Frequently Asked Questions

How does buying on margin work?

Buying on margin means borrowing money from your broker to purchase securities. You deposit a minimum of 50% (initial margin), and the broker lends the rest. You pay interest on the loan. Margin amplifies both gains and losses — a 10% gain becomes 20% on your equity, but so does a loss.

What triggers a margin call?

A margin call occurs when your account equity falls below the maintenance margin requirement (typically 25-30%). If your ,000 position drops to ,667, your equity is only 25% (,667/,667). You must deposit additional funds or sell securities to restore the margin level.

What is total return on a stock?

Total return is the complete gain or loss from an investment, combining price appreciation and any dividends received. For example, if you buy a stock at $100, it rises to $110, and pays $2 in dividends, your total return is $12 ($110 - $100 + $2), or 12%. Always use total return when comparing investments.

What is annualized return?

Annualized return converts a holding period return to a yearly equivalent, allowing fair comparison between investments held for different lengths of time. A 50% total return over 4 years is not 12.5%/year — it's approximately 10.67%/year (calculated as: (1 + 0.50)^(1/4) - 1). Use annualized returns to compare any two investments.
