It's nothing really new. If we look at how things go at stock markets, then it more often than not is a frequent occurrence that people take out loans and mortgages to buy stocks and other financial tools. I have even seen economists and market 'experts' recommend people on TV to borrow money to invest in stocks, and even to get involved in leverage trading.... It's disgusting advice, but there are really dumb people actually doing so. If you invest with borrowed money, you'll more likely than not to end up with major financial problems, and especially so if you take a dive into leverage trading. It's asking for problems....
