I've been thinking about money and investments, a process I go through about once every two months or so. Back when I was in high school (early 90s), the tech sector was an obvious winner. I don't think it is now, although apparently not everyone agrees. I'm sure that technology companies still have growth left, but I can't imagine a recurrence of the growth during the tech bubble over the last 12 years.
From my perspective, the driving factor behind the tech boom was the wide-spread adoption of technology solutions by brick and mortar industries. In a period that seems almost over-night, companies adopted e-mail, web services, and networked architectures. This allowed huge growth rates in revenue for tech companies as they fought to keep up with demand. But the situation now is different. Most companies already have some sort of working technology infrastructure. The market for technology products is essentially saturated. To me, it's inconceivable that demand for technology products will continue to grow at the rates we saw in the 90s.
When I briefly studied economics in college, we learned about a product life-cycle: development & innovation, growth production & marketing (supply was less than the market for the product), market saturation point, followed by sustained sales until product death or new development. TVs were the example used in class, as I recall. When the TV was first developed, they faced an introduction period, followed by a huge surge in growth. Any company making TVs could pretty much count on selling them all, because there were lots of people who wanted TVs and didn't own one yet. Now, of course, TVs are a saturated market -- practically everyone in America owns one (or two or three). TVs are still sold, but no one expects to see 20% increases in unit sales, because there's no one to buy that many TVs. TVs have avoided the product death phase by innovating: black & white -> color -> digital -> HDTV. Each of these innovations motivated some segment of the population to replace a TV before it broke, thus increasing the sales of TVs above what you would expect for mere maintenance purposes.
So where does this leave the tech industry? While the market for computers and telecom equipment isn't necessarily saturated, practically everyone I know of that would like to own a computer, already does. Businesses, the other driving force behind computer sales, have already made the huge purchases associated with rolling out a new technology. Now, they are only making purchases for maintence and upgrade reasons.
I'm not entirely sure what (if anything) is poised for 90s style growth this decade. It seems that medical (especially genomics) companies could be poised for dramatic growth if the final break-throughs in areas like cloning and gene therapy are made. Security related sectors may also see a surge, given new concerns over terrorism. But there's nothing so obvious that I'd feel comfortable sinking money into it yet. So, instead, I'm just sticking with an index fund. That way I'm pretty much guaranteed to get a slice of any sector that sky-rockets, and I don't even have to think about it.
