INVESTORS poured US$10.6 million into Jardine Fleming's (JF) Pacific Smaller Companies Trust on its first day. The fixed offer launch period on units in the fund at US$10.53 will end on June 4. A JF spokesman, noting that the US$10.6 million was a record for a first day of a launch, said the unit trust shop in Jardine House had been very busy. Jardine Fleming Unit Trusts general manager Blair Pickerell said the group had received hundreds of inquiries about the fund and expected interest to continue to be strong. He said the total raised was unprecedented for a Hongkong fund launch. ''Normally you do not get the rush of money coming in until much later in the launch period, probably in the last two or three days,'' he said. It follows the fund management house's successful launch of the eastern smaller companies trust, which invests in smaller firms in the Asia-Pacific, excluding Japan and Australasia. Japan and Australasia is included in the investment area of the new fund. Jardine Fleming Unit Trusts assistant director Betty Ng said: ''Smaller companies have become very popular with investors. ''They are the most entrepreneurial companies in the region and are well positioned to take advantage of rising consumer demand in Asia and development opportunities in China and Indochina.'' The fund has a minimum investment of US$1,000, a front-end charge of five per cent, an annual management fee of 1.5 per cent and a redemption charge of one per cent. In total, the group has US$11 billion under management. There were previous successful launches by JF in 1989 and 1990 when it raised more than $150 million each for funds covering Malaysian and Thailand. In recent months the unit trust industry in Hongkong has stirred into life with a fund launch in fixed interest investments and a new 24-hour free telephone fund information service by Fidelity Investment covering Japan, southern China and Singapore. Different fund management groups have been forging links with banking chains to distribute products to a wider audience, including Hang Seng Bank customers. In the first three months of this year, there were total sales of HK$514.4 million, the second highest since 1989. Total redemptions in the first quarter were HK$448 million, which took the net sales position of the industry to HK$65.7 million. The net sales figure for the period is the third-highest recorded. The highest was achieved in the first quarter of 1991 when net sales were $111.2 million. In the second quarter of that year net sales reached $89 million.
