Margin trading

In plain English

Margin means borrowing money from a broker to buy more. Gains and losses get bigger — and you can be forced to sell if the account falls too far.

Everyday analogy: Buying more gear with a credit card — great when prices rise, painful when they fall and the bill comes due.

Why it matters

Margin turns ordinary volatility into survival risk. Forced selling often hits when prices are worst.

A bit more detail (optional)

How leverage works

You put up collateral; the broker lends the rest. A 10% move in the stock is a larger percent move on your equity — both ways.

Margin calls

If the account equity drops below maintenance requirements, the broker can demand cash or sell positions — often at the worst time.

Simple examples

Forced exit

A leveraged long survives a −8% dip but fails a −18% gap. The broker liquidates; the rebound never helps that account.

Margin call cascade

A leveraged long survives mild dips, then a gap breaches maintenance. Liquidation locks in losses before any rebound.

Easy mistakes to avoid

  • Only imagining the upside of leverage
  • Ignoring forced sales after a sudden gap
  • Sizing for the upside only
  • Ignoring maintenance margin and overnight gaps
  • Confusing “I can afford the interest” with “I can survive a gap”

Remember: Margin multiplies outcomes — including the ones you cannot emotionally or financially survive.
