The S&P 500 is trading at 7,731.41 at midday, a steady climb since the open with no significant reversals behind the move.

That rotation matters for investors trying to read the market's mood. A broad S&P gain driven largely by tech implies that participants are comfortable taking on risk, at least for today. If the Dow were leading instead, the story would be more cautious.
