I know that Cursor and the related IDEs touch millions of secrets per day. Issues like this are going to continue to be pretty common.

The idea of a universal AI assistant across the desktop is cool. Like the emphasis on local processing and provider choice.

I have tried out V1 and while it's a bit barebones, the planned features like 'Autocontext' and 'Local-RAG' sound promising. Devil's in the implementation details though.

Yes we've thought about them a fair bit.

We believe that in most ETFs right now the transaction costs are largely factored into either the expense ratio or the ETF bid-ask spread, exactly due to the redemption mechanism you discussed. See section titled Spread of the Underlying Securities in an ETF Basket in the following PDF and the following quote:

"If a market maker has to obtain a portion of the ETF constituents on the secondary market to then deliver into the fund as part of the basket process, the cost of acquiring those names should be reflected in the ETFs bid/ask spread — as costs are traditionally passed through to the end customer."

Also we take estimated spread costs into account when running our portfolio optimization. A higher bid-ask spread as measured by past 1 month NBBO p50 spread generally gets penalized in our portfolio optimization all else being equal, although this depends slightly on what optimization setting you've chosen on Double.

You are correct the in-kind creation/redemption pushes any taxable gains/losses to the trading of the ETF by the holder, not the ETF itself.

But there are some benefits to doing what you refer to as a "custom one-off fund". Namely we can Tax Loss Harvest any losses and realize those to offset gains we realize in the name of rebalancing. The industry generally calls this direct indexing and wealth clients with $1M and above portfolios have been doing it for years.

We also provide the option of entering a "Buy & Hold" optimization for strategies, which would not rebalance your winners into losers and realizing any gains or losses, but your portfolio will drift over time if you choose this.

Other than fees, we are also quite a bit more customizable than most other options you mentioned. We let you do things like rebalance between positions and pick your optimization type, and backtest a screened portfolio. More customizable than most robo-advisors out there and more powerful than brokerages like M1.

No relation but I have shared some emails with the founder and we are both in SF I believe.

We choose to lead with the expense ratio savings in this marketing push, but I really think the platform allows for the best investment account out there with tax loss harvesting built in, dollar cost averaging between positions and stock or sector customization.

I'd argue the specifics are quite a bit different than Yotta/Synapse.

We do not hold any funds ourselves. You connect your bank and ach/wire money to an Apex bank account. You can verify your holdings via apex anytime (see: https://help.double.finance/en/articles/10262406-how-can-i-v...)

We don't currently offer Roth IRA or 401K accounts, but once we do then yes it would be possible to transfer the account without changing the tax-advantaged status.

We optimize (look at the account) daily but only trade if the portfolio meaningfully improves.

We take into account tax rates while optimizing your account. You can also chose to put your strategy in Buy & Hold which will never sell anything thus never realize any cap gains.

If Double goes out of business, your assets are safe and held in your name at Apex Clearing. They have processes in place for these scenarios to help you access and transfer those assets.

SIPC protection covers against a brokerage firm failing, which in our case is Apex Clearing. We are not currently a brokerage so SIPC would not apply if Double goes bankrupt.

Yes we allow this right now very easily, although we don't call it "soft shorting". You can remove or de-weight specific stocks or sectors quite easily.

Fair point! We also let you build a pretty customized indexes, and migrate between positions easily over time. For example, you can diversify away from your employer or your employers sector, or over or under weight specific stocks you'd like.

Very fair! Bogle is the true OG and our inspiration

Interesting - how can we make this more believable? Link to their LinkedIns?

Thanks - worked hard on the backtester despite it not being front and center product wise.

We currently have 50+ strategies. About 30 of these replicate popular ETFs. MTUM is one of them (https://double.finance/p/explore/124). Here are our 4 factor focused portfolios (https://double.finance/p/explore/factor-thesis). If there are more you want to see please let us know as we can most likely add them.

MIDU is unfortunately not eligible to be traded on a fractional basis by Apex. Main things missing are some new/low volume ETFs and ADRs (although we have some of them).

Appreciate that and its good feedback.

Complementing a Direct Index US 500 portfolio with Small Cap or International ETFs is very possible. You can exposure yourself to US Small Cap and International through ETFs - there is the related ETF expense ratio in that case.

Appreciate the kind words and feedback.

The account is opened in your name and your securities are held in your name at Apex Clearing. Apex has more than 19M brokerage accounts opened.

We are Registered Investment Advisor (RIA) regulated by the SEC.

We can ACAT in existing positions to an Index yes, which would be "seeding" an index with shares you already own.

As for taxes, we provide a yearly summary for realized gains and losses that most tax professional can plug into their software.

And for TLH, yes for larger portfolios (above 20 tickers) we create a factor model of the portfolio using 4 factors - Momentum, Value, Quality and Min Volatility. When a stock is identified for TLH purposes, we will sell it and try and bring your overall portfolios factor exposure back in line. This provides for a much more flexible and robust way to do tax loss harvesting because not every stock has a relevant pair (for example a stock that just recently merged with another business might have no clear comparables)

Great question. The bid-ask spreads of the ETF itself already take into account the bid-ask spreads of the underlying securities, since there exists an arbitrage opportunity via the ETF redemption mechanism.

I found this PDF from State Street quite informative on the topic. We are working on our own data here as well and aim to share that down the line.

Yeah it's an interesting point. Due to the redemption mechanism of ETFs, my understanding is that an ETF's bid-ask spread is basically the weighted average of the bid ask spread of it's underlying holdings. Which to answer your questions means that buying the individual stocks within an ETF would result in approximately the same slippage as buying the ETF itself.

"Bid/ask spreads of the underlying securities directly impact the costs to market makers to trade ETFs" from this .pdf: https://www.ssga.com/library-content/pdfs/etf/au/spdr-au-etf...

You can do this quite easily with Double. If you pick the US 500, you and completely remove the Energy Sector.

We are working on getting some more ESG focused portfolios directly live but it's very very do-able right now.

This is an older version of our Form ADV - we're fixing this now. We've updated our ADV with the SEC but this link remains attached to our older one.

This is our current latest filed with the SEC:

Sorry about that - we will try and make this clearer. I am happy to delete your account for you. Please email us at support@double.finance.

You are correct in your understanding.

Apex Clearing's website is here: https://apexfintechsolutions.com/ They have 19M brokerage accounts and a lot of brands you've heard of got their start with Apex (Robinhood, Wealthfront)

We're US based and regulated a RIA by the SEC.

Appreciate the thoughtful response. I hear you on switching costs being quite high for a brokerage and its very much a considered purchase. I'd love for Double to be considered in the future.

We use fractional shares. But otherwise you are correct, our minimums are set to allow you to buy at least $5 of each member of the US 500.

We do not charge trade commissions. There are some SEC fees charged for trading across most major brokerages. The national best bid offer (NBBO) means you will get executed at the current best price for a given security across all exchanges.
