NEW YORK (TheStreet) -- In today's post we are sharing a very special chart.
It shows a complete history of every bull and bear market since the early 1920s.
There's a huge amount of perspective and history to take away from this chart. Foremost, there have been 9 huge bull markets over the last 100 years and 8 notable bear markets. If you think the current bull market is unsustainable, you should first know that it pales in comparison to what has transpired in the past. Throughout the 1940s and 1950s the market climbed more than 935%. In the 1980s and 1990s the market climbed 816% over 153 months.
If you're a market aficionado then this is the kind of chart that you will want to bookmark, print out, or hang on your wall. It's an incredibly powerful way to gauge and compare bull and bear markets:
