3 Fast Growing Stocks To Own In October 2026

When the IMF warns that energy costs and record public debt are squeezing global growth, attention shifts to businesses that do not rely on easy money or cheap fuel to expand. That is where fast growing companies with leadership heavily invested in their own shares can appeal. This article highlights 3 such stocks from our screener and explains why insider-backed growth stories may matter now.

The 3 stocks highlighted below are just a small sample, with the full screen surfacing 180 more fast growing, insider-backed businesses with equally compelling narratives that are not covered here.

If you want to identify, filter, and analyze those higher conviction ideas in one place, head straight to the Fast Growing Stocks With High Insider Ownership screener.

Webull (BULL)

Webull is a digital investing platform built around fast, commission free trading in equities, options, and fractional shares. This aligns it closely with the screener’s focus on high growth stock access for engaged retail investors. Brokerage activities generated about US$672 million of revenue, and the business has a market value near US$4.0b.

For investors looking at fast growing platforms that channel retail flow into high growth stocks, Webull offers a clear test case of how product design, AI tools, and management’s outlook can work together to turn trading engagement into a more durable earnings story.

"The successful launch and acceleration of subscription-based offerings such as Webull Premium and paid analytics products are already exceeding targets, combining higher daily trading activity and increased average revenue per user (ARPU) to boost net margins and recurring revenue stability."

What matters next is how one emerging pressure on profitability plays out against those upbeat expectations for growth and user activity.

Those pressure points are exactly where the story gets interesting, so read the full narrative for Webull to see whether rising costs are masking a stronger long term engine.

Estée Lauder Companies (EL)

Estée Lauder Companies runs a broad prestige beauty portfolio across skincare, makeup, fragrance, and hair care, with higher growth coming from its direct-to-consumer and online channels that fit the screener’s growth theme. Skin care brings in about US$7.3b, makeup US$4.3b, fragrance US$2.8b, and hair care US$565 million, with the group valued around US$33.8b.

Estée Lauder Companies gives this screener a large cap example of brand-driven beauty where higher margin, direct digital channels and management’s growth focus are starting to reshape how much profit each dollar of sales can generate.

"Estée Lauder Companies is progressing its multi year Profit Recovery and Growth Plan and One ELC operating model, which has already lifted gross margin by nearly 400 bps between fiscal 2024 and fiscal 2026 and expanded operating margin by 320 bps to 11.2%."

The real swing factor now is whether the next leg of that plan lands cleanly or hits resistance that keeps pressure on earnings quality.

That earnings quality question is exactly where the story turns. The full narrative for Estée Lauder Companies maps out how Estée Lauder Companies’ recovery plan could accelerate or stall from here.

Cerebras Systems (CBRS)

Cerebras Systems builds wafer scale AI compute racks for Generative AI and large model workloads, giving it a direct link to the screener’s focus on fast growing AI infrastructure backed by confident growth expectations. The business generated about US$681 million from semiconductors and has a market value near US$42.1b.

"In late 2025, Cerebras signed a transformative Master Relationship Agreement with OpenAI, contractually bound to procure 750 megawatts of inference capacity through 2028 and backed by a $1.0 billion working capital loan to fund Cerebras's manufacturing scale-up."

What investors will watch closely now is how one emerging pressure on future margins interacts with that contracted AI demand ramp.

That margin question is exactly where the Cerebras story gets interesting, so read the full narrative for Cerebras Systems to see whether contracted demand is masking deeper upside or risk.
