The article you linked isn't great. It attacks a study that no one finds credible, which labeled a company's entire SG&A as "marketing" and found that "marketing" so measured was 10x R&D. It also preda

I'm not sure how taking the corporate rate to zero addresses any of the issues raised here. The 16th amendment only authorizes an income tax. A tax on unrealized gains would likely be a "direct" tax, which makes it a non-sta

(1) Black-Litterman is literally the only useful thing to come out of GS ever. (2) LTCM employed a Nobel winning economist too. Was that "brain trust" the source of PnL, or was it cheap leverage? Fun fact on LTCM and GS and 1998:

Because GS has never been about having a "brain trust". It is about proximity to power. That peaked in 1998 when Time magazine ran the "Committee to Save the World" cover, featuring Bob Rubin, Larry Summers, and Alan Gr

I'm not saying things aren't better now than they were in 2000. I'm just saying that systematic hedge funds make directional bets and hold positions overnight. These activities move the midpoint. That is a hidden cost not vi
