I don't think so that this fall of -24% indicates any kind of the end of .com and tech bubbles. This types of fall are seen often and they are mostly present in correction mode of the stock trading markets. But it is far better than those 90's tech and .com bubbles as right now the tech companies are really having that kind of earning potential and maturity in the terms of business. This type of falls are often seen when the overall stock valuation is overvalued, then it has to come down to match its correct valuations and i think it will be adjusted soon.
