The business and financial world has seen accelerating change in recent years. Advances in technology and digitization have led to more sudden and unpredictable changes, making vigorous and swift decisions and strategies especially critical for organizations and individuals. This dissertation aims to answer questions about how to deal with uncertainties in a volatile investment environment from an organizational or individual perspective. Several related research questions are parsed with separate analytical methods. The first essay introduces a well-developed notion of resilience into the financial portfolio management area and proposes a resilience-based portfolio management framework in a highly fluctuating market. The second essay proposes a theoretical framework to study the value propositions of a business in an innovation environment. The last essay examines the relationship between cryptocurrency market volatility and social media activities by applying textual analysis techniques and social media analytics with data mining. A socio-psychological group identification method was applied. These studies could help to advance the understanding of the market dynamics in the world that is changing faster than ever with data-driven investment decisions in the era of disruptive financial technology.
