How Parkev Tatevosian, CFA’s view on $AMZN changed

I've been talking all year about wanting to increase my stake in Amazon shares, and I've been able to do so at an attractive price . I have doubled my stake in Amazon stock. It now constitutes about 6% of my total investment portfolio, which is what I was aiming for.

Remember when I gave you my last wallet update, Amazon was making up about 3% of it, and I said then that I wanted it to get closer to 6 to 8%. Since I doubled my stake, it now represents about 6% of my portfolio.

The next stock I'm going to highlight as one you can buy and keep almost forever is Amazon. Amazon's strongest competitive advantage , which will be very difficult to replicate , is its fulfillment networks and logistics for its e-commerce business.

The company has spent hundreds of billions of dollars developing this network, learning how effective it is, finding ways to reduce customer service costs , and learning data from how customers buy, how they order , when they order, and so on.
