If we compare the SP-500 index with an index built from all current US stock exchange shares, it is clear that the SP-500 index with 2014 added about 20% (6,9% per annum), while the index of all stocks has hardly changed. In the picture above is the SP-500 index, bottom index of all stocks.
What that might mean?? The first thing that comes to mind, this is that investors have acquired only the most reliable shares for the last two or three years and got rid of all the rest. Apparently the reason for this is, that the bull market has been going on for a very long time and investor logic suggested that a new economic crisis is likely and, respectively, stock market crash. That's why, if this happens, it is better to sit out in reliable promotions.
The second graph shows that the index of all stocks in 2015 the year fell by more than 20% what, by tradition, considered a bear market. But since the SP-500 did not decrease by this amount, then the bear market was not fixed. This is how simple it is — you just need to maintain the SP-500 index and create the appearance of the success of the American market. And the rest of the shares do not care, let it fall as much as you like. apparently, such a new approach to the manipulation of financial markets.
On the other hand, if it's a bear market, though hidden, has already taken place, then now another long ascent awaits us. The main thing is to have time to buy the right stocks :)
