Key takeaways
Dicker Data: Insiders continue buying as shares hover near five-year lows following founder David Dicker's departure announcement and a $67 million selldown three days prior. In addition, a disappointing trading update (21-May) flagged weaker margins despite revenue growth. However, the stock appears to be stabilising around $8, with insiders including COO Vladimir Mitnovetski adding parcels over the past month. Most analysts maintain Buy ratings, with UBS retaining its 'Buy' rating despite the weak update, noting the stock "seems reasonably attractive at 16x CY26 PE" given potential SMB sector recovery from rate cuts.
Mader Group: CEO Justin Nuich purchased 2,500 shares last week, lifting his stake by 0.3% to 859,960 shares. Despite the company guiding to FY25 net profit of "at least $57 million" (up from $38.5 million in FY23), shares have traded sideways since August 2023. Mixed first-half results showed record revenues but margin pressure from labour market challenges and a 15% decline in North American revenues, which represent approximately 20% of group sales.
All other transactions involved Non-Executive Directors.
