I heard that the housing market being low in sales and with the forclousure market crashing, it is affecting investors so much that they are moving money out of equities (stocks) and investing more in safer investments. Thats why the stock market has been down so much in the past week.

How does this happen? I was reading about it, but I didn't really understand. Are investors pulling out their stocks from big lenders? How exactly does it affect the stock market? I need help understanding it in normal terms that make sense.

Please advise, thank you!!
