The consumer index rose 3.5 percent over the 11 months ended in November.

Some economists said they did not think the unchanged consumer index would effect the Fed's monetary policy.

Thus someone who thinks the consumer index will rise might buy a call at a strike price higher than the current level of the index.

If the consumer index comes in at the two-tenths of 1 percent that is expected, then investors will breath easier for the time being.

Over the last year through March, producer prices climbed 1.4 percent while the consumer index rose 1.7 percent.

The consumer index would be up 2.7 percent, down from 5.1 percent in May.

In those days, the consumer index rose at an annual rate of less than 2 percent.

The consumer index increased by seven-tenths of 1 percent in January.

Before rounding, the July rise in the consumer index was 0.2415459, or 2.9 percent at a compounded annual rate.

But even with a slower June added in, the three-month annual rate of increase for the consumer index would still be 4.3 percent.
