Catapult Sports Ltd (ASX: CAT)
According to a note out of Bell Potter, its analysts have retained their buy rating on this sports technology company's shares with a trimmed price target of $4.50. Bell Potter is feeling positive about Catapult's upcoming FY 2026 results. In fact, the broker suspects that Catapult could outperform EBITDA guidance and consensus estimates slightly. It then expects guidance for FY 2027 to be positive. In light of this, the broker continues to rate Catapult as its key pick in the tech sector amongst mid cap stocks. It also sees little risk of AI disruption for the stock given its extensive proprietary data, multiple product platform, and the hardware component to its solutions. The Catapult share price ended the week at $2.94.
Treasury Wine Estates Ltd (ASX: TWE)
A note out of Morgans reveals that its analysts have upgraded this wine giant's shares to a buy rating with a $5.30 price target. The broker has been looking ahead to the Penfolds owner's investor day event next month. It believes this event could be a key share price catalyst, with management detailing plans and targets for its portfolio and operating model. Combined with an encouraging trading update last month, Morgans is feeling more positive on the company's outlook. So, with its shares trading on low trading multiples, the broker thinks now could be a good time to invest. The Treasury Wine share price is fetching $4.25 at the time of writing.
Xero Ltd (ASX: XRO)
Analysts at Macquarie have retained their buy rating on this cloud accounting platform provider's shares with an improved price target of $235.80. According to the note, the broker was pleased with Xero's performance in FY 2026 and particularly its accelerating growth in the key US market. Looking ahead, Macquarie sees potential for significant operating leverage as revenue scales across a largely fixed cost base. And while AI disruption concerns are lingering, the broker believes Xero's proprietary customer data and ecosystem integration positions it well for the future. The Xero share price last traded at $79.67.
