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

来自主题: NCAA版 - John Brantley和URBAN MEYER的战术
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
弄丢了。

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

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。

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。

6月初纳指小崩、IV 和 IVR 飙高的时候。
现在QQQ的52周 IVR = 32,已经有点鸡肋了。
一般而言,IVR > 50% 的环境适合 short IV,
具体策略就是 short vertical spread, short straddle,

期权能够卖个相对高的价钱。
IVR 25-50%,比如现在的 QQQ,
也可以勉强做上述策略,
但是 reward 会降低,risk 提高。
IVR < 25% 的环境,short IV 策略据统计是亏钱,

所以这个辟邪剑法是小学校的安身立命的不二法门,这个也是NCAA精彩的地方。你玩你

09年我鳄的红区打的也很烂,后来MEYER想到一个办法:攻入40码线就开始拨可以直接
TD的PLAY。效果一度不错。
Skill positions上我觉得大12一点不逊色甚至更强。以OKSU为代表的几个大12乃至TX
球队都是那种风格:一个系统QB+一个牛逼WR,10胜赛季跑不了。

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
大多数都是LOS 10yards以内的传球,然后WR利用spread formation搞big play。所以
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。
为这种短传,红区以后,你再也不能spread了,所以红区进攻效率一般不高,今年后半

1In my former book, Theophilus, I wrote about all that Jesus began to do and
to teach 2until the day he was taken up to heaven, after giving
instructions through the Holy Spirit to the apostles he had chosen. 3After
his suffering, he showed himself to these men and gave many convincing

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

这里overprice和underprice都是相对而言,加入两个symbol都涨了,期望的是long那

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.
