Dude the derivatives market has many aspects. Why do you think Lehman Brother's almost collpased the system? They were trading virtually valueless assets for their huge debt obligations to hide teh debts on their quarterly reports. This kept their investors from knowing what was going on and NEW investors were not scared off.
They almost collapsed the system because the derivatives market is a highly leveraged marketplace.
Leverage, through the theory of large numbers, allows risk management and arbitrage algorithms to turn tiny (fraction of a percentage point) profits to be large enough to attract interest. A .02% return is a waste of time, leverage it up 100 times and exit within a half year, and (according to the sharpe ratio) it is a suitable investment and an area where capital should be deployed.
And did you seriously just defend a company making bets that go against their own investors? Are you that morally corrupt or did you just not read what I said?
Would it be wrong for a bookie (that's what a market maker is, FYI) to take a bet from someone else and balance it out with another bet from another person, taking the spread as a profit?
Companies like Goldman Sachs were making bets with other companies that in simplified form was "I'll bet you 300B dollars our investments will drop 200B in the coming weeks". With their gigantic stake in the market, companies like that can and DO cause wild fluctuations in prices. Goldman gets 300B$ and their investors lose. NO PROBLEMS THERE?
No, there are no problems there.
The corporations, hedge funds, and investment banks, that bought these MBS packages were bullish on MB securities. Goldman Sachs, at the time these products were sold, was equally bullish.
It wasn't until later that Goldman switched from net long, to market neutral, then eventually net short in its positions. See my comment above. This is an industry standard, it is not inherently immoral, and it is absolutely not fraudulent. Every bet must be met with a counterparty, and that counterparty could be someone else, or if Goldman saw an opportunity for profit, itself.
Do you not see the conflict of interest or did you just skim over what I said and missed that tid bit?
Would it be a conflict of interest for me to make a bet with you, then make the opposite bet with someone else, hoping to profit regardless of the outcome? No, that is the job of a market marker, broker, and in gambling, a bookie.
