Some of the most interesting opportunities on the ASX tend to appear when confidence is low.
That does not mean every fallen share is a bargain. But I think the three shares in this article have been sold down heavily while still retaining strong long-term growth potential.
For patient investors, I think they are worth buying right now.

DroneShield Ltd (ASX: DRO)
DroneShield has been one of the more volatile ASX growth shares. Although its shares are up 150% over the past 12 months, they remain down by over 50% from their 52-week high.
That volatility is not surprising. The company operates in a fast-growing defence technology market, with expectations high and recent headlines adding uncertainty.
But I do not think it changes the long-term need for counter-drone technology.
Drones are now part of modern conflict, border security, critical infrastructure protection, airport planning, and public safety. They are cheap, flexible, and increasingly capable. That creates a growing need for systems that can detect, track, and respond to drone threats.
DroneShield is trying to solve that problem.
The road may stay bumpy, but I think the long-term defence theme is too powerful to ignore.
CSL Ltd (ASX: CSL)
CSL is a very different case. The healthcare giant has lost a lot of investor trust after a difficult period. Guidance downgrades, execution concerns, and weaker sentiment have pushed the shares far below where they once traded.
I think the sell-off has created a recovery opportunity.
CSL still owns valuable global healthcare businesses across plasma therapies, vaccines, and specialist medicines, which are linked to long-term medical demand.
The company clearly has work to do. It needs to restore confidence, improve consistency, and prove that its earnings can recover.
But the market now appears to be treating CSL as if its problems are permanent. I do not think they are.
The dividend yield has also become more appealing after the share price fall. That gives investors some income while they wait for the recovery to unfold.
WiseTech Global Ltd (ASX: WTC)
WiseTech is another fallen ASX share I would be happy to buy.
The company builds software for global trade and logistics, which is one of the most complex parts of the world economy.
Moving goods across borders involves customs, compliance, documents, tariffs, warehouses, carriers, and regulation. WiseTech's software sits inside those workflows.
That creates a strong position if customers continue relying on the platform to manage more of their operations.
I also think artificial intelligence could make WiseTech more useful over time rather than disrupt it. Logistics involves repetitive documents, exception handling, classification, and workflow decisions. Smarter software could reduce manual work and increase customer value.
The stock has risks around valuation, acquisitions, and execution. But after such a large fall, I think the buying case looks far more interesting.
Foolish Takeaway
These shares are not without risk. DroneShield faces governance, disclosure, and regulatory uncertainty; CSL has damaged confidence; and WiseTech has questions to answer around execution and valuation.
But for investors willing to think in years rather than months, I think these three beaten-down ASX shares could be worth buying while sentiment remains weak.
