You're actually misquoting the article you provided. Neither Davis, nor Ryanair or Indigo Partners reps gave any indication (in the article) that they sold on the basis of doubts about future performance. That reason is suggested by supposed 'insiders'. Who are they? In fact, Davis sold only when the Shares topped S$2.25 when all 'insiders' tipped they would max out at S$2.00. Wouldn't you?? As it turns out the Tiger IPO was awarded the most successful IPO in Singapore for the year. But what the hell, lets not allow the facts to spoil a good story.
The fact is that SQ have not provided any funding since start up and have never input a cent to prop up Tiger Australia. The Tiger Group is currently self funding. It was four years before TR was profitable but the group has been in a position to underwrite TT until they achieve critical mass, if not for the GFC and now the recent floods, they might have done so already. But as they say, excuses are like ar*eholes - everybody has one. They now need to find a way to claw back the opportunities lost.
