Understanding the market effects of Olympic host announcements is popular in academic research. Contrary to prior studies, announcing PyeongChang as the 2018 host had a positive effect on South Korea's Stock Market, with conservative estimates suggesting a peak of +3.8% during the 15 trading days post announcement (an increase equivalent to $34.962 billion). The degree to which firms benefitted varied by industry and lifecycle stage. Older and lower-growth financial and information technology firms saw larger abnormal returns compared to other firms. These findings suggest that academics and investors pay greater attention to idiosyncratic price adjustments to systematic market shocks.

了解奥运会主办方公告的市场影响在学术研究中很受欢迎。与之前的研究相反，宣布平昌为 2018 年东道主对韩国股市产生了积极影响，保守估计表明在宣布后的 15 个交易日内达到了 +3.8% 的峰值（增加了 349.62 亿美元）。公司受益的程度因行业和生命周期阶段而异。与其他公司相比，老牌和低增长的金融和信息技术公司的异常回报更大。这些发现表明，学术界和投资者更加关注对系统性市场冲击的特殊价格调整。
