Methodology: each issue's direction is a live signal — long/short opens or holds a position, neutral means flat, and every direction change opens, flips, or closes it. Returns are direction-aware (a short gains when the price falls) and compound across positions from first observation to the latest issue. "Price move" is the stock's own raw change, shown separately. Neither represents actual portfolio performance.
