Federal Reserve Chairman Jerome Powell said the pace of jobs growth is rising faster than many people expected, but it may take years before the economy has fully recovered.

On election night 2016, Gretchen Sisson was so sure Hillary Clinton would defeat Donald Trump that she and her husband invited 80 people to their San Francisco home for a party. They even had a giant sheet cake made that celebrated suffragists and the Equal Rights Amendment. On the side was written, "Madam President."

Stuck at home this spring, University of Nebraska student Alexander Kearns spent his empty hours buying and selling stocks online, learning as much as he could about investing.

"He sounded like a kid that was really, really excited to be studying something that he found interesting," says Bill Brewster, his cousin by marriage.

What no one knew was that Kearns had been trading options on a popular app called Robinhood, and at some point appears to have mistakenly concluded he had lost more than $730,000.
