A. Many people think the current bull market is overextended because from the low of March 2009 to now, it's more than 7 years. Such a long bull market is highly unusual, therefore, the conclusion is that a correction may be inevitable.
However, the above view could be wrong - a bull market could be measured from the time the market broke above the prior bear market trading range and making new highs. If this is the case, the current bull market won't start from the March 2009 low but from the breakout to new highs in April 2013, this means the current market is not extended at all.
