What is the 7% rule in stocks ?

The 7% rule could save your portfolio from catastrophic losses — this is the risk-management strategy every trader needs to understand before their next trade.

If you've ever watched a small loss spiral into a portfolio-wrecking disaster, this video is for you. We break down William O'Neil's famous 7% rule from his CAN SLIM investing methodology — a simple, mechanical stop-loss guideline that tells you exactly when to cut a losing position. No guessing, no emotional decision-making, just a clear threshold designed to protect your capital before small losses compound into unrecoverable ones. We'll walk through the math that makes this rule so powerful, why O'Neil settled on 7-8% specifically, and how different types of traders and investors apply it differently based on their strategy and timeframe.

What you'll learn in this video:

What the 7% rule actually is and where it comes from
The math behind why smaller losses are easier to recover from
How growth and momentum traders use this stop-loss rule strictly
Why value and dividend investors often widen or skip this threshold
How day and swing traders tighten the rule for shorter timeframes
Why position sizing matters just as much as the stop-loss percentage
The limitations of this rule — and why it's a heuristic, not a scientific law

Whether you're a short-term trader chasing breakouts or a long-term investor building wealth patiently, understanding this risk-management principle will change how you think about exits. We also cover real examples of when this stop-loss approach helps — and when it can backfire.
