这个策略是我翻译网上的: (未名发帖也太烂了, 总是断行)
比如你50块买的股票, 现在跌到40了,你最好的挽救这艘沉船的方法
就是用ratio call spread策略. 这个策略适合你的损失从-10%到-50%不等.
如果下面股票开始涨了, 你能迅速回本, 但是继续跌的话, 就跟你原来持有一样.
也即买1个at the money, 40块的call, 同时卖2个45块的call(这个strike 45的
选择,一般是40加上你损失的一半(也即50-40=10的一半,5),
使得买/卖call的成本基本互相抵消.
之所以叫ratio call spread, 是因为买1份call, 卖2份call, 比例ratio是1:2,
叫spread,是因为有同时有买和卖.
一般从2个月到期的call开始选, 使得买卖call的成本相抵消,

楊百萬是個騙子。騙子的問題是不會去核對基礎信息。也就是遲早會自己騙自己。例如
楊百萬不會承認aapl 90多的時候他讓別人割掉。
Alpha go的後續是alpha go zero和alpha zero. 楊百萬重複說了很多次人家解散了。
Alpha go zero的文章
講兩個Q table可以讓預測誤差和feature更加不相關,所以性能提高了很多。不久前還
有alpha zero的一個文章出來。
簡單說alpha go - alpha go zero - alpha zero
12月才出了一個science文章。
楊百萬可憐的腦子理解不了這條線。於是把人家解散了。

标 题: [KJPT]谷歌在补丁发布日前披露Windows漏洞 微软怒了
发信站: BBS 未名空间站 (Tue Jan 13 00:29:53 2015, 美东)
编者按:微软和Google的关系在近几日急转直下,原因在于,Google披露了一个Windows 8.1 的安全漏洞,而微软还未对此做出更新。
Google旗下的Project Zero项目小组上周公布了微软Windows 8.1的一个漏洞,该漏洞能允许低级别的账户成为系统管理员,从而得以访问计算机内敏感数据。
其实,Project Zero很早就发现了该漏洞,并与2014年10月31日告知了微软。按照Project Zero的说法,如果告知后90天内微软没有做出修复,该漏洞就会被公开。
为什么Google有这样的权力?Google在今年7月宣布Project Zero计划,它由一组安全研究人员负责,唯一的目标就是追踪和修复漏洞,维护所有互联网用户的安全。
项目小组主要针对“零日漏洞(zero-... 阅读全帖

Qualitative explanation for why there is a vol smile in stochastic
volatility models from a market-making perspective:
First, let's step back and look at the standard Black-Scholes world. Why do
options have value over intrinsic value? Because they have positive Gamma.

会不会把三体人招来

在2005年5月,美国宇航局宣布航海家一號已經在2004年12月,在距離太陽94天文單位
的地方越過終端震波進入日鞘中
2010年12月,旅行者1号已经感受不到太阳风了。
33年的太阳风和行星引力加速,旅行者1号目前是还在工作的速度最快的人造飞行器。

PASADENA, Calif. – The 33-year odyssey of NASA's Voyager 1 spacecraft has
reached a distant point at the edge of our solar system where there is no
outward motion of solar wind.
Now hurtling toward interstellar space some 17.4 billion kilometers (10.8
billion miles) from the sun, Voyager 1 has crossed into an area where the
velocity of the hot... 阅读全帖

Rufus Sixsmith leans over the balcony and estimates his body’s velocity
when it hits the
sidewalk and lays his dilemmas to rest. A telephone rings in the unlit room.
Sixsmith dares not
answer. Disco music booms from the next apartment, where a party is in full
swing, and
Sixsmith feels older than his sixty-six years. Smog obscures the stars, but
north and south

没有具体做过这样的glm,但是如果zero的时候出问题,有zero-inflated和zero-

Amazon has just made another move that indicates the company is taking its
expansion into mobile gaming more seriously than just a way to tout how it,
too, has “exclusive” content to offer via the Amazon Fire TV. For the
first time, Amazon has launched a mobile gaming app on Apple’s App Store.
But before you get all worked up, we have to point out that the new app, Sev

Hamas Gives Counterproductive Thumbs-up to Ground Zero Mosque

As the nation tries to suss out how, exactly, President Obama feels about
the ground zero mosque — it's really an Islamic community center two blocks
from ground zero, but "ground zero mosque" continues to have a much better
ring to it — a more unequivocal endorsement is sure to add fuel to the

Why Is Deflation Bad?
A number of readers have asked me to explain why deflation is a bad thing;
and the truth is that while I’ve alluded to the issue a number of times, I
’m not sure if I’ve ever laid out the whole case. So here goes.
There are actually three different reasons to worry about deflation, two on
the demand side and one on the supply side.
So first of all: when people expect falling prices, they become less willing
to spend, and in particular less willing to borrow. After all, when... 阅读全帖

Everybody have dreams, but I don't. Why? Because I was so scared, my wife is
so scared, my children are so scared that

kill all Chinese to remove debts via a kid's mouth, and, ABC braodcast this
to the world and they said this is a joke, which we Chinese cannot
appreciate. We do not want to be killed, and we want to live.

Moscow (AFP) - Russia could reduce to zero its economic dependency on the
United States if Washington agreed sanctions against Moscow over Ukraine, a
Kremlin aide said on Tuesday, warning that the American financial system
faced a "crash" if this happened.

Per wiki:
The third law of thermodynamics is sometimes stated as follows, regarding
the properties of systems in equilibrium at absolute zero temperature:
The entropy of a perfect crystal, at absolute zero kelvin, is exactly
equal to zero.
At zero kelvin the system must be in a state with the minimum possible
energy, and this statement of the third law holds true if the perfect
crystal has only one minimum energy state.

below 1 nanokelvin (one-billionth of a degree).

Total mind control of the masses program:

2. Take control of emerging market governments through massive loans where
it is apparent that the governments will not be able to repay and then will
be subject to control through capital ;markets or through the International
Monetary Fund. Use the IMF "privatization" and "austerity" programs to take
control of national assets and sell them to cronies at low prices.
