Foolish take
Cathie Wood and her managers at ARK Investment Management are frequent traders refining their portfolios. A portfolio adjustment based on prior share price performance is one reason the firm would sell stock. Another may be a higher conviction in another name.
The former appears to be the case here. CRISPR stock jumped 33% in Q3, closing at a price of almost $65 per share. The stock sale looks prescient now. CRISPR shares have plunged 15% since Sept. 30.
Even after the sale of nearly 400,000 shares, ARK Investment's stake in CRISPR actually increased by $139 million by the end of Q3. Investors shouldn't read more into it than ARK's managers shrewdly trading stocks.
That type of investing approach isn't for everyone. A team of researchers at ARK would likely get a better result than retail investors like us, who couldn't put that amount of time and effort into it.
