With arguably the most sentimental day of the year around the corner – Valentine's Day is on February 14th – investors are being urged to not get too attached to their investments .

Many investors don't take profits at the right time and don't cut 'losers' when they should, according to the head of communications at FC Asset Management , Jason Hollands.

Mr Hollands says behavioural science gives insight into the minds of those with investments.

Like star struck lovers, investors frequently suffer from 'loss aversion' – an unwillingness to crystallise a loss, he explains.

As a result they hold onto investment in the hope that the price will go up to what it was when it was initially bought.

By moving to a new investment however, they could have the opportunity to recoup the loss, Mr Hollands points out.

He adds that a professional multi-manager could help private investors to manage an investment portfolio of funds in a disciplined manner.

A multi-manager will ensure that the overall investment strategy and asset mix remains consistent with the goals of the investment portfolio and will help weed out underperformers through constantly monitoring individual fund holdings, Mr Hollands concludes.
