What to make of it
Several insiders buying the same stock in the same week is the single pattern that has held up best in the historical event study — not because insiders are always right, but because a purchase is voluntary and a coincidence of several is rarer than a coincidence of one. Look at where the buys sit on the chart above: purchases into a fall say something different from purchases into a rally.
