What this transaction means for investors
I don’t think investors should necessarily panic over William Blair’s Q4 sale of MercadoLibre. The firm pared down 10 of its top 12 holdings, and MercadoLibre still remains the 12th-biggest holding in the portfolio. Furthermore, William Blair has sold the stock in eight of the last nine quarters, so this gradual selling is nothing new. While I don’t know the exact rationale for these sales, I’d only look to buy shares of the promising e-commerce and fintech juggernaut -- especially following its 20% dip over the last year.
Since its IPO in 2007, MercadoLibre has generated annual total returns of 26%, yet its growth story appears far from over. In its last earnings report, the company grew unique active buyers, fintech monthly active users, and overall revenue by 26%, 29%, and 49%, respectively. More specifically, the fintech unit grew revenue by 65%, while MercadoLibre’s credit portfolio grew by 83%, showing an incredible appetite for the company’s banking and lending solutions in countries where these often aren’t easily attainable.
Trading at just 35 times earnings, despite growing sales by 45% annually over the last decade, MercadoLibre remains a top-tier growth stock to buy right now following its recent dip. While the company remains a reasonably large position in William Blair’s portfolio, I’m more interested in adding shares of MercadoLibre and holding them for decades than ever considering selling them too early.
