Dispersion trading: Empirical evidence from U.S. options markets

This paper develops empirical evidence on the viability of a form of volatility trading known as “dispersion trading.” The results shed light on the efficiency with which U.S. options markets price volatility.Using end-of-day implied volatilities extracted from equity option prices for the stocks that comprise the S&P 500, the implied volatility of the S&P 500 is computed using a modification of the Markowitz variance equation. This Markowitz-implied volatility is then compared to the implied volatility of the S&P 500 extracted directly from index options on the S&P 500. These contemporaneous measures of implied volatility are then examined for exploitable discrepancies both with and without transaction costs. The study covers the period October 31, 2005 through November 1, 2007.It is shown that, from a trader's perspective, index option implied volatility tended to be more often “rich” and component volatilities tended to be more often “cheap.” Nevertheless, there were times when the opposite was true; suggesting that potential dispersion trades can run in either direction.     

Price discovery in the round-the-clock U.S. Treasury market

We evaluate the efficacy of price discovery in the round-the-clock U.S. Treasury market. Using a comprehensive intraday database, we explore informational role of trades over the 24-hour day. We find that information asymmetry is generally highest in the preopen period and lowest in the postclose period. Information asymmetry in the overnight period is comparable to that in the regular trading period. However, on days with macroeconomic announcements, information asymmetry peaks shortly after the news release at 8:30. Moreover, information asymmetry is higher on Monday morning and higher immediately before than after the open of U.S. Treasury futures trading. Although volume is low after hours and trading cost is relatively high, overnight trading generates significant price discovery. Results suggest that overnight trading activity is an important part of the Treasury price discovery process.     

Informed trading in public debt markets

This study examines the occurrence of informed trading in public debt issued by companies in the United States. I find that earnings surprises are positively associated with bond price changes prior to the release of financial report data to the public, for firms with non‐investment‐grade ratings. Additionally, I find that the effect appears to be driven by firms with publicly traded equity. Evidence further indicates an increase in trading activity during the time window between report period end date and filing date, for firms with larger earnings surprises.     

Foreign holdings of U.S. Treasuries and U.S. Treasury yields

Foreign official holdings of U.S. Treasuries increased from $400 billion in January 1994 to about $3 trillion in June 2010. Most of this growth is accounted for by a handful of emerging market economies that have been running large current account surpluses. These countries are channeling their savings through the official sector, which is then acquiring foreign exchange reserves. Any shift in policy to reduce their current account surpluses or dampen the rate of reserves accumulation would likely slow the pace of foreign official purchases of U.S. Treasuries. Would such a slowing of foreign official purchases of Treasury notes and bonds affect long-term Treasury yields? Most likely yes, and the effects appear to be large. By our estimates, if foreign official inflows into U.S. Treasuries were to decrease in a given month by $100 billion, 5-year Treasury rates would rise by about 40–60 basis points in the short run. But once we allow foreign private investors to react to the yield change induced by the shock to foreign official inflows, the long-run effect is about 20 basis points.     

中美公司债券市场的比较分析

目前,我国公司债券市场的开放程度较低,其发达程度远远落后于股票市场,这在很大程度上制约了我国证券市场的完善,并使得我国资本市场严重失衡;相比之下,美国有着世界上最发达的公司债券市场。本文通过对中国和美国公司债券市场在市场效率、市场特征、定价机制、评级制度等方面的特征进行比较,分析了制约我国公司债券市场发展的主要因素,并相应提出加大我国公司债券市场的开放程度、规范市场主体、完善公司债券评级制度和定价机制等对策建议。     

美国国债收益率曲线倒挂与经济前景展

美国债收益率曲线自2018年底走平到目前出现的倒挂现象引发了市场和政策当局 的广泛关注。本文首先从收益率曲线的基本概念出发,回顾了历史上美国债券收益率曲线和经 济衰退之间的关系。研究发现,美国国债收益率曲线倒挂是预测美国经济衰退的一个较为可 靠的先行指标。然而,由于危机以来美联储货币政策操作模式已发生显著变化,此次收益率曲 线倒挂尽管仍可作为预测美国经济衰退的重要参考指标,但在可靠程度上可能会面临较大不 确定性。同时,又因美国目前的经济基本面总体向好,因此短期内发生经济衰退的可能性并不 大。最后,由于目前特朗普政府政策对美联储货币政策立场存在倒逼机制,因此未来政府政策 的不确定性或将成为左右美国经济走向的关键因素。     

U.S. investors and global equity markets

This study examines international equity flows of U.S. residents to emerging markets in Latin America and Asia and to developed markets in Europe, Canada, and Japan. The major issues addressed are (1) appropriate means of measuring relationships between returns and flows, (2) role of volatility in these relationships, and (3) effects of the Asian crisis. Basic findings include: (1) the information contribution argument is stronger than the feedback trading argument (flows affect returns more than past returns affect flows), (2) volatility of flows and of returns are not of major importance, (3) the Asian crisis effects are important and strongest for Asia followed by developed markets and by Latin America, and (4) regional measures and U.S. returns play significant roles in international equity flows to many countries.     

Information in the U.S. Treasury Term Structure of Interest Rates

We provide evidence of a significant change in the information content of the U.S. Treasury term structure of interest rates over the last 20 years. We apply a regression approach to measure the information in forward interest rates and introduce both a curve fitting method and an alternative data source. We find more information in the recent U.S. Treasury term structure about future interest rates than about expected holding period returns. These results document a significant departure from prior empirical findings.     

Geographical deregulation and competition in U.S. banking markets

The effects of geographical deregulation on competition in banking markets is examined. Using a model that develops an index of competition as proposed by Bresnahan and applied to banking markets by Shaffer, the empirical evidence suggests that geographical deregulation has not had a significant impact on competition. The limited effects of geographical deregulation on competition is consistent with other evidence presented, suggesting that banking markets were already highly competitive. In those states where a significant effect was observed, geographical deregulation increased the degree of competition in some states but had the opposite effect in others.     

The mispricing of U.S. Treasury bonds: a case study

This article documents an apparent pricing anomaly involving9? percent, 30-year Treasury bonds during the months of Mayand June 1986. During this period, the price of the 9?s rosesharply relative to the prices of other long-term Treasury bondsand created a potential arbitrage opportunity. In addition,owners of the 9? bonds were able to borrow at a zero interestrate by pledging their bonds. Detailed examination reveals thatthis relative pricing anomaly cannot be attributed to changesin the level or term structure of interest rates or to differencesbetween the bonds with respect to liquidity, taxation, or duration.     

The U.S. Treasury yield curve: 1961 to the present

The discount function, which determines the value of all future nominal payments, is the most basic building block of finance and is usually inferred from the Treasury yield curve. It is therefore surprising that researchers and practitioners do not have available to them a long history of high-frequency yield curve estimates. This paper fills that void by making public the Treasury yield curve estimates of the Federal Reserve Board at a daily frequency from 1961 to the present. We use a well-known and simple smoothing method that is shown to fit the data very well. The resulting estimates can be used to compute yields or forward rates for any horizon. We hope that the data, which are posted on the website http://www.federalreserve.gov/pubs/feds/2006 and which will be updated quarterly, will provide a benchmark yield curve that will be useful to applied economists.     

中国高额持有美国国债的风险与对策

美国国债曾是公认的最安全的投资品。2001年以来,中国持有的美国国债随外汇储备的快速增长而增加;美国国债规模也随美国"双赤字"的扩大而膨胀。美国的政治生态及美元的霸权特性使得美国的"双赤字"难于控制,美国国债的潜在风险日益显现。中国主要面临退出困难及债权资产实际价值可能大幅缩水的困扰。建议中国利用最大债主的地位制约美国以维护自身权益;同时控制外汇储备增量优化外汇储备结构以掌握风险控制的主动权。     

Macroeconomic Announcements and the Distribution of Price-Endings in the U.S. Treasury Market

We investigate how new information impacts quote clustering in the bond market. We find that clustering, along with quote activity, price volatility and bid-ask spreads, increases sharply in the minutes following releases of macroeconomic news. Each returns to near-normal levels within the hour. Effects are strongest for more liquid on-the-run notes and for the announcements typically associated with substantial information flow. The strong positive comovement of clustering, quote activity, price volatility, and bid-ask spreads supports the conclusion that innovations of these variables are endogenous to the arrival and incorporation of information into prices.     

Competitive inventory management in Treasury markets

We decompose US Treasury bid-ask spreads into inventory, adverse selection and order processing costs by using the fact that inventory trades have different effects on spreads than do proprietary trades. We exploit this asymmetry and develop a technique to identify the three components of the spread in order to test three hypotheses: dealers make larger changes to inventory (1) following macroeconomic announcements (2) at the start and toward the end of the New York trading hours, and (3) when transaction sizes are relatively large. We test these predictions using GovPX data for on-the-run 2-year and 10-year Treasury Notes. All three predictions are supported. We also assess how primary dealers react to the Federal Reserve’s open market operations (OMOs). Our findings reveal interesting intraday patterns in the inventory component for both securities.     

Income shifting and U.S. international trade in goods statistics

Intrafirm trade represents greater than one-third of total U.S. international trade in goods. Since these are not arm’s-length transactions, trade policymakers have voiced concerns that income shifting may distort international trade in goods statistics through the manipulation of transfer prices. Using country-level data on intrafirm exports and imports, we estimate a path analysis that simultaneously tests how and to what extent tax-motivated transfer pricing and real investment decisions affect intrafirm trade in goods statistics. Contrary to speculation, we do not find an economically significant relation between transfer pricing and intrafirm trade in goods statistics. In contrast, we find that tax-motivated location decisions create a 21 (20) percent or $819.7 ($927.1) million difference in mean intrafirm exports (imports) between the U.S. and a low- and high-tax country. This study provides trade policymakers with relevant information about the extent to which real investment decisions and accounting manipulations affect intrafirm trade in goods statistics and contributes to the international trade and income shifting literatures.     

Liquidity,Reconstitution, and the Value of U.S. Treasury Strips

An apparent pricing anomaly exists in the market for U.S. Treasury strips: zero-coupon strips created from principal payments typically trade at significantly higher prices than otherwise identical zero-coupon strips created from coupon payments. In addition to documenting this phenomenon, this study demonstrates that differences in liquidity and differences in reconstitution characteristics explain much of this price variation.     

Information flow between the stock and option markets: Where do informed traders trade?

This paper investigates the flow of information between the equity and options markets. We argue that informed traders, in deciding where to place their trades, are not entirely indifferent to option moneyness, degree of information asymmetry, and option liquidity. Unlike some previous studies that find information to flow unilaterally from equity to options markets, we control for the above factors and discover feedback relations between trades in out-of-the-money (OTM) options and the underlying equities. The finding is consistent with the pooling equilibrium hypothesis, which asserts that informed traders trade in both the equity and options markets. Some informed traders are probably attracted to the out-of-the money options because of their higher liquidity, lower premiums, and higher delta-to-premium ratios, hence, lending support to the liquidity and leverage hypothesis.     

Liquidity,Maturity, and the Yields on U.S. Treasury Securities

The effects of asset liquidity on expected returns for assets with infinite maturities (stocks) are examined for bonds (Treasury notes and bills with matched maturities of less than 6 months). The yield to maturity is higher on notes, which have lower liquidity. The yield differential between notes and bills is a decreasing and convex function of the time to maturity. The results provide a robust confirmation of the liquidity effect in asset pricing.     

The Price of Future Liquidity: Time-Varying Liquidity in the U.S. Treasury Market

This paper examines the price differences between very liquid on-the-run U.S. Treasury securities and less liquid off-the-run securities over the on/off cycle. Comparing pairs of securities in time-series regressions allows us to disregard any fixed cross-sectional differences between securities. Also, since the liquidity of Treasury notes varies predictably over time, we can distinguish between current and future liquidity.We compare a variety of (microstructure-based) direct measures of liquidity to compare their effects on prices.We show that the liquidity premium depends primarily on the amount of remaining future liquidity.
