With Macau fever burning ever hotter, more Hong Kong micro-cap stocks have joined the fray this week, announcing gambling and hotel-related ventures in the former Portuguese enclave. The result was another explosive round of share-price gains. Shares in travel agency and hotel operator Wing On Travel (Holdings), which is expected to buy a stake in Kingsway Hotel Macau, surged 17.86 per cent on Tuesday and a further 24.24 per cent on Wednesday before shedding 4.88 per cent to close at 3.9 cents before the share was suspended from trading yesterday. The company said it would soon announce 'the acquisition of a controlling stake in a company that has substantial interest in a hotel'. The move followed news on Wednesday of a deal between mainland property developer Lai Fung Holdings and connected company eSun Holdings to build 30 detached houses on 20,000 square metres of reclaimed land between the Macanese islands of Taipa and Coloane. Lai Fung shares closed 3.36 per cent higher at 24.6 cents yesterday. ESun rose 14.29 per cent to finish at 52 cents. Shares in electronics manufacturer A-Max Holdings surged 51.83 per cent to end at 29 cents before trading was suspended on Wednesday pending the release of an announcement of 'price-sensitive information'. The company was reportedly seeking a minority stake in Macau's New Century Hotel. Mobile handset and components trader Ezcom Holdings is rumoured to be setting up a travel agency in the mainland to organise tours to Macau. The counter gained 9.21 per cent to close at 41.5 cents yesterday. Motor vehicle wholesaler and real estate investor Victory Group climbed 25 per cent to settle at six cents on speculation that it plans to invest in hotels and casinos in Macau. The fervour surrounding Macanese investments is rooted in the notion that tens millions of visitors from the mainland, where gambling is illegal, will pour across the border over the next few years to try their luck at the territory's famed casinos. The speculation has spilled over into the property market. A Midland Realty report said that first-tier residential property prices in Macau had risen 50 per cent this year.
