Hard rules

• CANSLIM: Current earnings, Annual earnings, New (product/high), Supply/demand, Leader vs laggard, Institutional sponsorship, Market direction
• Buy proper breakouts (e.g. cup-with-handle, tight bases), not falling knives
• Never average down a losing growth name; cut around 7-8% as discipline
• Individual setups fail if the general market is under distribution

Looks at

Kills the thesis if

• laggard in a leading group
• breakout on weak volume
• market in correction and this is not a leader
• earnings deceleration dressed as a "base"
