The Globe and Mail reports in its Saturday 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. In the early hours of May 6, someone bet nearly $1-billion (U.S.) on crude oil shorts, which pay off if the price of oil drops. An hour later, Axios reported that a deal to end the war in Iran was in the works. Oil prices quickly dove by 12 per cent, and those shorts netted a cool $125-million (U.S.). It's almost like someone knows exactly what Mr. Trump is going to say, and when.
