Wildcat Resources Ltd (ASX: WC8)
The Wildcat Resources share price is steady at 51 cents, up about 215% over FY26.
Arthur Garipoli from Dolphin Partners Financial Services has a buy rating on this ASX lithium share.
Garipoli said:
Wildcat is a mineral exploration company. WC8 is advancing the Tabba Tabba Lithium-Tantalum project and the Bolt Cutter project in the Pilbara region of Western Australia.
The Tabba Tabba project is a large scale, hard rock development in an established mining jurisdiction with low sovereign risk and close to Port Hedland infrastructure. WC8 has completed a pre-feasibility study and is advancing towards a definitive feasibility study (DFS).
Catalysts for de-risking the company include a large resource base, a DFS, funding and resource growth.
The shares have performed strongly in the past 12 months and we like the company's outlook.
WiseTech Global Ltd (ASX: WTC)
The Wisetech share price is $32.76, up 4% today and down 70% over FY26.
Stuart Bromley from Medallion Financial Group has a hold rating on this ASX 200 tech share.
Bromley said:
Despite ongoing management and governance scrutiny, WiseTech remains one of Australia's highest quality technology businesses with a dominant position in global logistics software.
The company's CargoWise platform continues to gain market share globally.
In our view, WTC offers a substantial long term growth opportunity.
While near term sentiment may remain volatile, we believe the quality of the underlying business warrants a hold rating amid management executing its long term strategy.
National Australia Bank Ltd (ASX: NAB)
The NAB share price is $37.71, up 0.5% today and down 4% over FY26.
Michael Gable from Fairmont Equities has a sell rating on this ASX 200 bank share.
Gable said:
Trading conditions are getting tougher for retail banks as rising interest rates, sticky inflation and weakness in the property sector are likely to negatively impact lending activity and credit quality.
In a weaker economy, NAB is particularly vulnerable to softer earnings growth due to its higher focus on business banking.
Despite a significant share price fall, NAB valuations aren't cheap, leaving the stock exposed to downside risk.
