# *rasberries*
x=some state of the stock market ie it's value
t=time
W=wiener process, some random noise fluctation
c=jolly large positive constant
s= small noise constant

it doesn't reach zero it will sortof fluctuate around zero.
Disclaimer: this doesn't actually describe the stock market. I just made it up.
