U.S. stocks rose, rebounding from a slump driven by JPMorgan Chase & Co.’s $2 billion trading loss, after an unexpected increase in a gauge of consumer confidence.

Equities rebounded after data showed consumer confidence rose in May to the highest level in four years, indicating falling fuel costs are helping households look beyond a retreat in stocks and weaker employment growth. Earlier declines were led by JPMorgan. The firm’s chief investment office, run by Ina Drew, 55, took flawed positions on synthetic credit securities that remain volatile and may cost an additional $1 billion this quarter or next, Dimon told analysts yesterday.

Nine out of 10 groups in the S&P 500 rose today. Technology companies, which comprise 20 percent of the benchmark measure, added 0.6 percent, led by some of the world’s largest companies. Intel Corp.
