The Index includes account inventory ratios, machinery orders, stock prices and other leading economic indicators. As the aggregate of many leading indices the Leading Economic Index provides a forecast of the future state of the domestic economy and is thought to predict activity that will occur 6-9 months after the reporting period.

The index operates on a 1-100 scale, where a value lower than 50 means that most indictors are negative and a value higher than 50 means most indicators are positive. In both cases a greater distance from the midpoint (50) means that the indicators are more strongly positive or negative.

Consumer confidence is a measure of popular sentiment concerning the Eurozone economy. The figure is derived from a survey that asks thousands of consumers about personal expenditure patterns and inflationary expectations. In general, rising consumer confidence precedes increased consumer spending, which drives both economic growth and inflation. Even though t he Italian economy is heavily driven by its export sector, domestic consumer confidence is an important gauge of overall economic activity and future inflationary pressures.

A headline figure above 50 shows positive consumer sentiment, while a number below 50 shows negative consumer sentiment; the greater the distance, the stronger the sentiment.

The actual inventories of crude oil, gasoline, and distillate, such as jet fuel, as reported on a weekly basis. The numbers are watched closely by the energy markets, and if the results differ greatly from the expected inventory levels, the market can react strongly. The inventory data can be skewed by holidays and seasonal factors. Weekly data can be unreliable and should be viewed as a part of longer-term trends, so a four-week moving average may be more useful.

A country's trade balance reflects the difference between exports and imports of goods and services. The trade balance is one of the biggest components of the Balance of Payment, giving valuable insight into pressures on country's currency.

Surpluses and Deficits
A positive Trade Balance (surplus) indicates that exports are greater than imports. When imports exceed exports, the country experiences a trade deficit. Because foreign goods are usually purchased using foreign currency, trade deficits usually reflect currency leaking out of the country. Such currency outflows may lead to a natural depreciation unless countered by comparable capital inflows (inflows in the form of investments, FDI - where foreigners investing in local equity, bond or real estates markets). At a bare minimum, deficits fundamentally weigh down the value of the currency.

Ramifications of Trade Balance on Markets
There are a number of factors that work to diminish the market impact of Trade Balance upon immediate release. The report is not very timely, coming some time after the reporting period. Developments in many of the figure's components are also typically anticipated well beforehand. Lastly, since the report reflects data for a specific reporting month or quarter, any significant changes in the Trade Balance should plausibly have already been felt during that period - and not during the release of data.

However, because of the overall significance of Trade Balance data in forecasting trends in the Forex Market, the release has historically been one of the most important reports out of the any country.
