pledged share value

today received my PB broker statement. surprised to find that my pledged shares value has increased 99.7% from the previous month value. Not really sure why the broker suddenly decided to do so, but it does reflect the market value of my Hai-o stock closer. Coincidentally, my latest copy of Shanghai magazine has featured Hai-o in an article, citing it as one very successful business that has tapped onto the information technology to supercharge its traditional business forward. Although it keep me wondering if this means my little beloved stock will start to have more analyst's following and hence attract more institutional investor? My reading on the edge also make me realize that NTPM Teoh is accumulating NTPM stock, despite that Tabung Haji has been cashing out for weeks.

I have also just opened a US trading account. My friend HK shared with me most US banks have Debt equity ratio > 2. Malaysian banks are really much better with none having the ratio > 1. Should i buy into US banks? when it seems imminent that US economy is recovering. Luckily for short future i need not think too much. I don't have sufficiently huge enough spare cash to go into US. While i still have some unutilized cash in Hong Kong, i should probably try to buy HK stock first.
