On the first chart, I performed an analysis that is similar to the one I did comparing the Dow today to its performance during the Great Depression. I graphed the Nikkei from 1970 to 2009. Using the other Y axis, I graphed the Dow from 1988 to 2009. The 0 point on the graph represents the high point of both markets – 1989 for the Nikkei and 2007 for the Dow.
You can see the result. From its high at 0 point to its drop three years later, the Nikkei shed 57% of its value while the Dow has shed 44%. If the Dow was to follow the Nikkei’s lead and drop by 57%, then we could expect it to bottom out at around 5,700 (where the yellow line meets the blue in Year 3).
Is this reasonable? Data from the Nikkei as well as from the Great Depression Comparison seems to show that with severe economic crisis, markets fall by over 50% and often by greater than 60%. In other words, the severity of the crash is proportionate to the level of the run-up. Japan experienced a huge run-up in the 1980s. The US experienced a large run-up before the depression. Both led to a severe crash in the markets. Since all economists seem to agree that we are in the biggest economic crisis since the depression, it’s fair to think that the stock market’s losses will reflect that.
