Market forces rained on the parade of Alibaba Pictures Group Limited ( HKG:1060 ) shareholders today, when the analysts downgraded their forecasts for this year. Revenue estimates were cut sharply as the analysts signalled a weaker outlook - perhaps a sign that investors should temper their expectations as well. At HK$0.51, shares are up 9.7% in the past 7 days. It will be interesting to see if this downgrade motivates investors to start selling their holdings.
