Most quant positions in finance require advanced degrees, with a significant percentage of professionals holding PhDs or master's degrees in technical fields. Programming skills, particularly in languages like C++ and MATLAB, are essential for these roles, often overshadowing traditional finance knowledge. Pursuing a PhD in physics is discouraged for those primarily interested in finance, as it may not provide versatile career options. Entry-level quant roles are heavily programming-focused, and many individuals in these positions do not transition to high-paying trader roles. Overall, a strong background in computer science or engineering is often preferred over a physics degree for aspiring quants.
