One of the bad side effects of artificially low interest rates is it encourages malinvestment. What works for a company at two or three percent interest probably doesn't at 5% or when you can't get credit at all. Low interest rates encourages management to borrow lots of money to buy stock back and pay dividends when they should be saving for a rainy day.

It is a rainy day for GE.
