Therefore, firms should estimate related sales, cost and other deferred and accrual amounts on an annual basis, and then allocate appropriate amounts to the quarter reported. Under this integral approach, the time series of quarterly earnings must present certain auto-regression structure. This is not surprising given the empirical evidence found in Brown and Rozeff (1979) and numerous followers. However, since there is no prior research examining the data on the domestic market There are some interesting local issues. They are: 1. How well does the market anticipate this auto-regression structure? Does the market under or over react to the structure? 2. Does the integral approach reinforce the auto-regression structure for quarters within the same fiscal year? 3. Is it possible to utilize the knowledge on the structure to earn abnormal returns? 4. Would the auto-regression structure caused by the integral approach affected by other factors, for example, capital intensity and variance of quarterly revenue? This research shall pursue the answers for the above questions.application/pdf48178 bytesapplication/pdfzh-TW國立臺灣大學會計學系暨研究所期中財務報表季盈餘未預期盈餘股票異常報酬interim reportingquarterly earningsunexpected earningscumulative abnormal returns期中財務報告表達方式、季盈餘時間序列結構與股票報酬Integral Approach, Quarterly Earnings, and Stock Returnsreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/18382/1/892416H002013.pdf
