Valuation Models Diverge Across Major Stocks

A series of recent Simply Wall St analyses released on 5 April 2026 highlight how different valuation models are producing contrasting signals for several large, widely followed companies across sectors, including technology infrastructure, utilities, diversified financials, insurance, luxury goods and conglomerates.

The reports cover Equinix, Southern, Global Payments, American International Group (AIG), LVMH Moët Hennessy – Louis Vuitton Société Européenne, and Berkshire Hathaway (BRK-B), comparing market prices to intrinsic values derived from Discounted Cash Flow (DCF), Excess Returns and price-to-earnings (P/E) based approaches.

Equinix shares recently closed at US$1,000.37 after a strong run, with returns of 3.9% over 7 days, 6.7% over 30 days, 30.9% year to date and 33.6% over the past year. The stock has attracted attention as a data center and digital infrastructure operator tied to cloud and connectivity themes.

A DCF model using a 2‑stage Free Cash Flow to Equity approach based on adjusted funds from operations starts from last twelve month free cash flow of about US$3.8 billion and extends forecasts to 2030, when projected free cash flow reaches US$6.2 billion. This produces an estimated intrinsic value of about US$1,420.75 per share, implying Equinix is undervalued by roughly 29.6% versus the recent price.

On a P/E basis, however, Equinix trades on 72.81x earnings, well above the Specialized REITs industry average of 15.86x and a peer group average of 37.46x. Simply Wall St’s Fair Ratio for the company is 33.19x, and the gap between this Fair Ratio and the current multiple suggests the shares screen as overvalued on this metric. Overall, Equinix scores 2 out of 6 on the platform’s valuation checks.

Southern Company’s stock last closed at US$97.45, after posting returns of 2.0% over 7 days, 11.8% year to date, 13.2% over 1 year, 49.9% over 3 years and 87.2% over 5 years. The utility has been in focus for how it manages long term infrastructure needs and regulatory expectations in the US utilities sector.

A DCF analysis using a 2‑stage Free Cash Flow to Equity model projects free cash flow to equity from a loss of about US$1.49 billion over the last twelve months to US$593 million in 2026 and approximately US$12.54 billion in 2035. Discounting these cash flows and adding a terminal value yields an intrinsic value estimate of roughly US$202.05 per share, indicating Southern is about 52–53% undervalued relative to its recent price on this model.

Southern trades on a P/E of 25.13x, above the Electric Utilities industry average of 21.87x but below a peer group average of 28.03x. Simply Wall St’s Fair Ratio for Southern is 26.44x, slightly above the current multiple, and this comparison leads the analysis to view the shares as modestly undervalued on the P/E measure as well.

For Global Payments, which has experienced extended share price declines, the stock recently traded at US$64.05. It is down 2.8% over 7 days, 16.2% over 30 days, 15.2% year to date, 23.6% over 1 year, 37.2% over 3 years and 68.6% over 5 years, amid broader reassessment of payment and fintech names.

An Excess Returns model that uses a Book Value of US$96.70 per share and a Stable EPS estimate of US$17.31 per share, based on future Return on Equity estimates, calculates an Average Return on Equity of 16.86% and a Cost of Equity of US$9.71 per share. This produces an Excess Return of US$7.60 per share and an intrinsic value estimate of about US$228 per share, which implies the stock is 71.9% undervalued compared with the current price.

Global Payments’ P/E of 16.43x is close to the Diversified Financial industry average of 15.79x and well below a peer group average of 30.90x. Simply Wall St’s Fair Ratio for the company is 20.66x, and the discount of the current P/E to this Fair Ratio leads the analysis to flag the shares as undervalued on this metric. The stock has a value score of 4 out of 6 on the platform’s checks.

American International Group (AIG)’s recent share price is around US$75.42, with a 3.4% gain over 7 days, but declines of 4.2% over 30 days, 10.5% year to date and 2.3% over 1 year. Over longer periods, the stock has risen 57.7% over 3 years and 81.3% over 5 years.

Using an Excess Returns framework, AIG’s Book Value of US$76.44 per share and Stable EPS estimate of US$8.94 per share, combined with an average Return on Equity of 10.20% and a Cost of Equity of US$6.12 per share, generate an Excess Return of US$2.82 per share. With a Stable Book Value assumption of US$87.69 per share, the model points to an intrinsic value of about US$166.86 per share, suggesting the stock is 54.8% undervalued relative to the recent price.

On a P/E basis, AIG trades on 13.03x earnings, above the Insurance industry average of 11.38x and a peer group average of 9.12x. Simply Wall St’s Fair Ratio is 12.46x, slightly below the current multiple, and this comparison leads the analysis to classify the shares as slightly overvalued on this metric. AIG holds a valuation score of 2 out of 6.

LVMH Moët Hennessy – Louis Vuitton Société Européenne last closed at €471.05, with a 3.4% gain over 7 days but a 6.2% decline over 30 days, a 26.6% decline year to date, a 9.0% decline over 1 year, a 39.8% decline over 3 years and a 12.6% decline over 5 years. Market discussion has focused on its position as a leading global luxury group and sensitivity to consumer demand and broader conditions.

A DCF analysis using a 2‑stage Free Cash Flow to Equity model starts from last twelve month free cash flow of about €13.1 billion and projects free cash flow of €12.1 billion for 2026 and €11.3 billion for 2035, discounted back to today. This results in an intrinsic value estimate of about €311.82 per share, implying the stock is 51.1% overvalued compared with the recent price under these assumptions.

LVMH currently trades on a P/E of 21.50x, above the Luxury industry average of 15.49x but below a peer group average of 47.95x. Simply Wall St’s Fair Ratio for the stock is 20.62x, and with the actual multiple slightly higher than this level, the shares are viewed as trading somewhat above the modelled valuation on the P/E approach. LVMH scores 2 out of 6 on the platform’s valuation checks.

Berkshire Hathaway (BRK-B)’s Class B shares recently traded around US$477, after rising 1.9% over 7 days but declining 4.3% over 30 days, 3.9% year to date and 3.3% over 1 year. Over longer periods, the stock is up 52.7% over 3 years and 79.4% over 5 years, reflecting its role as a diversified financial holding company.

An Excess Returns model, using a Book Value of US$498,663.02 per share and a Stable EPS of US$66,585.43 per share based on the median return on equity from the past five years, assumes a Cost of Equity of US$40,445.18 per share. This yields an Excess Return of US$26,140.25 per share and, together with a Stable Book Value estimate of US$545,417.94 per share, produces an intrinsic value of about US$798.38 per share. Relative to the recent price, the stock is assessed as roughly 67% undervalued on this framework.

Berkshire trades on a P/E of 15.39x, close to the Diversified Financial industry average of 15.79x and below a peer group average of 22.43x. Simply Wall St’s Fair Ratio of 16.57x exceeds the current multiple, leading the analysis to conclude that the shares appear slightly undervalued on the P/E metric. Berkshire scores 5 out of 6 on the platform’s valuation checks.
