assessing the market’s use of analyst estimates and quarterly earnings announcements

Assessing the Market’s Use of Analyst Estimates and Quarterly Earnings Announcements

Sam Lim

To cover Continue exploring impact of

beating/missing/meeting analyst estimates on price.

Issues remaining from last presentation Sampling frequency had very significant impact on

results Accounting for dispersion—last time used one

interaction term Left out analysis of overnight returns/intraday

returns Any systematic patterns? Conclusion

Problem from last time with sampling frequency

Previously, saw that sampling at 10 minutes and 15 minutes gives contradictory results

Sub-sampling provides consistencyWal-Mart sub-sampled at 15 minutes

Firms with 7 or more quarterly earnings misses: 12 firms

Firms with 7 or more quarterly earnings meeting of expectations: 14 firms

All firms: 30 firms

Conclusion Unfortunately, no nice systematic pattern, but can make some rough

generalizations. Sub-sampling helps to bring more consistent results. At very least, can back up using a different method (HAR-RV) the

research done by Beaver (1968) and Landsman and Maydew (2002). An earnings surprise in general is strongly correlated with overnight

returns in the same direction, not so much intraday returns. Market adjusts fairly quickly to news.

Research corroborates idea that negative news has larger impact than positive news. Of the 13 firms where both beat and miss days were significantly correlated with volatility, 10 of them had larger coefficients on miss days. Of the 17 firms where both days were sig. correlated with overnight returns, 15 had larger coefficients on miss days.

The results seem to indicate that market responds more to fact that there is a negative or positive surprise than the actual magnitude (corroborates research by Kinney et al. in 2002).

Dispersion – got lucky with McDonald’s, is significant with some firms but not all.
