Depends on your investment strategy. Fads are nearly impossible to predict. So you have $100,000 to invest and this guy comes up to you with pet rocks. Another guy with toilets that sing. Another guy with shoes that play music. Who do you give the money to? Any of these guys? Just because fads exist, doesn't mean bad ideas don't. Banking on the pet rock was a huge gamble for someone and it somehow worked out. Fad toys must have 1 out of 100,000 success rate, if that.
