These 3 S&P/ASX 200 Index (ASX: XJO) shares have taken a hit lately.
CSL Ltd (ASX: CSL), WiseTech Global Ltd (ASX: WTC) and Megaport Ltd (ASX: MP1) all started 2026 with big losses – 15%, 31% and 28% respectively at the time of writing.
But what ties the 3 ASX 200 shares together isn't trendy momentum, it's industry leadership and long-term cash generation potential. All hallmark traits Warren Buffett prizes.

CSL: Healthcare dominance with a value twist
This $71 billion ASX 200 share is a global leader in plasma-derived therapies with one of the tightest moats on the ASX. It's anchored by its scale, regulatory barriers and long R&D runway.
CSL controls a sizeable share of global plasma collection centres, giving it pricing and margin advantages in a consolidated market. Long-term growth in immunoglobulin demand — driven by ageing populations and wider diagnosis — underpins robust revenue potential.
On the flip side, the market hasn't been kind recently. Shares are trading well below their recent peaks as near-term guidance was trimmed. Uncertainty around its vaccine arm and restructuring has also weighed on sentiment.
Never mind the short term noise, CSL's fundamentals remain intact. It has steady cash flow, pricing power and a diversified product mix. If you believe in long-term healthcare megatrends and that temporary operational challenges resolve, CSL's valuation dip could reflect a moat on sale, not a moat broken.
Warren Buffett likes predictable cash flows; CSL still fits that bill for patient holders.
Brokers see plenty of upside. The average 12-months price target is set at $209.77, a potential gain of 43% at current levels.
WiseTech: Logistics software at a crossroads
WiseTech's CargoWise platform is deeply embedded in global freight and logistics operations. It creates a compelling network effect that's hard for competitors to replicate. Even after a hefty share price drop, its revenue base has shown resilience and earnings growth potential.
The company's recent history has been messy. Governance questions surrounding founder leadership and high-profile controversies pushed institutional sellers out, eroding investor confidence. And now, ASX 200 tech share is executing a dramatic pivot by cutting roughly a third of its workforce as it weaves AI into its core offerings. That's a bold strategic shift, but one that introduces execution risk and near-term volatility.
If WiseTech can translate its brand strength and platform ubiquity into a leaner, AI-enabled growth engine, the current valuation may offer asymmetrical upside for long-term holders.
Most analysts see WiseTech as a buy or strong buy with a price target of $83.92. That points to a 77% upside over 12 months.
This stock might be a bit more speculative than Warren Buffett's usual safe compounders. However, it's a quality company with an overlay of transformation risk.
Megaport: Cloud connectivity riding the digital backbone
This ASX 200 share sits at the heart of global multicloud networking. Megaport offers on-demand connectivity between enterprises and major cloud providers. That's a structural growth story as companies move computing workloads off-premise.
Its flexible SaaS model and recurring revenue are Buffett-friendly features that favour disciplined capital allocation and predictability.
Megaport isn't yet a cash machine the way Buffett's favourite names are. Earnings are still evolving, and it has a longer path to sustainable profitability.
If you're in for the multi-year cloud adoption story, Megaport's infrastructure play feels like an underappreciated sibling to the big cloud giants. Brokers seem to think so. They think that the ASX 200 share will deliver a potential plus of 81% at $15.91 over 12 months.
Warren Buffett might balk at its early-stage earnings story today, but the underlying secular trend is durable. Especially if you're stacking positions over time rather than timing swings.
