Cash vs margin concepts
Borrowing to buy securities: power and failure modes — concepts only. Education only — not a recommendation to buy, sell, or hold anything.
Margin buying (idea)
You may buy more than cash alone allows by borrowing against eligible securities. Upside and downside both scale. Interest may accrue.
Maintenance and forced selling (concept)
- If equity drops too far, you may face a margin call.
- Positions can be sold without your preferred timing.
Shorting link
Margin infrastructure also relates to short selling mechanics (borrow, locate). More in Trading ops.
Literacy rule
Margin is a tool with liquidation risk — not a personality upgrade. Fake-money practice only on this lab.
Practice tip: Feel sizing stress with fake money on /mock/; revisit Position sizing concepts.
