Nearly there! Dan DeFrancesco in NYC, and I can't stop looking at this awkward photo from the debt ceiling negotiations. House Speaker Kevin McCarthy looks like me when my wife promised we'd only take two photos but starts making different poses.

I'm still collecting questions for a future mailbag. Submit any questions you have via this Google Doc. (It's anonymous.) No personal finance questions, please.

Today, we have stories on why Apple poses a big threat to neobanks, the dealmakers still making money amid a drought, and summer-friendly button-downs.

But first, can I tell you a secret?

1. That's why her hair is so big. It's full of secrets. 

Coca-Cola's syrup formula. KFC's recipe for its fried chicken. Citadel Securities' trading strategies?

You've likely heard of how closely Coke and KFC guard their secrets, but the massive market-making firm might be the most protective of the bunch when it comes to its "secret sauce."

Look no further than a recently filed lawsuit by Citadel Securities against two former employees, per Bloomberg. The suit, which you can read here, alleges the former employees were building a competing high-frequency trading firm while still employed and used trade secrets gained while at Citadel Securities.

Leonard Lancia and Alex Casimo unveiled Portofino Technologies, a market-making firm focused on cryptocurrencies, in September 2022 with $50 million in funding from backers like Coatue Management. A major part of the pitch? Invest with the guys who had a front-row seat working at one of the top trading firms in the world, per the complaint. 

Portofino's announcement also came just a few months after reports of Citadel Securities working on its own crypto-focused brokerage with a slew of other high-profile firms.  Portofino told Bloomberg that the Citadel Securities lawsuit was "corporate bullying" and that it would defend itself.

Whichever side you fall on regarding the lawsuit, it does raise some interesting questions about Wall Street's trade secrets and the extent some firms will go to protect them. 

On the one hand, trading firms invest a lot of money — check out some salary ranges here — in developing these strategies. Margins are thin, and the difference between making and losing money comes down to fractions of a second, literally.

But I also don't want to live in a world where employers can limit the future earning ability of their workers on the basis of  "trade secrets."

If you think this isn't top of mind for every trading firm in the world, think again. As Insider's Alex Morrell has previously covered, preventing employees, particularly quants, from defecting to rivals is a top priority.
