MCI, Inc. (formerly WorldCom and MCI WorldCom) was a telecommunications company. For a time, it was the second-largest long-distance telephone company in the United States, after AT&T. WorldCom grew largely by acquiring other telecommunications companies, including MCI Communications in 1998, and filed bankruptcy in 2002 after an accounting scandal, in which several executives, including CEO Bernard Ebbers, were convicted of a scheme to inflate the company's assets. In January 2006, the company, by then renamed MCI, was acquired by Verizon Communications and was later integrated into Verizon Business.
WorldCom was originally headquartered in Clinton, Mississippi before relocating to Ashburn, Virginia when it changed its name to MCI.[1][2]
疫情后，随着愈来愈多企业外移，中国经济持续下行，也让失业率继续攀高，近期多项数据显示经济复苏缺乏动能，中国青年失业率已直逼 20%。专家分析，1970 年代以来的第三次失业大潮正在席卷中国，短时间不大可能缓解，未来 3 年，失业规模恐持续扩大，而内卷将趋严重。许多大学生如今正面对毕业即失业的困境，但在就业市场哀鸿遍野之际，中国仍宣布 2023 年国防预算将比去年大增 7.2%，让外界批评这种重军事轻民生的政策，不仅让更多人失去工作，也会让中国政府失去民心。
据《大纪元时报》今 ( 7 ) 日报导，1970 年代以来中国经历三次失业高峰。第一次是 1973 年至 1979 年，文革期间下乡的知识青年要求“返城”产生的就业危机，第二次是 1998 年至 2001 年国企改革带来的下岗潮；第三次指 2020 年后，即疫情爆发后，失业规模逐年攀升，预估 2025 年来到历史高峰。
旅美经济学家李恒青分析指出，自己是在文革时代出生的，经历过中国第一次、第二次失业潮，这一次大规模的失业，跟前两次不一样，整体形势越来越不好，他真正担心的是这一代年轻人，最后对未来失去了希望
中国此次失业潮真的只能用“哀鸿遍野”4 字形容。中国经济在企业出走及严格疫情管控下，互联网、房地产、补教全部熄火，高达百万就业机会瞬间消失，加之美中贸易战，企业关厂外移，让青年失业率狂飙。就有网友哭诉，自己投了百份履历都石沈大海。一家山东国企更招聘砍半，只招 1,000 人，报名人数竟高达 10 万，履历如泄洪般涌入，企业为节省成本，还直接动用 AI 先进行淘汰。
包括腾讯、阿里巴巴、微博等大型民营企业，最近几个月都宣布裁员。字节跳动、美团、百度等，在校园招聘上不是征才砍半，就是直接盖牌。

中国国家统计局的数据表明，2022 年中国城镇就业人员比 2021 年减少 842 万，60 来首次下跌。学者预估经济和劳动力市场复苏不容乐观，预计未来 1 至 2 年城镇新增就业人口数目还会下降。且最近三年，中国城镇青年的失业率从约 13% 攀升至超 20% 以上，今年更高，特别是毕业的大学生。
2022 年 7 月，中国青年失业率中 16 岁—24 岁人口失业率占 18.2%，创有历史数据以来最高；去年同期全国毕业大学生失业率为 6.1%，单在上海市，应届毕业生平均就业率只有 32.8%。
中国国家统计局的数据还预计今年大学毕业生有 1,158 万人，将有 800 万大学生失业，创 2020 年 3 月以来新高。
经济滞后发展无能有效地吸收这些新增劳动力。房产崩盘，民企倒闭，商店关门等，后疫情时代，中国经济不断下滑，国内国外的经济环境趋向恶劣，又没有良性政策支持企业发展。
而针对在岗失业人口方面，文章列举，A 股上市企业平均职工数量比疫情前缩水 11.9%、10% 的企业注销或停止运营，包括腾讯、阿里、美团、百度今年第一季度裁员率达 9%，旅游、教培、房地产业裁员更是严重。
全国青年全职职工约 2.5 亿人，若依 10% 失业或裁员率推算，青年在岗失业人数约 2,500 万。加上近三年约 2,300 万农民工因为失业而返乡，其中 60% 为青年人，意味有 1,400 万人失业返乡。综合以上数据推算，疫后三年共新增 5,400 万青年失业人口。

李恒青认为，当局在部分数据统计上做手脚，实际情况更严重。他举例，以“应届毕业生总数”来说，不少学校为了刻意压低毕业人数，采取不发给学生毕业证，直至毕业生找到工作了，才把毕业证颁发出去。有学生为了出国，需要毕业证书，就必须透过熟人，去请学校开毕业证书，因涉及当局对于毕业生的就业考核，这就是造假！
河南省教育厅 5 月 30 日下发“百日冲刺”方案，要求毕业生在 8 月 31 日前找到工作，甚至下令“零就业家庭”和长期未就业的毕业生必须“动态清零”。网友质疑，连就业问题都想搞运动，想必是解决不了问题。
台湾中华经济研究院助研究员王国臣也分析指出，中国大陆失业率的统计确实存在遗漏，首先它抽样的样本比例过低，不到 0.07%，其次，抽样对象倾向于有居住地址、有固定居所的人，农村很大比例没有纳入调查，近期官方公布 20.4% 的青年失业率，还不包含农村。
王国臣认为 :“百年不遇的疫情”或许只是作者表面的说法，更根本的原因是中国大陆当局对于民营企业的打压，才是造成青年失业率高企的主要原因，包括 2019 年以来的国进民退，对于网络科技公司、房地产行业的监管引发的问题，这些民营企业才是真正吸纳劳动力的主要企业。
St Louis Fed's Bullard says rates will need to be increased further to become sufficiently restrictive
2013 was an incredible year for the stock market. In fact, for the past two years, stocks have been on an unbelievably good run. Which begs the question: What should you do to hedge your bets?
I’ve seen the stock market rise and fall many times during my career and found it prudent to take some profits off the table during the good times—thus limiting losses during a market correction. In the past, we investors considered diversifying some of the money we had in stocks by investing in other assets that provided decent yields, such as bonds.
But those other options simply aren’t attractive now. Bond yields are low, and interest rates may soon rise. So what are we to do in terms of reducing our exposure to stocks while also keeping our money working for us?
One option investors and advisors may consider is exploring additional investments in long/short equity mutual funds.
(Read more: Stocks still tops, advisor survey finds)
The idea is to invest in funds that employ a strategy of owning attractive investments (longs)—where the manager is betting that these stocks will increase in value—while shorting overvalued/unattractive companies (shorts), which are bets that these stocks will lose value. When done skillfully, this is one way investors can maintain exposure to stocks while having reduced exposure to volatility and the market as a whole.
What makes this strategy so appealing now is that not all stocks gained at the same rate in 2013. In fact, according to investment management firm Eaton Vance, lower-rated stocks went up more than those more highly rated by Standard and Poor’s (S&P): C-rated stocks were up 57.7 percent through Nov. 30, while A-plus-rated stocks were up a more modest 22.3 percent. The S&P 500 itself was up 29 percent.
This performance discrepancy creates an opportunity for a fund to go long high-quality companies while shorting low-quality stocks.
When it comes to choosing a fund, be aware that long-short managers generally employ one of three philosophies:
When it comes to deciding what to do in portfolios, I like to compare it to driving a car that’s gaining a bit too much speed for comfort. Sure, you can take your foot completely off the gas and hit the brakes, like cashing out of stocks and going to cash. Our goal with the hedged equity strategy is to just ease up on the gas and maintain a little more control.

一提起忧虑，不但非基督徒常有，基督徒也不例外。忧虑的多少，常因各人的性格、身分、环境……而异。一个多愁善感的人，往往比一个乐观者有更多的忧虑；一个身负重任者，往往比一个职任轻省者有更多的忧虑；一个身处恶劣环境者，往往比一个身处安逸环境者有更多的忧虑。当然，世事常有例外，富裕者不一定常高枕无忧，而贫困者也不一定常辗转难眠。
一个人所忧虑的事，乃是他所关心或重视的事；漠不关心的事，通常是不会为之忧虑的。有些人为着他们的健康忧虑，有些为着他们的事业忧虑，有些因亲爱的人不在身边便一直为他挂虑，有些人因患上绝症而满怀忧郁……。
有许多的忧虑是莫须有的或是自找苦吃的，尤其基督徒。明知贪财是不应该的，常有基督徒为了贪图财利铤而走险，心中自然充满忧虑；有些则为了争取名望地位或达到其他的目的而不择手段，心中自然充满忧虑。
有些忧虑却是合理的。基督徒面临试探时深恐跌倒是很自然的事；身为基督徒父母者为儿女的救恩、灵性忧虑是合情合理的事（若无，反而是不负责任）；为着教会的事工、弟兄姊妹的需要忧虑，反映一个人是否爱主……。虽然如此，对于合理的事过分的忧虑，乃是对神的不信，仍是不应该的。
不论我们如何面对忧虑，却都是无济于事的。面临商场风暴，市价猛跌，虽昼夜忧虑，辗转难眠，甚至因而神经衰弱，市价不会因此上升一分！面临工作场所诸般的困难，虽忧虑重重，也不会使这些困难丝毫减少。亲爱的人患了绝症，为他废寝忘食，他的病症不会因此有任何好转。我们都知道忧虑于事无补，却仍然忧虑，我们的困难、矛盾就在此。
基督徒之所以忧虑，是因我们信不过神。我们以为神不顾念我们，不能或不愿意帮助我们，并且我们自以为能为自己解决问题－－这就是问题的症结。我们自高、自信，而不信靠神。
因此彼得在这里告诉我们除却忧虑的办法：「所以你们要自卑，服在神大能的手下，到了时候，祂必叫你们升高。你们要将一切的忧虑卸给神，因为祂顾念你们。」（彼前五６，７）根据圣经原文，第６、７节的经文原是一句话（sentence），而不是两句，因为原文「卸给」（casting）在文法上只是一个分词（participle），不是一个动词（verb）。中文圣经与一些英文圣经版本把第６、７节分开，因此我们常把第７节单独拿来思想。其实综合第６、７两节经文，彼得乃是告诉我们除却忧虑的秘诀－－谦卑。将我们的忧虑卸给神是谦卑的一种表现。除非我们肯谦卑，服在神大能的手下，我们无法将我们的忧虑卸给神。只要我们自以为是、自以为能，我们不会信靠神，并将我们的忧虑卸给祂。
另一方面，彼得也提醒我们，神不但能，而且顾念我们。祂爱我们无微不至，因此我们尽可放心将我们一切的忧虑卸给祂。神知道我们一切的忧虑、困难、试探、危险……。
彼得劝我们要将一切的忧虑「卸给」神，「卸给」乃是交托的意思，交托自然包括祷告。因此彼得的教训与保罗的相似：「应当一无挂虑，只要凡事藉着祷告、祈求，和感谢，将你们所要的告诉神，神所赐出人意外的平安，必在基督耶稣里保守你们的心怀意念。」（腓四６、７）
对付或除去忧虑的办法乃是谦卑、交托、祷告。藉着这些神让我们看到自己的愚昧、无知与无能。当我们把不应有的忧虑（如上所述：贪心、野心）带到神面前，神会让我们看到这些忧虑是莫须有与自找苦吃的，要我们放弃；倘若我们的忧虑是合理的，神要我们将这些忧虑卸给祂。
生活在这个罪恶的世界里，我们难免有诸般的忧虑，不然圣经就不须常提醒我们不要忧虑了。彼得提醒我们要将「一切的忧虑」卸给神；保罗劝我们「应当一无挂虑」；主耶稣教导我们：「不要为明天忧虑，因为明天自有明天的忧虑；一天的难处一天当就够了。」（太六34）这些经文都告诉我们人是有忧虑的，就是主所重用的仆人也不例外；例如保罗，他不是一个没有忧虑的人。他自己告诉我们说：「为众教会挂心的事，天天压在我身上。有谁软弱，我不软弱呢？有谁跌倒，我不焦急呢？」（林后十一28，29）为着被异端影响的信徒，他为他们「再受生产之苦，直到基督成形在他们心里」（加四19）。但保罗也是一个晓得信靠神，将一切忧虑卸给神的人。因此虽身在监牢里，保罗却仍满有喜乐，并劝人要靠主喜乐（腓四４）。
不错，我们难免有诸般的忧虑，但不论我们怎样忧虑，甚至忧虑到胃口不开、不能入眠、神经衰弱……，都无济于事。既然如此，让我们学习在神面前谦卑自己，信靠神，将我们的重担卸给祂，祂就必使我们得享安息（太十一28～30）。因为「我们晓得（神使）万事都互相效力，叫爱神的人得益处。」（罗八28）我们忧虑，因为我们信靠自己过于信靠神。其实神关心我们，过于我们关心我们自己。
圣经没有教我们作个「宿命论」者，凡事逆来顺受。圣经也没有教导我们不负责任，不为前途考虑、计划。我们必须尽我们的责任照顾自己和家人，预备一切所需的。此外，我们也当学习谦卑，服在神大能的手下，将一切的忧虑卸给祂，深信凡事都有主的旨意；若主不允许，我们连一根头发也不致于掉落，因祂顾念我们。
让我们记得，忧虑绝对无济于事，是多余的，反而影响我们的身、心、灵，使我们没有喜乐，精神沮丧，并且影响我们的效率。
「当将你的事交托耶和华，并依靠祂，祂就必成全。」（诗三十七５）
Let's imagine that you bought 500 shares of company XYZ at $90 not too long ago, and the stock has since dropped to $50.75 after a bad earnings announcement. You believe that the worst is over for the company and the stock could bounce back over the next year, but $90 seems like an unreasonable target. Consequently, your only interest is breaking even as quickly as possible instead of selling your position at a substantial loss. (See also: What to do When Your Trade Goes Awry.)
Clifford Scott Asness (/ˈæznəs/; born October 17, 1966) is an American hedge fund manager and the co-founder of AQR Capital Management. According to an April 2020 Forbes profile, Asness' estimated net worth was $2.6 billion.[1]
Asness was born to a Jewish family, in Queens, New York, the son of Carol, who ran a medical education firm, and Barry Asness, an assistant district attorney in Manhattan. His family moved to Roslyn Heights, New York when he was four. He attended the B'nai B'rith Perlman Camp and graduated from Herricks High School.[2]
In 1988, Asness graduated summa cum laude from the University of Pennsylvania, from which he received bachelor's degrees in computer science and finance as part of the Jerome Fisher Program in Management and Technology (M&T).[3] Asness's interest in finance and portfolio management began while he worked a research assistant in the Finance Department at Wharton,[3] where he learned to use "coding computer programs" to analyze markets" and "test economic and financial theories".[4]
In 1989, Asness enrolled at the University of Chicago, where he received his MBA with high honors in 1991 and his PhD in finance in 1994.[5][6] At Chicago, Asness was the Teaching Assistant (TA) for his dissertation adviser, Nobel laureate Eugene Fama[6][3] — who was also Asness' mentor[7] — and the economist, Kenneth French, who were both influential and widely-respected empirical financial economists, had established the foundations of their Fama–French three-factor model in 1992.[8][Notes 1] Fama and French had contrasted value stocks with growth stocks. Since Fama and French's inception of value stocks, "quants have designed algorithms that can scour market data" looking for "factors".[9]
Asness' doctoral dissertation was on "the performance of momentum trading, buying stocks with rising prices". Asness asserted that profits consistently beating market averages were attainable by exploiting both value and momentum. Asness concept of value was referred to in the context of fundamental analysis as a way of assessing the true worth of a security. His use of the concept of momentum referred to betting that the value will continue to go up or down as it did in the recent past. While he did not originate these concepts, Asness was credited with being the first to compile enough empirical evidence across a wide variety of markets to bring the ideas into the academic financial mainstream.[6]
Asness started his career in 1990, when he was 24 and still a PhD student.[7] In the early 1990s, he had left academia, to the regret of his mentor, to become manager of Goldman Sachs Asset Management's (GSAM) "new quantitative research desk." He invited two friends from his cohort at the University of Chicago to join him at GSAM. Together, they began "developing models to evaluate risk in currencies, bonds and entire economies."[4] While the "idea of factors" came from Fama and French, it was first "put into practice" in the late 1990s by Asness, according to The Economist.[9] Asness and his team at GSAM built on Fama and French's idea of factors,[8] and combined their work with insights he had gained from his own PhD research.[3][9] Asness worked as GSAM manager until 1997, when he and some members of the GSAM team, left to start their own quantitative hedge fund.[4][10]
In 1995, Asness persuaded a few partners at Goldman to provide him with an initial US$10-million investment to employ the computer-driven models that his team had developed, to invest in the market.[4][11][12]
When the $10 million initial investment reached $100 million, Goldman opened the fund to the public—the Goldman Sachs Global Alpha Fund.[4] Global Alpha, a systematic trading hedge fund was one of the earliest "quant vehicles" in the industry. The fund became known for high-frequency trading and furthered the careers of Asness and Mark Carhart.[12] Asness and his team used complicated computerized trading models to first locate underpriced equities, bonds, currencies, and commodities and then use short selling to take advantage of upward or downward price momentum.[13] The fund was designed to make money regardless of the direction the market was moving.[13] The Wall Street Journal described Asness and Carhart as "gurus" who managed Global Alpha, a "big, secretive hedge fund"—the "Cadillac of a fleet of alternative investments" that had made millions for Goldman Sachs by 2006.[14] By 2007, at its height, Global Alpha was "one of the biggest and best performing hedge funds in the world" with more than $12 billion assets under management (AUM).[15] Global Alpha was shutdown in the fall of 2011.[11] The quant fund had declined significantly by mid-2008, and continued its decline to $1 billion AUM through 2011.[16]

AQR Founding Managing Principal and Chief Investment Officer Cliff Asness says he thinks equities could be a “scary place” in the event of a US recession. The legendary quant investor also takes a victory lap on “Bloomberg Wealth with David Rubenstein” after AQR’s bet on value finally paid off in 2022 after years of losing to growth stocks.

SA Quantitative Strategy Head
Head of Quantitative Strategies at Seeking Alpha.
Data analysis and interpretation have taken center stage in my career. For my purpose, the interpretation of data is the process of making sense of statistics that have been collected, analyzed, and scored. This skill-set has served as a solid foundation for me to identify trends and make transparent predictions in the course of money management. It has also allowed me to develop user-friendly web-based tools that furnish individuals with the indicators and signals to instantly interpret the strength or weakness of a company's value. Importantly, this expertise has helped me build Wall Street trading desks, launch international hedge funds, and construct a SaaS FinTech investment research company.
Prior to my role at Seeking Alpha as the Head of Quantitative Strategies, I founded a Hedge fund and Asset Management company (Cress Capital Management), I was the Head of International Business Development at Northern Trust, and the majority of my career was at Morgan Stanley running a proprietary trading desk
