Hiya! Dan DeFrancesco in a balmy NYC. If you went a little too hard on the chocolate yesterday, I've got you covered with seven tips from a dietitian on how to go on a sugar cleanse.

On tap, we've got stories on why macro traders are the hottest thing going on Wall Street, a fintech that just got backing from Reddit cofounder Alexis Ohanian's venture arm, and why aliens don't want to hang out with us just yet.

But first, you might not know them, but you should.

1. The keeper of the keys.

Some of the most powerful people on Wall Street are men and women you've never heard of.

A CEO's chief of staff is an important but largely behind-the-scenes job that serves as the gatekeeper between the top boss and the rest of the world. 

If you're familiar with the title, it's most likely from politics, not finance. The White House chief of staff, which coincidentally just changed, is the most well-known CoS (not sure this is an actual abbreviation, but just go with it). And as The New York Times covered in 2017, Hollywood has become somewhat obsessed with portraying the role in various movies and TV shows. 

Regardless of the industry, the broad strokes of the responsibilities of the CoS remain the same: serve as a top executive's right-hand person (or left-hand person for us lefties!).

Insider's Rebecca Ungarino has a report on BlackRock CEO Larry Fink's newest CoS, Willie Alford. What's interesting about serving as Fink's CoS is that it has served as a career springboard, so to speak. As Rebecca maps out, previous CoS have gone on to serve in high-profile roles, both at BlackRock and elsewhere. 

You can get the full rundown on the history of the position here. 

Something else Rebecca pointed out to me was that, so far, Fink's CoS have either been women or people of color, which is somewhat notable considering how white and male dominated Wall Street is.
