 We get a couple important reads on the economy this week, starting with the Consumer Price Index, or CPI. It's going to be out on Thursday. It measures what we pay for just about everything month to month and year over year. It'll be followed on Friday by the Producer Price Index, or PPI, which takes a look at those same prices at the wholesale level before they reach consumers. Usually the indices move in tandem. You know, if one goes up, so does the other, but that isn't always the case. At the close on Friday, the markets were all in positive territory.
