Cathie Wood, chief of Ark Investment Management, often buys tech stocks during earnings seasons.

That’s what she has done this week. Wood uses earnings seasons as an opportunity to adjust her positions.

Investors and analysts are divided on Wood. Her supporters argue she has a visionary grasp of tech investing, while critics see her as just a mediocre money manager.

Wood, affectionately known as “Mama Cathie” among her fans, gained widespread attention with an impressive 153% return in 2020 and her clear, accessible explanations of her strategy across media outlets.

However, her longer-term performance tells a different story.

Ark's leading fund, the Ark Innovation ETF  (ARKK) , managing $5.8 billion in assets, has posted a -7.91% return year-to-date, a -26% return over three years, and a 2.3% gain over five years.

This contrasts sharply with the S&P 500, which is up 23% in 2024, 9.8% over three years, and 15.6% over five years.

Cathie Wood’s investment strategy

Cathie Wood centers her investment approach on disruptive innovation, targeting high-growth tech sectors like artificial intelligence, genomics, and blockchain. Her strategy focuses on long-term potential and emerging technologies despite short-term market volatility.

Wood believes companies in these areas will potentially deliver substantial returns. However, high-growth stocks are known for their volatility, leading to frequent fluctuations in the value of Ark’s funds.

Morningstar, a prominent evaluator of mutual fund and ETF performance, has been critical of Wood and the Ark Innovation ETF.

Morningstar analyst Robby Greengold commented in a report that investing in early-stage companies with limited earnings "requires forecasting skill, which ARK Investment Management lacks." He noted that Ark’s results have swung from "tremendous to horrendous."

In a July 2024 blog post on Ark’s website, Wood defended her approach, saying that “the macro environment and some stock picks have challenged our recent performance.”

Still, she affirmed her “commitment to investing in disruptive innovation,” adding that many Ark holdings are now in “rare, deep value territory.”

Some investors remain skeptical. Over the past 12 months, Ark Innovation ETF has experienced a net outflow of $2.41 billion, per ETF research firm VettaFi.
