(Reuters) - JPMorgan Chase & Co's (>> JPMorgan Chase & Co.) commodity market trading risk measure, known as Value-at-Risk (VaR), was steady in the three months through June, the bank said on Thursday, the first Wall Street bank to report earnings.

The bank's VaR indicator was $9 million in the second quarter, unchanged from the prior three months and the same period a year earlier.

The news came as the bank reported a marginally lower second-quarter profit but still beat subdued analyst expectations, helped by loan growth and a tight control on operating expenses.

The VaR is a risk-reward indicator that measures the commodities exposure of Wall Street banks, which typically group commodities revenue under the fixed income category and do not break out the sector.
