One of the ultimate fads, in my view, is Facebook (FB - Get Report). Millions of teenagers would no doubt disagree with that assessment. But I am personally growing a bit weary of the product itself, and I suspect that there are many others like me. I'm tired of seeing what little Jimmy accomplished today, or what Linda Lou has posted as the picture of the day.
I'm not taking away from the innovation, or the brilliance of the idea. I just don't see the staying power. Something else, some other social networking phenomenon will emerge, and Facebook will be yesterday's news.
Fads are fun. They can make life a little more interesting, and perhaps a bit easier for a time. But they wear off, and as an investor, I don't want to be left holding the bag. Innovative ideas or companies don't necessarily translate into great stocks, especially when valuations are out of whack, and expectations are sky-high.
If I'm wrong, and any of the above stocks have staying power and their valuations become cheap, there's always a possibility they might hit my radar in the future.After all, I never thought I'd own eBay (EBAY - Get Report), but once the company passed through its high-multiple/high-expectation phase and then continued to deliver 20%-plus net margins while maintaining an excellent balance sheet, I took a position. Of course, it was trading at 8 times forward earnings and was long past fad status. At the time of publication, Heller had no positions in stocks mentioned.
