Purpose: This study investigates the relationship between earnings forecasts estimated from a cross-sectional earnings forecast model and firm characteristics such as firm size, sales volatility, and earnings volatility. Research design, data and methodology: The association between earnings forecasts and the aforementioned firm characteristics is examined using 214 firm-year observations with analyst following and 848 firm-year observations without analyst following for the period of 2011-2019. I estimate future earnings using a cross-sectional earnings forecast model, and then compare these model-based earnings forecasts with analysts' earnings forecasts in terms of forecast bias and forecast accuracy. The earnings forecast bias and accuracy are regressed on firm size, sales volatility, and earnings volatility. Results: For a sample with analyst following, I find that the model-based earnings forecasts are more accurate as the firm size is larger, whereas the analysts' earnings forecasts are less biased and more accurate as the firm size is larger. However, for a sample without analyst following, I find that the model-based earnings forecasts are more pessimistic and less accurate as firms' past earnings are more volatile. Conclusions: Although model-based earnings forecasts are useful for evaluating firms without analyst following, their accuracy depends on the firms' earnings volatility.

재무분석가의 투자전략 보고서는 전문가의 금융정보 분석으로 사람들간의 금융 정보 격차를 줄일 수 있게 만들어 줄 수 있다. 하지만 여러 다른 인센티브로 말미암아 투자전략 보고서는 왜곡의 소지가 있을 수 있다. 만약, 투자전략 보고서 제목만으로 예측에 미치는 영향을 파악할 수 있다면, 예측력이 높은 투자전략 보고서를 분별할 수 있게 된다. 이에 본 연구는 재무분석가의 투자전략 보고서의 제목과 예측의 관계를 파악하려 한다. 텍스트 마이닝을 사용하여, 국내 재무분석가의 투자전략 보고서 제목으로부터 연구의 중요변수인 투자의견을 추출하고 모형을 구축하여 재무분석가의 예측 정확도와 예측 달성도를 측정하였다. 분석 결과, 강한 매수의견과 매도의견이 제목에 있을수록 재무분석가의 예측 정확도와 예측 달성도가 높아짐을 검증하였다. 본 연구 결과가 투자자에게 더 정확한 투자전략 보고서를 판단하는 기준를 제시하기를 바라고 빅데이터를 통한 분석 연구에 시사점을 주길 기대한다.

This study focuses on presenting the IT program module provided by BKLS measure in order to solve the problem of capital cost due to information asymmetry of external investors and corporate executives. Barron at al(1998) set up a BKLS measure to guide the market by intermediate analysts. The BKLS measure was measured by using the changes in the analyst forecast dispersion and analyst mean forecast error squared. This study suggests a model of the algorithm that the BKLS measure can be provided to all investors immediately by IT program in order to deliver the meaningful value in the domestic capital market as measured. This is a method of generating and analyzing real-time or non-real-time prediction models by transferring the predicted estimates delivered to the Big Data Log Analysis System through the statistical DB to the statistical forecasting engine. Because BKLS measure is not carried out in a concrete method, it is practically very difficult to estimate the BKLS measure. It is expected that the BKLS measure of Barron at al(1998) introduced in this study and the model of IT module provided in real time will be the starting point for the follow-up study for the introduction and realization of IT technology in the future.

Analysts' forecasts are important for providing useful guidance to investors, especially individual or small investors, and therefore it becomes critical to identify the elements which can potentially increase errors in analysts' forecasts. This study investigates potential factors which can lead to errors in forecasting by analysts, specifically in terms of the level and attributes of corporate earnings. Utilizing a sample of firms listed on the Korean stock markets, this study provides evidence that firms with more volatile and unpredictable earnings feature less accurate analyst forecasts. This study fills a void in the literature by conducting empirical tests for earnings attributes in terms of volatility and unpredictability that could potentially undermine the forecast accuracy. The negative association between the quality of earnings and forecast accuracy is more pronounced for firms with negative net income values. Additional analysis demonstrates that forecast accuracy is significantly lower for the fourth quarter than for other fiscal quarters and that fourth quarter earnings tend to be more volatile and unpredictable. This study contributes to the literature by providing new empirical evidence regarding the comprehensive effects of earnings quality and level on analysts' forecasting accuracy and further suggests potential factors contributing to the fourth quarter anomaly in analyst forecasts in terms of earnings attributes.

본 연구에서는 2000년부터 2002년까지의 기간에서 국내 외의 재무분석가들이 1999년$\sim$2003년까지의 각 연도별 연간 매출액, 영업이익과 순이익에 대하여 발표한 예측치를 대상으로 하여 재무분석가들이 기업실적을 얼마나 정확하게 예측하며, 예측치를 수정할 때 어떤 체계적인 경향을 보이며, 기업실적을 예측할 때 전년도의 실적변화에 대해 어떤 반응을 보이는지를 분석하는데 목적을 두었다. 이러한 분석목적을 달성하기 위하여 재무분석가별, 예측년도별, 전년도의 기업실적 변화별로 표본을 각각 분류하여 재무분석가별 예측의 정확성, 합의예측치의 상대적 정확성, 예측치의 수정패턴 및 예상 밖의 전년도 실적변화에 대한 반응을 분석하였다. 본 연구에서 발견된 분석결과를 요약하면 다음과 같다. 첫째, 매출액, 영업이익과 순이익의 표준예측오차가 모두 통계적으로 유의적인 음(-)의 값을 보임으로써 재무분석가들이 기업실적을 상향 편의적으로 예측하는 경향이 있음을 발견하였다. 둘째, 국내. 외 재무분석가의 예측정확성을 비교한 분석에서 국내 재무분석가들이 국외 재무분석가들에 비해 상대적으로 정확한 예측을 하고 있음을 발견하였다. 셋째, 예측시점별로 측정한 평균표준예측오차에 대한 분석에서는 예측시점이 기업실적의 발표시점에 가까워질수록 예측의 정확성이 높아짐을 발견하였다. 넷째, 개별재무분석가와 비교할 때, 합의예측치의 정확성이 상대적으로 떨어지는 것으로 나타났으며, 합의 예측치를 추정할 때 평균보다 중위값을 이용하여 추정한 경우 예측오차를 줄일 수 있는 것으로 나타났다. 다섯째, 재무분석가들이 기업실적을 과대 예측한 다음 예측치를 하향 수정하는 것으로 나타났으나 체계적이지 않음을 발견할 수 있었다. 즉 재무분석가들은 전년도의 기업실적에 따라 예측치를 상향 또는 하향 수정하는 것으로 나타났다. 여섯째, 재무분석가들은 예측활동을 수행하는 과정에서 전년도의 매출액 변화에 대하여 과대 반응하는 한편 전년도의 영업이익과 순이익 변화에 대하여 과소 반응함을 발견할 수 있었다. 일곱째, 재무분석가들의 예측편의를 보다 정확하게 분석하기 위하여 정보변수인 전년기업실적 변수를 예상된 실적변화와 예상치 못한 실적변화로 분류하여 Easterwood-Nutt(1999)모형을 이용해 분석한 결과 세 개의 기업실적변수(매출액, 영업이익과 순이익)모두의 예상치 못한 전년실적변화에 대해 재무분석가들이 과대 예측하는 것이 아니라 낙관적 예측을 수행하는 경향이 있음을 발견할 수 있었다.

This paper attempts to measure the impact of non-financial factors including analyst practices and broker resources on performance of sell side research. Results reveal that these non-financial factors have a measurable impact on performance of target price forecasts. Number of pages written by an analyst (surrogate for analyst practice) is significantly and directly linked with target price accuracy indicating a more elaborate analyst produces better target price forecasts. Analyst compensation (surrogate for broker resource) is significantly and inversely linked with target price accuracy. Out performance by analysts working with lower paying firms is possibly associated with motivation to migrate to higher paying broking firms. The study finds that employing more number of analysts per research report has no significant impact on target price accuracy -negative coefficient indicates that team work may not result in better target price forecasts. Though insignificant, long term forecast horizon negatively affects target price accuracy while stock volatility improves target price accuracy.

This study examines whether auditors restrain the analysts' opportunistic behavior as reviewing the companies' interim reports. Analysts' forecasts show a walkdown pattern in which their optimism has decreased as the earnings announcement date has approached. At the beginning of the year, there is a lack of high-quality benchmark information that enables information users to judge the accuracy of analyst's earnings forecasts. Thus, early in the year, analysts are highly inspired to disseminate optimistic forecasts in order to gain manager's favor. In this study, we examine adequate benchmarks prevent analysts from disclosing optimistically biased forecasts. We conjecture that auditors' efforts might mitigate analysts' walkdown pattern. To test this hypothesis, we use data from Korea, where it is mandatory to disclose auditor's review hours. We find that the analyst forecast's walkdown decreases with the ratio as well as the number of audit hours. It implies that an auditor's effort in reviewing interim financial information has a monitoring function that reduces analysts' opportunistic optimism at the beginning of the year. We conjecture that the tendency will be more pronounced when BIG4 auditors review the interim reports. Consistent with the prediction, BIG4 auditors' interim review effort is more effective in suppressing the analysts' walkdown.

Purpose - The international market provides a growth momentum for firms by allowing them to tap into a new market. Given information asymmetry between firms and financial analysts, firms' international growth can be perceived as a higher business prospect by analysts. This paper explores the possibility of analysts' over-emphasis on foreign income growth in predicting earnings. Research design, data, and methodology - We utilize a sample of U.S. firms to test the relationship between foreign income growth and analysts' forecast optimism. Our sample of publicly listed and traded U.S. firms between 1976 and 2016 consists of 6,120 firm-year observations. Results - Empirical analyses show that firms that show higher international growth in earnings are likely to face forecast inaccuracy by financial analysts. From the perspective of firms, their earnings are less than what analysts forecasted. Contrary to our prediction on the moderating effect of innovative capabilities, optimistic bias is not intensified - rather, it is reduced - when firms have higher innovative capabilities. Conclusions - Our results imply that while analysts favor firms with higher international growth, innovative capability on the international market places additional risks to firms' operation.
