This can’t end badly, can it?

For the second day this week, stocks posted new two-year highs as a dearth of significant earnings reports, economic data – and the amount of shares being traded – has led bullish momentum to continue to win out over most other considerations.

The Dow Jones Industrial Average climbed 72 points to 12,233, the Nasdaq rose 13 points to 2797 and the S&P 500 tacked on 6 points to 1325.

Despite the lack of trading volume, it was again the key financial sector that helped provide the fuel for another rally. The Financial Select Sector SPDR (NYSE:XLF) rose 0.7% to $16.97, and at one point touched $17 for the first time since last April. Shares of Wells Fargo (NYSE:WFC) did their part, climbing 2.3% to $34.10.

Despite the eventual impact on mortgage rates to come from the steady selloff in bonds – the 10-year note’s yield climbed to 3.73%, its highest level since late April – it was a strong day for housing-related stocks, including mortgate financers and homebuilders.

KB Home (NYSE:KBH), Toll Brothers (NYSE:TOL) and Lennar (NYSE:LEN) all finished more than 4% higher.

Precious metals and related mining stocks pushed higher, with silver prices climbing more than 3% to $30.27 an ounce – its best levels in more than a month. Gold tacked on 1.2% to finish at $1,364 an ounce, and at one point reached its highest level in two weeks.

Other commodities were mixed to lower. Despite a volatile session, oil finished just slightly lower at $87.01 a barrel. Soft commodities were the worst performers, with sugar selling off more than 4%.

In equities, oil-related stocks fared less well, with equipment and services stocks falling as a group.

With volume continuing to drag this week amid mostly b-list earnings reports and little or no economic data, the rally in stocks looks healthy until sellers are otherwise provoked to step in.
