Kool-Aid for my man, OptKool-Aid is the 'drink' by which investors lose their money, much like the drink that Jim Jones 'followers' lost their lives. It is prevalent with stocks having great 'stories' but lacking in strong fundamentals. Investors that get 'drunk' on the 'words of the CEO' are the most common of all Kool-aid drinkers. Often though, naive investors will become 'drunk' by other followers of same issue. As the old saying goes, misery loves company, and where 'faith' has caused a group of investors to hold their stock longer than sensibility would dictate (and usually holding a loss), they become known as kool-aid drinkers.
