My guest today is Phil Andrews, the creator of Cathie’s Ark (cathiesark.com). I use Cathie’s Ark almost daily to source investing ideas by looking at trade data from the ARK Invest ETFs. Phil has done an amazing job making this data understandable and actionable.

Phil gives the backstory behind Cathie's Ark and the underlying sources of data for the website. He explains the many reasons for changing fund compositions in ARKK, ARKW, ARKG, ARKF, including forced buying and selling of equities due to buys and sells of the ETF shares, potential limits around how much of public companies Cathie Wood and team are willing to own and risk limits ARK observes. Phil overviews the hidden risk in how buying or selling of ARK ETF shares can compound up moves or drawdowns.

I ask Phil about recent trends in the ARK ETFs and he reviews increases in TDOC across the funds (250%+ increase in ARKK in 2 months), selling out of ILMN after a questionable acquisition and more. Phil dives deep on genomics and the implications of AlphaFold on Google, which is now an ARKG holding. We review the top holdings in his PA (TSLA, OPEN, Bitcoin) and how it has been influenced by ARK.

Phil walks through some of the many features on Cathie’s Ark, including how to review portfolio trends, contributions over specific time periods to ETF returns, tracing a stock’s growth or decline in ARK ETFs, the Trading Floor and more. Importantly, Phil highlights why it’s important to him that Cathie’s Ark will always be free and the benefits of knowledge and transparency being spread on the internet.

This conversation was awesome and I’m excited to dig into many of the names Phil talked about. I strongly recommend checking out https://cathiesark.com, the trading floor at http://tradingfloor.cathiesark.com and the Cathie’s Ark Twitter feed at https://twitter.com/cathiesark for more insights on the ARK Investing ETFs.
