** Shares of Italian cable maker Prysmian PRY.MI fall as much as 7.8%
** U.S. President Donald Trump plans to scale back some tariffs on steel and aluminium goods, says Financial Times report citing people familiar with the matter
** Shares on track for worst day in 10 months if losses hold
** Citigroup believes news is a negative read for PRY
** "Should aluminium cable tariffs be eliminated, while keeping commodity tariffs in place, this could advantage foreign competitors in practice, given their access to cheaper raw materials" - Citi
** Adds prospect of copper cable tariffs, which accounts for majority of Prysmian's U.S. industrial and construction (I&C) sales by value, looks more remote
** Sector peers including France's Nexans NEXS.PA and Denmark's NKT NKT.CO also down around 3% to 4%
