The Momentum Is Real. So Is the Structure Beneath It.

Two stocks that lit up screens in August 2026 share almost nothing on the surface. One is a defense technology contractor deploying agentic AI for the U.S. Intelligence Community. The other is a global research and advisory firm engineering an aggressive buyback to shrink its share count while contract value slowly reaccelerates. What connects CACI International (NYSE: CACI) and Gartner (NYSE: IT) is the same thing that separates momentum trades from compounding positions: both have durable earnings mechanics that outlast the catalyst that put them on the radar.

That distinction matters in an environment where the S&P 500 is demanding near-perfect execution to justify elevated multiples, and where a single guidance miss can erase months of gains in a session. Long-term investors need to understand not just whether these stocks have moved, but why they will continue to compound through the cycle. The numbers tell two different but equally instructive stories.

Why the Macro Moment Favors These Two Names

As of mid-August 2026, the macro backdrop is doing two contradictory things simultaneously. The July jobs report delivered a net loss that collapsed the 12-month payroll average sharply lower, pulling September rate cut odds higher with it. At the same time, the S&P 500 Shiller CAPE ratio is near its highest level in over 25 years, with investors crowding into earnings compounders as a defensive growth alternative to pure cyclicals. Equity redemptions from mutual funds have been elevated, while institutional ETF flows remain constructive, a bifurcation that historically favors high-conviction single-name positioning over passive exposure.

Within that context, defense technology and enterprise research advisory businesses occupy an unusual position: revenue visibility is structurally higher than in most sectors, contract cycles are long, and demand is not directly correlated with the consumer credit cycle. That insulation becomes a premium in a slowing jobs market. Neither CACI nor Gartner is immune to macro headwinds, but both generate free cash flow at scale and have levers to protect per-share earnings even when top-line growth moderates.

Where the Capital Is Moving and Who Captures It

Defense technology is absorbing capital at an accelerating rate. The integration of agentic AI into intelligence operations, space-based surveillance, and geospatial analysis is no longer a future project. It is a live procurement priority, visible in contract awards and growing funded backlogs across the sector. CACI sits near the center of that shift. The company competes with larger primes on technology differentiation rather than size, a strategy that has produced consistent margin expansion while maintaining organic revenue growth in the high single digits.

Enterprise research advisory is a different sector, driven by the pace of corporate technology decision-making rather than government appropriations cycles. Gartner’s business depends on executives paying annual subscriptions to access research, benchmarks, and advisory access. In a macro environment where AI is simultaneously creating uncertainty and driving urgency, executives are leaning into that kind of external validation more, not less. The risk is that budget scrutiny slows renewal cycles. The opportunity is that no macroeconomic environment in the last 20 years has sustained a prolonged contraction in Gartner’s contract value. The current low-single-digit year-over-year contract value growth is a floor more than a ceiling.

Reading the Numbers Behind the Rally

CACI International (NYSE: CACI)

CACI’s fiscal year 2026 results, released August 6, were unambiguous. Full-year revenue reached $9.57 billion, up 10.9% year over year, with organic growth of 7.2%. Q4 alone produced 17.6% revenue growth year over year, driven by 11.6% organic expansion. Adjusted EPS of $29.83 for the full year grew 12.7%, and free cash flow of $735 million represented a step-change in cash generation that most defense contractors can only gesture at.

The ARKA acquisition, completed March 9, 2026 for $2.6 billion in cash, is the strategic move that changes CACI’s addressable market rather than just its revenue run-rate. ARKA brings electro-optical/infrared and hyperspectral imaging capabilities alongside agentic AI-based software for geospatial intelligence, assets that directly serve the Intelligence Community and U.S. Space Force. ARKA also holds an additional $2 billion in non-competitive franchise programs not yet recognized in backlog due to regulatory timing. That revenue will arrive. The question is only when.

The funded backlog grew 28.6% year over year. Total backlog sits above $32 billion. Fiscal 2027 guidance projects revenue between $10.65 billion and $10.85 billion, with EBITDA margin in the high 12% range and free cash flow of at least $900 million. Adjusted diluted EPS is expected between $32.96 and $33.86. The average analyst price target sits near $616.50, implying meaningful upside from current levels near $552.

CACI’s Q4 adjusted EPS of $8.91 beat the consensus estimate of $7.26 by 22.7%. Full-year EBITDA reached approximately $1.17 billion, up 21.4%, with an EBITDA margin of 12.3%, up 110 basis points from the prior year. The debt load at 3.7 times pro forma at quarter-end is elevated following the ARKA acquisition, but management has signaled a focused path to reduce it. The OTA award value in fiscal 2026 more than doubled the combined value of fiscal 2024 and 2025, reflecting the government’s increasing preference for non-traditional procurement channels that favor agile, technology-first vendors.

Gartner (NYSE: IT)

Gartner’s Q2 2026 results are better than the headline revenue figure suggests. Reported revenue declined about 1% year over year to roughly $1.7 billion, but that decline reflects the divestiture of the Digital Markets operation. Adjusted EPS of $4.37 beat the consensus estimate of $3.77 by 15.9% and grew 23.8% year over year.

Below the revenue line, the outlook is considerably more compelling. The mechanism behind that EPS expansion is Gartner’s buyback, which removed more than 5% of the fully diluted share count sequentially in Q2 alone, with $547 million deployed in a single quarter. The board approved an additional $500 million of share repurchase authorization in July 2026. Full-year 2026 free cash flow guidance is at least $1.19 billion, a capital efficiency metric that supports the pace of repurchases.

Contract value, the business’s leading indicator, is accelerating in the right direction. Total foreign-currency-neutral contract value reached $5.28 billion at June 30, up 1.7% year over year. Ex-Federal contract value grew 3.3%, signaling that the drag from the federal government spending environment is the primary constraint on total CV growth, not commercial weakness. Management targets compound annual adjusted EPS growth above 12% over the next three years. Full-year 2026 adjusted EPS guidance is at least $14.00, raised from $13.25 at the prior guidance update.

Gartner’s 52-week range of $124.25 to $265.85 illustrates the severity of the drawdown and the scale of the partial recovery. The stock remains well below its all-time closing high of $551.80 from November 2024. A GF Score of 84/100 and a GF Value estimate implying 60% upside capture the fundamental disconnect between the business’s earnings power and its current market price. Gross margin in Q2 reached 69.6%, consistent with the durable characteristics of a subscription-driven research business.

Levels That Matter Right Now

CACI’s chart structure after the August 6 earnings release is constructive. The stock rose 6.66% to $552.54 on the session, and the 52-week range of $434.70 to $683.50 places current levels in the lower half of the distribution. The 50-day moving average has been rising consistently since March 2026. Volume on the Q4 report day was roughly 1.3 times the average, consistent with institutional accumulation rather than a retail-driven spike. The beta of 0.59 makes CACI a lower-volatility vehicle for defense exposure, useful in a market where the VIX has been elevated by geopolitical and rate uncertainty. Key support sits near the $497 level where the stock consolidated in late July. Resistance from the prior range high near $683 defines the upside scenario.

Gartner’s technical structure is more complex. The stock surged 27.5% in the week following Q2 results, and 45% over the prior month, but remains in a multi-month recovery from the sub-$130 lows reached earlier in 2026. The 200-day moving average has been declining, and the stock is only recently beginning to trade above it. That is both a risk and an opportunity: sustained trading above the 200-day would signal the start of a genuine trend reversal rather than a short-lived bounce. The $194 level, tested briefly in the week of August 10, represents near-term resistance from the prior consolidation range. Support has built near $178.

Three Ways This Plays Out

Bull Case

For CACI: The ARKA non-competitive franchise programs ($2 billion) begin meeting regulatory recognition criteria in fiscal 2027, adding a layer of revenue growth not currently embedded in consensus. New OTA awards continue at twice the historical pace, the book-to-bill sustains above 1.0, and debt load declines to below 3.0 times within two quarters of the fiscal year end. At 18 times forward earnings on $33.41 midpoint EPS, CACI approaches the $600 level. For Gartner: Ex-Federal CV growth accelerates to 5% or above by Q4 2026 as enterprise technology budgets firm following macroeconomic stabilization. The share count, already below 64 million fully diluted, continues to shrink. At 20 times $14.00-plus EPS guidance, the stock reclaims the $280 range.

Base Case

CACI executes on its FY2027 revenue midpoint of $10.75 billion, delivers free cash flow of $900 million, and reduces its debt load by roughly 0.75 turns by June 2027. EPS lands near the $33.40 midpoint of guidance. The multiple holds near 17 times forward earnings, placing the stock near $568. Gartner’s total CV growth reaches 3% by year-end, consistent with management’s directional guidance. Buybacks continue at $400 to $500 million per quarter, driving per-share earnings above $14 for the full year. The stock consolidates between $185 and $220.

Bear Case

CACI faces a budget continuing resolution or a delay in government appropriations that pushes $750 million or more of anticipated awards into fiscal 2028. ARKA integration costs prove stickier than guided. The debt load fails to decline materially, and the market begins applying a discount to the multiple for financial risk. The stock revisits the $450 level. For Gartner: Global IT budget pressure intensifies through late 2026, contract value growth stalls at or below 1%, and GBS new business declines accelerate. The buyback continues but cannot offset revenue deceleration. The stock tests the $150 to $160 support zone.

How to Position Without Getting Caught Chasing

CACI is not a momentum trade. With a beta of 0.59 and a business driven by multi-year contract cycles, it rewards patient positioning rather than tactical entries. Traders sizing into CACI should watch the funded backlog metric quarterly. A funded backlog below $4.7 billion would signal slowing contract conversion and is a natural risk trigger. The debt ratio is the second variable to monitor: declining from 3.7 toward 3.0 times on schedule confirms the ARKA integration is not dragging free cash flow below guidance. Options implied volatility on CACI has historically been modest, making defined-risk structures less efficient than direct equity exposure for longer time horizons.

Gartner requires a different framework. The stock has been volatile, and the technical structure is still in early recovery. Positioning discipline matters here more than with CACI. A defined entry range between $178 and $190 captures the current support zone without chasing the post-earnings spike. The key metric to monitor each quarter is ex-Federal CV growth: any acceleration above 4% would signal the BTI transformation is translating into tangible retention and expansion improvement. Traders with shorter horizons should note that Gartner’s next earnings event will face cleaner comparisons following the Digital Markets divestiture, which could produce a reported revenue growth figure that surprises the street given the noise in prior-year comparisons.

For both names: Position sizing should reflect the macro uncertainty embedded in a rate environment where the September decision remains live. A weaker jobs market and a 3.4% CPI reading have reduced but not eliminated the probability of further tightening. Neither CACI nor Gartner is immune to a broad equity de-rating if long yields rise materially from current levels.

What the Math Says When You Zoom Out

The case for both CACI and Gartner is built on compounding mechanics, not on a single quarter’s result. CACI is converting a generational defense modernization cycle into funded backlog, free cash flow, and margin expansion, while the ARKA acquisition adds capabilities in space-based intelligence that carry high technical barriers to replication. Gartner is engineering per-share earnings growth through a combination of buybacks at scale, CV acceleration, and margin discipline, even as the reported revenue line looks deceptively flat following a voluntary divestiture.

Neither stock is without risk. CACI carries acquisition debt that must be reduced. Gartner carries the risk that CV reacceleration is slower than management’s three-year targets imply. Both risks are knowable, measurable, and monitored each quarter. That is the kind of risk a disciplined long-term investor can underwrite. The kind that cannot be underwritten is the unknown. On that score, both companies are well-structured: durable contracts, predictable cash generation, and management teams with multi-year track records of execution.

Preparation, not prediction. Know the metrics, watch the levels, and let the compounding do the work.
