CANSLIM in plain English: William O'Neil's checklist

What each letter means, why the fundamental half matters more than the chart, and where the method struggles.

O’Neil’s contribution was insisting that the best-performing stocks share measurable traits before they perform. CANSLIM is the checklist.

  • C — Current earnings. Sharp quarterly earnings growth, accelerating.
  • A — Annual earnings. Consistent growth over several years.
  • N — Something new. New product, new management, new high.
  • S — Supply and demand. Smaller float, volume expanding on the up moves.
  • L — Leader, not laggard. Buy the strongest name in a strong sector.
  • I — Institutional sponsorship. Funds accumulating, but not yet crowded.
  • M — Market direction. Most stocks follow the index; don’t fight it.

The part people get wrong

CANSLIM is usually reduced to the cup-with-handle chart pattern. That’s the smallest part of it. The screen is fundamental; the chart only tells you when.

Your own take goes here — how you’d adapt the earnings screens to Indian quarterly reporting.
