I like Burford Capital’s business model which is focused on litigation finance. As @Mello says, they don’t have a lot of competition.
So they work with law firms and clients around the world, provide legal finance and advice, and are able to (when they win) seize/recover assets.
Their shares dropped massively recently when some US company shorted them, accusing Burford of manipulating numbers. And then, there’s the accusation of the trading secrets for sex for one of their cases.
Both rumours/accusations could end up being nothing but they have caused the shares to drop to rock bottom prices. Personally, I’m still a little cautious so just keeping an eye on them.
