3 Great Growth Stocks To Own In October 2026

AI related demand has pushed Samsung and TSMC to record chip profits, reminding investors how quickly growth stories can reshape entire sectors when capital and customer interest line up. The same logic applies to companies that analysts expect to lift revenue and earnings sharply over the next three years, while keeping their balance sheets robust. This article highlights three such high potential stocks from the screener that fit that profile.

The three stocks in focus below are just a sample. The full screen surfaced 85 more companies with similarly ambitious growth profiles and balance sheets that can carry that plan. If you want to identify and analyze the highest conviction ideas in that wider group, head straight into the Best high growth potential screener.

Credo Technology Group Holding (CRDO)

Credo Technology Group Holding taps straight into the screener theme through its high-speed connectivity hardware for Ethernet and PCIe, which underpins rising data-center and AI infrastructure demand that analysts link to strong potential revenue and earnings expansion.

Credo generates about US$1.6b of semiconductor revenue from this connectivity focused portfolio and the stock carries a market value around US$41.4b. This puts it firmly in large cap territory for investors watching the growth story.

"The DustPhotonics acquisition gives Credo a weapon to fight in this longer-range, higher-bandwidth territory that was previously Marvell's exclusive domain."

There is also the question of what happens if single customer concentration pressure or a change in high-speed interconnect buying patterns starts to test those growth assumptions.

If that concentration risk is what you are weighing, the full narrative for Credo Technology Group Holding shows how Credo balances customer exposure with its Ethernet and PCIe ambitions.

Ionic Digital (IOND)

Ionic Digital leans directly into the Best high growth potential theme through its West Texas high performance computing and AI infrastructure leasing platform, with additional exposure from its cryptocurrency mining activity.

Ionic Digital runs digital infrastructure solutions and cryptocurrency mining, with about US$69 million from crypto mining and segment adjustments of roughly US$94 million, all currently tied to the United States, and the stock valued around US$3.7b in market cap.

Ionic Digital gives you a pure play on AI focused power and compute capacity, where long leases and utility scale sites can turn contracted demand into cash flow.

"Conversion of 323MW at Ward County into a 10 year triple net lease with contracted rent of about US$183m a year and 3% annual escalators after year 5 sets up Ionic Digital for a larger share of revenue from long dated, high margin leasing income."

What really matters now is how one concentrated source of demand ultimately shapes those future margins and the growth runway investors are paying for.

That concentration question is exactly where the story gets interesting, and the full narrative for Ionic Digital unpacks how Ionic Digital’s leasing model could accelerate or cap that upside.

Lumentum Holdings (LITE)

Lumentum Holdings plugs directly into the Best high growth potential theme through its optical components that help move huge volumes of data for cloud and AI workloads, which is why investors are watching how far this demand cycle can run before it cools.

"The tension: cloud optics revenue is tied to hyperscaler CapEx cycles, which have historically been boom and bust. If training-cluster buildout peaks and inference networking does not fill the gap, revenue growth could decelerate sharply."

What matters next is whether one crucial shift in demand mix quietly reshapes margins just as expectations for long runway growth peak.

That inflection point in mix and pricing is exactly what the full narrative for Lumentum Holdings unpacks, highlighting where Lumentum Holdings could see margins accelerate or cyclical risks quietly build.
