The draw of a main market listing is clear. There’s the possibility of benchmark index inclusion, and access to larger, more active investors. In contrast, AIM-listed stocks are declining, independent analysis is rare and the market’s few dedicated investors are starved of new cash. The FTSE AIM All Share index dropped 34% in the five years through 2025, in contrast to a 46% gain in the FTSE All-Share Index, which tracks the main market.
