Personal income is the dollar value of income received from all sources by individuals. Personal outlays include consumer purchases of durable and nondurable goods, and services.
Why do Investors Care?
The income and outlays data are another handy way to gauge the strength of the economy and where it is headed. Income gives households the power to spend and/or save. Spending greases the wheels of the economy and keeps it growing. Savings are often invested in the financial markets and can drive up the prices of stocks and bonds. Even if savings simply go into a bank account, part of those funds are typically used by the bank for lending and therefore contribute to economic activity. The only way savings fail to contribute is if they are deposited in the First National Bank of Serta (under the mattress), and not too many people do that anymore.
The consumption (outlays) part of this report is even more directly tied to the economy, which we know usually dictates how the markets perform. Consumer spending accounts for two-thirds of the economy, so if you know what consumers are up to, you´ll have a pretty good handle on where the economy is headed. Needless to say, that´s a big advantage for investors.
