North American stocks continued to struggle in midday trading on Tuesday, even as Alcoa Inc. kicked off the second quarter earnings season on a relatively good note and European bond yields subsided.
At noon, the Dow Jones industrial average was up 22 points or 0.2 per cent, to 12,758.
The broader S&P 500 was down 1 point or 0.1 per cent – putting it on track for its fourth straight decline, or its worst slump since May.
In Canada, the S&P/TSX composite index was down 40 points or 0.3 per cent, to 11,595.

Alcoa, which beat analysts' revenue and operating earnings estimates when it reported its quarterly results on Monday afternoon, was down 3.4 per cent in midday trading; in after hours trading on Monday, the shares had risen about 1 per cent.
The grinding moves in North America stand in contrast to upbeat conditions in Europe, where investors cheered an agreement among finance ministers to extend Spain's deadline for reducing its budget deficit.

The gains follow some relief in the bond market as well, where yields declined for government bonds of some of the more indebted nations.

The yield on Italy's 10-year government bond fell to 5.92 per cent, down 15 basis points. There are 100 basis points in a percentage point.
