The stock settled 10p higher at a 12-month peak of 133.5p as a wad of hot money chased the underperforming group and Credit Lyonnais said "buy".
According to the Square Mile's dealing rooms, the wave of consolidation sweeping through the logistics industry could soon engulf Salvesen. The company has undergone a painful restructuring in the past few years, spinning off its power-hire business Aggreko, and could be a tasty acquisition for a rival wishing to boost its UK operations.
The boys in the know said Salvesen could attract a bid of about 160p per share, which will value it at about pounds 424m.
The support services giant Hays, up 8.5p at 663.5p, was mooted as a possible bidder. The blue-chip group had a pounds 1.2bn pop at Salvesen about three years ago, but its bid failed to impress the logistics group's shareholders.
An overseas rival could also be attracted to Salvesen's healthy margins and strong management. Former state-owned post offices such as Deutsche Post and TNT Post are expanding through acquisition of parcel businesses, and Salvesen would fit well. Federal Express, the US giant, could also do with a bigger UK presence.
Any potential bidder will have to convince the Salvesen family, which owns around 10 per cent, to sell their domestic silver.

THERE IS some talk that a predator is sniffing around construction group RCO Holdings. The stock built a 4.5p advance to 204p yesterday amid whispers of a bid at up to 350p. The company, which provides support services on construction sites, is involved in several private finance initiative projects to build and operate public buildings. RCO, which last year made pounds 1.8m on sales of pounds 57m, could be attractive for a rival willing to increase its PFI exposure.
