Seriously? People aren’t investing in companies like Tesla, Square, Twilio, Paypal? That’s being unreasonably conservative.

Tesla at nearly 10% is unreasonable for an ETF. I hope it’s so overweight because of appreciation rather than active buying.

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.

Looking 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

Not really. 13F filings are quarterly with a 45 day delay. ETF holdings are published daily with no delay on the Issuers website.

Eh, my buddy runs a hedge fund that uses aggregate 13F info to generate alpha. Individually 13F filings may not be accurate, but taken together they can be very valuable.

Never heard of Ark. I checked out their site but can anyone give me some context on why they're notable?

Just 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.

If there's any trade its a "mean reverting" one - would be my educated guess.

Cool 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.

The 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) 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.

Ah 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

I am also getting it on Firefox

Thanks for the heads up. Fix is going out shortly

thank you, what your view for ARK as first investment ?

Tough 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.
