My Bottom Line: Martin Gilbert, Aberdeen Asset Management
Martin Gilbert is chief executive of Aberdeen Asset Management. He says it is very hard to make money from trading shares and the key to investment is to buy shares and hold them - invest in the long-term.
Martin says investors like Warren Buffet and the British businessman Sir John Templeton epitomise everything he admires about investment - buying companies, holding onto them, and waiting for the results to come through.
