博纳打开门加税,转移财政悬崖会谈
Reuters Reuters - 9小时前

知情人士透露奥巴马和博纳谈判,博纳提出延长低税率为大家谁也赚不到100万美元,
上面说的工资和价格将上升。奥巴马希望该阈值设置为25万美元。
根据现行法律,35%的最高税率定为1月1日届满,并会自动去到39.6% - 它是在克林

博纳也增加了他的身影1万亿美元的总收入相比,奥巴马的1.4万亿美元的数字。 10年

[个人浅见,请慎重参考]
本人12月10号发了看熊帖。观点不变。
本人不猜点数。
对牛市熊市的定义如下:
牛市:10%的人赚钱
熊市: <5%的人赚钱
加息,能源板块,人民币贬值这些因素会导致非内部驱动的脆弱市场环境。
市场上基本机会很少了。
一旦SPY跌破200天线的0.5%或者1%,无论什么threshold,
那就撤吧。无论分批撤还是一次撤都可以,看个人技术了。
btw:
1.熊市不是不会涨,历史上熊市有多多次大波涨。但那都是抓不住的熊套。
2.有一点我觉得要注意:撤之前先定好再进来的计划和参数,threshold,signal等等。

来自主题: Australia版 - 关于退税一问
总的来说,你肯定可以退回来不少税,但不到15%(30%-15%)
首先你的所谓30%档只是说你超过那个第2个threshold的部分是30%,0-6000部分是不交
税的,第1个th部分是15%,所以实际扣税大概是25%还低,不信你看下每个周期实际纳税和
应得工资的比例(周期长短也略有不同)
第2个因素是你是否刚来澳大利亚3个月,如果是这样,你的threshold比全年属于'澳大利
亚人'的人要低,比如只有0-1500部分是不交税,超过就要交,所以你的实际税率比正常的
要高(因为th比正常低,更可能适用高税率)
不管怎样,理论上,如果一年当中只有部分时段工作的,退税的时候都能拿些回来,除非是

Fundamentally, no matter how smart a guy is, his two priorities are always "
Money" and "Women". Sport is a job and more importantly, a tool of making
money. At the end of the day, spirituality and loyalty are switched on only
when the tool provides enough money. A threshold in that guy's mind defines
what "enough money" represents. Spirituality and Loyalty will be fulfilled
