Key takeaways

Generation Development leadership trims warchest: William Bessemer, who has led the company through multiple roles since joining in 1995 (when it was known as Austock), recently sold 192,000 shares near record levels. Despite the timing, the transaction represents just 1.6% of his total holding, leaving him with 11.47 million shares. Bessemer's long tenure includes serving as Chairman from 1999 to 2009, returning as CEO in 2012, and stepping down from the executive role in 2017 while remaining a Non-Executive Director.

REA chief makes modest exit ahead of retirement: CEO Owen Wilson, who announced in February his plans to retire from full-time executive duties in the second half of 2025, sold a small 2,522-share parcel last week. The sale represents approximately 3.75% of his total shareholding, leaving him with 67,155 shares after a decade with REA and six years as CEO.

Dicker Data executives buy the dip: Shares in the IT distributor are trading near five-year lows following a double blow — founder and CEO David Dicker's announced departure (preceded by a $67 million selldown three days earlier) and a disappointing trading update showing weaker margins despite stronger revenue growth. The margin pressure reflects a shift toward lower-margin sales, though UBS, JPMorgan and Goldman Sachs analysts remain optimistic given current valuations, looming rate cuts, and potential recovery in the small-to-medium business segment. Interestingly, Chief Operating Officer Vladimir Mitnovetski and Chief Financial Officer Mary Stojcevski both purchased $30-60,000 parcels last week.
