snake_doc··on Nvidia’s $589B DeepSeek rout
No, the only thing that matters is if the portfolio delivers returns in excess of your cost of capital.

If your portfolio is green, you can still be a poor performer.

snake_doc··on Nvidia’s $589B DeepSeek rout
The other way is certainly also true. Your short piece is rational, but lacks insight into the inference and training dynamics of ML adoption unconstrained.

The rate of ML progress is spectacularly compute constrained today. Every step in today’s scaling program is setup to de-risked the next scale up, because the opportunity cost of compute is so high. If the opportunity cost of compute is not so high, you can skip the 1B to 8B scale ups and grid search data mixes and hyperparameters.

The market/concentration risk premium drove most of the volatility today. If it was truly value driven, then this should have happened 6 months ago when DeepSeek released V2 that had the vast majority of cost optimizations.

Cloud data center CapEx is backstopped by their growth outlook driven by the technology, not by GPU manufacturers. Dollars will shift just as quickly (like how Meta literally teared down a half built data center in 2023 to restart it to meet new designs).

You clearly have never lived in convenient (but high costs) parts of Manhattan.

snake_doc··on TSA Policy on Light Sabers
A common analogy is to think about traffic lights.

If you run a penetration test, asking an individual to run a red light. You will achieve near 100% success.

However, when the traffic lights change actors’ behaviors to stop (at some probability such that it results in less collisions), most actors will stop according to the traffic lights.

The effectiveness of a security program cannot solely be measured by penetration tests under controlled circumstances. Aspects of deterrence and standardization required by the program fundamentally changes the threat actors’ calculus.

This is the very fundamentals of mixed strategy calculations in game theory.

The Redfin YoY price change he quotes is a median price change.

snake_doc··on Private Equity Is Now Dominating the US Hospice System
Private equity owners often have less short term incentives because their funds are usually 10 years long.

On average, an investment from purchase to exit may take ~5 years.

Whereas a public company with large institutional owners will have to respond to market feedback in real-time, i.e they are more likely to follow the herd if institutions (pension funds) demand a shift in industry trends (ie ESG). Whereas, private equity have no such concerns.

snake_doc··on Requiring banks to issue long-term debt could make customers safer
Original headline: “How risky bank debt makes customers safer”

This HN headline is editorialized… The article mostly explains the difference in loss absorbing debt regulators for banks with $100B+ in assets.

Separately, it is a false premise to argue that the median retail banking customer is not “safe”.

The US banking system is incredibly safe for the vast majority of its customers. Those customers with uninsured deposits are not in the majority.

snake_doc··on Venture Predation
Amazon isn't unique in this case. Your example is a bit of cherry picking. These tactics are common in retail (demonstrated by the fact that WMT, AMZ, and COST are the top 3 retailers in the world).

> access to capital at cheaper rates than most countries due to their position as a stock market darling

Last I recall, AMZ uses an internal WACC of 8-9%. That's really only marginally "cheaper" cost of capital than most other mega-cap firms, it's not really a big advantage.

Its cost of capital advantage mostly comes from its access to cheap short-term credit in its retail cash cycle, not the equity market (like you suggest).

> "reinvesting in the business" to bleed competitors dry. Few other companies on the planet have the ability to run negative or break-even margins the way Amazon does.

Costco regularly runs negative or break-even margins in its merchandising. Its language for this is "reinvesting in value" or "reinvesting in price". It can do this, similar to Amazon, because of their membership business.

Walmart also regularly runs break-evens/negative margins in select merchandising lines depending on geography and competition.

snake_doc··on JPMorgan Chase Bank Assumes All the Deposits of First Republic Bank
The spoils go to…

“As a result of this transaction, JPMorgan Chase expects to:

Recognize an upfront, one-time, post-tax gain of approximately $2.6 billion, which does not reflect the approximately $2.0 billion dollars of post-tax restructuring costs anticipated over the next 18 months

[…]

The transaction is expected to be modestly EPS accretive and generate more than $500 million of incremental net income per year, not including the approximately $2.6 billion one-time post-tax gain or approximately $2.0 billion of post-tax restructuring costs expected over the course of 2023 and 2024.”

No, the BTFP is a separate line on the weekly lending release H.4.1. The lending to FDIC is entirely separate (on the line after).

Also, FDIC bridge banks are not eligible for BTFP, because they are not eligible for the primary discount window. They are banks in default…

snake_doc··on JPMorgan Chase Bank Assumes All the Deposits of First Republic Bank
Technically, the Fed has been providing most of the liquidity to the FDIC in the last 2 months. The FDIC isn’t liquid. This most definitely is “printing” money as the Fed generates money in the system when it lends.

If you look at the Fed’s weekly lending (H.4.1), you can see the FDIC has borrowed upwards of 170B in the last 2 months, not including FRC deal. In the FRC deal, FDIC is giving JPM a 50B term loan, which is most likely again borrowed from the Fed.

There’s some speculation why this had to happen, ie the Treasury cannot provide the liquidity due to debt limit, etc…

snake_doc··on Apple Pay’s long road to paying off is getting shorter
This is the one of the last ultimate service plays (the best one remains to be healthcare, which they are working on) in the shift to service transition.

If your savings are on Apple Wallet, you will be not switch away from an iPhone for many years. The average deposit duration is 7 years, used by banks to manage risk. This “lock” is better than any carrier 24-36mo agreement.

Healthcare obviously would be groundbreaking, if you depend on your phone for healthcare (it would be potentially life long…).

So regardless if they make money on these services, they’ll continue to make more money on devices.

snake_doc··on Lazard’s Levelized Cost of Energy Analysis: Version 16.0 [pdf]
For the record, it’s usually criticized dependent on the individual’s views on intermittent vs. non-intermittent… Just as green hydrogen is heavily criticized by skeptics vs advocates…

It’s not criticized broadly by the entire energy industry…

snake_doc··on Lazard’s Levelized Cost of Energy Analysis: Version 16.0 [pdf]
Yes, though those effects are much less on an incremental basis for any technology already at scale. The mechanisms still exist, but delay is longer.
snake_doc··on Lazard’s Levelized Cost of Energy Analysis: Version 16.0 [pdf]
You’re describing energy market price (LBMP) dynamics. LCOE isn’t a price, it’s an cost estimate for the lifetime of an “power plant”.

LCOE is an input to deciding whether to build a new power plant in a market. The market’s LBMP is another input. Super simplified, if the market’s average LBMP is lower than LCOE for the plant, the plant shouldn’t be built…

snake_doc··on Lazard’s Levelized Cost of Energy Analysis: Version 16.0 [pdf]
Great to see updated figures. Unfortunate to see average LCOE go up for existing renewables due to the double whammy of price level rise (inflation) and cost of capital rise (interest rate).

These 2 factors also make it more difficult to commercialize frontier renewables like green hydrogen.

snake_doc··on What does “excess liquidity sloshing around the financial system” mean?
Your example doesn’t make any sense. The entire reason for the US Fed’s interest rate is to dictate the lower nominal bound of market returns in global capital markets. The FedFunds rate is the risk free rate, thus the market rate of return cannot be lower than this rate. Ie. The public equity market will return risk free rate + market risk premium.

A better explanation would be:

A pension funds needs to achieve long term nominal returns of 5% to meet liabilities.

Fed funds rate is suddenly set to 0%, and treasury curve peaks at 2%.

Market risk premium is 5% for public equities.

Market risk premium is 10 % for private equities.

To reach target returns while anticipating volatilities, it must allocate capital towards both public and private equities. This is the “sloshing”. Simple mathematics.

Side note: any retail investor can access the risk-free rate (very close to it, minus transaction costs/expenses) through large money market funds. ie. https://investor.vanguard.com/investment-products/mutual-fun...
