Impact of Retail Traders on Market Structure
The explosive growth in options trading has increased market volume but has not meaningfully changed market structure. Retail traders selling premium can influence short-term price action, but this is not enough to alter the overall market structure. The key mechanism is that while retail participation creates more volume, it does not lead to sustained volatility increases, which would be a sign of structural change. The practical implication is that market structure remains largely unchanged despite increased retail participation.
