Deutsche Asset Management has re-opened Citywire AA-rated Tim Albrecht’s German equity fund to investors 18 months after it made the move to slow flows into the regional strategy.

The German group announced restriction measures on the DWS Aktien Strategie Deutschland fund after it raced from €1.2 billion ($1.37 billion) to €3 billion ($3.44 billion) over a three month period.

According to company data, it has fallen back to €2.84 billion ($3.26 billion) in assets, which, coupled with improved liquidity conditions in the market, has allowed Deutsche AM to re-open it fully.

The firm has a version of the fund which is the most popular mutual fund among Chile's pension fund. In a recent interview with Albrecht revealed the recent changes he's made to its portfolio.

In a shareholder note, the company said there is especially renewed liquidity in the mid-cap section of the German equity market, which means the fund’s capacity limit now sits well above its current level.

The DWS Aktien Strategie Deutschland fund has been in operation since 1999 with Albrecht taking over from Henning Gebhardt in December 2016. This saw Gebhardt as its new chief investment officer.

On a three-year total return basis, the DWS Aktien Strategie Deutschland fund is the second best-performing out of the 64 dedicated German equity funds in the Citywire database.

Over the period to the end of May 2017, the fund returned 51% against an average manager return of 26.5% over the same timeframe.
