According to psychologist Lola Lopes, while fear is indeed a crucial factor driving financial markets, majority of investors don't respond that much to greed but to hope. Lopes indicates that fear, unlike hope, provokes investors to concentrate on unprofitable invests, while hope does the complete opposite. Furthermore, hope and fear are believed to alter the manner in which investors estimate other possibilities. Fear provokes investors to ask: "How bad can it get?", while hope: "How good can it get?". In this case, fear drives investors to enhance security, while hope stimulates investors to emphasise potential.
