ÷ 1,000 = $780. Our calculator automatically computes and displays this threshold.

Question 4

How can investors increase their maintenance ratio during a market crash?

Accepted Answer

Three common strategies:

① Repay Loan Principal:
Directly reduces loan amount (denominator), rapidly elevating maintenance ratio.

② Deposit Additional Collateral Shares:
Transfer other eligible stocks into the pledge account to increase total collateral value (numerator).

③ Deposit Cash Margin:
Deposit cash directly into the margin account as required by brokers.

Question 5

What are the leverage risks of stock pledging? What does broker "umbrella recall" risk mean?

Accepted Answer

Stock pledging is inherently leverage. During market crashes, collateral value drops rapidly, accelerating margin call risks.

Crucially, beware of broker "umbrella recall" risks:
① Refusal to extend or demanding early repayment:
Brokers retain full discretion to deny loan extensions upon 6-month term expiration, especially during market turmoil or when total lending quotas are reached.

② Floating interest rate hikes:
Brokers may adjust pledge interest rates based on market capital costs.

Always maintain conservative leverage and reserve liquidity!

Question 6

Are calculation results identical across all brokers and banks? (Disclaimer & Variations)

Accepted Answer

Results provided by this tool are for estimation and reference only. Please refer to your broker's official statements for actual settlement numbers.

Variations between institutions include:
① Reference Price for Maintenance Ratio:
Some brokers use previous day closing prices, while others use real-time intraday or daily closing prices.

② Pledge Ratio Caps:
High-volatility or small-cap stocks may have lower pledge ratios (e.g. 40%–50% instead of 60%).

③ Fees & Charges:
Origination fees or wire transfer costs are excluded from calculations.

Question 7

Who receives dividends and stock distributions during stock pledging?

Accepted Answer

Dividends and stock splits belong 100% to the borrower!

The borrower retains underlying stock ownership throughout the pledge term. Cash dividends are deposited into your settlement account.

Question 8

How is pledge loan interest calculated, and what is the maximum loan duration?

Accepted Answer

Interest and loan duration:

① Interest Calculation:
Interest is calculated daily (Annual Rate ÷ 365 × Days) and settled semi-annually.

② Term & Extensions:
Standard terms are 6 months, expandable up to 1.5–2 years upon request provided maintenance ratios remain healthy.
