By Reuters Staff 2 Min Read HONG KONG, Feb 24 (Reuters) - Hong Kong’s home prices snapped three months of decline in January, official data showed on Wednesday, starting 2021 with a modest gain amid a jump in launches and optimism that new vaccines will speed up the economic recovery. Private home prices in one of world’s most expensive markets climbed 0.13% last month, according to the data, compared with a revised 0.3% drop in December. Prices still rose 0.08% in the full year of 2020 amid the coronavirus pandemic, barely extending a run of increases dating back to 2009 when prices were only a third of the current level.
