Similar to Great Depression

3/15/09...I read an article awhile ago which I can't find anymore. The article showed that during the great depression, the market would go down and create a new low, then rally back up almost to the previous low and then go back down and create a new low and would continue doing this.

I looked at charts and it does seem to have done this between 1929-1935. I'm worried that this rally we are having now is following the same pattern and it will go up to a previous low and then crash and create a new low.

Here's another article that compares to the two.
