Actually
this is including this month.
You are also missing this, without which the current drop would look a lot more like the crash in 29, possibly worse. Had the Federal Reserve not propped up all the failing banks they would all have most likely declared bankruptcy within a month. Where do you think the dow would be had that happened?
Here is a list of DJIA companies that would now likely be bankrupt had the government not interviened:BOA,Citigroup,GM,JPMorgan Chase
That is over 10% of the companies in the DJIA that would now be bankrupt, in the span of a few months.
The difference between now and 1929 is not the scale of the drop, but the magnitude of the governments intervention in the market.
