I’d pick C. 💡 If there’s no USD cash available to settle a US stock purchase, the position can result in a USD margin loan, with interest potentially accruing on the borrowed amount. The key lesson: having AUD cash doesn’t automatically mean you have USD cash available without financing implications.

b, gives you a loan to buy it

c, tiger broker will lend you the usd to buy, but charge interest until you convert your aud to usd or use the auto fx conversion feature

b , different stocks have different risks profiles for tiger brokers

D as all those things increase risk to tiger brokers loan

B — A USD 300 loss. 📉 You shorted at $100 and bought back at $130, losing $30 × 10 shares = $300. With a short position, you lose when the stock price rises.

C — USD margin loan. 💵 If there’s no USD cash available to fund the U.S. stock purchase, the trade can create a USD borrowing balance, and interest may accrue. The key is that holding AUD doesn’t automatically mean you have USD available without a currency conversion or financing cost. 📊

B — Lower margin requirement. 📊 The position sizes are identical, so the difference comes down to how much margin the broker requires for each stock. Lower requirement = less collateral needed. 💡

D — All of the above. 📉 A leveraged position falling in value reduces your equity, higher margin requirements raise the amount you need to maintain, and withdrawing cash reduces your safety cushion. Any of these can bring an account closer to a margin call.

D — All of the above. A margin call is not simply about a stock price falling. The real risk is whether your Excess Liquidity (EL) remains above the required level. A leveraged position falling can quickly reduce your equity. But higher margin requirements, cash withdrawals, new leveraged positions, exchange-rate moves, and excessive concentration can also push your account toward liquidation. The key distinction is simple: EL tells you how close you are to liquidation, while AEE tells you whether you have room to open new positions. The biggest lesson? Leverage magnifies both gains and losses. Don’t wait for a margin call notification—monitor your risk level continuously and keep enough liquidity to survive a sharp market move. @Tiger_AU

Answer D: all of the above

A margin call is a demand for additional margin. When a margin account's net assets or risk level no longer meet the maintenance margin requirement, a user may need to: add cash or eligible assets; repay part of the financing; or reduce existing positions.

C. AUD10,000

My view: this is a very important point for beginners to understand. A margin limit is NOT borrowed money. For example: Margin limit: AUD 50,000 Actually borrowed: AUD 10,000 Interest is charged on: AUD 10,000 only So simply having a large margin limit does not mean you are paying interest. However, margin trading is risky. If the stock falls sharply, you may lose more money and could face a margin call. My advice: If you are a beginner and investing for the long term, avoid using margin unless you fully understand the risks. Quiz answer: C — AUD 10,000.

Replying to @moliya:B.USD 300 Loss//@moliya:300loss

300loss

B. A USD 300 loss. You short-sell 10 shares at USD 100, receiving USD 1,000. When the price rises to USD 130, buying back those 10 shares costs USD 1,300. Loss = USD 1,000 − USD 1,300 = −USD 300. Borrowing the shares does not protect you from losses. A short seller profits when the share price falls and loses when it rises. This also highlights the key risk of short selling: the potential loss is theoretically unlimited because a stock price has no fixed upper limit.
