As Investors Tolerate More and More Risk, Bears Start to Emerge
In competitive markets, investors take big risks in a hunt for big rewards. These days, however, taking those gambles isn't so lucrative, even when the bets work.
That reality hasn't damped investor interest in riskier trades -- though that may be changing.
Behind the continued appetite for risk has been a "What, me worry?" attitude among investors. After all, they argue, the world seems a safer place today than it was a few years ago: Inflation seems contained in most major economies. Credit-rating upgrades outnumber downgrades. Companies around the globe are flush with cash and are starting to snap each other up.
"People have become complacent," says Ron Papanek , a New York-based strategist with RiskMetrics Group, a risk-analytics firm. "They're very comfortable with the economic environment. They're comfortable with stocks, comfortable with the long end of the fixed-income market, comfortable with credit markets."
Yet despite the smooth surface of the investing landscape, troubling elements lurk. And some investors have started shifting away from riskier assets. A couple of recent bumps in the bond and derivatives markets have some investors wondering whether the smooth ride may be coming to an end -- though others have been calling for such a turn for more than a year.
"For us, the fact that all the risky assets have outperformed is a sign of worry," says Robert Lind, head of economics and strategy at ABN Amro in London.
The cautious cite rising interest rates and high commodity prices, which could spur inflationary pressures. Currency markets recently wobbled on news that the South Korean central bank and Japan's Ministry of Finance might diversify away from holding U.S. dollars. And political risks haven't evaporated: Consider North Korea's recent nuclear taunts and the persistent insurgency in Iraq.
Nevertheless, voices of caution are few. For the most part, investors keep charging into increasingly risky assets as never before, even as the returns on those assets diminish. Since many of the world's central bankers started ratcheting down interest rates in 2001, investors have been on the hunt for yield.
With safer government bonds paying tiny interest rates, that has meant a plunge into riskier places, such as Brazil, Russia and developing markets in Asia. Dissatisfied with puny returns from high-quality bonds, investors have gobbled up "junk" bonds, debt issued by companies with questionable financial strength. The appetite for taking on more risk also has contributed to the proliferation of hedge funds promising higher returns through intricate trading strategies.
In the short run, these moves boosted portfolio returns. At the same time, they have increased the number of active traders exchanging risky assets, spread investment risk more widely across markets and reduced price volatility. The result of that activity: a rather calm market among riskier assets.
But there is a debate about whether today's market conditions are sustainable.
In congressional testimony last month, Federal Reserve Chairman Alan Greenspan raised a red flag, saying financial-market participants "seem very confident about the future and...quite willing to bear risk." Mr. Greenspan pointed in particular to so-called implied stock-market volatility, which refers to investors' expectations about the possibility of sudden, sharp market movements as measured by an index that trades on the Chicago Board Options Exchange. Over the past two years, the index, called the VIX, has moved in one general direction: down, suggesting investors see smooth sailing ahead.
These historically low levels of implied stock-market volatility are particularly important, and hard to explain, because the VIX tends to move back to its historical average and to follow the direction of interest rates, says Markus Rosgen, Asian regional head of strategy for Citigroup in Hong Kong. Mr. Rosgen calculates that on a 50-month moving average, the VIX trades around 22; as of Friday, the VIX was trading at 12.8 on the CBOE. Big VIX spikes more often are correlated to bear than bull markets.
To be sure, part of the explanation for this state of affairs may be that there are fundamental, structural changes taking place in the markets and broader economy.
The increasing transparency of global markets, rising dividend yields that help to cushion stock-price moves, and the explosion of hedge funds that leap on arbitrage opportunities also may represent basic changes to markets, helping to keep volatility below historical levels for the longer term.
Meanwhile, investment banks have chipped in by selling bucketfuls of complex products that allow investors to insure against sudden stock-price moves -- and, in the process, further slice up and distribute risk across the market.
All of this seeming diminishment of risk worries analysts. But they are hard-pressed to identify what could shake the calm markets.
"It's exactly times like these when things happen and people are least prepared for it," says Alvin Lee, who manages RiskMetric's Asian-Pacific business.
Which is why some investors aren't waiting to find out.
"Markets have gone on for two great years, and does it really pay me to take a lot more risk? I'm of the opinion that it doesn't," says Samir Mehta, the chief investment officer of fund company Lloyd George Management in Hong Kong. Over the course of 2004, Mr. Mehta's funds unloaded steel, petrochemical and shipping companies in favor of more stable high-dividend-yielding stocks. "I'm telling investors to think of 2005 as a year with lower returns and to focus on preservation of capital."
Friday's Market Activity
The Dow Jones Industrial Average slipped back into negative territory for the year, as investors focused on inflation and interest-rate worries.
The Dow industrials dropped 77.15 points to 10774.36, ending the week down 166.19 points, or 1.5%, after having closed at a 3?-year high and within 60 points of 11000 the previous week. The Dow is down 8.65, or 0.1%, year to date.
The Nasdaq Composite Index lost 18.12 points, or 0.88%, to 2041.60, and 29.01, or 1.4%, for the week. The Nasdaq is down 133.84, or 6.2%, for the year.
Chip giant Intel raised the lower end of its revenue forecast and boosted its profit margin for the first quarter. After opening higher Friday, the stock joined the broader selloff, becoming one of the Dow industrials' worst performers, down 65 cents, or 2.6%, to $24.20.
Kmart Holding climbed $14.89, or 13%, to $127 on the Nasdaq Stock Market, after UBS raised its rating on the discount retailer's stock to "buy" from "neutral," saying that the company's pending merger with Sears, Roebuck will be able to "generate significant cash flow through asset sales, cross-selling of proprietary brands, and cost savings." Sears was up $4.20, or 7.9%, at $57.56.
投资者依然热衷于高风险投资
在竞争性的市场中,投资者承担高风险以追求高回报。但现在即使投资选择正确,此类交易的回报似乎也不那么诱人了。
不过,这并未降低投资者对高风险交易的兴趣。
支撑风险偏好的是投资者那种“有什么可担心?”的心态。他们认为,毕竟,现在的世界看上去要比几年前安全多了:主要经济体的通货膨胀水平似乎大都在可控制的范围内。信用评级的上调多于下调。全球许多公司现金充足,掀起了并购浪潮。在政局方面,美国、亚洲和伊拉克的大选都已经完成,不确定性也下降了。
风险分析公司RiskMetrics Group驻纽约的策略师帕帕纳克(Ron Papanek)表示,人们对目前的经济环境感到满意,对股市、长期固定收益证券市场以及信用市场均表满意。
但在这貌似风平浪静的下面,不安定因素依然存在。一些投资者已开始回避高风险资产。债市和衍生产品市场近来的几次震荡让一些投资者猜测这种平静行将结束,其实这种猜测一年多以前就已经存在了。
“在我们看来,所有高风险资产的市场表现均强于大盘是令人担忧的迹象,”荷兰银行(ABN AMRO)驻伦敦的经济和策略主管林德(Robert Lind)表示。
持谨慎态度的人列举了利率上升和大宗商品价格居高不下等不利因素,这些因素会导致通货膨胀压力加大。近来,韩国央行和日本财务省有可能降低美元在其外汇储备中所占比重的消息,让外汇市场摇摆不定。政治风险也未消失:如朝鲜近来的核叫嚣以及伊拉克持续不断的叛乱。而且,爆发企业危机、出现公共健康危机或发生恐怖袭击等的可能性也依然存在。
不管怎样,谨慎的声音不多。大多数投资者仍在以前所未有的热情杀入高风险资产市场,虽然这些资产的投资回报率呈现下降。自2001年全球许多央行开始逐步降息以来,投资者们一直在追求高收益率。
由于低风险的国债市场普遍收益率微薄,许多投资者一头扎进了巴西、俄罗斯和亚洲发展中国家的国债市场。由于不满意高质量债券的低回报,投资者大量买入“垃圾债券”,即财务健康有问题的公司发行的债券。风险嗜好也推动了对冲基金的泛滥;对冲基金往往通过复杂的交易策略承诺较高的回报。
短期内,这些交易提高了投资组合的回报率,并吸引更多交易员活跃从事高风险资产的交易,将投资风险分散在更多市场间,降低了价格波动性。其结果是高风险资产市场表现相当平稳。
但慢慢地有了一种争论,即目前平稳的市场状况是否可以持续。一个挥之不去的担忧是:一个单一事件是否会打破目前微妙的平衡,导致垃圾债券、对冲基金等各种投资资产出现恐慌性的抛售。
美国联邦储备委员会(Federal Reserve, 简称Fed)主席格林斯潘(Alan Greenspan)上个月在国会作证时亮起了一盏红灯,他说,“金融市场的参与者们似乎对未来非常有信心......非常愿意承担风险。”
格林斯潘特别指出了所谓的股市引伸波幅,即投资者对市场突然发生急剧波动之可能性的预期,衡量指标是在芝加哥期权交易所(Chicago Board Option Exchange)交易的VIX指数。过去两年,VIX指数呈现单向下跌,说明投资者预计未来市场走势平稳。欧洲和亚洲的交易者们称,他们的市场追随美国的走势。
花旗集团(Citigroup)驻香港的亚洲地区战略主管罗斯根(Markus Rosgen)表示,股市引伸波幅的历史低水平非常重要,因为VIX指数具有回到历史平均水平和遵循利率走势的趋势。罗斯根计算,VIX指数的50个月移动平均值为22左右;截至上周五,VIX指数在芝加哥期权交易所报12.8。VIX指数的大幅攀升通常与熊市联系在一起,而不是牛市。
债市的波动性似乎也不大,因为投资者感觉在预测利率走势(基本保持不变)方面似乎越来越得心应手。RiskMetrics的数据显示,过去两年,2年期美国国债的3个月引伸波幅下降了约72%,10年期国债的3个月引伸波幅下降了38%。美国国债市场引申波幅的下降鼓励投资者大批涌入垃圾债券。
当然,这种状态一定程度上或许可以以金融市场和宏观经济发生了根本性和结构性的变化来解释。苏格兰爱丁堡Standard Life Investments的米列根(Andrew Milligan)指出,以经济增长和通货膨胀趋势而言,自20世纪60年代以来商业周期从未如此平静。
“这是一个非常有趣的状态,”米列根表示,“它可能持续多年,也可能几个月后就宣告结束。”
全球市场的透明度日益提高,股息收益率的上升以及对冲基金数量的爆炸式增长,可能也代表著市场的基本面改变,这有助于将引申波幅在中长期内维持于历史低点。
“对冲基金数量的大幅增加有显著的影响,”美林(Merrill Lynch)驻香港的环太平洋股票衍生品研究联合主管瑞斯(Arik Reiss)表示,“他们的交易大大减弱了市场的波动性。”
与此同时,投资银行也参与其中,出售大量针对股价波动向投资者提供保护的复杂产品,在这个过程中市场被进一步分割,风险更加分散。这些所谓的结构性产品也降低了市场波动性。但随著利率上升,银行家们预计这些产品的受欢迎程度将下降,随著这些产品被抛出,市场的波动性将上升。
