At the beginning of last year, while the bulls still reigned on global markets, green funds emerged as one of the hottest new instruments.
These funds focused on alternative energy, environmental technologies and water, all of which were part of a growing theme of saving the planet while adding returns to the portfolio.
Now, as some of these funds face closure after significant redemptions, many investors are questioning whether going green is really that wise.
Wealth managers are not so quick to write them off.
Part of the reason these funds are still an important consideration regardless of the oil price, is because awareness of environmental issues is growing among policymakers, the public and industry alike.
'We definitely do not think that green, water and these kinds of funds have dropped off the radar and, in fact, alternative fuel is very much an area where we continue to back the secular theme,' said Eric Sandlund, head of investment solutions in Asia for UBS Wealth Management.
