It is evident that the highly valued stocks always corrects itself. It doesn't matter whether it is in a booming industry or a company with solid fundamentals, once it reaches high valuation, it will someday somehow corrects itself. By somehow I meant that the usual occurance in stock market. The news, people's psychology, candlestick formation, poor financial results, corporate mismanagement, lawsuits and price action. It is not necessary that any of this should contribute to the fall. But one thing for sure is that, once overvalued, it always corrects.
