This Is the No. 1 Reason I'm Buying and Holding the Vanguard Total Stock Market ETF (VTI) Right Now

Barclays raised its 2026 S&P 500 EPS forecast to $365 from $337 and its 2027 estimate to $414 from $389, citing AI-driven earnings strength, while setting a 2026 year-end index target of 7,950, about 4% above current levels. The article argues that more than $1 trillion of expected AI investment by the five largest technology companies will sustain broad corporate-profit growth, including a recovery in small-cap earnings, supporting continued gains for Vanguard Total Stock Market ETF. This bullish view is presented despite persistent inflation, rising Treasury yields, and an implied 90% probability of a September Fed rate hike.

Analysis

The investable implication is not broad-market beta but a widening dispersion between AI capex beneficiaries and companies funding that capex. Index-level earnings estimates increasingly embed sustained hyperscaler spending and fast conversion of AI investment into enterprise revenue; any evidence of weaker cloud backlog, lower GPU lead times, or a capex pause would hit the index through its concentrated mega-cap exposure before it is visible in aggregate earnings. VTI therefore offers less diversification than its breadth suggests, while its small-cap allocation is too limited to materially offset a de-rating in AI leaders.

Over the next 1-3 months, the key catalyst is earnings guidance: NVDA demand visibility, hyperscaler capex commentary, and software companies' ability to show AI-driven seat expansion rather than merely higher infrastructure expense. Rising real yields create an asymmetric risk because long-duration technology multiples can compress faster than consensus EPS upgrades arrive. A sustained upward move in the 10-year real yield alongside unchanged forward EPS would challenge the bullish index thesis.

The more attractive second-order opportunity is selective small-cap exposure only where AI lowers labor or servicing costs, rather than indiscriminate small-cap beta. Smaller firms with refinancing needs remain vulnerable to elevated rates, so broad small-cap participation requires both earnings delivery and easier financial conditions. The contrarian view is that optimistic published index targets have limited incremental informational value; positioning in the dominant AI complex makes upside dependent on further estimate revisions, not simply headline earnings beats.

Key Decisions for Investors

• Avoid adding broad VTI beta at current optimism; retain exposure only as a hedge-neutral core position and favor active dispersion over the next 1-3 months. Reassess if forward S&P 500 EPS revisions flatten for two consecutive weeks while 10-year real yields rise 25 bps.
• Maintain a tactical long NVDA versus short VTI pair through the next earnings cycle: NVDA remains the cleaner beneficiary if AI infrastructure budgets hold, while the short leg reduces market-duration risk. Size for a 10-15% relative-return target; exit if management signals material supply normalization or a sequential data-center revenue deceleration beyond normal seasonality.
• Do not treat small-cap upside as validated until refinancing-sensitive indices outperform on improving earnings revisions rather than falling yields alone. Use IWM as a watchlist proxy, not a long recommendation, until credit spreads tighten and small-cap forward EPS revisions turn persistently positive.
• For downside protection, buy 3-6 month QQQ put spreads rather than VTI puts if real yields continue higher: AI concentration makes QQQ the more direct multiple-compression hedge. Close protection if the 10-year real yield retraces materially or hyperscaler capex guidance is raised broadly.
