Income equality is not a problem as such. It's a natural consequence of technology seeping more and more into society. In Shakespearean times all musicians made money by performing. The best ones performed for the king and made more mo

This fleece vest is something that's come across from trading floors. It started at SAC capital management (now Point 72). SAC was famous for very carefully creating an environment for peak efficiency. Noise was bad for concentration,

AI arrived in Investing a long, long time ago. If you limit AI to deep learning, as in deep neural networks, maybe only 3-5 years ago. Strategies based on news have been around for decades. Figuring out what the news means isn't necess

The price increase for Retrophin from 12.50 to 750 was NOT for no apparent reason. The previous owners of the rights sold the rights cheaply because they were unable to make money selling Retrophin, and in fact had large losses for years, d

One more thing. We are pre-launch. If we had already launched then I think startup school would have been much more helpful than it was, because the checking in every week with revenue numbers would have created a lot more urgency. A lot of

4% is probably a reasonable rate given current market interest rates for a debt you expect to be paid back. We are in the middle of an epic central bank created bubble for debt securities. Rates have never been this low. 4% is nowhere near
