Amphenol Corp. (US0320951017) stock closed at $157.01 on August 21, 2026, on the NYSE, marking a 2.55% gain for that session and extending a strong run in 2026.
Per the latest market data page for Amphenol, the shares also traded in an overnight session at $156.51, showing a modest dip of 0.32% after the regular close on August 21, 2026, as investor interest carried into extended hours. The detailed quote overview additionally highlights a recently announced 100% stock dividend with an ex-date of September 3, 2026, providing a clear upcoming corporate action that may reshape the share count and per-share metrics. For investors, the combination of a strong recent price performance and a pending stock dividend sets the stage for close monitoring of valuation and liquidity in early September 2026.
Fresh price levels and performance context
Recent quote data for Amphenol shows the stock trading at $157.01 as of the August 21, 2026, regular-session close, with a day gain of $3.90 that translated into a 2.55% advance for that session. The same quote source lists an overnight price of $156.51, a decline of $0.50 or 0.32%, as of 10:06 p.m. ET on August 21, 2026, indicating a slight easing from the official close but no sharp reversal of the prior-day gain.
Complementary performance figures compiled in an analyst-forecast overview place Amphenol at a recent price level of $157.04 in USD, with a one-day change of 2.57% and a five-day move of negative 5.97% as of the close on August 21, 2026. The consensus and revisions page also indicates that Amphenol has gained 16.23% since the start of 2026, underscoring a robust year-to-date trajectory that contrasts with short-term consolidation over the latest trading week.
From a valuation-momentum perspective, these numbers show a stock that has climbed significantly over the past year while experiencing normal fluctuations over shorter intervals. A year-to-date gain of 16.6% and a one-year increase of 45.3% reported in a discounted cash flow analysis underscore the strength of the medium-term trend for Amphenol by August 24, 2026. The valuation-focused overview notes that, despite a recent one-week decline of 6.0%, the shares remain far above their levels of 12 months earlier, highlighting both momentum and potential mean-reversion risk.
DCF models question the current valuation
While Amphenol stock trades slightly above $157, recent discounted cash flow modeling suggests that the shares are priced well above intrinsic value metrics derived from earnings and free cash flow as of August 24, 2026. In one earnings-based DCF model, the intrinsic value for Amphenol is calculated at $99.59, implying that the current price exceeds this estimate by a wide margin.
The same analysis provides a second lens based on free cash flow, arriving at an intrinsic value of $84.59 for Amphenol. With the stock trading at $157.01 at the time of the review, this free cash flow-based value implies that the market price is $72.42 higher than the modeled intrinsic value, pointing to significant overvaluation on this metric. The detailed DCF discussion emphasizes that both the earnings-based and free cash flow-based approaches point in the same direction: a substantial gap between the trading price and calculated intrinsic value.
The analysis also references a proprietary GF Value framework, which places Amphenol’s value at $154.87, a figure somewhat closer to the current market price but still slightly below it. That GF Value assessment indicates that even on this third metric, the shares are trading above the valuation line, reinforcing the theme that the stock has become expensive relative to three separate modeling approaches. The convergence of these models around lower values than the market price offers a quantified comparison for investors: with earnings-based intrinsic value at $99.59, free cash flow-based value at $84.59, and GF Value at $154.87, the current $157 area implies deviations ranging from a roughly $2.13 premium against GF Value to more than $72 above the free cash flow-based estimate.
From a broader perspective, the DCF-based commentary describes a margin of safety of negative 57.7% for the earnings-based intrinsic value and negative 85.6% for the free cash flow-based intrinsic value relative to the current stock price. This means that, rather than offering a buffer below intrinsic value, the market is pricing Amphenol well above the modeled fair value threshold. Such figures highlight the importance of investors scrutinizing how much future growth and margin resilience are already embedded in the valuation, given that the stock has appreciated 45.3% over the past year while these models point to more conservative intrinsic values.
Stock dividend and share structure implications
In addition to the valuation debate, Amphenol has announced a 100% stock dividend, with an ex-date set for September 3, 2026, according to the latest quote and dividend overview. The dividend summary clarifies that this corporate action will effectively double the share count by issuing one additional share for each share held, without changing the overall market capitalization at the moment of issuance.
A stock dividend of this magnitude typically results in an adjustment of the stock price once the shares start trading ex-dividend, with the per-share price falling to reflect the increased share count while the total equity value remains unchanged. For Amphenol investors, this means that post-September 3, 2026, the nominal price per share is likely to move to a lower level that corresponds to the doubled share base, even though the underlying economic ownership stake does not change. In practice, per-share metrics such as earnings per share, free cash flow per share, and dividend per share will need to be recalibrated to reflect the new number of shares outstanding.
Because the DCF and GF Value models referenced in the valuation analysis rely on per-share inputs and growth assumptions, the upcoming stock dividend adds an extra layer of complexity to near-term modeling. Investors following these frameworks should pay close attention to any updates that incorporate the post-dividend share count, as the nominal per-share values and price levels will shift once the stock goes ex-dividend. However, the core question raised by the existing analysis remains: even adjusted for the stock dividend mechanics, are the underlying cash flows and earnings trajectories sufficient to justify the current valuation premiums implied by the models?
Analyst expectations and performance backdrop
Consensus and revisions data compiled for Amphenol provide additional context for how the market has digested the company’s recent performance. The same performance table that shows the $157.04 recent price level and the 2.57% daily gain also lists the five-day performance at negative 5.97%, indicating that, despite the strong year-to-date gain of 16.23%, the stock has given back some ground in the latest trading week.
Such short-term pullbacks can reflect profit-taking after a strong run or shifting sentiment in the broader market for electronics and industrial components. While the day-filtered search results do not include detailed quarterly revenue or earnings figures for Amphenol within the latest reporting window, the valuation and performance data show that the shares are trading on a combination of strong historical appreciation and elevated expectations. With a 45.3% gain over the past year, the stock has significantly outpaced many broad-market indices, which makes the DCF models’ lower intrinsic values particularly noteworthy.
The consensus-focused page also suggests that market participants have been reevaluating forecasts for both revenue and earnings, though the exact numbers are not visible in the compact snippet. Even without precise forecast figures, the combination of performance metrics and valuation models provides a structural view: current pricing assumes continued growth and margin strength, and any deviation from these expectations in upcoming earnings releases could widen or narrow the gap between market price and modeled intrinsic value.

Closing market view on Amphenol stock
As of the latest completed regular session on August 21, 2026, Amphenol stock traded at $157.01 on the NYSE in USD, with an overnight indication at $156.51 later that evening. These levels sit modestly above the GF Value of $154.87 yet far above the earnings-based intrinsic value of $99.59 and the free cash flow-based intrinsic value of $84.59, underscoring a valuation profile where the market price carries a significant premium over several model-based estimates.
For retail investors, the key figures to monitor in the near term include the September 3, 2026, ex-date for the 100% stock dividend, the evolution of year-to-date and one-year performance after that structural change, and any upcoming earnings releases that could either support or challenge the elevated valuation implied by the DCF and GF Value assessments. With the shares up 16.6% year-to-date and 45.3% over the past year, yet trading well above several intrinsic value estimates, Amphenol’s stock currently sits at the intersection of strong historical performance and an active debate over fair value.
