HATERS of junk mail will be pleased to learn that after 10 years or more of discussion, a slot in Legco's programme has been allocated for a Data Protection Act in 1995. This will cover a whole range of issues and it will be interesting to see the effect it has on companies like Datatrade Ltd, which this week wrote to Ambrose Travel offering dozens of mailing lists at various prices. Among those on offer were ''yuppies'', whose names cost 80 cents each. The same price holds for smokers, expatriates, millionaires and ''style leaders''. Incidentally, they've got a list of 29,596 style leaders, which must say something. They have 54,108 on their list entitled ''potential emigrants'', so they clearly can't claim to have complete coverage. That figure seems too low by a factor of about 100. More entertaining are the club and association lists, which include the Hong Kong Tourist Association, the Hong Kong Society of Accountants, the Indian Chamber of Commerce, and the Hong Kong Institute of Personnel Management. It's entertaining because not all the bodies on the list have given approval for their names to be used. In fact, both the HKSA and the HKTA took the news rather badly, with the latter describing it as ''highly unethical''. Quite a few of the lists, according to Datatrade's Louisa Wu, come from published directories. For instance, by law, all accountants must join the HKSA, whose yearbook circulation is supposed to be restricted to other accountants. However, Datatrade managed to get one from a friendly accountant and typed the contents into its computer. In Europe, where data-protection legislation is the norm, members of these lists could take steps to protect themselves. Lists come from strange places, sometimes. One person we spoke to on Friday keeps getting junk mail at their flat bearing the name of a friend. Strange thing is that the friend has only once handed out this address - to the Immigration Department. Not kosher AND what is to be made of Datatrade's offer to sell a list of 322 ''Jewish community members'' for about $260? - the same rate as yuppies but less than frequent travellers or active hire-purchase consumers. There are a couple of clubs among the Jewish community, and maybe they've got the membership list of one of them. Another possibility: in the Jewish religion, the Book of Life is supposed to keep a record of the good and bad deeds done during each day. Maybe Datatrade have managed to get a photocopy of the Hong Kong pages. Under Covered ONE person with an unusual perspective on the market's recent ride is tycoon Chen Den-hwa. He's the Shanghai-born executive running Nan Fung Textiles who gained fame and the rather unlikely nickname of ''Mr Covered Warrant'' after issuing more than a dozen covered warrants on blue-chip stocks in 1991 and 1992, secured by the huge pile of Hong Kong shares he's got sitting in a bank vault. He effectively placed a bet on the market, making a profit of 20 to 25 per cent no matter what happened, but missing the chance for big profits if his shares went through the roof. His last issue was supposed to be on China Light and Power (CLP), but was aborted on December 2, 1992, when South China Capital claimed force majeure during the crash, which is variously described as the Patten Crash or Lu Ping Crash, whichever you prefer. Had the issue gone ahead, Mr Covered Warrant - is he known as ''Covered'' among close friends? - would have collected warrant fees of $72 million, less expenses. However, because the deal didn't go through, he has in theory collected the full gain on a holding of 10 million CLP shares - about $140 million as of Friday. For the dozen deals that did go through, however, the equation is reversed and it's the ordinary punters who are the winners. So far. Scoop poop THE naughty-books business is rather limp these days. Scoop, one of the slickest pornographic magazines in Hong Kong, will be shut forever if a buyer isn't found. The publisher of Scoop, which is officially classed as obscene, is a woman. And even though the text is all in Chinese, she's a Westerner, Christine Brendle, who bemoaned drooping sales across the whole pornographic-magazine industry. Overheads for these operations are substantial: not only has Scoop got photographers, a designer and other staff needed by all magazines, it has to employ a ''humidity controller'' and two ''posture advisers''. Next month's issue will be an extra-enlarged affair on sale for several months. It will also be the climactic issue unless some would-be pornographer turns up, cash in hand. Christine says the magazine was bought as part of a much wider deal by a large publishing house, which she admits is rather embarrassed about ending up running a magazine of this type. She refuses to name the group, and it's not named in the pages of Scoop. However, she seems to work from the office of Hachette, the French publishing giant. Lost cause SINGAPORE Airlines has a computerised phone information line which gives 24-hour flight information. Late on Friday, someone with a loved one on Singapore Airlines flight SQ002 was using it, and duly entered ''2'' when they were asked to key in the flight number. ''Sorry, this flight cannot be found,'' said the line. In fact, they should have typed ''002''. But perhaps SIA could have chosen a somewhat less ambiguous phrase. High-pitched WHAT'S at the very, very top of the 78-storey Central Plaza? Well, it's an observation lounge with a few leather sofas, two telescopes, a couple of phones and some steps down to toilets. The view, frankly, is stunning, but clearly not stunning enough for some. There's also a big laser-disc karaoke set. Breakdown SOME readers have challenged the arithmetic in last week's item about the old Chinese bonds often found framed in offices. The reasoning was that the most common Chinese bond on sale in Hong Kong is probably the Gold Reorganisation Bond issued in 1913 for GBP25 (about HK$287), and which now trades on the Christmas Present market in framed form for about $780, or nearly GBP70. This is a compound rate of 1.2 per cent a year. The rate on an ordinary savings account is usually 1.5 per cent, but on sums less than $1,000 it drops to 0.25 per cent for some banks. Therefore, even though the bonds are in default, they have still proved a better investment than putting the cash into a Hong Kong savings account.
