The argument prevailing the day weather it is a bubble or justified trend. Some argued it is due to low interest rate and strong cash flow of the tech. Some said when interest rate has no way to move north, the whole market will pop.
We think the market is expensive now. However those techs that leading the charge deliver real profit with good products for the market. Probably when PE hit average 30 times. A bubble will form.
Once again it proves the big bang theory in world economy. No matter up or down but eventually the universe is going to expand more. Also if you have a good idea in tech. You got to goto US as there is the only place will give a good environment for techs.
We think the world markets are expensive except consolidated emerging market. When low interest rate strategy ended and money shift again to emerging markets for historical new high. We will think of a real pull back at that moment and we hope we smart enough to offload some shares.
