"Global" indices

This category includes all the Comit indices based on all the shares listed on the Italian electronic stock market (MTA).

The Global indices are calculated in real time on the official or reference prices of all the shares listed on the MTA, excluding the Nuovo Mercato. The indices included here are:

Comit Globale
Comit Globale R
Comit Performance
Comit Performance R

Comit Globale (base 31/12/1972 = 100) includes all the shares listed on the MTA and is calculated daily during continuous trading on the basis of the weighted average prices for trading up to that moment (which become "official prices" at market close).

The Comit Global index is broken down into seven main sector indices:

Banking
Finance
Insurance
Telecoms and services
Real estate
Industrial
Transport and leisure

In turn, the industrial sector index is broken down into 9 further subsectors: food and retail; paper and publishing; chemicals and petrochemicals; electrical and electronics; pharmaceutical and biomedical; cement, construction and equipment; metal and steel; textiles, clothing and accessories; auto and tyres.

Comit Globale R (base 31/12/1972 = 100) includes all the shares listed on the MTA and is calculated using reference prices (the weighted average prices of the last 10% of trading) calculated at the close of the trading session.

It is divided into exactly the same sector indices as the Comit Globale (although not into subsectors):

Banking
Finance
Insurance
Telecoms and services
Real estate
Industrial
Transport and leisure

Comit Performance, Comit Performance R

To give a true measure of the profitability of the Italian stock market over time, these four additional indices are calculated.

In general the Comit Globale and Comit Globale R only measure capital gains, and their value therefore falls on payment of ordinary dividends since the reserves incorporated in the shares have been paid out.
The Comit Performance and Comit Performance R indices provide a measure of total yield (dividends plus capital gains), as they include the ordinary dividends distributed.

The latter two indices are therefore particularly useful in measuring stock market gains and losses on medium- to long-term investments such as investment funds, pension funds, insurance companies, etc...

Comit Performance (base 31/12/1972 = 100) includes all the shares listed on the MTA and is calculated daily during continuous trading on the basis of the average weighted prices for trading up to that moment (which become "official prices" at market close).

Comit Performance R (base 31/12/1972 = 100) includes all the shares listed on the MTA and is calculated using reference prices (the weighted average prices of the last 10% of trading) calculated at the close of the trading session.
