Bank Of England's Mark Carney On The Sunday Times. "Bank of England Governor Mark Carney said officials may raise the key interest rate before workers' pay increases, according to a Sunday Times interview," wrote Bloomberg's Jennifer Ryan. "'We have to have the confidence that prospective real wages are going to be growing sustainably'" before raising borrowing costs, he said.

Nobel-Prize Winner Warns Of Mood Swings. "The United States stock market looks very expensive right now," said Robert Shiller in The New York Times. "The CAPE ratio, a stock-price measure I helped develop - is hovering at a worrisome level...nothing I've come up with is a slam-dunk explanation for the continuing high level of valuations. I suspect that the real answers lie largely in the realm of sociology and social psychology - in phenomena like irrational exuberance, which, eventually, has always faded before. If the mood changes again, stock market investments may disappoint us."

$50 Billion Man Is Bullish. In a new interview with Barron's, Federated Investors' Stephen Auth says the S&P 500 could hit 2,500 in the next 18 months to two years.

"At the same time, earnings are expanding, and that's a recipe for another leg up in the market."

US Housing Market Check. The NAHB's Housing Market Index will be published at 10:00 a.m. ET. Economists estimate this index of homebuilder confidence was unchanged at 53 in August.

Swiss Bank Had A Hand In Portugese Bank Downfall. "Credit Suisse Group AG helped sell billions of dollars of securities that ultimately played a role in toppling Portugal's second-largest bank," reported the WSJ's Patricia Kowsmann, Margot Patrick and David Enrich. "The Swiss bank was responsible for putting together securities that were issued by offshore investment vehicles and then sold to retail customers of Portugal's Banco Espírito Santo SA. Many customers didn't realize that these vehicles were loaded with debt issued by various Espírito Santo companies and apparently served as a mechanism to finance the family-controlled empire, according to corporate filings and people familiar with Portugal's investigation into the Espírito Santo affair. It is unclear what, if any, direct role Credit Suisse had in selling the securities to bank customers. "

Inversion Are Just Hype. "Establishing a tax domicile abroad to avoid U.S. taxes is a hot strategy in corporate America, but many companies that have done such "inversion" deals have failed to produce above-average returns for investors, a Reuters analysis has found," writes Reuters' Kevin Drawbaugh. "Looking back three decades at 52 completed transactions, the review showed 19 of the companies have subsequently outperformed the Standard & Poor's 500 index, while 19 have underperformed. Another 10 have been bought by rivals, three have gone out of business and one has reincorporated back in the United States."
