Kepler has re-iterated its conviction in the Aberdeen Smaller Companies Income, Henderson Opportunities and River & Mercantile UK Micro Cap trusts as it reviews its portfolio of discount opportunities three months after launch.
The trio of UK equity trusts have seen their discounts widen since February as Brexit uncertainty continues to depress sentiment towards domestic stocks.
However, Kepler's Thomas McMahon said this has opened up "even more of an opportunity" in the former two.
The widening of the Aberdeen and Henderson trusts have purely been a result of rising share prices failing to keep pace with even sharper net asset value rallies.
While River & Mercantile UK Micro Cap's discount has potentially widened because of shareholder dissatisfaction, neither that nor Brexit fears "alter our opinion that the investment thesis remains intact", McMahon said.
Its two closest competitors trade on discounts, around 10% narrower, despite worse performance.
Kepler has also added Schroder Japan Growth to its portfolio, after the discount widened from 10.4% to 12.5% since manager Andrew Rose announced he would stand aside on 1 July. The gap between the trust's discount and the sector average has drifted from 6.1% to 7.9%.
"This could be an interesting entry point," said McMahon.
There will be a period of adjustment as investors get to grips with the new manager Masaki Taketsume, he explained, but he has worked on Schroders' Japanese equity desk for 12 years and had been Rose's deputy since 2014.
Kepler's discount opportunities portfolio is a selection of trusts it believes have the potential to significantly close discounts and, in turn, supercharge investors' returns.
The five others on the list are Menhaden, Tetragon Financial, Baring Emerging Europe, Oakley Capital and Aberdeen Standard Asia Focus.
