Four of the eight big listed firms that sell corporate technology work — building software, running back offices, staffing projects — cut their full-year revenue forecasts this summer. One raised its profit forecast. Between mid-July and mid-August the shares of all eight went up together, by about 20% on average, and the size of each move bore almost no relation to which side of that line the company was on.

The two biggest gainers, Cognizant and Accenture, are the two with the better delivered numbers, yet both still sit below their longer-run averages after brutal falls earlier this year. Accenture traded as high as $288.54 in 2026 and as low as $124.44 — a 57% peak-to-trough drop — so even a 31% bounce leaves its trend measures pointing down. That is arithmetic about how far each fell, not a judgment on any of these businesses.

Who actually delivered

Cognizant, a New Jersey outsourcer with 356,700 employees running technology and business processes for banks, insurers and healthcare firms, is the one that raised. On 29 July it lifted 2026 adjusted earnings guidance to $5.70–$5.82 a share, from a prior 7–9% growth range, reporting revenue up 4.5% to $5.48bn. Trailing bookings reached $29bn, up 5%, with seven deals above $100m of contract value. It bought back $1.1bn of stock in the quarter and is on pace for roughly $2.6bn this year — more than a tenth of its market value.

Accenture, the Dublin-headquartered consultancy employing 799,000 people, grew revenue 5.6% to $18.72bn in the quarter to 31 May, with operating income up 6.5% and margin steady at 17.0%. Its trailing free-cash-flow yield of 11.6% is the highest of the eight. The blemish is the order book: bookings fell 2%, and it trimmed its revenue outlook.

CGI, the Montreal IT and business-process firm with 94,000 staff serving governments, banks and utilities, is the outlier on hiring — recruitment is up 50% year on year while most peers shrink. Revenue rose only 2.5% to $4.19bn and organic growth was roughly zero once acquisitions are stripped out, but it booked $4.2bn in the quarter and closed with backlog of $31.8bn, about 1.9 times annual revenue. Management says it sees no broad pullback in discretionary spending.

Grid Dynamics, a San Ramon engineering shop of 4,838 people building digital platforms for Fortune 1000 retailers and telecoms, grew revenue 7% to $108.2m with gross profit up 14.8% — the fastest in the group — and raised third-quarter guidance. Work it classes as AI passed 30% of revenue. It did that while cutting headcount 3%.

Who did not

EPAM, the Pennsylvania software-engineering firm with 62,850 staff, showed the cleanest operating leverage of the eight: revenue up 4.5%, gross profit up 10.3%, operating income up 20.4%. Then on 6 August it cut full-year revenue growth to 3.2–4.2%, with Americas revenue up just 0.5% against Europe's 10.9%, and pushed its large-deal pipeline into 2027. The shares fell 14.5% that session and still finished the month higher.

Globant, the Luxembourg-domiciled builder of AI-integrated software with 28,510 employees, reported revenue of $614.4m, flat year on year, with gross profit down 4.3% and net income of $1.8m. It reduced full-year revenue guidance to $2.43bn–$2.46bn, blaming Saudi budget cuts, weak travel spending and slower North American decisions. Its own AI product line is running at $52.8m of annualized revenue, about 2% of the total.

Infosys, the Bengaluru firm with 328,062 employees, cut fiscal 2027 constant-currency guidance to 1.5–3.0% growth — roughly half a point organic once acquisitions are excluded — and management confirmed outright pricing "deflation" on renewals, with clients now demanding productivity savings mid-contract. It is nonetheless hiring 20,000 graduates. Wipro, its 240,000-employee neighbor, reported IT services revenue of $2.61bn, down 1.2% from the prior quarter, and guided to another sequential decline, with margin off 120 basis points to 16%.

This is not company-specific. HCLTech's leadership sees 2–3% annual price deflation in traditional services, and the industry body NASSCOM's president Rajesh Nambiar has put it plainly: "A headcount-based model assumes that value scales with effort, but AI fundamentally challenges that premise."

What the prices assume

Because gross margins here run from 16% at CGI to 37% at Grid Dynamics, price-to-sales tells you little; price per dollar of trailing gross profit is comparable. On that measure the order is Globant 2.04x, EPAM 3.30x, Cognizant 3.82x, Grid Dynamics 4.29x, Accenture 4.63x, CGI 6.50x, Wipro 6.60x and Infosys 8.07x. The firm that raised guidance is third-cheapest; the firm conceding price cuts is the most expensive, and also trades at 5.18x book against Globant's 0.76x.

Infosys is the only one of the eight whose forward earnings multiple (15.2x) exceeds its trailing (14.9x) — consensus expects earnings to go nowhere. EPAM has the widest gap the other way, 13.6x trailing against 7.7x forward. Accenture's 12.8x forward compares with a five-year year-end range of 21x to 37x. Grid Dynamics is the expensive one: 14.4x trailing EV/EBITDA against 6.4x–9.7x for the rest, on quarterly operating income of $1.28m.

Seven of the eight are still cheaper per dollar of gross profit than in mid-February; only Grid Dynamics has re-rated upward, and it is the only member trading above its 200-day average. Seven recorded their single best session between 27 and 30 July, when a selloff in chip stocks pushed money toward firms that build no AI hardware. Strip each name's two largest sessions and the 20% month becomes 0.3%.

The setup

Where it stands — Eight IT services firms rallied together in a rotation; only Cognizant, CGI and Grid Dynamics reported businesses that improved. Would confirm — Cognizant delivering full-year adjusted earnings within $5.70–$5.82 with a seventh straight quarter of margin expansion. Would invalidate — Cognizant or Accenture bookings turning negative year on year, putting the guidance raise beyond reach. Watch next — Accenture's fiscal fourth-quarter results in late September, the first read on whether bookings stop shrinking. Valuation — Cognizant 12.6x trailing and 10.2x forward earnings; Infosys 14.9x trailing versus 15.2x forward, the only inversion of the eight.
