How Much Could You Lose In AT&T Stock?
For questions about this article or underlying research, email help@trefis.com.
AT&T (T) stock lost 14.5% over the month to October 28, 2026, while the S&P 500 gained 1.0%. Its two largest one-day drops, 9.8% on October 9 and 8.0% on October 23, came on news that SpaceX aims to become a major U.S. mobile carrier. Many investors hold AT&T for its 5.6% dividend yield, trusting the shares to fall less than the market in a sell-off and its cash to keep paying the dividend. So when the market sells off, how far has AT&T stock actually fallen before?
How Far Has AT&T Stock Fallen In Past Sell-Offs?
AT&T stock fell as much as 45.0% in the 2008-2009 financial crisis. This marked its deepest drop across market shocks since 2007, while the S&P 500 fell 53.0% over the same dates. The performance fits a wider pattern: across the 14 shocks AT&T traded through, the stock fell 14.0% on average, against a 16.3% decline for the index.
The stock has fallen less than the market on average, but not every time. In the 2023 regional banking crisis, AT&T fell 20.0% while the S&P 500 fell 6.7%.
Recovery times varied widely. From its low, the stock regained its earlier high in a median of 3.4 months, yet four of those recoveries took more than a year. After the financial crisis, the wait was 37.7 months. The falls and recovery times above are measured on past closes that may also count dividends paid.
What Does AT&T Earn, And What Does It Owe?
AT&T earns a wider operating margin than at any time since 2016 and makes enough cash to cover its dividend, but it owes more than it did a year ago. Over the twelve months to September 30, 2026, its operating margin was 21%. That was the highest twelve-month figure at any quarter end since 2016. In the third quarter alone, revenue grew 5.3% from a year earlier.
AT&T produced $17.8 billion of free cash flow over the same twelve months, more than twice the $7.94 billion it paid in dividends. Yet its total debt rose to $178 billion at the end of September, up from $158 billion a year earlier.
AT&T Faces Falling Fiber Prices And Higher Debt
On its October 21, 2026 earnings call, management said average revenue per fiber customer fell 4% from a year earlier in the third quarter. Management tied the fall to introductory prices, discounts for customers who also buy wireless, and lower-priced plans in areas bought from Lumen. It expects a similar decline in the fourth quarter. It also expects higher marketing and customer acquisition costs to weigh on that quarter’s adjusted EBITDA growth.
AT&T’s borrowing has also risen against its earnings. Net debt was 3.13 times adjusted EBITDA, a measure of operating earnings, at the end of the third quarter. This ratio is up from 2.68 times at the end of the second. Management tied the rise to AT&T’s $23 billion purchase of spectrum licenses from EchoStar at the end of July. It expects the ratio to return to about 2.5 times during 2029 through earnings growth and debt repayment. Management plans to fund that repayment with spare cash and with proceeds in 2027 from closing a fiber joint venture and the planned sale of AT&T Mexico. AT&T is expected to report its fourth-quarter results in January 2027, and its net debt against adjusted EBITDA is the measure to watch then.
