Thesis

Market Reaction to Corporate disclosures

The Wall Street Journal reports a significant increase in investors’ interest in Bitcoin and Blockchain technology because of the sharp increase in Bitcoin price in 2017. Companies that have been involved in this type of popular technology grow rapidly including increased share price and attractiveness to investors. Apart from Bitcoin, a variety of new technologies emerge each year to drive the development of industries and society. My thesis investigates the market reactions to companies’ disclosures at different development stages (during innovation trigger and the peak of inflated expectations) of emerging technologies. In detail, what is the investor reaction to corporate disclosures about emerging technologies? Do investors react differently to technology that is at different stages of development? Will there be a difference between short-term and long-term reactions? In addition, my thesis delves into the frequency of disclosures, the timing and whether the type of technology will lead to different market reactions. Regarding disclosure behaviour, companies have different motivations to make voluntary disclosures. Therefore, my thesis also investigates the real benefits of these disclosures for companies, such as the cost of equity capital, profitability, etc. Through a custom dictionary, the thesis analysed the content of more than 800,000 8-K filings from US companies since 2010 to find emerging-technologies related information.
