Incorporating also the more recent history of stock markets all over the world, he elaborates on the puzzling size of the equity premium. very high historical return of stock market investments. After introducing the notion of an Efficient Portfolio Frontier, he covers the concept of the Tangency Portfolio, which leads him to the Mutual Fund Theorem.

About the Site 🌐

Origins of the Idea 🌱

The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠

Challenges Faced 🤔

Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.

Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍

Creating Truly Random Links 🛠️

The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.
