Get excited about the next "new thing", and then load up on companies who are the early entrants for that theme. This is a trap because it appeals to the common sense of most people. Yet there is little evidence that it works, or that it is consistent with the nurturing of an investor's healthy mentality. The public doesn't know this, but the "promoters" do, and they are ready to exploit you - a person - even as they are telling you to exploit an "opportunity." (Most of us were taught that it is good to exploit opportunities, but it is wrong to exploit people. Ponder.) Think of the number of "new thing" companies that were born into the tech bubble. A few did well, most did not, and many went bankrupt. Think of biotech, where the next "hot drug" is often supported by very appealing hype. But whom do you know who got rich? When you start hearing people say things like, "This is really going to be big", there is an excellent possibility that they are hoping to drive prices up for their own benefit, rather than to help you find nuggets of gold. This strategy is like many others, which are dependant on investors getting caught up in "the story." This is a mistake. The story must be the result of powerful economic fundamentals, not the other way around...
