I have both (3i and literacy capital) but I had to buy literacy capital on Hargreaves Lansdown.
Literacy capital is an “owned” investment trust. IE there are major shareholders.
At a guess we are talking about close to 45% and they are still buying.
The downside to this is trusts like this often trade on very wide discounts… permanently.
Also the illiquidity will be permanent problem as the managers have said the company will not take on much more businesses.
Instead they will do a capital return rather than reinvesting in another business.
So in my opinion the upside is there particular niche.
In the private equity sector they buy into smaller companies than others do. I suspect in the listed sector they have this niche to themselves.
