Most people buy assets based on feelings. There's a 26-hour MIT course that proves exactly how much that costs them. Ricardo Caballero. Former head of MIT's economics department. One of the most cited macroeconomists on the planet. He doesn't teach you "investing." He teaches you the one formula that prices every asset on Earth. Present discounted value. Sounds boring? That's why most people will never learn it. Here's what Caballero shows in the first few lectures alone. Every stock, bond, and property you've ever bought is just future cash flows divided by a discount rate. Change the rate by 1%, and billions move. Not because anything real changed. Because one number in one equation shifted. And the Fed controls that number. They raise it. Your portfolio drops 30%. They cut it. You feel rich again. Same companies. Same earnings. Same economy. Different price. Now think about that. Every time you panicked and sold at the bottom, someone who understood this formula was on the other side of your trade. Buying. Calmly. Mathematically. Caballero proves it with bonds first because the math is naked. Then equities. Then he gets to bubbles, where he shows the exact moment prices disconnect from the formula and crowds start trading stories instead of numbers. I've sat through lectures from Harvard, Yale, Stanford. None of them made me feel this stupid this fast. That's how you know it's good. Save this. Watch it on 1x. You'll want to rewind.
