Shares in consumer electronics maker V-Tech Holdings rose 6.85 per cent yesterday on healthy turnover as investors judged concerns about deteriorating earnings for the company this year were overdone. V-Tech finished yesterday at $24.15 compared with a low of $21.90 on Monday. The Monday low was 38.13 per cent down from a January 6 high of $35.40. Strong buying was seen through Salomon Smith Barney and Merrill Lynch, suggesting United States funds were increasing stakes in the firm. Turnover has been growing since last Friday. One brokerage yesterday upgraded the stock, saying it had fallen victim to past over-optimistic market expectations. 'The dramatic reversal in its share price performance appears to be overdone,' it said. V-Tech finance managing director William Ho Mook-lam said Lucent, a leading customer, was still placing orders, despite the break-up of its joint venture with electronics giant Philips.
