My experience in corporate life is that when a very large company swallows a smallish company, the smallish company seldom does well. This is because the revenues and profits of the smallish company pales in comparison to that of the large company. In other words, management is unlikely to focus on the smallish company unless there is something really special about it.
Budget airlines are like commodity businesses with razor thin margins and I really don't see anything special about Tiger Air. As for oil rates, I think most airlines are rather shielded.... if the price of oil goes up, they just increase the fuel surcharges and vice versa. Hedging is only a short term strategy that is unlikely to result in any long term financial gain, assuming they hedged in the right direction.
As the world economy struggles, I think airline stocks will also continue to struggle.
From my observations eversince I joined pertama forum past one over year, I strongly believe that many readers here have something-in-common like you, i.e. majority of them are not interested to read and digest the lengthy and super boring news updates to form their own views on the stock market. The only uplifting news / posting which interest them most is that, what's the best tips or hot stocks to trade to make some quick intraday profit. (That could be the main reason why the forum has been dead quiet without interesting postings except my news updates and charts postings; occasional postings from the forum owner oldman and intermittent postings from a few regular forumers.) Don't believe me? See the no. of quiet guests below. These are the 24/7 readers of pertama forum and they're also the regular gamblers, whom I've just mentioned.
