The disadvantages of after-hours (trading/work) include increased volatility and risk, due to lower liquidity (fewer buyers/sellers) and wider bid-ask spreads, making trades harder and more expensive to execute at desired prices. For work, after-hours shifts lead to potential fatigue, higher error rates, lower productivity, and work-life balance issues, as well as regulatory/brokerage restrictions on trading, limited access to all stocks, and potential for price gaps or manipulated movements.

What are the downsides of after-hours trading?

If you're seeking to buy or sell securities during extended hours, you might find comparatively fewer counterparties, making it more difficult to execute a trade.
