The Globe and Mail reports in its Saturday, May 23, edition that suspicious trading patterns, suggesting advance knowledge, often emerge just before President Donald Trump announces major news, leading to significant profits. The Globe's Tim Shufelt writes that Mr. Trump's accounts show about 3,500 stock trades this year, many linked to his own market-moving news. It appears he is using the presidency for substantial financial gain. His first year back in office was the most profitable of his life, bestowing $3-billion (U.S.) in wealth on the family fortune. Massive trades are repeatedly executed moments before major developments that only Mr. Trump's inner circle could have known about. In March, more than $800-million (U.S.) worth of oil futures changed hands minutes before Mr. Trump announced strikes on Iran's infrastructure would be postponed. Some of those trades have their own red flags: A purchase of Nvidia shares, one week before the U.S. government cleared the company to sell some of its artificial intelligence chips to China, for example. Mr. Trump's accounts also loaded up on Palantir shares just before he promoted the company on social media.
