Ruffer LLP
 Ruffer LLP Investment ManagersFinance Ruffer aims to deliver consistent positive returns – whatever happens in financial markets. The firm actively manages investments, mainly in conventional assets, and operates freely, without restrictive benchmarks. In all they do, they seek to be responsible investors, integrating environmental, social and corporate governance (ESG) issues into their investment process. Ruffer always holds investments in what they call growth and protection. They hold these alongside each other, changing the allocation to each over time. The growth assets are typically equities. The protective assets are usually a combination of conventional and index–linked bonds, currencies, derivatives and exposure to commodities. | Finance |

GVQ Investment Management Ltd.
 GVQ Investment Management Ltd. Investment ManagersFinance GVQIM is an active, medium- to long-term manager which aims to increase the value of the companies in which they invest on a sustainable basis by applying private equity techniques to public markets. The firm believes there are four key drivers of shareholder value creation: earnings growth; re-rating; de-gearing and corporate activity. Where traditional public equity managers have focused predominantly on the former two and private equity practitioners on the latter two, they aim to have a balanced approach. GVQIM works collaboratively with other stakeholders and investee management to avoid hostile activism where possible. | Finance |
