Very cool! The weight rankings over time and performance views you have are awesome. I actually just started git-scraping [1] Ark's EOD holdings a few weeks ago [2] (although I'm not scraping trades out of emails since I couldn't find a trivial way to integrate them into my scraper) I wanted to be able to justify to a friend that despite 10% of their entire portfolio oftentimes being TSLA they ARE selling shares as i…

They are profit taking, for sure.

More accurately they are selling because they cannot hold (by mandate) too much weight into a single asset. So if they really like an asset they will take their maximum position and sell as it goes up even though they would like to hold on to it.

These ARK funds have been making some killer investments. I'm so excited about the companies in ARKG and PRNT.

Do you think Tesla will roll out an autonomous taxi service in the next few years? It seems that ARK believes this to be the case. I'm wondering how much their conviction on Tesla is based on this leap in tech.

Earlier quoted context omitted.

ARKK (and maybe their other ETFs) are capped at 10% per individual holding. They take profits when the holding becomes overweight. Cathie Wood has said she would hold more TSLA if she could. I don't know when or how they plan to exit if things start to go sideways.

Hold more if she could? Not according to this interview. If we had not taken profits in its ride up from [$]178 to 900 or nearly 1,000, it would’ve been ... maybe over 20% of the fund,” she said. “That would not be wise portfolio management. We like to control our position sizes.” https://www.cnbc.com/2020/05/22/ark-invest-ceo-why-weve-sold...

You know, I thought I heard her say that in an interview, but I can't seem to find it. I might be wrong on this one.

Thank you for this! I’m curious if there are products (or interest in products) where people can mirror portfolio of these etf/famous investors at a much smaller expense ratio. This can be done with a combination of data aggregation + alpaca api.

M1 Finance at least lets you set up a portfolio by weight, instead of individual trades: https://www.m1finance.com/

I believe they have an API, so you could automate it.

I'm surprised to see Roku as such a big holding for them. I wonder what their thesis. Apparently I'm not the only one confused by this https://www.reddit.com/r/investing/comments/f3my4w/why_would... https://investorplace.com/2020/08/roku-stock-is-poised-for-l...

It's not like they bought it big. It grew up. Same as TSLA.

But they've kept it as a big portion of their holdings, which means they believe it still has more to go.

Ark dropped all their shares in Illumina because they didn't see that company as continuing it's growth rate.

Do you feel like Ark will be able to perform as well as they had in the past in the upcoming years? Like how does Ark do it? How are they able to perform way better than other investors? Isn't there a mental model that sooner or later they wouldn't be able to have returns higher than market returns Disclaimer: I do hold ARK shares and options

> Isn't there a mental model that sooner or later they wouldn't be able to have returns higher than market returns Reversion to the mean. Also survivorship bias: at any given point there is a hotshot fund that outperforms the market, but fast forward five years and it's probably a different fund that did well, and the hotshot fund is underperforming the market, but nobody talks about them anymore. All that matters is…

Huh, totally forgot about Jim Simons. Thanks for some of the insights, thats a good point

Also thanks for the reminder, funny how following the latest trends and putting my focus onto those kinda made me forgot about all the other hot shots from the past that faded from the spotlight

As someone who is kicking himself every day for turning down a job with Roku a while back... I think the impression is that Roku has built a durable brand and will continue to capitalize on it going forward. Roku has not generated much profit yet, but AFAICT their expenditures are low and they can scale quite well. They are part device mfg and part advertising company, and we all know the market loves ad companies(Fa…

> As someone who is kicking himself every day for turning down a job with Roku a while back...

Same here.

I am not too bothered. Reflecting on the decision, I think the prestige of working at Google is the main reason I turned down Roku. And precisely because that Roku is a promising company, because they are focused on building a business, not building a prestige, for example, a fancy office.

That's one good lesson to learn from this event. Good enough for me.
