Growth Stocks Still Cheap Despite S&P 500 Near Record Price-to-Sales Valuation

The S&P 500 is trading near a record high on a price-to-sales basis, yet a subset of individual growth stocks remains inexpensive on the same metric, creating a bifurcation that value-oriented investors can exploit selectively. The argument that specific growth names are cheap when the index itself is expensive is a classic sector-within-market relative value trade — identifying companies whose revenue growth trajectories and addressable market expansions are not yet reflected in their current valuations relative to slower-growing index constituents. Price-to-sales as a valuation frame is particularly relevant in the current environment where earnings estimates for high-growth technology companies remain wide-range due to AI monetisation uncertainty.

The market implication of this thesis is that the broad 'stocks are expensive' narrative obscures significant dispersion at the individual security level. Passive index investors paying record P/S multiples are doing so because index-heavyweights like Apple, Microsoft, and Nvidia have driven the aggregate ratio up, while smaller growth companies that are not yet index-heavyweights trade at much lower multiples. Active fund managers with growth mandates are likely to use this framing to justify overweighting specific names that offer revenue growth at a reasonable price, particularly heading into a Q3 earnings season where any upside surprise in growth company revenues could narrow the valuation gap rapidly.

Key variables for investors evaluating the 'growth stocks cheap' thesis include the revenue growth rate sustainability of the specific companies cited, the trajectory of the US 10-year Treasury yield (which inversely affects growth stock discount rates), and whether the broader S&P 500 P/S ratio at record levels is a mean-reversion signal or structurally justified by AI-driven productivity improvements. Any deceleration in index-heavyweight revenue growth would compress the index P/S ratio from the top, potentially validating the rotation thesis toward cheaper growth names before the end of the year.
