iav — Wed, 06 Aug 2025 15:37:03 +0000

This is pretty comprehensive. I work at a quant firm, and we don't even have some of this implemented in code. The tricky part is always going to be the integration. Nautilus has its own OMS system, but so does IBKR, and there is no guarantee that they are going to match.

For very small funds, running entirely on IBKR platform (or Alpaca if you can live with their constraints) makes sense. For very large funds, you invariably will have a home-grown system that integrates with all of your expensive vendors. But if you are starting from scratch and want to scale up, using this to bootstrap quickly is most efficient.

Items that contain multiple elements get the highest tariff rate of any of them - a glass window with aluminum frame gets the aluminum rate because it’s the highest one.

New comment by iav in "Xerox to acquire Lexmark"

iav — Tue, 24 Dec 2024 01:50:03 +0000

1. To allow the merger, Congress imposed some pretty onerous restrictions on any collaboration between the two companies. There is a Lexmark board of former US generals who are supervising the divison. 2. Nine star is the owner, but a lot of the preferred equity used to fund the deal came from PAG, an asian private equity firm. Their investment accrues at a pretty high interest rate and eats into Ninestar’s returns. 3. The whole thesis was that Ninestar would be able to control the amount of counterfeit ink for Lexmark printers. But with another Trump term, and lack of ability to integrate the two, the thesis is broken.

you need a lot more than 2 bidders for the theory to hold. Repeating the auction just seems pointless, but another avenue could be for the assets to not be sold, and the claimants to receive 100% of the equity of the business. Then over time they can potentially see a better recovery than what they are getting from a sale.

I am an investor in equifax. Let me clear up a misconception on where the data comes from. Half the data comes from large enterprise customers, who “sell” the data in exchange for Equifax doing I-9 verification for free. The other half comes from 39 payroll companies. Every single payroll company except for Rippling and Gusto sell paystub data to Euifax. (Rippling will start next year). Those are exclusive revenue share deals. You cannot be a competitive payroll provider without the revenue share from Equifax. So before you blame your employer, they might not be selling it directly and even if they opted out, your payroll company will sell it anyway.

New comment by iav in "High Interest Savings Leaderboard"

iav — Fri, 23 Feb 2024 14:04:08 +0000

Not to overcomplicate things, but anyone planning to save money for >12 months should be using the BOXX ETF (https://etfsite.alphaarchitect.com/boxx/) to convert the interest income into a long-term capital gain. Even if you end up cashing out before the 12 months, you are still going to pay the same taxes as with a savings account, so there is truly no downside.

If a developer is replacing a 2 story, 20 unit building with 20 parking spots with a new 5 story, 50 unit building, they shouldn’t be able to have more than 25 parking spots, as that is already a net increase from the status quo and will thereby increase traffic and congestion (the street isn’t getting wider…). The logical fallacy here is that it assumes those 25 units without a spot won’t just street park.

Apple Health does a great job of integrating with EMR providers. I can see notes from every doctors visits, my blood test results, Covid tests, and so on all integrated into one app. I can see my sodium levels have gone down since 2019 in a plot chart, or when was the last time I got sick.

Hmm, I would like to see a citation on that second comment. You can look at Frontier's last earnings release, they spent $168M of build Capex to pass 332k homes, or $506/home passed in the last quarter. Note that "passing" a home is not the same as connecting a home, there is additional cost involved there. And Frontier has tremendous cost benefit from the fact that they already own the telephone poles that they can reuse and have been doing this for decades at massive scale.

If you think the entire cost of laying fiber is just the cost of boring/digging, then you don't know what you are talking about.

iav — Mon, 13 Nov 2023 20:40:31 +0000

The locks are filled with recycled water that is stored in water saving ponds [1], but this only reuses 60% of the water and it doesn't address the other issue that if the water level in the natural lakes in Panama interior is too low, then ships will have a harder time navigating between the locks.

WinRAR is (was?) developed in Russia, so it always seemed like a great way for the Russian FSB to hack foreign systems.

Short of flooding our cities and towns in the valley, how does one replenish groundwater? My understanding is that's sort of like putting toothpaste back into the tube.

when the gain shows up is irrelevant - IRS requires taxes to be paid on income in the quarter it is realized. Everyone needs to pay the estimated tax and then file the return for the final adjustment.
