Show HN: I built a comprehensive Ark ETF tracker
- an_opabinia 6y agoIt reads like a list of trends from 2017.
- BrunoJo 6y agoLooking at the 13F filings is also a great way to track what Ark and other investors (like Buffett) are investing in: https://cheaperthanguru.com/portfolio/cathie-wood https://cheaperthanguru.com/portfolio/cathie-wood
- anonu 6y agoNot really. 13F filings are quarterly with a 45 day delay. ETF holdings are published daily with no delay on the Issuers website.
- TooCreative 6y agoDo you update the share prices every day? How do you get the data?
- isthispermanent 6y agoThe data is updated every day. They are actively managed so they'll send trade data via email if you request it.
- sakopov 6y agoARK publishes their "balance sheets" daily. I noticed that they update them usually around 6:30PM central. So you're basically just comparing with previous day's data to find deltas.
- tigger0jk 6y agoThey update their holdings every day at https://ark-funds.com/investor-resources https://ark-funds.com/investor-resources - I've been scraping that to https://github.com/tigger0jk/ark-invest-scraper https://github.com/tigger0jk/ark-invest-scraper for almost a month now (I did not make this website). They also will email you daily trade notifications if you request them: https://ark-funds.com/subscribe https://ark-funds.com/subscribe (I'm not scraping those)
- rayuela 6y agoThese ARK funds have been making some killer investments. I'm so excited about the companies in ARKG and PRNT.
- isthispermanent 6y agoIt's going to be an interesting decade. ARKG is probably the least understood of them all.
- leoplct 6y agoDo you mean underestimated or overestimated?
- isthispermanent 6y agoOf the 5 ETFs ARKG is the most underestimated. Particularly, maybe entirely, by those outside of the industry and Ark community. Grasping the impact of how genomic medicine will reshape lives is too much for your average person. That's largely the point of the ETF though, right? Total speculation on my part... but I would predict that the average life span is pushed to 100+ by 2050. Largely on the back of genomics.
- isthispermanent 6y agoInstead of editing... Differentiating life span and health span is worthwhile here. It might not be great to live to 100. But if your quality years (health span) are increased it will be. That is the primary promise of genomics, secondary is life span.
- ketamine__ 6y agoDo 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. https://ark-invest.com/articles/analyst-research/teslas-autonomous-opportunity/ https://ark-invest.com/articles/analyst-research/teslas-auto...
- sanke93 6y agoThanks for building this!
- isthispermanent 6y agoSure thing!
- sakopov 6y agoThere is also a site with similar functionality. [1] [1] arktrack.com
- rwgd 6y agohttps://www.arktrack.com https://www.arktrack.com
- korse 6y agoWhat is with the disclaimer? Not affiliated with Cathie Wood or Ark investments. This + the site name and branding is confusing at first glance.
- isthispermanent 6y agoJust want to be clear that the site has no affiliation with Ark Invest. It is a third-party.
- randoramax 6y agoThe choice of words for website is unfortunate, makes it look scammy.
- verdverm 6y agoARK Invest for those not familiar: https://ark-invest.com/ https://ark-invest.com/
- maxencecornet 6y agoReally well made!
- isthispermanent 6y agoThank you!
- jerednel 6y agothis is great. Before, i was just getting the ARKK emails and trying to "feel" what they are accumulating and selling.
- isthispermanent 6y agoGlad you're finding it useful!
- nwsm 6y agoNever heard of Ark. I checked out their site but can anyone give me some context on why they're notable?
- Stanleyc23 6y agoJust a stock noob, but they are an investment company which markets things like ETFs for buying baskets of stocks. They are known for being big proponents of Tesla stock before it blew up. Now they seem to be considered thought leaders on what is the next tech stock to achieve Tesla-like returns.
- ketamine__ 6y agoTesla is 9% of their portfolio. Tesla has a P/E of over 1000. It seems incredibly risky to hold Tesla now.
- LanceJones 6y agoIt's their strongest conviction holding. They're limited to 10% exposure to any 1 company...
- webinvest 6y agoTesla is expected to 4x it’s revenue in 2 years. So in 2 years that could be a much lower PE. Maybe try a PEG ratio or discounted future cash flows
- jrussino 6y agoFYI: On the holdings plots I see "invalid date" on all of the x-axis labels https://cathiesark.com/arkk-holdings-of-tsla https://cathiesark.com/arkk-holdings-of-tsla
- isthispermanent 6y agoAh yes, thanks for pointing it out. I suspect you're on Safari. Just tinkered with those dates yesterday. Tech note: momentjs isn't foolproof when it comes to Safari
- radicalriddler 6y agoI am also getting it on Firefox
- isthispermanent 6y agoThanks for the heads up. Fix is going out shortly
- radicalriddler 6y agoAppears to be fixed now. Good job and thank you.
- pedalpete 6y agoI'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_anyone_be_bullish_on_roku/ https://www.reddit.com/r/investing/comments/f3my4w/why_would... https://investorplace.com/2020/08/roku-stock-is-poised-for-long-term-gains-as-streaming-crushes-old-tv/ https://investorplace.com/2020/08/roku-stock-is-poised-for-l...
- hrez 6y agoIt's not like they bought it big. It grew up. Same as TSLA.
- pedalpete 6y agoBut 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.
- webinvest 6y agoYeah Roku confuses me more than any of the other holdings but apparently it has also outperformed the S&P500 so it turned out to be a good pick.
- AznHisoka 6y agoThe basic thesis is: As more people quit cable, advertising dollars move from cable TV to ad supported content on Roku.
- 01100011 6y agoAs 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(Facebook, Google, etc). As a cynical embedded guy who has worked in settop boxes for the last 20 years, I see them as having easily replaceable tech and facing stiff competition from Amazon, Google and Apple(along with unforeseen foreign competitors) in the future. I specifically avoided them because I thought they were a flash in the pan(well, it was also a brogrammer shop and I wanted to avoid that). I think they've proven themselves to have some staying power, but I think their current valuation, like a lot of the market, is just flat out silly.
- BOOSTERHIDROGEN 6y agothank you, what your view for ARK as first investment ?
- webinvest 6y agoWhat difference does it make being your first, second, hundredth, or thousandth investment? It depends on what your goals are and how you rank those goals. You’ll probably make more money with ARK funds but you won’t learn as much about picking stocks. Instead you’ll learn about picking ETFs. You’re pretty likely to wake in 10 years in a world you’re happy to live in with ARK funds. Even though that’s not the primary objective like performance is, it can help you sleep better at night. If you’re afraid of a stock market correction happening soon, SHV is likely a better short term holding for you. It’s hard for any meaningful correction to last though with QE firing up the M1 and M2 supplies. Best to only start with money you’re willing to lose so that you have the mental fortitude to ride out the INTENSE volatility you will be experiencing in Ark’s funds.
- BOOSTERHIDROGEN 6y agobetter return than S&P500, but right now its seems so overvalued.
- webinvest 6y agoTell me how you performed your valuation on the ETF
- isthispermanent 6y agoTough to give first time investment advice. You should invest for sure, but what to invest in is largely a matter of risk tolerance and expectations. Ark is much riskier than SPY (S&P 500 Index). My advice would be to invest in SPY and see how you feel after a few months. If you're not losing sleep and are comfortable with the ups and down maybe move into a more niche basket of positions, Ark being one of them.
- tigger0jk 6y agoVery 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 it goes up so it's not their ONLY holding :D [1] Git Scraping Article that inspired me https://simonwillison.net/2020/Oct/9/git-scraping/ https://simonwillison.net/2020/Oct/9/git-scraping/ [2] My ark holdings scraper (and the data) https://github.com/tigger0jk/ark-invest-scraper https://github.com/tigger0jk/ark-invest-scraper
- isthispermanent 6y agoThey are profit taking, for sure.
- bionsystem 6y agoMore 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.
- unwoundmouse 6y agoDamn I didn't realize that ant design could look so clean
- avrionov 6y agoThe website looks good, but you should change the name. It gives the wrong impression that it is associated with them.
- kevindeasis 6y agoDo 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
- webinvest 6y agoI don’t know. Early Jan could be sketchy as people sell their best performers to defer taxes on their high gainers. I would be surprised if ARK didn’t outperform the market average over any 3 year period. But I also worry about Cathie and her team’s continuing motivation after Resolute and Kelso & Company took control of Ark Invest. I wouldn’t be surprised if Cathie and her team issued a new set of replacement ticker symbols under a new name. Disclaimer: I do hold ARK shares and some bullish options positions.
- mrgordon 6y agoI agree I think she will start a new company to regain control of her own work.
- findjashua 6y agotheir conviction on bitcoin, tesla, etc has been a significant driver of their returns. if they can continue being so prescient about controversial investments remains to be seen. not taking any credit away from them - their performance nothing short of phenomenal. one thing they definitely get right is risk control/management - they cap individual holdings to 10%, so it provides profit-taking and cuts down single-holding risk by design
- sooheon 6y ago> 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 that there is a new golden child to fill financial news bandwith and get people shuffling their money around so the croupier gets paid. Of course there are outliers like Rentech, but Cathie Wood is not Jim Simons.
- programmerslave 6y agoThe real question. Remove tsla from arkk, how well did they perform?
- webinvest 6y agoLikely still better than the S&P500 and the Nasdaq 100. Hopefully someone else commenting will answer.
- isthispermanent 6y agoI can't tell you all time, but in the a last 60 trading sessions ARKK has gained 21%. This is the breakdown... https://cathiesark.com/arkk/performance https://cathiesark.com/arkk/performance
- elt193 6y agoThank 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.
- isthispermanent 6y agoI think there is a site in the UK called eToro where you can do this. I'm not sure if that's what they do, but it's something along those lines. Either way, it's a good idea. You might run into regulatory issues but I'm sure it would find a market
- stigz 6y agoYes, I'm interested. I was thinking along the same lines.
- atombender 6y agoM1 Finance at least lets you set up a portfolio by weight, instead of individual trades: https://www.m1finance.com/ https://www.m1finance.com/ I believe they have an API, so you could automate it.
- anonu 6y agoCool site and visuals. Do the trades reflect re-weights? Or do they reflect money flows (creations and redemptions) into the fund? Also for the performance heatmap it would be cool to normalize performance to the return of the S&P or of the ETF itself over that same time frame.
- isthispermanent 6y agoThe trades... great question. They reflect re-weights, so could be profit taking, a change in conviction, etc. They do not reflect creations and redemptions. The purple line on each positions holding page (https://cathiesark.com/arkk-holdings-of-roku https://cathiesark.com/arkk-holdings-of-roku) does reflect creations and redemptions. So that line can actually be seen as a combination for fund demand re-weights. Second the heat map idea. I'll put it on the list, that would be interesting.
