Porter Stansberry, founder of one of the world's largest financial research firms, says he's breaking the biggest story of his 26-year career. A famous historian whose books have sold over 45 million copies in 65 languages is warning of a structural shift so large it has only one historical parallel - 1776. One Stanford economist calls it 'the biggest change ever - bigger than electricity, bigger than the steam engine.' Stansberry outlines the stocks to buy, the stocks to sell, and three money moves to position yourself on the right side of this shift.tc pixel

Tesla. SolarCity. Twitter. This $4 stock is next. (Ad)

Elon Musk has a clear pattern: when a supplier becomes mission-critical, he acquires it. He bought SolarCity for $2.6 billion and Twitter for $44 billion. Now one small company makes the equipment his Colossus supercomputer - a million GPUs consuming nearly $1 billion a month in power - cannot run without. Analyst Dylan Jovine has identified the name and ticker. For investors who own shares before a potential move, the math could be significant.tc pixel
