Actually I knew a guy that did that. He took around $22k or so of cash advances from his credit card and put it in a trading account. Then he traded on margin. Put all the money in LU (lucent technology) at around $40 per share or so. This was right as LU was starting its decline. I guess you couldn't call it trading...he only bought that one stock and it just went down.
We mocked him hard and he stopped coming into work once the stock went to the low $30s.
Unless something really happened to him, why would he stop coming to work now that he's ten's of thousand's of $$'s in debt and if he put ALL the money he had into that stock, personally bankrupt? Wouldn't he needed the job more than ever to survive now?
