This is interesting work. Have you actually bought any of these pies yourself? It would be interesting if you could report back to us on performance of these pies (which cover a subset of the contents of the ARK funds) compared to the actual ARK funds.
I have done my own experiment with a āIITU inspiredā pie. I matched the contents of this iShares IITU ETF. However, I omitted the two largest holdings of APPL and MSFT, as I already own plenty of those. Interestingly, my pie is underperforming IITU - which tells me that IITUās performance is mainly driven by APPL and MSFT. Only the AMD part of the pie is doing better.
Iāll keep an eye on these over time and how they track the main ARK ETFs, Iām hoping that Trading212 is able to add more of these stocks relatively quickly to get a good cross section. Thereās definitely more stocks in their Next Gen Internet fund compared to Genomics so I suspect some will take longer than others.
How are youāre pies doing? Thinking of doing this myself.
And do you update the spreadsheets on a regular basis? Then i know if I should check it haha.
Okay last question, how do you check what holdings Ark changes?
Theyāre doing well, up between 1 and 10% at the moment with ARKK, ARKF and ARKW performing best. Iām updating the spreadsheet every friday with new stocks/fractionals added by 212 and then every Monday or Tuesday with the latest data from ARK. They have a CSV on their website of all their holdings that you can download, they also send out a daily email with all their trading activity.
Forgot to mention I hacked at this over the weekend and automated it so you can see a live view of the stocks in each ark fund versus where they are tradeableā¦ not made it public yet as itās super server intensive! Looks something like thisā¦ and is generated every time you call itā¦so it captures all changes made in each portfolioā¦ Shows whether itās (F)ractional or (W)hole share trading too
It changes daily, in terms of manageability it depends how accurate you want the pie to be. My currently flow means it only updates weekly but is more than manageable for me
If you use T212 youāll have to account for the stock held by Ark that are not currently traded on T212. Just rebalance to 100 without them. So youāll never be āthatā accurate. But close. You can see even on my minimal screenshot T212 donāt have Proto or Kratosā¦ and Deere is whole shares only currentlyā¦and quite a few others too. You can plug the gap by getting an account with Stakeā¦ all stocks on that platform are fractional but you donāt have the option to create a āpieāā¦ so 50/50 the approach you take
Itās an actively managed ETF so they change weights and add new positions daily, in my experience only 1 or 2 small holding positions actually get added or removed every 1-2 weeks.
