The FTSE MIB (also known as the Financial Times Stock Exchange Milano Indice di Borsa) is the premier benchmark stock market index for Italy's national stock exchange, the Borsa Italiana. Think of it as Italy's equivalent of the American S&P 500 or the German DAX. Managed by the FTSE Russell group, the index tracks the performance of the 40 most-traded and most valuable companies listed in Milan. These “blue-chip” stocks are selected based on their size (market capitalization), liquidity (how easily their shares can be bought and sold), and sector representation. The index gives investors a snapshot of the health and sentiment of the Italian corporate landscape. Its movements are closely watched by economists and investors worldwide as a key indicator for one of Europe's largest economies. For anyone interested in European markets, understanding the FTSE MIB is essential.
Like most major global indices, the FTSE MIB is a market-capitalization-weighted index. In simple terms, this means that bigger companies have a bigger impact on the index's value. A 5% jump in the share price of a corporate giant like the energy company Eni will move the index far more than a 5% jump in a smaller constituent. Furthermore, the calculation is adjusted for free-float. This is a crucial detail. It means the index only considers shares that are readily available for public trading on the open market. It excludes large blocks of shares held by governments, founding families, or other corporations (so-called “locked-in” shares). This gives a more accurate picture of the market's day-to-day supply and demand dynamics. The index composition is reviewed quarterly (in March, June, September, and December) to ensure it remains a relevant and accurate reflection of the Italian market, with companies being added or removed as necessary.
The FTSE MIB is famously concentrated in a few key sectors that form the backbone of the Italian economy. An investor looking at the index will quickly notice a heavy presence of:
For a value investing purist, a stock market index is a tool, not a destination. The FTSE MIB is an excellent barometer of market sentiment toward Italy. When the index is soaring, it generally reflects optimism; when it's falling, pessimism prevails. However, a value investor, in the spirit of Benjamin Graham, doesn't buy the market; they buy individual businesses. Blindly buying an Exchange-Traded Fund (ETF) that tracks the FTSE MIB means you buy every company in it—the good, the bad, and the overvalued. This is indexing, not value investing. The real magic happens when you use the index as a starting point.
The best way for a value investor to use the FTSE MIB is as a curated hunting ground for potential opportunities. Here’s how:
