The financial landscape of the 21st century is increasingly dominated by Hight-Growth Technology (HGT)
firms whose market valuations frequently detach from traditional fundamentals, driven instead by
technological optionality, speculative narratives and extreme volatility regimes. During the 21st Century the
market has experienced an unprecedented and disanalogous to previous centuries growth in Technology,
this has created a myriad of investment opportunities but also investment traps leading to sunk investments
and dead ends.
This thesis provides a rigorous quantitative analysis of the risk structure embedded within a high-risk share
investment using the Tesla, Inc. equity as an example due to being a quintessential high-beta, high-growth
technology (HGT) asset. Utilizing Generalized Autoregressive Conditional Heteroskedasticity (GARCH
(1,1)) and descriptive statistical analysis, the study supports the core hypothesis: the pronounced decline in
Tesla’s share price post- Q 4 2022 was an amplified consequence of its inherent high systematic risk, while
its persistent structural risk is defined by severe asymmetric downside return dynamics.
