The collection of big U.S. banks had to be feeling pretty good about themselves. JPMorgan Chase
That's right, I said "Citigroup" and "profit."
But of course, it was destined to be shattered thanks to the SEC and its fraud suit against Goldman Sachs
Goldman suit or not, though, Wall Street is still far from healed. More credit losses could still be on the way and the whole industry is badly in need of reform. And in the midst of all of this, there's something particularly worrisome about the banks' first-quarter earnings reports that overeager investors may have missed.
But first, some background
Goldman Sachs is a perfect example of the evolution of the investment banking industry. Back in 1998, the company generated 40% of its revenue from investment banking advisory services and another 33% from asset management. That made the firm pretty safe and secure, but not too terribly exciting.
Through acquisitions and a general realignment of the company's focus, by 2000 the firm had boosted its equity trading from less than 10% of the business to more than 20%. Stymied by the bursting of the Internet bubble and falling commissions in equity trading, Goldman shifted its focus to fixed income, where it could feast on huge commissions and black box trades by working in areas like asset-backed securities where there were no exchanges and most products were anything but standard.
By 2006, Goldman's fixed income, currency, and commodity (FICC) division was close to 40% of the company's revenue. Investment banking and asset management had been relegated to support roles, now generating just 15% and 17%, respectively, of the company's revenue.
And though I'm focusing on Goldman here, the trend was very similar for other major Wall Street firms. In 2006, trading and principal investments in FICC generated around half of the revenue at Lehman Brothers and Bear Stearns.
The rise and fall of FICC
But how exactly was fixed-income trading able to become such a massive part of Wall Street's revenue? The housing bubble, silly!
Easy credit and the housing mania allowed traders to make big bets on a sure thing (after all, housing prices never go down, right?) and gave pension funds and overseas investors a huge appetite for exotic paper like MBSes, ABSes, and CDOs.
Though it was all very irrational, it made perfect sense that Wall Street was making big money off of it. That is, until it didn't.
As we all know, the turnaround hit like a category five hurricane and the Streetwide feasting on the housing bubble led to a reckoning that cascaded through Wall Street and overseas to companies like UBS
Ready for the scary part?
We're now supposedly on the other side of all of that. Most of the bailouts have been paid back, Citigroup is profitable again, and Ken Lewis has finally been booted from Bank of America.
Yet I wouldn't touch the big banks with Angelo Mozilo's money. Why? Take a good look at the first-quarter reports coming out of Wall Street. FICC trading and investing is absolutely booming. Morgan Stanley
All of these businesses are black boxes so we have no idea what's actually generating all of that revenue. Is it real? Is it in any way sustainable? Is it leaving these companies exposed to more losses? Is it just one big replay of the tragic story we just lived through?
It'd be silly to expect to get real answers to any of these questions. And as long as that's the case, if you're an investor eyeing any of these companies, you need to either get comfortable with making speculative bets, or start looking elsewhere for investment opportunities.
