Warren Buffett and Carl Icahn might have spent years honing their skills, but new research argues that your genes play a significant part in determining the type of investor you become.
Up to 25 percent of investment decisions are down to genetics, according to economists Henrik Cronqvist and Frank Yu from China Europe International Business School (CEIBS), and Stephan Siegel from the University of Washington.
They conducted a study of 35,000 identical and non-identical twins in Sweden to look at what determines an individual's "investment style" – whether they are value or growth investors. Identical twins, which are genetically identical, were used to find out if any difference in investment style would be due to environmental factors, while the non-identical twins were used as a control.

"What we found is that it is nature and nurture – it's both your genes and your environment that affect how you invest," Cronqvist told CNBC on Friday.
With regards to nature, the economists argue that investing style has a biological basis, with a preference for value versus growth stocks partially ingrained from birth.
'Warren Buffett gene'
"There is such a thing as the 'value gene' - or the Warren Buffett gene – but this a bit of an oversimplification," Cronqvist said. "It's probably not one gene, it's probably a complex set of different genes that are involved."
