Talk of spin-offs generated plenty of excitement yesterday with many stocks expected to launch units becoming hot property. Nikko Securities senior institutional sales manager Kent Rossiter said: 'This is big-time spin-off fever. It seems every one that can be split-up is being spun off.' Cheung Kong, which has announced it will launch its China infrastructure unit soon, made the best advance in the market, rising $1.25 to $56.25. Hutchison Whampoa, which is spinning off satellite operator AsiaSat, climbed $1.10 to $49.70, and civil engineering company Wai Kee, which will launch Road King Infrastructure, rose 12.5 cents to $2.425.
