We can follow the projection of the Stock Trader's Almanac going forward. The first chart is mine on which I have been projecting a stock market high in 2013 for a couple of years now. The chart also shows the SOX and VIX in comparison:
Now all we have to do is watch their chart versus the DJIA over the next 15 years. Shouldn't be too tough. All we have to do is stay alive and interested in investing! LOL
Note that the projected loss for the DJIA from its recent high to a bottom of 8000 in 2014 would be slightly in excess of 40%. The rally that would take place after that to challenge former highs before selling off later in this decade will be projected to be almost a 70% gain.
In other words a great trading opportunity before final sell off leads to a lasting bottom and the huge run up starting in around 2017 to 2019.
