The Bottom Line:

Because Internet businesses are highly dynamic, innovation and advances in the tech space mean that new entrants can grow quickly and displace current leaders. Companies can also surge significantly, only to lose steam or fizzle out entirely—a notorious phenomenon of the 2000 dot-com bubble burst. Investors should, therefore, conduct thorough due diligence before investing in Internet-based companies.
