Simple Definition

An order to sell automatically if a stock drops to a certain price.

Why It Matters

Stop losses are your automatic ejection seat. You buy a stock at $100 and set a stop loss at $90 - if it drops to $90, it sells automatically, limiting your loss to 10%. Professional traders rarely enter a position without knowing their exit point. It removes emotion from the 'should I sell?' decision during scary drops.

Key Points

  • Common strategy: Set stop loss 10-15% below purchase price to limit downside
  • Trailing stop loss: Moves up with the stock price, locking in gains while protecting against drops
  • Warning: Stop losses can trigger on temporary dips - a stock might hit $90, trigger your sell, then bounce back to $110
