KEYS · Keysight Technologies, Inc.

The thesis

Keysight Technologies sells the test equipment that validates AI data-centre networks. Its orders still support the case, but the shares have not recovered the October breakout: they closed at $335.50 on 28 October 2026, 13.5% under the 52-week high of $388.03 (adjusted daily closes). The Q4 fiscal 2026 report, estimated for about 17 November 2026, settles whether revenue lands inside the $1.930B–$1.950B guide issued on 18 August 2026.

Since the 16 October 2026 note, the close has slipped from $342.08 (15 October 2026) to $335.50. The 14-day relative strength index, a momentum gauge where readings below 30 are called oversold, stands at 34.7. The three-month price change is 5.1%. The only company news in that period is a 6G research consortium membership (26 October 2026) and a test-solutions selection by the Korea Testing Laboratory (22 October 2026). Neither carries a financial figure, and no results or guidance have been issued, so the move is a price event and the business case is unchanged.

The narrative is maturing: the story is well known, Goldman Sachs raised its target to $487 on 5 October 2026, and the shares have still fallen about 13% from the record close of $384.64 on 2 October 2026. The rating stays at the level that marks coverage without a pick, because no new company fact since 16 October 2026 improves the odds and the next result is about three weeks away.

Bullish and bearish views on Keysight Technologies, Inc.

The bull case on Keysight Technologies, Inc. (KEYS), in brief: Orders at a record. The bear case: The breakout level is not recovered.

Bull case

• Orders at a record. Keysight's 18 August 2026 release reported fiscal Q3 orders of $2.091B, up 56% year over year, and revenue of $1.846B, up 36%.
• Guidance sits far above prior estimates. On 18 August 2026 Keysight guided Q4 revenue to $1.930B–$1.950B against a consensus of $1.814B, and adjusted EPS to $3.34–$3.40 against $2.70. The FY26 revenue guide rose to $7.095B.
• Margins expanded sharply. Fiscal Q3 operating margin was 33.2%, up 820 basis points year over year, with gross margin at 69.0% (Q3 FY26 earnings call, 18 August 2026).
• Analysts keep lifting targets. Goldman Sachs raised its Buy-rated target to $487 from $452 on 5 October 2026 (Financial Modeling Prep, a single-source report). Eight brokers raised targets on 19 August 2026, including UBS and Susquehanna at $440.
• Balance sheet supports delivery. The fiscal Q3 Form 10-Q shows cash of $2,605M at 31 July 2026 against total debt of $2,517M, and $520M of share repurchases in the nine months to that date.

Bear case

• The breakout level is not recovered. The close of $335.50 on 28 October 2026 is under the $350 level that marked the October breakout and 13.5% below the 52-week high, after a record close of $384.64 on 2 October 2026.
• Valuation was already full. MarketBeat showed a trailing price-to-earnings ratio of 51.39 and an average target of $392.83 on 1 October 2026, only slightly above the record close.
• Insiders sold into the rally. CEO Satish Dhanasekaran sold 3,000 shares at $364.13 ($1,092,390) on 30 September 2026 and directly holds 118,390.578 shares afterward (Investing.com, from the SEC Form 4). MarketBeat counted 9,200 shares sold by insiders over 90 days to 1 October 2026.
• Contracted backing is thin. The fiscal Q3 Form 10-Q reports about $616M of remaining performance obligations across 2026–2028, against $2.091B of orders in one quarter.
• Good news has sold off before. After the 18 August 2026 results the shares closed at $319.45 on 19 August 2026, down 6.3%, despite eight target increases.

Price setup

The last close is $335.50 (28 October 2026), 13.5% below the $388.03 52-week high and well below the $384.64 record close of 2 October 2026. The 14-day relative strength index of 34.7 sits just above the oversold line, so selling pressure is heavy but not yet extreme.

On 1 October 2026 MarketBeat put the 50-day average at $332.11 and the 200-day average at $330.09. The shares now trade close to that zone. Those averages were measured four weeks ago and will have shifted. The next reference below is the 19 August 2026 post-earnings close of $319.45, which is also where the invalidation level sits.

Crowding evidence has eased from early October, when the relative strength index reached 94.8. Three observations remain: the CEO's Form 4 sale at $364.13 on 30 September 2026, a trailing price-to-earnings ratio above 50 (MarketBeat, 1 October 2026), and an earnings date within three weeks. No filings were recorded for Keysight in the past 30 days.

Catalysts, next 30 days

• ~17 November 2026, est. Q4 FY26 and full-year results. Earnings Whispers lists 17 November 2026 after the close; another calendar projects 23 November 2026. Keysight has not confirmed either. The report tests the revenue guide, the $3.34–$3.40 adjusted EPS guide, whether orders hold above $2.0B and whether the parts constraint eases into FY27.
• Hyperscaler spending commentary. Microsoft, Meta, Alphabet and Amazon report in late October. Their 2027 capital spending signals underwrite demand for network-test orders. Alphabet's finance chief said in July that 2027 capital spending should increase significantly again, with no figure given.

Elapsed catalysts

• 31 October 2026 — fiscal year-end. Closes the quarter guided to $1.930B–$1.950B of revenue. Keysight has no disclosure scheduled before the report. (passed 6d ago)

What would change the view

The case breaks if Q4 FY26 revenue comes in under the $1.930B low end of guidance, if orders fall back below $2.0B, or if management repeats the incoming-parts language while guiding FY27 growth below the FY26 rate. A lower 2027 capital spending signal from any of the four large cloud companies would weaken the demand side.

On price, a daily close below $319, just under the 19 August 2026 post-earnings close of $319.45, would end the case. The case would strengthen on a Q4 revenue result above $1.950B with remaining performance obligations rising in the FY26 Form 10-K, and on a close back above $350.

What it trades with

Keysight trades with the AI data-centre build-out through its network-test and validation business. Hyperscaler capital spending guidance and the large AI-chip and optical-component names are the nearest read-throughs. Orders are the leading indicator, but management cited incoming parts as a constraint on 18 August 2026, so order strength and recognised revenue can diverge for several quarters.

The shares fell about 13% from 2 October to 28 October 2026 with no company-specific negative news in Keysight's own releases. That points to sector-wide or momentum-driven selling. Peer price data is not included here, so the note draws no conclusion on which.
