Combining Fundamentals with Momentum

Pure momentum — buying whatever is going up without any fundamental filter — works until it spectacularly fails. The most durable momentum strategies combine technical timing with fundamental quality filters to eliminate the weakest momentum candidates.

Why This Matters

O'Neil's CANSLIM system is the most widely documented framework for combining fundamental and technical analysis in momentum investing. The C (Current quarterly earnings), A (Annual earnings growth), N (New products/markets/highs), S (Supply/demand), L (Leader in its sector), I (Institutional sponsorship), M (Market direction) criteria integrate fundamental quality filters with momentum and market timing. The result is a momentum approach that rejects technically strong charts driven by poor fundamental quality.
