The market landscape is increasingly controlled by large firms that expand their reach by acquiring smaller competitors - a trend that the Trump administration’s looser regulatory policies will likely intensify. But a handful of under-the-radar players will persist by leaning into their niches.

Spotting these rare opportunities takes time, and we started StockStory to simplify that process. Keeping that in mind, here are three hidden gems that could end up being the next big thing.

Impinj (PI)

Market Cap: $5.47 billion

Founded by Caltech professor Carver Mead and one of his students Chris Diorio, Impinj (NASDAQ: PI) is a maker of radio-frequency identification (RFID) hardware and software.

Why Is PI on Our Radar?

1. Annual revenue growth of 18.2% over the past five years was outstanding, reflecting market share gains this cycle
2. Incremental sales significantly boosted profitability as its annual earnings per share growth of 336% over the last five years outstripped its revenue performance
3. Free cash flow margin increased by 23.2 percentage points over the last five years, giving the company more capital to invest or return to shareholders

Impinj’s stock price of $188.49 implies a valuation ratio of 96.4x forward P/E. Is now the right time to buy? Find out in our full research report, it’s free.

Griffon (GFF)

Market Cap: $3.71 billion

Initially in the defense industry, Griffon (NYSE: GFF) is a now diversified company specializing in home improvement, professional equipment, and building products.

Why Does GFF Stand Out?

1. Operating margin expanded by 8.8 percentage points over the last five years as it scaled and became more efficient
2. Performance over the past five years shows its incremental sales were extremely profitable, as its annual earnings per share growth of 28.8% outpaced its revenue gains
3. Free cash flow margin grew by 13 percentage points over the last five years, giving the company more chips to play with

At $79.68 per share, Griffon trades at 13x forward P/E. Is now a good time to buy? See for yourself in our in-depth research report, it’s free.

WEBTOON (WBTN)

Market Cap: $1.90 billion

Pioneering a vertical-scrolling format optimized for mobile devices, WEBTOON Entertainment (NASDAQ: WBTN) operates a global platform where creators publish serialized web-comics and web-novels that users can read in bite-sized episodes.

Why Do We Love WBTN?

1. Offerings and unique value proposition resonate with customers, as seen in its above-market 7.5% annual sales growth over the last two years
2. Projected revenue growth of 13.6% for the next 12 months is above its two-year trend, pointing to accelerating demand
3. Performance over the past two years shows its incremental sales were extremely profitable, as its annual earnings per share growth of 79.7% outpaced its revenue gains

WEBTOON is trading at $14.45 per share, or 47x forward P/E. Is now the right time to buy? Find out in our full research report, it’s free.
