WiseTech Global Ltd (ASX: WTC)
The WiseTech share price is $37.11, down 3.4% today and down 46% in the calendar year to date (YTD).
Bell Potter reiterated its buy rating on this ASX 200 tech share but cut its 12-month price target last week.
The broker said:
WiseTech CEO Zubin Appoo said at the 1HFY26 result in February he was "confident and hopeful" that the company would migrate some of the remaining 5% of customers – representing c.30% of CargoWise revenue – across to CargoWise Value Packs (CVP) this financial year.
As of yet, however, there has been no announcement or indication that one or more of these customers have moved across so we suspect it is proving more difficult or at least more time consuming to achieve this outcome.
As a result we are modestly reducing our CargoWise revenue forecasts in the short to medium term given we expect this transition to provide a boost to revenue with the shift to transaction-based pricing.
We also see some risk that WiseTech may have to provide greater incentives for these customers to shift – such as transitional price
protection (TPP) or additional training – which would also have a negative impact.
Bell Potter reduced its 12-month price target from $78.75 to $71.75.
Ampol Ltd (ASX: ALD)
The Ampol share price is $34.17, up 1.1% today and up 6% YTD.
Andrew Wielandt from DP Wealth Advisory has hold rating on this ASX 200 energy share.
Wielandt commented on The Bull:
Ampol is Australia's biggest petrol and convenience network. It also owns the Lytton oil refinery in Queensland.
The Middle East crisis is positive for the company's refining margins and earnings growth is expected to continue moving forward. The convenience retail segment provides the benefit of diversification.
A significantly increasing share price in the past 12 months reflects market optimism, so ALD remains a hold at these levels.
Lotus Resources Ltd (ASX: LOT)
The Lotus Resources share price is 59 cents, up 1.2% today and down 72% YTD.
Lotus Resources is a uranium producer. It is developing the Kayelekera mine in Malawi and the Letlhakane project in Botswana.
Elio D'Amato from EnviroInvest has a sell rating on this ASX uranium share.
D'Amato explained:
Uranium plays an important role in reducing global emissions and it's encouraging the Kayelekera mine is moving towards steady-state production.
However, the latest quarterly report highlighted several operational challenges, including lower-than-expected recoveries, re-agent shortages and the withdrawal of previously reported grade and recovery figures while reconciliation processes are reviewed.
The company remains well funded and believes these issues are manageable.
Even so, in our view, operational uncertainty during a critical production ramp-up phase increases risk and warrants a more cautious approach.
