Intel Trump often releases news that affects the market on weekends, and Wall Street traders generally choose Friday as a safe haven

BlockBeats News: On May 16th, according to analysis by Barclays Plc, the demand for portfolio adjustments on Friday was sufficient to increase the cost of trading high-grade corporate bonds by 31% compared to other times. Trzcinka from Impax said, "We did notice more market activity on Friday, you don't know what will happen over the weekend In recent years, Friday used to be the cheapest day of the week for buying and selling bonds, but now the situation has reversed. Barclays analysts Zornitsa Todorova and Andrea Diaz Lafuente wrote in a report that in March and April, investment grade corporate bond trading volume on the last trading day of each week accounted for 18% of weekly trading volume, up from 16% in 2023 and 2024. Since Trump returned to the White House, there has been a broader jump in market activity, with his often unexpected policy decisions on tariffs, immigration, and foreign affairs disrupting the economic outlook, and Friday's accelerated pace being part of it. According to analysis by Athanasios Psarofagis, an analyst at Bloomberg Intelligence, the average number of stocks traded per week in the stock market in 2025 has increased by 37% compared to the previous four years, while Friday stock trading volume has surged by 42%. Last weekend, the reasons for this leapfrog growth were fully revealed, as Trump and his Treasury Secretary released a series of trade related news, and by Monday of this week, more official announcements were made, causing a huge change in market conditions. The S&P 500 index surged 3.3%, the Nasdaq 100 index returned to a bull market, and the credit market showed a sharp decline in investors' concerns about defaults. Mark Clegg, a senior fixed income trader at Allspring Global Investments in Milwaukee, said that Benson's move is just the latest lesson on the importance of reducing portfolio risk before the weekend. He said, 'No one wants to enter the market on Monday morning after a huge change and try to correct their mistakes.' He used Friday to 'get rid of any unnecessary risks.'. However, the increase in trading speed and volume has not reduced trading costs, especially for asset management companies. In recent weeks, as the weekend approaches, their trades have been very rushed. David Schiffman, a portfolio manager at Cantor Fitzgerald Asset Management, said, "Portfolio managers are forced to sell what they can sell, not what they want to sell. Almost every day, there is a lack of direction and certainty, which is close to the most extreme level I have ever seen in my career
