3 Fast Growing Stocks With Earnings Growth Up To 120%

Investors just watched a $3.2b-plus sell off hit AI related stocks after Wall Street’s heavy bet on artificial intelligence ran into election driven doubts about future spending. When growth stories suddenly look shakier, businesses with rapid expansion potential and leaders who own big stakes can feel more compelling. This article looks at three such fast growing, insider backed stocks from our screener that some investors are watching closely now.

The three stocks highlighted here offer a compelling starting point if you want exposure to fast growing businesses where insiders and analysts share an optimistic outlook. However, if you want the absolute best, these 376 high growth high conviction stocks are the cream of the crop.

Sansan (TSE:4443)

Overview: Sansan is a Tokyo based software provider whose core cloud platform lets businesses share contact and meeting data to support sales growth.

Operations: Sansan generated ¥48,865 million from its Sansan and Bill One segment, ¥7,143 million from Eight, and ¥446 million from Others, all in Japan.

Market Cap: ¥259.8 billion

Sansan ties neatly into the screener theme because its contact and invoice cloud tools are built to help clients lift sales and efficiency. Management is guiding for higher net sales and profit through to FY2027 while still paying dividends. The real swing factor is how profit margins respond if one unseen pressure shifts as the platform scales.

If that margin swing matters to you, start with the DCF valuation analysis for Sansan to see how different scaling outcomes could reshape Sansan’s upside profile.

Micronics Japan (TSE:6871)

Overview: Micronics Japan develops and sells semiconductor test equipment such as probe cards, wafer probers and test sockets, plus display and body measuring gear.

Operations: Micronics Japan generated ¥84,868 million from its Probe Card Business and ¥1,391 million from TE Business, primarily across Asian semiconductor hubs.

Market Cap: ¥336.2 billion

Micronics Japan is directly exposed to semiconductor capital spending, with earnings reported up 89.4% last year and management lifting guidance as probe card demand linked to generative AI increases. That combination of rapid expansion, high insider ownership and index inclusion may appeal to patient investors, depending on how one unresolved cash flow strain related to the higher dividend and capital expenditure levels develops.

That cash flow strain question makes 2 key rewards and 2 important warning signs (1 is major!) a useful next step, especially if you want to see what could stall or accelerate Micronics Japan from this point forward.

Cerebras Systems (CBRS)

Overview: Cerebras Systems builds wafer scale AI chips and rack based systems that power high intensity inference and Generative AI workloads for large customers.

Operations: Cerebras generated US$680.673 million from semiconductors, mainly across EMEA at US$443.509 million and the United States at US$236.618 million.

Market Cap: US$19.41 billion

Cerebras Systems fits the screener because its wafer scale hardware and cloud ready racks are built directly for AI workloads that management and analysts both expect to expand.

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

What happens to Cerebras Systems from here depends on how effectively the company can translate that demand into sustainable profitability.
