In this article, we will look at the 10 Fast-Growing Small Cap Stocks to Buy According to Analysts.

​On October 1, Francis Gannon, Co-Chief Investment Officer and Managing Director at Royce Investment Partners, released a report analyzing small-cap performance during the third quarter of 2025. During the third quarter, the highest returns were generated by the smallest stocks, as the Russell 2000 index gained 12.4%, outperforming the 8% gain of the Russell 1000 index. Notably, the micro-caps gained the most as the Russell Micro-cap Index rose 17% during the same time. Gannon attributed this long-overdue outperformance to lower rates and a resilient US economy.

​Gannon highlighted that usually small-cap growth stocks do better than small-cap value stocks in the early part of a market upswing. However, in Q3 2025, the small-cap value stocks actually returned slightly more (12.6%) than small-cap growth stocks (12.2%). Looking at the returns from April 8, the small-cap growth rose 43.2%, outperforming the 35.3% rise of the small-cap value stocks.

​In addition, on November 11, Lauren Romeo, CFA, Portfolio Manager, Principal at Royce Investment Partners, released another report discussing why high-quality small-caps may be poised to reassert leadership in the months. Endorsing the analysis of Gannon, Romeo noted that the initial rebound of the small-caps was led by low-quality/growth stocks. He highlighted that all previous small-cap leadership phases started in a similar fashion, with growth stocks taking the major share in the start, followed by higher-quality/ value companies taking over leadership in the longer term.

​With that, let’s take a look at the 10 Fast-Growing Small Cap Stocks to Buy According to Analysts.
