Stephens Investment Management boosts holdings across Braze, Icon, Axon, Varonis.

General Counsel Susan Wiseman sold 35,000 Braze shares, a move noted in the Braze filing and press coverage separate from Stephens’ increased stake.
Bullish CEO Thomas W. Farley sold 80,000 Bullish shares on May 11, reducing his direct ownership by about half and highlighting ongoing insider activity around the company.
Wellington Management Group LLP increased its Icon Plc stake by about 26.6% to 4,637,137 shares, a position valued at roughly $811.5 million, reflecting a substantialInstitutional commitment alongside Stephens’ position.
Stephens Investment Management Group LLC increased its Varonis Systems stake to 1,992,760 shares (about 1.74%), after purchasing 302,411 shares, underscoring a sizeable institutional betting on the cybersecurity stock.
Axon Enterprise shares held by Stephens rose 24.3% to 103,486, with the company also benefitting from analyst activity, including Piper Sandler reaffirming or upgrading its view with an overweight rating on AXON.
Stephens Investment Management Group LLC went on a buying spree in early 2025, raising its stakes in five companies spanning cybersecurity, public safety, medical research, and crypto. The firm boosted holdings in Braze, Bullish, Icon Plc, Varonis Systems, and Axon Enterprise — all in the first quarter, according to Watchlist News.
The moves signal broad conviction from Stephens across growth and technology names. At the same time, insiders at two of those companies were selling shares — a contrast worth watching.
Stephens lifted its Braze stake by 11.2% to 1,370,986 shares — about 1.2% of the company. It also added to its Varonis Systems position, buying 302,411 new shares to bring its total to 1,992,760. That equals roughly 1.74% of the cybersecurity firm. Both moves came during the first quarter, according to Watchlist News.
Stephens also raised its Axon Enterprise position by 24.3% to 103,486 shares. Axon makes tasers and police body cameras. In Icon Plc, a medical research company, Stephens grew its stake by 10.3% to 599,176 shares. Its Bullish position jumped 38.6% to 1,178,599 shares, equal to about 0.78% of the float.
Even as Stephens was buying into Braze, the company's General Counsel Susan Wiseman sold 35,000 Braze shares. Insider sales don't always signal trouble, but they can reflect personal financial planning or a view on valuation. The timing stands out against Stephens' bullish move.
At Bullish, CEO Thomas W. Farley sold 80,000 shares on May 11 — cutting his direct ownership roughly in half. That's a large reduction for a top executive. Stephens, meanwhile, had already boosted its Bullish stake by 38.6% in the prior quarter. Institutional buyers and company leaders were moving in opposite directions.
Stephens isn't alone in piling into Icon Plc. Wellington Management Group LLP raised its Icon stake by 26.6% to 4,637,137 shares. That position is worth roughly $811.5 million. Wellington is one of the world's largest asset managers, so a move that size carries real weight.
Stephens holds far fewer Icon shares — 599,176 — but its 10.3% increase points in the same direction. Icon runs clinical trials and medical research for drug companies. Big institutional buyers often see it as a steady, lower-risk name in the life sciences space.
Stephens grew its Axon Enterprise stake by 24.3% to 103,486 shares. The timing lines up with positive analyst attention. Piper Sandler reaffirmed an overweight rating on Axon — meaning analysts there think the stock will beat the market. An overweight rating is Wall Street's way of saying
