1。你上次的custody的问题：
All securities (including shares) purchased by you are delivered to SCB as custodian and are held by the Bank or our nominee as custodian for and on behalf of you. While you remain the beneficial owner of these securities, at the point of account opening, you have authorised us to exercise all rights accruing or vested in you under the applicable law in relation to the rights of voting in respect of any of the securities held for your account. SCB or our nominee will exercise all rights of voting in respect of any of the securities in such manner as we deem fit. You further agree that we may at our own discretion decide not to exercise any of such voting rights. Please refer to Sections 1.4 and 1.6 of Section 3 (Investment Product Terms) for further information.
简单的说，就是你放弃投票权。

2. 以新加坡来说，commission很多都是0.25-0.3%范围内，区别不大。

3. 以美国来说，当然区别很大啦。直接开美国户口一个风险是股票行如果规模小可能会倒闭。虽然有保险，但处理过程中你动弹不得。所以小心选择，不要只是选便宜的。

4。新加坡有optonexpress和thinkorswim可供选择。

5。不过你如果在新加坡开户，你要过CAR，RWS才能买卖外国股票。
