ECPND means Earnings Call Participation Network and Dynamics. ECQDI means Earnings Call Quantitative Dynamics and Intensity. They are distinct research inputs. Published historical return differences depend on the universe, baseline, costs and timing. They are not guaranteed returns, risk-adjusted alpha or live performance. Cite the holding horizon, baseline and paper's update date. Roadmaps are targets, not guaranteed outcomes.
