The study analyzed the performance of IT firms after their initial public offerings (IPOs) by looking at underpricing and investor attention. They found that investor interest in IT companies increased compared to other industries, leading to more underpricing for IT firms. Increased investor attention positively affected the performance of both IT and non-IT companies post-IPO, with a stronger impact when underpricing was higher. Over the long term, the positive effects of underpricing and investor attention on non-IT companies weakened, while for IT companies, these effects remained significant. This suggests that underpricing and early investor interest have a lasting impact on the actual value of IT firms due to factors like network effects and industry structure.
