The societal value of activist investors

Wall Street Journal columnist Francesco Guerrera speaks to William Ackman, Carl Icahn and other heavyweights and comes to this thoroughly rational conclusion: "Activism investing is just another way to try to beat the market by picking undervalued stocks.

He writes: "If JPMorgan Chase is found to have violated the Foreign Corrupt Practices Act by hiring the children of the elite, then the entire financial services industry is probably in a heap of trouble."

Just how much did Glencore overpay for Xstrata?

From the Financial Times's Lex column, writing on Glencore's massive asset writedown just three months after buying Xstrata: "Well, at least we now know for sure that Glencore overpaid for Xstrata by almost $8bn. The question is whether it overpaid by even more than that." Sure seems like it did.

Bubble indicator of the day

From Bloomberg News: "A five-bedroom house in Las Vegas sold in mid-July for $499,000, double the price it went for three months ago. In Phoenix, a similar house sold this month for $600,000, gaining $273,000 since March." This could turn out ugly again.
