Can Analysts Analyze Mergers?
研究发现，并购后继续跟踪合并公司的目标方分析师比收购方分析师能提供更准确的盈利预测和更乐观的股票推荐，且目标方分析师覆盖比例越高，合并公司未来经营和长期股票表现越好。
After the completion of a merger and acquisition (M&A) transaction, the target firm is delisted, but some analysts who covered it retain coverage of the merged firm. We hypothesize that this decision is based on two factors: the analyst's ability to cover the merged firm and his or her assessment of the M&A deal. Consistent with these hypotheses, we find that the remaining target analysts provide more accurate earnings forecasts and more optimistic stock recommendations and growth forecasts for the merged firms than do the remaining acquirer analysts. We also find that a higher percentage of target analysts choosing to cover the merged firm is associated with better operating and long-term stock performance of that firm, but we do not find this relation with acquirer analysts. Our results extend the literature by showing that target analysts' coverage decisions reveal valuable information about a merged firm's future performance.
