July 28 (Reuters) -

Property and casualty insurer Cincinnati Financial ( CINF )

reported on Monday that its second-quarter profit more than

doubled, reflecting higher premiums and investment income.

The results reflect the stability of insurance firms, even

as trade tensions disrupt other businesses. As consumers and

companies grow accustomed to economic uncertainty, spending on

policies has remained steady.

Earned premiums rose 15% to $2.48 billion, the Fairfield,

Ohio-based company said.

Investment income jumped 18% to $285 million, driven by

higher interest payments from its bond portfolio.

The company reported a profit of $685 million, or $4.34 per

share, for the three months ended June 30, compared with $312

million, or $1.98 per share, a year earlier.

Its shares have risen nearly 4% so far this year as of

Friday's close, compared with a nearly 2.3% gain in the S&P 500

insurance index.

Earlier this month, industry bellwether Travelers Companies ( TRV )

reported higher profits due to stronger underwriting and

investment returns.
