Why it Matters?

Action against independent self-interest is the most probative factor, since conduct that would be irrational absent coordination is the strongest circumstantial evidence, and rebutting it requires demonstrating a business rationale for the challenged behavior. Opportunity to conspire through trade association meetings is the weakest factor standing alone, since lawful industry gatherings are ubiquitous. Weighting the factors rather than counting them is the analysis.
