A new financial chapter (Ad)

Porter Stansberry says what happened last week could become the defining legacy of his financial publishing career. In a special event watched by thousands, he unveiled what he calls “the boldest undertaking” he’s ever attempted — a real-money initiative that will document every trade, decision, win, and loss in pursuit of a million-dollar mission. And the results are already surprising. One early beta tester tripled her investment income in just three trades.

If you missed the event, he’s republishing the message he sent to attendees right after it ended.
