Yes, that is right. But, 100 bucks is 100 bucks and I am also curious about the commissions here in Thailand.
I have a couple of pink stocks, Stocks I bought out of the US, and I cannot remember the commission fees. When my dividends come in they are taxed at 10 percent, and a commission fee is also applied, each time the dividend is paid.
Personally I am getting out of one. But, another in Mexico is a real winner for me. So, I put up with the fees..
I personally look at the fees, this is just a blatant rip off IMHO. So personally I would never purchase stocks here.
