Analyst coverage: Does the listing location really matter?
研究发现上市地点显著影响分析师覆盖数量，主板（FTSE350）比创业板（AIM）吸引更多分析师，且上市要求对创业板公司影响更大。
Using a count panel regression method, we find that the listing location really does matter as stocks listed on the main board (FTSE350) rather than the junior market (AIM) attract more analyst coverage than can be explained by existing factors, even when we control for listing requirements and the type of cross-listing. We also find that listing requirements have a significantly greater impact on the number of analysts following AIM companies rather than their FTSE350 counterparts. Moreover, pooling stocks from different listing locations can conceal additional differences in the determinates of analyst services for the main board and junior markets. For example, cross-listing on a stock exchange increases analysts coverage for FTSE350 stocks but not AIM stocks and listing on less transparent trading venues such as over the counter and alternative trading systems (dark pools) decreases analyst coverage, especially for AIM stocks.
