WMB Is Down 11% in 82 Days. What History Says

The Williams Companies, Inc. (WMB) is down 11% from its all-time high as of August 21, 2026, and has been falling for approximately 82 days. The Drawdown Severity Score™ stands at 2.2, placing it in the yellow zone. In 27 comparable prior drops of this depth, WMB took an average of 466 days to recover.

WMB Transitions to the Yellow Zone

We monitor these transitions closely because they often mark a shift in investor sentiment. The transition from the green zone to the yellow zone indicates that the price decline has surpassed normal, day-to-day market noise. For WMB, the decline from its peak of $79.40 to its price of $70.49 as of August 21, 2026, represents a clear departure from its recent upward trajectory.

This 11.2% correction has developed over 82 days, showing a steady and persistent downward trend rather than a sudden, single-day panic. A yellow zone rating indicates a moderately elevated risk profile. This transition suggests that the stock is experiencing sustained selling pressure that warrants closer historical analysis.

Understanding the Drawdown Severity Score™

Our proprietary Drawdown Severity Score™ provides a standardized way to evaluate how unusual a stock's decline is relative to its historical behavior. For WMB, the current score of 2.2 indicates a moderately elevated level of risk. This score is calculated by analyzing the stock's complete history of pullbacks, which includes 205 total historical drawdown events.

Historically, WMB has behaved as a relatively stable asset, with an average maximum drawdown of only -5.5% across all recorded events. The average duration of these historical drawdowns is 70 days. Because the current decline has reached -11.2% and lasted 82 days, it has exceeded both historical averages, triggering the shift to a Drawdown Severity Score™ of 2.2.

The table below contrasts WMB's historical drawdown averages with the metrics recorded as of August 21, 2026.

Valuation Versus Its Own Record

The contrast between WMB's price decline and its valuation percentiles is one of the most critical aspects of the data. As of the valuation snapshot on 2026-08-20, the price-to-sales (P/S) ratio for WMB is 7.3. This ratio sits in the 98th percentile of its own daily P/S record since 2006-08-21, which means the stock is trading at an exceptionally high multiple of its sales compared to its historical median of 3.2.

Similarly, the EV-to-EBITDA (EV/EBITDA) ratio is 17.1 as of 2026-08-20, placing it in the 74th percentile of its own historical record since 2006-08-21. This ratio is elevated compared to its historical median of 13.4, reflecting that the market continues to price the company's operating earnings at a premium.

These valuation percentiles provide critical historical context, demonstrating that despite the 11.2% price decline, the stock's multiples remain high relative to its own twenty-year history. This divergence shows that the price drop has not yet resulted in a return to historical median valuation levels.

Historical Comparison: Past 10% Pullbacks

While a minor pullback is common, a drop of 10% or more is a less frequent event for WMB. Our data shows that WMB has dropped 10% or more only 27 times in its history. When the stock enters a drawdown of this magnitude, the recovery process has historically been a long-term event.

The average duration of these comparable 10%+ drops is 466 days. This historical duration is significantly longer than the average 70-day duration of all drawdown events combined. This suggests that once WMB breaks past the 10% threshold, the correction often requires a prolonged period of consolidation before reclaiming its previous highs.

The table below details the historical profile of WMB's drawdown events.

Sector Dynamics and Infrastructure Risk Factors

As a major energy infrastructure company, WMB operates in a capital-intensive sector where cash flows are typically secured by long-term contracts. This business model usually provides a defensive buffer, which explains why the average historical drawdown is a mild -5.5%. However, when macroeconomic shifts or sector-wide re-ratings occur, even contracted cash flows may not prevent valuation compression.

The current transition to the yellow zone highlights that WMB is experiencing pressures that exceed its typical defensive boundaries. Because pipeline operators carry substantial debt to fund capital projects, interest rate environments and capital expenditure projections heavily influence their performance. These structural factors often explain why deeper corrections, once initiated, take an average of 466 days to fully resolve.

Market Drivers and Recent Developments

Fundamental factors and recent corporate news help explain the environment surrounding WMB's price action. According to Yahoo Finance, WMB's second-quarter earnings and revenues lagged Wall Street estimates, which likely acted as a near-term catalyst for the selling pressure. This earnings miss occurred at a time when the stock was trading at a premium, a condition highlighted by Yahoo Finance reports.

Despite the short-term earnings drag, the long-term structural story for the company remains a topic of active discussion. Simply Wall St reported that AI-driven natural gas demand and ongoing expansion projects have fundamentally altered the investment narrative for WMB, supporting high valuation multiples. Meanwhile, institutional investors have shown continued interest: MarketBeat reported that Keebeck Wealth Management purchased 59,573 shares, while Danske Bank A S acquired 55,628 shares of the energy infrastructure company.

Key Thresholds and Metrics to Watch

As WMB navigates the yellow zone, several key metrics will help clarify whether the drawdown is stabilizing or worsening. First, we will monitor the Drawdown Severity Score™ to see if it moves higher toward the red zone or retreats back toward the green zone. A breach of the current -11.2% drawdown level would mark a deeper correction, potentially extending the duration closer to the historical 466-day average.

Second, the relationship between price and valuation will be critical to track in upcoming data updates. Investors can monitor whether the P/S percentile, which was in the 98th percentile as of 2026-08-20, begins to contract toward its historical median of 3.2. Similarly, watching if the EV/EBITDA ratio moves closer to its median of 13.4 will indicate whether the premium valuation is starting to unwind.
