HONGKONG (January 1): IT IS most unlikely that Hongkong's business community will ever see another year like 1973 - the vast majority of investors are fervently hoping that they do not. It is customary around this time of year to hand out some bouquets and brickbats for the performance of individuals in the financial arena. Few, surely, would contest a laurel being placed on the shoulders of Mr Philip Haddon-Cave, our indefatigable Financial Secretary. 'Flying Philip', fortified with nothing stronger than the occasional whisky and soda, has spent a gruelling 12 months coping with the mind-bending complexities of the world currency situation, the tantrums of the stock exchanges, a bucking and rearing economy and the ghastly arithmetic connected with the mass transit system. He capped the rot a few weeks ago by pushing through, against all odds, a reasonable agreement with the United Kingdom authorities that takes at least a good chunk of the strain off our reserves pinned to the groggy pound.
