The majority (76%) of respondents confirmed that they intend to increase their investments during the first six months of the year.
A tenth (10%) were not sure; while only 14% advised that they had no intention to invest more.
The survey polled 767 people with investable assets in excess of £1m ($1.4m, €1.3m) from countries including the UK, the US, Australia, the United Arab Emirates, Qatar, Hong Kong, South Africa, and Switzerland.
DeVere Group founder and chief executive Nigel Green said: “The results of this poll clearly show high-net-worth individuals now have a strong appetite to use the cash that they have held in reserve to top up and diversify their investment portfolios.
“The survey overwhelmingly demonstrates that they are aware of the opportunities to buy high quality equities at the prices they want to pay. They are seeing more favourable choices to boost their portfolios for the longer-term.”
Green continued: “It is a sound investment strategy to put new cash to use in the market whilst prices are relatively low. Capitalising like this on the attractive long-term performance of stock markets is a time-honoured way that investors can successfully build wealth.
“No-one can predict exactly what the markets will do in the immediate future and it’s too early to say if this is or isn’t the bottom of the market. But our poll suggests that high-net-worth investors believe that it is close to the bottom and that there are major buying opportunities.
“It would appear that many high-net-worth individuals kept their powder dry during 2015, as the markets rose then fell and as we braced ourselves for the first Fed rate hike in almost a decade. But any qualms they might have had last year are now countered by more attractive prices.
“They are moving away from a preservation approach by diversifying their investment portfolios. As shown by decades of financial market data, this is the correct approach to risk management,” he said.
