Director Robert Holmes Swan purchases $746K in ADP shares, extending six open-market buys in 36 months while stock trades well below 52-week highs.

Robert Holmes Swan, a director at Automatic Data Processing, purchased a substantial block of shares at a price that represents a significant discount to the company's 52-week high, adding to holdings that already exceeded four times his previous position from this single transaction. What distinguishes this trade is Swan's consistent pattern of open-market purchases—this is his sixth purchase in the past three years with zero open-market sales, indicating sustained conviction through both stronger and weaker periods. ADP remains a profitable company with solid revenue growth and a reasonable valuation multiple, providing a financially stable backdrop for the purchase. Swan's prior open-market purchases have demonstrated strong subsequent performance, with three-quarters of those trades showing gains within a quarter, suggesting his timing on similar moves has historically been sound. The combination of a director's repeated buying at discounted valuations, paired with his track record of well-timed entries, underscores why institutional investors track these transactions closely.
