Up and Down Financial Markets

I just got this in an email that had been forwarded about 5 times, so I am not sure what the source is, but it's interesting anyway.

There have been 14,284 trading days since January 1, 1950. On 33 of those days, the market fell 4% or more. On 35 of those days, the market rallied 4% or more. So there have been 68 moves out of 14,284, showing such days are very rare occurring just 0.4%of the time. 28 of those 68 rare event occurred over the last three months. That's a whopping 41% of all these very rare events since September. No wonder we feel so tired.
