The value of US buyout group Texas Pacific's stake in J.Crew rose by more than $100m (€79m) in two days after the US retailer went public last week.

Texas Pacific, which raised a record buyout fund this year, bought a 56% stake in J.Crew in 1997 and owns 40% of the public company. The firm did not sell any shares and bought an extra $73.5m of stock during the initial public offering at the issue price.
