Short (finance)

[不指定 2008/05/01 09:40 | by mlzy ]
In finance, short selling or "shorting" is the practice of selling securities the seller does not then own, in the hope of repurchasing them later at a lower price. This is done in an attempt to profit from an expected decline in price of a security, such as a stock or a bond, in contrast to the ordinary investment practice, where an investor "goes long," purchasing a security in the hope the price will rise.

The term "short selling" or "being short" is often also used as a blanket term for all those strategies which allow an investor to gain from the decline in price of a security. Those strategies include buying options known as puts. A put option consists of the right to sell an asset at a given price; thus the owner of the option benefits when the market price of the asset falls. Similarly, a short position in a futures contract, or to be short a futures contract, means the holder of the position has the obligation to sell the underlying asset at a later date.

Long (finance)

[不指定 2008/05/01 09:37 | by mlzy ]
In finance, a long position in a security, such as a stock or a bond, or equivalently to be long in a security, means the holder of the position owns the security and will profit if the price of the security goes up.

Similarly, a long position in a futures contract or similar derivative, means the holder of the position will profit if the price of the underlying security goes up.

山姆：4月30日汇市实战分析

[不指定 2008/04/30 20:24 | by mlzy ]
美元最近又呈下跌趋势。之所以我对美元如此关注，是因为我也持美元观望中。

　　 和讯特约
（和讯财经原创）

　　 美元似乎市场已经看到反转的希望，但现在谈论这个似乎为时过早。个人对美元的预测是今年呈现U形的走势，目前没有走完U形有左侧部分，按这个预计，美元仍然将震荡下行，但是幅度远小于过去。
（和讯财经原创）

　　市场认为美元反转的理由在于：
（和讯财经原创）

　　一、欧元区本周经济数据不好，法国消费者信心指数下滑到二十年新低，上周德国IFO也告下滑，前者个人认为对欧元的影响不大，反倒是后者有待观察；
（和讯财经原创）

　　二、美元可能在明晨的利率会议上停止降息。从而使市场产生美元降息周期已经暂停的预期；

如果你做不到如下几点,请千万要离开投机市场  

[不指定 2008/04/30 20:15 | by mlzy ]
转贴，原帖地址已然找不到。我觉得自己很可笑，因为一个学习投资、学习金融的人，在中国股市最高的时候入市，在现在最佳时期，却又没有钱继续入市了。

持股等待。也许会涨到自己入市的时候，但这已经不能算炒股了。

如果入市，那么就趁现在。。。如果翻本。。。趁现在。。。

可怕的中国股市。

Example Citations:
The Flemings lot are now talking about "regret aversion," investors' inclination to sell their winners and stick by their losers, and the "house money effect," where people are more likely to bet recklessly in casinos with money they have recently won.

Prospect theory

[不指定 2008/04/29 14:45 | by mlzy ]
Prospect theory is a theory that describes decisions between alternatives that involve risk, i.e. alternatives with uncertain outcomes, where the probabilities are known. The model is descriptive: it tries to model real-life choices, rather than optimal decisions.

这个理论很有趣的一点是：人们对金钱上的收入和损失的心里感受是完全不平均的。当你得到一点点的时候，你满足感会上升的很快，以至于你持续得到很多钱以后，你的满足感反而上升的变慢了；当你失去一点钱的时候，你很痛苦，但是随着你失去的越来越多，你反而不会像以前那么痛苦了。

Bayes' theorem

[不指定 2008/04/28 22:40 | by mlzy ]
                                      

In probability theory, Bayes' theorem (often called Bayes' Law) relates the conditional and marginal probabilities of two random events. It is often used to compute posterior probabilities given observations. For example, a patient may be observed to have certain symptoms. Bayes' theorem can be used to compute the probability that a proposed diagnosis is correct, given that observation. (See example 2)

As a formal theorem, Bayes' theorem is valid in all interpretations of probability. However, it plays a central role in the debate around the foundations of statistics: frequentist and Bayesian interpretations disagree about the ways in which probabilities should be assigned in applications. Frequentists assign probabilities to random events according to their frequencies of occurrence or to subsets of populations as proportions of the whole, while Bayesians describe probabilities in terms of beliefs and degrees of uncertainty. The articles on Bayesian probability and frequentist probability discuss these debates at greater length.

对一些师弟师妹的忠告

[不指定 2008/04/28 09:27 | by mlzy ]
人贵在有自知之明

什么样的人，就能成什么样的事情

想要做成一个好事情，就得前期花很大功夫去培养基础，以及必备的素质

在生活方面

千万不要自称“帅哥”或者“美女”

更不要到处去自称帅哥或者美女

这样就没有自知之明了

于是，这种心理和行为，成为你的弱点，并且在这一点上，你很容易被人伤害。

天下大大咧咧自称帅哥的人，首先要自然条件过关，同时史书礼乐，无一不通，五经杂谈，天文地理，无所不晓，上的厅堂，入得厨房，笑面如花，身后余香，胸有大志，人怀奇才，不卑不亢，交友四方；为父母可割肉熬药，为朋友能两肋插刀。。。。这些点，你们这些自称帅哥，以及到处跑来跑去自称帅哥的，做到了没有？做到了，就可以当之无愧，脸不改色的自称帅哥了。。

别人喊你帅哥，不是你的错，如果自己也喊自己帅哥，并且把自己当成一个宝贝疙瘩，那就是自己的不对了。

为人低调，可保一生平安。
