Here Darren Winters provides a jargon busting piece of education around that term that we here all to often but which few bother to explain "GDP"
When you have been investing for a while you soon slip into using the jargon. One such term we often use is GDP or Gross Domestic Product. Here we give a description of this well used indicator and explain the relevance to investors.
Simply put this is the measure of a country’s economic health. In more technical terms it represents an estimate of the total monetary value of all goods and services produced over a specific time period. This includes consumption, government purchases, investments, and the trade balance (exports minus imports). It is used to show the pace a country’s economy is growing or shrinking at. It is considered as the broadest indicator of economic output and growth.
GDP is normally measured on an annual basis although it is also reported on a quarterly basis. Results are published based on three levels of estimate, each becoming more ‘accurate’. For example, in the UK, the first quarter’s results (January, February, March) are initially reported around 4 weeks after the end of the period. This is referred to the 1st estimate. After a total of 8 weeks after the period end, a 2nd estimate is made based on more refined data. This is followed up with a 3rd estimate, which is released after 12 weeks. This report is classed as the final and is referred to as the UK’s Full National Accounts.
In the US they also have three different releases, again each becoming more refined. They are released on the last day of the quarter (Advanced report), followed up by the ‘preliminary report’ a month later with the ‘final report’ a further month later.
In both cases we are more interested in the Real GDP, which is adjusted for inflation.
Probably as an investor you might be asking, ‘why do I need to know about GDP?’ The GDP figures have a relatively high importance to the markets. If a country’s economy is growing at too slow a rate or in fact shrinking, it is not a good environment for the companies operating within it. Thus larger institutional funds may move their money into other markets or countries.
When individual quarterly results are released they can have quite an affect on the markets, even if it is only temporary. As with most economic forecasts the market does not like surprises. Even if you are purely a technical trader it is worth noting when the releases are being made due to the increased volatility during the day.
When countries like China report, they can also have a large impact on a number of sectors as we have witnessed more recently. When there were rumours of a slow down in the GDP, it was immediately suggested that there would be less demand for raw materials and the mining sector took quite a hit.
The table below shows the real GDP for 2004 and forecast for 2005. What is immediately obvious is that all of the forecasts are showing a slowdown in growth.

It is generally considered by economists that a GDP of around 2.5 to 3% is sustainable over the long run. However for developing countries such as China, India, Russia and the African continent, we would expect to see these larger rates of growth.
There are some problems with the GDP measurement, that obviously being it is a lagging indicator as it measures something that has already happened. Plus whilst the headline figure may be good, you need to look at the constituents such as inventories. Increasing inventories may suggest that growth is actually slowing as companies are building stock quicker than they are selling it. GDP forecasts are important in the short term, however as with any news, these figures are often quickly forgotten.
