Cucinelli could claim promotion to Italy's FTSE MIB index

MILAN (Reuters) - Fashion group Brunello Cucinelli could claim a spot in the FTSE MIB index of leading Italian shares at the expense of energy group ERG in a review at the end of the month, according to two traders.

The index of the top 40 shares reflects market capitalisation and liquidity. Cucinelli has risen 18% this year for a valuation of some 5.5 billion euros ($6.1 billion).

Best known for its cashmere clothing, Cucinelli said last month that its sales had risen by a third in the first three months of the year. It has also been boosted by the general buzz around luxury goods stocks, the traders noted.

ERG shares have by contrast slipped this year and the company is worth only around 4.3 billion euros.

There is one more hurdle to clear to claim inclusion in the index as the newcomer has to rank 36th or above in terms of valuation. Cucinelli is currently vying with truck and bus maker Iveco for that spot ahead of the May 31 review.

The index changes take effect from June 19.
