MILAN (Reuters) - Shares in BT Group surged more than 17% at one point on Thursday after its new boss set out a path to more than double free cash flow over the next five years, cheering investors.

The spike put the London-listed telecoms group on track for its biggest one-day gain ever. Traders cited possible short covering behind the outsized move.

Allison Kirkby, who became BT CEO in February, was quoted by the FT as saying: "I always love to squeeze the shorts ... and prove them wrong".

With Thursday's surge, the stock is up 6.4% so far in 2024.

Funds AKO Capital LLP, BlackRock Investment Management, Canada Pension Plan Investment Board and Kintbury Capital LLP hold the biggest short positions in BT, according to regulatory filings.
