如果cash flow是正的,那么基本可以搞。
cash flow = gross rents - maintenance - property management commision -
Vancancy Allowance - insurance - property tax - mortgage - PMI (if LTV > 80%)
bottomline 就是cash flow >= 0
这是做投资房的第一个要素要参考的,决定了你入场的一瞬间是就能有利润
第二个要素就是appreciation,在保证了cash flow为正的情况下,可以去追求高
appreciation的地区的房子。但是appreciation 通常和 cash flow是负相关,这个自
己要做一个取舍,看自己的投资风格

中国经济增长放缓引发了外界对其金融系统健康状况的担忧。在长期的繁荣后,中国内

之间还有一个非常重要的区别,这个区别可以让中国免于金融危机,但也会让一些根本

在亚洲金融危机中,韩国、泰国和印尼受到的打击尤其严重,其次是马来西亚。尽管这

在这三个国家的例子中,对效率低下的企业的大规模过度投资都持续了相当长的时间。
在韩国,过度投资主要发生在制造业,当时,韩国的财团竞相通过借贷扩大自己的帝国

奥义书在印度宗教与哲学的发展过程中有重大意义。在奥义书产生之前,吠陀时期的雅
利安人崇拜自然神;梵书则大多是形式主义的祭祀手册。奥义书最早集中精力讨论宇宙
的终极真理。奥义书中两个最重要的概念是「我」和「梵」。奥义书用各种奇妙的比喻
(很多在现代人看来是不可理解的)来说明,梵就是一切,也就是最高存在;人类的我
(个体灵魂)来自宇宙的我,即梵(宇宙灵魂)。
总之,宇宙就是梵,梵就是我;「梵我同一」这个最高真理就是奥义书主要宣扬的观点。
在奥义书的思想基础上产生了吠檀多派,后来直接影响到印度教大改革者商羯罗。
另一个由奥义书系统搭建起来的重要观念是轮回业报。

高亮度蓝色发光二极管之父:中村修二
20世纪90年代中期使得超过人类身高的超大屏幕全彩显示器成为可能、2000年前后
又为手机屏幕彩色化做出贡献的,就是高亮度蓝色发光二极管。蓝色发光二极管技术还
成为了开发蓝色激光器的基础,其实用化使得录制高清节目的蓝光成为现实。高亮度蓝
色LED通过与红色和绿色LED组合便可制造出各种颜色,接踵而来的便是促生出取代白炽
灯和荧光灯的新一代节能照明巨大市场。
日本的企业及大学为开发高亮度蓝色LED做出了巨大贡献。在GaN LED的研究阶段,
名古屋大学赤崎勇教授(现为名城大学特聘教授)领导的研究小组取得了出色的成果。
在之后的实用化及高亮度化阶段,日亚化学工业的中村修二(现为美国加州大学圣塔芭
芭拉分校教授)发挥了重要作用。1995年1~3月《日经电子》连续报道了中村从GaN类
蓝色LED的研究开始到产品化为止的故事,此次本站将刊登该系列报道,希望能向读者

啥叫account manager?啥叫flow的存货做prop ? 知道broker dealer里有个叫Chinese
Wall的东西吗?
还说knight的flow好几年都没挣钱了。他们flow这几年挣得钱超过所有做flow的公司,
包括Citadel。flow的revenue是Knight annual net income的好几倍。
自以为懂得挺多的,其实很多基本常识都搞错。别再这里现眼了。

This is a typical maximal flow question. Set the flow limit of
each edge to be one. The maximal number of couriers equals to the
maximal flow from s to t.
To compute the maximal flow, you can figure out the mimimum cut of the
graph, the according to a "maximal-flow-minimal-cut" theorem, they equal.

Time of flight will give you information of flow direction, while contrast
MRA doesn't. As long as there is flow in a vessel, retrograde or ante grade,
it will light up with contrast enhancement. In time of flight, retrograde

来自主题: _pennystock版 - 研究财务报表有没有用?
这个。。。首先要看行业。。。不同行业之间财报比较是无用的。
OPERATING CASH FLOW好也要看是什么原因啊。。。
有时候相对于CASH FLOW,我还更相信EPS。。。
例如一个公司,今年扩大生产,开了分厂,这样他们的CASH FLOW会很差。你觉得这个
公司就完了?相反其实公司发展的很好。
我觉得任何时候,只单纯的看EPS, CASH FLOW什么的,都是不科学的。一般有两种策略:
1。你可以细致研究/跟踪几个公司的报表,以及行业动态。每次ER出来,你要充分的将
报表和公司的运营联系起来。只看报表,你只能看到过去。我们要看到未来,所以你要
充分理解这个公司,最近发生了什么事,它的报表,每一行,都表达了公司的什么状态
。以公司现在的处境,将来最可能的发展情况是怎样的。这才是正确的解读报表的方法。
2。如果纯看数据指标,也可以。例如你只看CASH FLOW, EPS, P/E.P/B,P/CF之类的数
据,那么你的分析一定是非常不全面,有偏差的。所以你只能依靠巨大的运算和数据库
来做。例如你想选取P/E较低的股票来买,那么你买一个就肯定不行。你可以买1000个

chronicle如是说的证据呢?无图无真相啊。你自己当面写下的500包子白纸黑字都能抵
赖狡辩,你叫人怎么相信你?
ebb and flow是陆军官方战史,如果真有2个营损失惨重,怎么可能对这种战斗只字不
提?云山也就1个营损失惨重吧?可是花了大篇幅详细描写的。
“相当部分”语焉不详。假设一个营800人,损失30%即失去战斗力的话。损失10%约80
人也可视作“相当部分”,但是从数字上看并不大。
在Ebb and Flow里面提到美3师的活动,一直都在说狗狗特遣队,只字未提什么社仓里
剑山岭,然后就给出400人的伤亡数字,给人的印象这400人伤亡大多来自狗狗特遣队,
和什么社仓里剑山岭根本没有关系啊。
还有一点,ebb and flow那个统计数字是截止12月10日做出的,有不准确的成分在内。
比如美7师光MIA就有2650人,但是实际上后来新的统计数字显示美7师全部战斗减员不
过2000人左右,在新兴里战斗期间的战斗减员是1500人左右。主要是失踪有其暂时性,
有的可能无伤归队,有的可能归队后转化成非战斗负伤等。所以即使Ebb and Flow里给
出了美3师400人的伤亡总数,其... 阅读全帖
