每天收盘前出对第二天以后的预测。
自俱乐部成立以来的预测：
Aug. 11, 2011
今天大盘高开高走，各指数均有巨大升幅。成交量进一步缩小，显示市场逐步摆脱恐慌
。虽然VIX还处在比较高位，但是随着利空被price in,像前几天那样大幅连续狂跌的情
况应该已经过去。以后市场就算还要跌，也会是一个正常的升跌幅度。VIX会逐渐下落
。IV也会降下来。
从NDX日线图看，市场冲出前三天拉锯的区域，显示短期还会向上。
5-day RSI:
SPX 43.5，Dow 42.1，rut 42.2，Nasdaq composite 44.3，NDX 45.5.
从底部形成的感觉看，5-day RSI能到55-60.
如果市场一天升，一天跌的话（明天跌），则可能要多等一两天。
如果明天继续升，则在5-day RSI 55-60左右可以close position.
明天以后的情况不是一定不会继续升。只是看不清。要是碰到第二天期指大低开，就很麻烦。

发帖数: 536 | 2 Actually, this is a really good question. First, we need to know the
definition of risk free portfolio or how to capture the risk in terms of
math. In my opinion, you have to go to the VaR. The risk free portfolio
should be defined by VaR_1(L)=0, which means that we have 100% confidence
that the probability that the loss L exceeds 0 is no larger than 0. Here the
loss L is defined by $L=V(t, ...)-V(t+\delta t,...)$. Note there are
several different kinds of definations of L, e.g. discounted loss ... 阅读全帖 |

1. arbitrage free
2. replication
3. risk neutral 就是求 p， 1-p 那种；
二叉树的极限 是brownian motion；
这种情况p, 1-p 就变成 risk neutral measure 了, which measures brownian
paths。
有了risk neutral measure, 就有了PDE.
PDE 可能也可从别的东西，推倒出来.

用option当然可以，但不是必须，
用option可以得到更高的leverage，
但是缺点是散户量小，不容易实现market neutral。
比如1.37的hedge ratio，你要long 137和short 100个才能实现。
13和10就不那么好，而且不容易adjust，看附图就知道不怎么neutral的情况。
说stock不便于对冲，这点我不懂你什么意思。
这本身就是market neutral的strategy。
我测试过DISCA和AXP（paper account)，追踪了至少2个月，涨跌幅从来没超过3%的，
但是这反过来说明这不是一对好的pair。
别的pair，没有任何leverage，一年可以做到100%以上的也有，如果我实际做stock到

今天大盘走势强劲，各大指数均有较大升幅。成交量萎缩。RUT转强。NDX日线图显示上
升图形。从VIX和P/C ratio看，市场恐慌还没完全消除。
5-day RSI:
SPX 54.2，Dow 54.8，rut 52.7，Nasdaq composite 53.8，NDX 54.1.
从5-day RSI来看， 市场已经接近或达到通常这种情况下的反弹水平（5-day RSI到50-
60）。
但是NDX日线图还完全看不出转折的迹象。就是说，在这里有点两个方向都没把握的感
觉。操作上好像空仓观望或持股观望都可以。
这是一个close call.
在考虑各种因素，概率后，决定还是以NDX日线图为依据，维持短期趋势向上的判断，
直到NDX日线图出现转折信号。
但是随时注意反转迹象。明天NDX 2180 是重要点位。如果被向下打破，我的model自动
进入空仓观望状态（neutral 偏bearish)。

Wrong. If there is ever a conflict between US and China, Taiwan will
inevitably lean toward US instead of maintaining neutrality. In fact, even
by maintaining neutrality it would be assisting US, because China would
still have to devote resource to guard against this front, when China
already need every bit of resource to deal with US. As long as the
government in TW doesn't want to merge under ML government, they would do
whatever they can to ensure US wins the conflict. |

朝鲜战争中被俘的美军士兵
朝鲜战争战俘遣返问题是指朝鲜战争后期，交战双方在战俘遣返的原则上陷入尖锐分歧
，成为停战的最大障碍。1951年12月，朝鲜停战谈判进入战俘议程后，朝鲜民主主义人
民共和国与中华人民共和国派遣的中国人民志愿军提出停战后双方战俘应“全部遣返”
，主导联合国军的美利坚合众国则坚持“自愿遣返”（后修改为“非强制性遣返”）。
双方为战俘遣返的原则进行了一系列激烈的外交和军事斗争。1953年3月... 阅读全帖 |

你说的那些事故，根本造成的是短路故障。
你根本没搞清楚星形接法三相变压器失去接地neutral和你用户端断零的区别。
变压器的neutral跟你那根零线一点关系都没有，近变压器端就接地了。
科普你一下，美国这边，零线都可以不需要空气开关保护的，因为零线其实是远端接地
的，你的空气开关只经过火线。
空气开关有两种，single pole和double pole, 知道用法和区别吗？ |

In the 1978 case, Regents of the University of California v. Bakke, the U.S.
Supreme Court ruled that using racial quotas in college admission decisions
violated the Equal Protection Clause. The Equal Protection Clause, included
in the Fourteenth Amendment to the U.S. Constitution, affirms that "no
state shall deny to any person within its jurisdiction the equal protection
of the laws." While this landmark decision eliminated racial quotas, it did
allow race to be co... 阅读全帖 |

电灯开关是在powerwire中间装的电闸
你要找neutral应该去outlet

线就是，然后准备一段白线，和那些白线卷在一起，接到你的新开关就好。
我换了一些，有一个开关honeywell 740b需要neutral，发现neutral都藏在盒子深处呢。 |

我目前自己能搞定的是single pole或者3way的。
一般带neutral的开关尽量不要买，智能开关很多都不需要neutral,例如lutron的
caseta。 |

he did a good job of making a semi-neutral film.
How much research into the case have you done outside of the documentary
itself to verify that it is as neutral as you contend? Do you disagree with
all of the "points left out" lists that others have made about it?
