Macroeconomic surprises and short-term<br />

behaviour <strong>in</strong> bond futures<br />

Abstract This paper analyses the effect <strong>of</strong> macroeconomic news on the price <strong>of</strong><br />

the ten year USATreasure bond future. We consider 15 fundamentals and we analyse<br />

the effect <strong>of</strong> their forecast<strong>in</strong>g errors conditional upon their sign and the momentum<br />

<strong>of</strong> the bus<strong>in</strong>ess cycle. To obta<strong>in</strong> a smooth effect <strong>of</strong> the news arrival we estimate a<br />

Polynomial Distributed Lag model. Us<strong>in</strong>g 10 m<strong>in</strong>utes sampled data dur<strong>in</strong>g 9 years,<br />

we conclude that 1) releases affect the bond future for only few hours, 2) their effect<br />

depends on the sign <strong>of</strong> the forecast error, 3) their effect also depends on the<br />

bus<strong>in</strong>ess cycle and 4) the timel<strong>in</strong>ess <strong>of</strong> the releases is significant.<br />

1 Introduction<br />

Researchers and security price analysts are <strong>in</strong> fundamental disagreement about<br />

the causes <strong>of</strong> price movements. Both groups, economic theorists and econometrics<br />

practitioners, have produced a plethora <strong>of</strong> articles expla<strong>in</strong><strong>in</strong>g the reasons for<br />

volatility, trends, cluster<strong>in</strong>g, long memory and other price movements. But one<br />

phenomenon <strong>in</strong> which they express common agreement is that when prices are<br />

sampled at a sufficiently <strong>high</strong> <strong>frequency</strong> (i.e. at least <strong>in</strong>tradaily), short term movements<br />

can partly be attributed to news arrivals. In particular, to macroeconomic<br />

announcements.<br />
