Marcus Stuttard doesn’t like the expression “Wild West.”

The label gets used a lot to describe AIM, the London Stock Exchange’s junior market for growth companies, and the two words provoke a mirthless laugh. “I care more about our market users than I do about people occasionally deciding to throw a bit of mud that’s not well-founded,” says Stuttard, the head of AIM.
