OXFORD-BASED ethical investment platform Ethex expects about 100 people to attend its annual gathering on June 8.

The firm’s chief executive Lisa Ashford said of the day-long, free event: “It’s a chance for all of our investors to learn about positive investment.”

This will be the not-for-profit organisation’s second annual gathering – the first was held in Oxford last year.

“We decided to do it in Bristol because it is the European green capital in 2015,” Miss Ashford said.

She described the day as the chance for existing investors and those interested in ethical investing to learn about whether “personal action can transform the finance sector”, and how they can “take control” of their own finances.

There are about 16 speakers at the event, which will be held from 10am to 4pm at The Station.

Keynote speakers include: Matthew Clayton, chief executive of Triodos Renewables, which Miss Ashford describes as a “pioneer” of “green finance” in the UK; and Sue Ralphs, managing director of the Ethical Property Company, which is based in Oxford.

There will also be a number of workshops, with titles such as: do ethical funds have a positive impact? One workshop is a role-play called The Positive Money Game, in which businesses pitch for money and investors make decisions based on ethical considerations.

Ethex, which is based in Cowley Road, has so far raised about £13.5 million to support 28 businesses and organisations since it launched in 2013. It acts as a market maker and an exchange through its website, which connects investors with equity, bonds and savings products that Ethex has screened.
