Gross margins are rolling over, but net margin expectations remain high
Report by Trivariate Research
Median gross margins for the Top 500 peaked at 46.4% in Feb 25 and have since fallen to 44.9% in Jan 26, yet bottom-up forecasts imply continued strong net income growth - likely reflecting embedded AI-driven productivity assumptions. Historically, Trivariate finds valuation multiples correlate more closely with gross profit growth than net income growth, implying further multiple expansion will require renewed gross margin strength or a structural shift in how markets reward earnings. Their quantitatively derived longs (e.g. Merck, T-Mobile, McDonald’s) have had recent multiple expansion and are forecasted to have margin expansion, but not more net margin than gross margin expansion. While shorts (e.g. Amphenol, Salesforce, Arista Networks, Las Vegas Sands) screen for gross margin contraction but net margin expansion, reducing estimate achievability.
