"Goldman was the only major Wall Street firm to safely exit the subprime mortgage market. however, that Goldman sold off more than $40 billion in securities backed by over 200,000 risky home loans in 2006 and 2007 without telling investors of its secret bets on a sharp housing downturn, prompting some experts to question whether it had crossed legal lines."
Now for some definitions
Short Selling: selling a financial instrument without actually owning it. The purpose is to drive down the price. It is a way to manipulate the market and is illegal under SEC rules. Some people claim it's a benign practice but used over and over to artificially drive the price of a financial instrument down can be destructive. Again this is the process of selling something YOU DON'T ACTUALLY POSSESS. Kind of fuct.
Hedging: Off setting your exposure in one market but taking an opposite position in another market. This is what Goldman is accused of doing. By helping to create and promote the credit default swaps that became the toxic assets key to the meltdown and the betting that those very securities would lose value they hedged and won big time. Additionally, they received back 100¢ on every dollar they invested in other toxic assets, because of the AIG bailout.
Now they whole demonic financial system is trying to demonize Obama as anti-capitalist, anti-market, and anti-investment. They (anyone who doesn't share my views) sucker punched Obama on healthcare will they do in again on finance?
