Volatility creates a short list of genuinely useful actions, and a much longer list of tempting ones.
Sharp drawdowns invite activity. Most of it subtracts value, but a few moves are worth making precisely when markets are unsettled.
Loss harvesting, rebalancing back to policy weights, and accelerating planned conversions all work better at lower prices.
The common thread is that each was already part of the plan. Volatility changes the timing, not the strategy.
