Despite what some investors consider a bumpy track record, Ark Invest's Cathie Wood continues to draw attention for every move she makes within the stock market.
Wood's been busy this month, offloading a whopping $13.4 million of Roku (ROKU) -) on Aug. 4 and ditching $4.8 million worth of Robinhood (HOOD) -) on Aug. 1.

But Wood clearly believes another stock is worth putting more into: Pacific Biosciences of California (PACB) -). She increased Ark's holding in it twice on Aug. 7 -- the first buy was 140,457 shares, and the second 519, 348 shares, bringing total holdings in the company to 2.16%.
Naturally, that's a small percentage compared to the companies Wood likes to keep in her top ten. Tesla (TSLA) -) still towers over all her other picks, holding 10.63% of the ETF's weight.
Roku (ROKU) -), Coinbase (COIN) -), Zoom (ZM) -), and Block (SQ) -) make up the rest of the top five, at 9.36%, 7.84%, 6.98%, and 5.77% respectively.
Wood may have been influenced by an announcement from PacBio on Aug. 7, when the company announced a collaborative effort with GeneDx and the University of Washington to study long-read whole genome sequencing to increase diagnostic rates in pediatric patients with genetic conditions.
Wood has been putting more money into biotech on the whole this year, specifically those working with gene editing. She invested in Ginkgo Bioworks, CRISPR Therapeutics, Verve Therapeutics. and Intellia Therapeutics in June.
