Everybody Wants The 4-Day Work Week, But Could Wall Street Ever Make It Happen?

Full quote provided:

"In my opinion it's very unlikely for the stock exchanges to move to a 4 day week in terms of trading hours. Reducing the number of trading days would constrain liquidity and lead to increased volatility. This is not an outcome that most financial professionals would want to experiment with. Paradoxically, extending the trading hours to 24/7 might have the same effect. For any exchange, it's best to have the most professional traders to be present at the same time."
