Have you got a current driving licence? <a href=" http://vfg.se/methotrexate-25-mg-tablet-price.pdf#vernon ">methotrexate injection 15mg</a> We care about margin debt for two principal reasons. First, it measures the level of optimism in the market. If you are willing to borrow against your securities you must be fairly confident because you risk being forced to sell them, often at the worst possible time, to meet a margin call. That, of course, is the second reason we care: lots of margin debt means you can have lots of forced selling, allowing downdrafts in the market to take on a life of their own.
