q********g 发帖数: 10694 | 1 Neutral or non-directional strategies
Neutral strategies in options trading are employed when the options trader
does not know whether the underlying stock price will rise or fall. Also
known as non-directional strategies, they are so named because the potential
to profit does not depend on whether the underlying stock price will go
upwards. Rather, the correct neutral strategy to employ depends on the
expected volatility of the underlying stock price.
Examples of neutral strategies are:

In the nine postseasons since 2004 (the “Dwyane Wade era”), the Heat are
13-3 in playoff games reffed by Dan Crawford and 48-40 in all other playoff
games in that span. To control for effects like home/road or playing better/
worse opponents, it may be better to look at the expected win-loss for the
Heat in those games given the pre-game point spread (betting line) for each
game.

S*******r 发帖数: 11017 | 5 最近鳄鱼有点触低反弹的意思,但遗憾的是似乎这种反弹跟鳄鱼首发QB JOHN BRANTLEY
没啥关系。主流球迷观点是,TREY BURTON或者JORDAN REED才是引领鳄鱼扭转胜的关键
。BRANTLEY的球风打法实在没法适合鳄鱼。
我记得赛季前展望本赛季的时候,MEYER说过鳄鱼进攻将会为BRANTLEY做变动;而球迷
们认为,鳄鱼2010赛季的BRANTLEY将如同2004赛季UTAH的ALEX SMITH般。
赛季已经过去大半了,BRANTLEY不但没有成为ALEX SMITH,反而快把自己的首发位置给

我特意回去找了UTAH2004赛季的视频来看,看看SMITH当年是怎么打的。此君身子骨也

MWC里是个跑动威胁,平均看下来每次RUSH4-5码总是有的。这点就是BRANTLEY在SEC没

c*******y 发帖数: 1630 | 18 所以我说kelvin同学你还要多读几年书,一点没冤枉你。
你要是真想比较spread和直盘,我可以推荐几本入门书给你。
跨期套利只不过是统计套利,如果是bullish spread,也看品种,对于可以储存的品种
,同一个作物年的跨期bullish spreading是可以做到绝对的无风险的,当然你也可以
说存储的仓库有可能失火了,或者保存失当,或者各种各种期货以外的交割的风险。
bearish spreading本身就是统计套利,所有统计套利都是有风险的。但是你要说这个
风险跟直盘差不多,那就是太失水准了,我前面已经提到过spread的保证金要小得多,
大概只有直盘的20%,另外spread在方向看反的时候仍然可能是盈利的,直盘方向错了
,你给我盈利看看?
另外LTCM做的根本不是什么arb。去了解一下历史先。 |

x*********n 发帖数: 28013 | 24 1. 首先有一个问题,你buy 1个put同时sell 2个put,在broker看来等于买一个put
spread加上sell一个naked put。put spread不需要太多margin,但卖naked put
会消耗巨大的margin。具体来说,一般broker会收取20%-25% X stock_price
X number_of_contracts. 比如现在XLF价格是23,那么卖一个naked put需要的
margin:25% x 23 x 100=$575。而卖一个naked put能得到多少钱?
按60天expire,15%波动率,strike=23,XLF=23.5算,put价值$0.32。
也就是能够收到$32的premium。但你付出了$575的margin,接近持仓量的20倍。

这个有原因的,像OSU,TT,包括houston这种以传球为主的spread team,QB的传球绝

这些球队QB的 completion rate都很高,再加上每场传球40+,数据绝对的好。

trader1688上也有人提过pair trading,并有人表示怀疑。
这个idea是80年代摩根斯坦利的人提出来的idea,然后finance行业的人又比较liquid

基本的想法是,high correlated的two stocks,spread比较稳定,假如某个时刻出现
了比较背离average的情况,基本上是可以认为一个overprice,一个underprice,然
后long那个underprice的,short overprice的symbol,以期spread恢复至正常。

The way led along upon what had once been the embankment of a railroad. But
no train had run upon it for many years. The forest on either side swelled
up the slopes of the embankment and crested across it in a green wave of
trees and bushes. The trail was as narrow as a man's body, and was no more
than a wild-animal runway.

By EMILY BAUMGAERTNERSTAFF WRITER

It’s a virus scientists have never seen before. Health officials don’t

SEOUL–North Korea’s not saying a word about deaths or illnesses from the

China and is taking a toll in a country with a dismal health care system and

Is Nancy Pelosi trying to use reverse psychology on Republican voters?
Suspend disbelief for a moment, and pretend that Pelosi knows how to use
reverse psychology.
If that is difficult for you to do, then pretend that Pelosi read about
reverse psychology in Psychology Today while waiting for a botox treatment.
Now keep that thought in mind as you read the following excerpt from

发帖数: 1 | 48 Can Hepatitis B be spread through food?
Unlike Hepatitis A, it is not spread routinely through food or water.
However, there have been instances in which Hepatitis B has been spread to
babies when they have received food pre-chewed by an infected person.
What are ways Hepatitis B is not spread?
Hepatitis B virus is not spread by sharing eating utensils, breastfeeding,
hugging, kissing, holding hands, coughing, or sneezing. |
