In its survey of 311 clients worldwide with assets of more than £1m, 53% reported being bullish about the investment outlook for the next 12 months.
The last time confidence levels were beyond this mark was back in March 2010, when 55% of respondents were feeling bullish.
In 2012, 49% of high-net-worth investors reported they felt optimistic for the forthcoming 12 months. 44% said the same in 2011.
Nigel Green, chief executive of deVere Group, said the optimistic attitude is a reflection of the gradual recovery of the global economy.
“The upbeat sentiment is, I suspect, influenced by the eurozone being seen to be taking positive steps to tackle its crisis, the fact that the US didn’t fall over the fiscal cliff, because China has avoided an economic hard landing, and because central banks are claiming to be going all-out to stabilise their respective economies, among other factors, which have removed some of the lingering uncertainty.”
