3 Growth Stocks To Own In October 2026

AI spending now powers a big share of US economic growth, with companies pouring money into data centers and infrastructure. That kind of commitment puts a spotlight on businesses that analysts expect to grow earnings strongly while keeping their finances in solid shape. This article walks through 3 stocks from a high growth potential screener that filters for both rapid profit expansion and balance sheet health.

The three stocks that follow are just a sample, and the full screen surfaced 1,576 more companies with similarly strong growth stories and balance sheet profiles that are not covered here.

If you want to move beyond a few examples and quickly identify your own shortlist, head straight into the Healthy high growth potential screener to filter, analyze, and focus on the highest conviction ideas for your watchlist.

Marvell Technology (MRVL)

Marvell Technology leans directly into the Healthy high growth potential theme through its data center networking and storage chips, which sit at the heart of AI-heavy infrastructure spending and give the business meaningful exposure to long-term demand for faster connections and storage acceleration.

Marvell generates about US$9.5b in revenue from designing and selling integrated circuits that power data infrastructure worldwide, with products reaching customers across China, Taiwan, the United States and other regions, and the stock now carries a market value near US$241b.

"NVIDIA's $2B investment (March 31, 2026) into Marvell via NVLink Fusion is not a component deal; it is an ecosystem architecture deal. NVIDIA is financially aligned with Marvell's success."

The real swing factor for Marvell is how that ecosystem alignment translates into long-run pricing power and earnings quality if a single key assumption breaks.

If that core assumption matters to your thesis, read the full narrative for Marvell Technology to see how ecosystem economics, capital intensity and AI demand could be decoupling.

Sandisk (SNDK)

Sandisk is a pure-play on NAND flash storage within the Healthy high growth potential theme. Its flash-based SSDs and embedded storage products drive US$20.2b of data storage revenue globally and support a market value of about US$235.7b.

For the Healthy high growth potential screen, Sandisk provides a direct link to AI data infrastructure through its SSD and NAND portfolio, which is increasingly tied to data center and cloud storage demand.

"Rapid AI and cloud workload expansion is driving data center NAND exabyte growth at a pace well above overall supply, positioning SanDisk's enterprise SSD portfolio and deepening hyperscaler engagements to support sustained revenue acceleration and structurally higher pricing power."

What happens to that earnings story if one key assumption about pricing discipline and supply tightness eventually stops holding up?

If that pricing power hinge matters to your Sandisk thesis, read the full narrative for Sandisk to see how supply cycles, AI demand and margins might be shifting.

Palantir Technologies (PLTR)

Palantir Technologies leans into the Healthy high growth potential theme through its Foundry, Apollo and AI Platform software, which underpin enterprise and government AI deployments and help explain why analysts expect strong earnings expansion supported by recurring contracts rather than one-off projects.

Palantir runs a dual engine of government analytics and commercial AI software, with about US$3.2b from government clients and roughly US$2.9b from commercial customers, and the stock carries a market value near US$478b.

Palantir Technologies sits at the intersection of government-grade intelligence tools and commercial AI platforms, giving the business a direct link to the screener’s focus on strong expected earnings growth from scalable software and a balance sheet that can support that expansion.

"But the balance sheet tells a different story: the company has zero debt and tons of cash, so that model rewarded it heavily and gave a fair value close to $925."

What could matter most from here is how one underlying pressure on Palantir’s growth story reshapes the balance between rich expectations and future delivery.

That pressure point is exactly where the story gets interesting, and the full narrative for Palantir Technologies shows how Palantir Technologies’ cash, contracts and expectations could be quietly decoupling.
