The term spread—the difference between long-term and short-term interest
rates—is a strikingly accurate predictor of future economic activity. Every
U.S. recession in the past 60 years was preceded by a negative term spread,
that is, an inverted yield curve. Furthermore, a negative term spread was
always followed by an economic slowdown and, except for one time, by a

一般防spread,如果不用盯人的话,slot receiver那里各种short route漏洞太多,比
如X和Z跑deep route把CB往后逼,然后Y跑个flat route,边线那边就空了,OLB要从
box跑去边线追Slot receiver太远了。如果让CB留在flat区域jam一下X或者Z就放走的
话,X和Z就跑个hook 或者out route,safety来不及过来补位的。如果safety在开球前
就站位很浅,X和Z可以考虑跑deep route玩big play。总之不用盯人的话防传球会很困

迎指正。
大家意见最多的是打法名称。在我看来,大学队的打法,都是职业队派生出来的。大学
队的好教练,基本都在职业队作过教练或助教。比如Saban是Bill Belichick的助教,
他就自称打的是Belichick的体系。
职业队的打法,粗略的分,一种是以running为主的Pro,另一种是以passing为主的
WastCoastoffense.以此又派生出多种。WastCoastoffense因为要有好的QB,和receiver
,大学队不可能全盘接受,因此派生出多种打法。Spreadoffense,在我看来,就是
Westcoastoffense的派生,当然这点你可能有不同意见。我的理由是SpreadOffense在
大学的应用比Westcoast要晚。SpreadOffense盛行后,又有许多派生,比如Spurrier的
Run-Based Spread,Meyer的Option-based spread.在SEC,Spread的鼎盛时期是

讲了许多Saban的手下都做了主教练,招他们的队原意是把Saban的打法带来。但他们都
已改弦更张。只有Muschamp好像要把Saban的理念进行到底。但不知这杆大旗能抗多久。
Football的打法一直是在推陈出新,每当一种打法所向披靡时,另一种相克的打法已在
孕育之中。BAMA已立于NCAA之巅几年了,Saban打法的克星已出现。
2009年SugarBowl,Utah 对BAMA.赛前媒体一面倒的吹捧BAMA,认为这是当年几个bowl中

IN GOD'S WAY
SCHOOL-DAYS
I.
In the melting snow on the hill-side by the sea, in the last rays of the
evening sun, stood a boy of fourteen, awestruck. He looked toward the west,
out across the sea; he looked toward the east, over town and shore and the
broad hills; in the background still higher peaks rose far away in the clear
sky.
The storm had lasted a long time; it had been more terrible, too, than any
the old people could remember. In ... 阅读全帖 |

AUM,asset under management,指代hedge fund下面的asset
spread:ask 与bid之间的距离,比如stock,会有limited price和market price,
limited price是你想指定的价格,而market price是money market和 2级市场买卖双
方愿意成交的价格。
比如APA,bid price 75.16, ask price 75.18,对于一个cap size 30B的company,
这样的spread很小。
比如APA weekly option,因为是根据股价变化加速变化,所以,bid 1.0, ask1.5,
这里的spread就很大。
楼主解释的bond spread,
bond 2种,一种是with coupon,这种一般mature date前稳定分红的,带yeild的,
一种是without coupon,这种mature date长,但是买进的时候deep discount,比如30

c***s 发帖数: 2 | 42 When you calculate OAS of a callable bond, assume the market price is known,
there are two ways:
1. to build a interest rate tree, and add a spread to each node of the tree
and price the bond cash flows without the callable feature and until you
match the market price; the spread is on top of the forward rate
2. just use the bond (zero) curve, add spread on each curve instrument until
you match the market price. the spread is on top of the zero rate
so when to use each method and difference? |

c**********s 发帖数: 295 | 43 OAS, by its name, is the option adjusted spread. you turn off the callable
feature, which is the option part, what you are calculating.
with the callable feature, 1 is oas, 2 is zvol oas, which means what spread
you will make if there is no vol. the difference between 1 and 2 is the
spread you are paying for the vol.
in fact as i remember the spread is on top of the short rate. |

D********n 发帖数: 978 | 44 假设flat CDS curve, flat discount curve,最简化day count,我们可以用q来代表q
uarterly survival probability, 用d代表quarterly discount probability.
换句话说,如果survive第一个quarter的概率是q那么survive第一年的概率就是q^4. 推
导一下可知:
CDS par spread = (1-R)*(1/(q*sqrt(d))-1/sqrt(d))
R是recovery rate.
用两年的libor推出d = 0.99777。其实d并不重要。你可以令d = 1, 对结果影响不到一
个bps.
用上面的公式,结合题目给的quote, 可以算出
q_A = 0.9756
PV01_A = $35507
q_B = 0.9524
PV01_B = $32019
用这些结果你很容易算出Default Leg values.
Portfolio CDS的PV01和default leg value就是single name的PV01的notional weight

options是衍生物,我理论知道的不多,
不过知道比较轻松的方法是卖options来挣premium
卖options的方法很多,基本上出发点是把别人花钱买risk,你卖risk。
看歪脖的最近文章关于10x的感慨,
做了100个亏掉99 个,一个成功,最终take risk 的损失90%
对于卖risk就是另外一面,100个10x的dreamer就造就了进nX的回报。。
当然卖options 也是有风险的,如何规避风险呢?
根据leverage的不同程度,decay的速度等,你可以进行各种组合。
最常见的方法,你卖个covered call, 买股票。
股票不decay, 卖的covered call decay。。
