There is no denying that the stock market has been on an amazing run. However, the uptrend on the NASDAQ 100 (QQQ) broke this past Monday and no one is talking about it. Just take a look at the stock chart below. You can clearly see that as of Monday, the NASDAQ 100 broke below the sharp upsloping trend line. This makes the market extremely vulnerable to a pull back and I am in the camp that it happens. Investors should be in cash or short the market based on this trend line break.
