Investment Highlights Why It Matters Which of these 2 stories sounds closer for this stock?

1. Generates cash flow

The stock generated 4% or more of the share price (called cash flow yield), and shows moderate 10-15% or more growth.

2. Riding a trend

Think Tesla during the pandemic of 2020 when EVs were riding a cultural high, or Nvidia in the current AI boom, or even Figma. These companies don’t have enough yield, or, enough growth, or both - however - they are riding a trend. They have momentum. These can be more volatile - they don’t have the floor of strong cash flow
