I've noticed that everyday there are at least a few announcements that seem to have effect on the market. So which announcements are important and what exactly are they about?
These are the main types of economic data along with when each report is released by the US government:
Gross Domestic Product (GDP)
In case you slept through Econ 101, or just never took it in the first place, the GDP represents the finished goods and services generated by a country during a specific period.
The calculation is split into four different categories: private consumption, government spending, business spending and total net exports. GDP is generally considered to be the most relaible indicator of an economy's health. Economic growth is generally represented by raises in the GDP. The US GDP data is released once a month in the third or fourth quarter of the month.
Inflation data
This shows whether or not prices have increased or decreased over a given period of time. Since there are millions of goods and services within any given economy, what's known as a "basket" of goods and services is used to measure changes in prices. The basket takes common items like milk, bread, gasoline, etc. and measures increases or decreases in their respective prices. Increases indicate inflation, whereas decreases show the opposite. Inflation data in the United States is released as monthly as the Consumer Price Index.
Interest Rates
These are set by the central banks of any given country and are used to control the monetary supply and direct fiscal policy. The Federal Open Market Committee (FOMC) determines the bank rate in the United States and they meet eight different times a year to determine whether to raise, lower or leave the bank rate the same.
Employment Stats
This one is pretty self explanatory- it's the employment statistics for any given country. The U.S. stats are called non-farm payrolls and are released on the first Friday of every month. Generally high employment is good as it signals a strong economy but in some cases could indicate inflation. So it's best to get as much context as you can when looking at the numbers.
Retail Sales
Retail sales reflect consumer spending over a given period. Retail sales are gathered by looking at the sales of selected stores in varying industries. Sales also provide an idea of the strength of the economy and increased spending shows a healthier economy. In the U.S., the retail sales figures are released sometime mid-month.
Durable Goods
These statistics measure the number of goods that are ordered, shipped and unfilled over a given period of time. Durable goods are those with a lifespan over three years and can include products like kitchen appliances, vehicles, etc. These numbers show the amount consumers have spent on longer term goods, and also provide an idea of how the factory sector is doing. In the US this data is released around the 26th each month.
Hope these definitions help you sort through all the data that's being released. :)
