I’m trying to better understand the more “technical” drivers behind sudden market moves.
I’m already familiar with things like month-end fixing, CTA positioning/flows, and options expirations (OPEX), but I feel like there are other factors that can also cause sharp rallies or selloffs.
What are some other technical or flow-driven reasons markets can move quickly? For example, things related to dealer positioning, liquidity, rebalancing, or anything similar.
Would appreciate insights or examples from people who follow this closely.
