In this episode of Money Lessons, Andy explores one of the most misunderstood practices in financial markets — short selling. He traces the origins of the practice to Isaac Le Maire and the Dutch East India Company in 1609, walks through the mechanics of borrowing shares to sell them, and explains the asymmetric risk that makes short positions fundamentally different from owning a stock. 

He brings the lesson to life with the spectacular 2008 Volkswagen short squeeze, when the German automaker briefly became the most valuable listed company in the world.

In this episode of Money Lessons, Andy breaks down the three most common ways companies change their share structure. He explains how stock splits work — including Apple's five splits and Warren Buffett's famous refusal to split Berkshire Hathaway—and why reverse stock splits often signal trouble.

He then explores share buybacks, how they boost earnings per share, and why investors need to look past the headline numbers to see whether real value is being created. The episode also covers dilution and why issuing new shares comes at a cost to existing shareholders.
