I consider AT&T to be a perfect company for any cash flow-oriented investor who wants to take advantage of the recent volatility to invest. The company already represents almost 3 percent of my broadly diversified retirement portfolio. In principle, I don't want individual companies to be above this three percent threshold, but I could make an exception for AT&T. The dividend is comparatively high and secured by a low payout rate and an extreme cash flow. I am also surprised and impressed by how defensively the share price has held up in the wake of the corona shock on the markets. Accordingly, the company remains a clear buy for me, especially in uncertain times.
