Inter-personal relationships have equal effects on business management and stock investment. We are a social species, yet some executives and investors like to be loners. However, the chances of sustained success improve when we are able to build long-term and trusting relationships with others for mutual benefits. It is generally a multiple rather than a dual matter, though intensity inevitably decreases with the size of a group or a team. Global effects on business and stock investing are special, because bonding with people from other cultures presents special challenges.
