The Record

Every dated forward call, graded against the falsifier it was published with — not against how it reads in hindsight. Each claim carries a header, a horizon (when it resolves), a falsifier (what would prove it wrong), and a confidence band. A call is graded blind against that falsifier: a claim can be right for the wrong reason and still count as a hit, and where that happened it is said so in the resolution. Open claims stay listed until their horizon clears, and a claim that passes its horizon ungraded is a failure of this page, not a pending result. Machine-readable twin: /data/scorecard.json.

Jun 26, 2026	Dell's non-GAAP gross margin holds at or above 18% in the Q2 FY27 print and sets no new trailing-twelve-month low — operating leverage keeps outrunning AI-mix margin erosion. Horizon by September 15, 2026 · Falsifier Q2 FY27 non-GAAP gross margin prints below ~18% AND below the Q1 FY27 level (18.1%). Resolved Sep 1, 2026. Q2 FY27 (quarter ended Jul 31, 2026; reported Sep 1, 2026): non-GAAP gross margin 21.1%, against 18.7% a year earlier and 18.1% in Q1 FY27; GAAP 20.9% against 18.3%. Neither leg of the falsifier fired - the print was not below ~18%, and not below Q1's 18.1% - and it set no new trailing-twelve-month low, which remains Q1 FY27's 18.1%. Graded blind against the written falsifier, which it passed. The mechanism named in the call was only half right: operating margin did expand to 11.5% from 6.0%, but gross margin rose mainly because the AI share of revenue FELL about 190bps to 34.92%, not because operating leverage absorbed a rising AI mix. Right answer, partly wrong reason - recorded here rather than quietly claimed, and the reasoning is corrected in the Dell Q2 FY27 deep dive.	MEDIUM 40-70%	HIT
Jun 3, 2026	2 of {MasTec, EMCOR, Comfort Systems, Sterling} report DSO extension >5 days QoQ on Q2 prints Horizon by August 31, 2026 · Falsifier All four names maintain or compress DSO on their Q2 prints Resolved Aug 31, 2026. All four names had reported Q2 2026 by the Aug 31 horizon. DSO computed as period-end net receivables divided by quarterly revenue, times days in quarter: MasTec 91.0 -> 88.0 (-3.1 days), EMCOR 95.8 -> 97.1 (+1.3), Comfort Systems 99.9 -> 94.8 (-5.1), Sterling 71.2 -> 72.8 (+1.6). Zero of four extended by more than 5 days and two compressed; the call needed 2 of 4 and got none. The construction pipeline's own Q2 sweep reached the same verdict independently and retired the instrument: no Tier-1 working-capital stress event appeared anywhere in the 90-day evidence stream, and the strain that did surface was a $337M execution charge at AECOM. The binding constraint in this cycle is labour productivity, not customer payment behaviour, so cash conversion was the wrong place to look. Graded 2026-09-06, 6 days after its own horizon.

May 27, 2026	Q2 2026 DRAM settlement comes in below the published guidance band Horizon by July 15, 2026 · Falsifier Q2 DRAM settlement prints inside the published guidance band Resolved Jul 15, 2026. Wrong, and in the opposite direction. The call was that the Q2 2026 DRAM settlement would print BELOW the published guidance band as phantom distributor demand unwound. Q2 contract prices instead rose roughly 60% quarter on quarter, the largest single-quarter increase of the cycle, and suppliers carried it into Q3: Samsung sought as much as 20% more on average DRAM selling prices, SK Hynix removed the ceilings from its long-term supply agreements, and both described HBM, DRAM and NAND capacity as essentially sold out for 2026. Graded MISS rather than PARTIAL: the settlement did not print below the band, and it did not print inside it either. The demand-refusing-a-price mechanism the call was built on did eventually appear, but in the RATE of increase in 3Q26 and attributed to consumer-electronics makers refusing another rise - not to the phantom-inventory unwind, and not inside the window. Graded 2026-09-06, 53 days after its own horizon; that delay is a failure of this scorecard, not of the call, and it is written up in Machine Room No.006.	MEDIUM 40-70%	MISS

Q2 2026 DRAM settlement comes in below the published guidance band

Horizon by July 15, 2026 · Falsifier Q2 DRAM settlement prints inside the published guidance band

Resolved Jul 15, 2026. Wrong, and in the opposite direction. The call was that the Q2 2026 DRAM settlement would print BELOW the published guidance band as phantom distributor demand unwound. Q2 contract prices instead rose roughly 60% quarter on quarter, the largest single-quarter increase of the cycle, and suppliers carried it into Q3: Samsung sought as much as 20% more on average DRAM selling prices, SK Hynix removed the ceilings from its long-term supply agreements, and both described HBM, DRAM and NAND capacity as essentially sold out for 2026. Graded MISS rather than PARTIAL: the settlement did not print below the band, and it did not print inside it either. The demand-refusing-a-price mechanism the call was built on did eventually appear, but in the RATE of increase in 3Q26 and attributed to consumer-electronics makers refusing another rise - not to the phantom-inventory unwind, and not inside the window. Graded 2026-09-06, 53 days after its own horizon; that delay is a failure of this scorecard, not of the call, and it is written up in Machine Room No.006.
