MILAN, June 25 (Reuters) - Shares in Volkswagen's truck unit Traton were trading on the grey market at around the mid-point of its initial public offering price (IPO) range ahead of its market debut on Friday.
According to German broker Lang & Schwarz, Traton shares have traded at a low of 29.25 euros ($33.3) to a high of 30.95 euros over the past week, although volumes are low.
Shares in the IPO are being offered at 27-33 euros.
Volkswagen aims to raise up to 1.9 billion euros ($2.1 billion) through the IPO, scaling back earlier ambitions to list up to a quarter of the unit by opting to float a 10% stake.
By 1213 GMT on Tuesday, shares in Traton were traded at 29.375 euros. ($1 = 0.8787 euros) (Reporting by Danilo Masoni, editing by Louise Heavens)
