Monday, 20 July 2026 — EOD read. New week, same argument: the indices went two different directions on the surface and the same direction underneath. Here is what printed on our desk-flow tape.
- SPY slipped 0.16% to $742.09; QQQ faded a $705.80 morning high but still closed up 0.10%.
- Index tape leaned to puts (SPY 1.19, QQQ 1.21) while the market-wide ratio stayed benign at 0.81.
- Semis put premium stacked at SOXX $500 again; TSLA reports Wednesday — its $372.50 put line is the level to watch.
What happened
SPY opened at $747.06, bled through the session, and closed $742.09 — down 0.16% against Friday’s $743.29 close, finishing just off the $741.51 low. QQQ printed the mirror-image shape with a different ending: a morning push to $705.80 fully unwound, and the close at $696.06 still held a 0.10% gain over Friday. VIX eased to 18.65 from 18.77 after a 17.41 morning low — the round trip tracked the equity fade almost tick for tick. NVDA added 0.23% to $203.28.
The options tape split the same way. Market-wide, 35.6M calls traded against 28.7M puts — a 0.81 put/call with $18.1B in call premium versus $16.3B in put premium, a benign headline. The index lines told a different story: SPY ran a 1.19 put/call (7.16M puts vs 6.04M calls) with net premium -$36M, and QQQ ran 1.21 (4.43M puts vs 3.66M calls) with net premium -$43M. Single names carried the call volume; the index desks carried the puts.
Yesterday’s radar — OI confirm
Yesterday’s flagged prints, checked against this morning’s open-interest update — the tape’s own answer to whether the flow was real positioning. Thresholds: ≥40% of flagged volume became new OI = confirmed; 10–40% = partial; under 10% = not confirmed.
| Contract | Flagged | OI change overnight | Verdict |
|---|---|---|---|
| SOXX Aug 7 $550 puts | Friday (monetization watch) | +13 on 31 traded (42%) | Confirmed opening — small absolute size, but the volume became new OI |
| CVX July 24 $180 calls | Friday (continuing) | No row in this morning’s update | No data — the strike did not appear in the overnight OI file |
| QQQ Aug 21 $720 puts | Friday (the wall — roll/press watch) | −1,953 on 3,508 traded | Not confirmed — open interest fell; Friday’s volume was closing or rolling, not net new positioning |
The small semis hedge was real; the big one was an exit — the $720 wall thinned rather than thickened.
Why it matters
Three sessions running, the same pattern: a benign market-wide put/call sitting on top of index desks paying up for downside. Today added a third leg — SOXX put premium concentrated at the $500 strike across three expiries (July 31, August 14, and March 2027), roughly $10.8M of it filled at the ask. That is accumulation at one strike, not scattershot hedging. Meanwhile NVDA’s July 31 $200 call line traded 58K contracts in repeated waves, with the afternoon prints overwhelmingly hitting bids — traffic that reads as premium being unloaded into the line, not chased through it.
Our read: the semis strike-stacking is the dominant tell on today’s tape. QQQ’s failed $705.80 push and the 1.2 index put/calls sit consistent with it. The regime strip is unchanged — Bull · early, MPI 58 — so what printed today is a bull-regime tape hedging its tech exposure, not exiting it. The OI confirm above cuts both ways on that: Friday’s QQQ $720 wall turned out to be closing volume, which subtracts one brick from the bear case even as the semis hedging adds one.
What to watch into Tuesday
- SPY $741.51 — today’s low, and the level to watch. A close below would mark a second straight lower close; the $744 area (the 50-day) is the reference on the other side.
- QQQ $695.51 / $705.80 — the day’s rejection zone. A close back above $700 would mean the morning push was absorbed, not refused.
- NVDA $200 — 58K contracts traded on the July 31 $200 call line today. Tomorrow’s OI update will show whether that volume opened or closed; the strike is the near-dated shelf either way.
- TSLA $372.50 — earnings Wednesday postmarket. Today’s July 24 put prints at that strike ($2.0M, bid-side, 9.7x OI) are the pre-earnings positioning to check against the next OI update.
- SOXX $500 — the strike where put premium concentrated for a third session. A SOXX close below $520 would put the July 31 line within one weekly range of its strike.
- VIX 18.65 / 17.41 — the day’s range. A settle back under 18 would mark the equity fade as un-hedged noise; holding above it would not.
Names on our radar
Every row below is frozen at publication and scored mechanically in the Accountability Ledger at +5 and +21 sessions — misses stay on the page. Options prints are checked against the next morning’s open-interest update in the following session’s post.
| Ticker | What printed | Read |
|---|---|---|
| NVDA | 58K contracts on July 31 $200 calls in repeated waves; afternoon fills mostly hit bids | Heavy traffic at the $200 line reading as premium unloaded into it, not chased |
| SPY | July 28 $728 puts traded 19K vs 171 OI (112x), mixed bid/ask fills | A new short-dated downside line ~2% below spot; unconfirmed until tomorrow’s OI update |
| SOXX | ~$10.8M ask-side put premium across July 31 $500, Aug 14 $500, and Mar ’27 $500 | Third session of semis downside accumulation, all stacked at one strike |
| TSLA | July 24 $372.50 puts, $2.0M bid-side, 9.7x OI, ahead of Wednesday’s report | Put premium sold into earnings; the OI update will show if it was opening |
| SNDK | Oct $1500 puts and Sep/Aug $1500+ calls both active; $107.7M off-exchange block at $1390.95 | Two-way structure traffic around a round-number strike plus a late block — earnings 8/5 |
| UNH | Oct $430 calls, $2.2M swept at the ask, volume ~10x OI | Upside accumulation ~2% above spot in a name still far off its highs |
| AMAT | Jan ’27 $500 puts, $1.0M filled at the bid | Long-dated downside premium sold, not bought — reads as financing, not fear |
| IREN | $90.4M dark-pool block at $40.20, below the bid, on a 2.3x average-volume day | The largest single-name off-exchange print outside the megacaps today |
| RCL | $92.7M off-exchange block at $286.16, mid-range print | Quiet institutional transfer on a light-volume tape; no options echo |
The set-up
Monday’s tape was a fade that nobody panicked over: SPY lower, QQQ’s morning push refused, VIX round-tripping under 19, and the put traffic concentrated in exactly two places — near-dated index strikes and the SOXX $500 line. The OI confirm took one brick off the bear wall (QQQ $720 was closing volume) while today’s session added another (semis puts, third day, same strike). With the strip unchanged at Bull · early and MPI 58, the observation stands: this is a bull-regime tape paying for tech insurance while the market-wide ratio stays calm. Tuesday’s OI update on the NVDA $200 line and the SPY $728 puts is the next mechanical checkpoint, with TSLA’s Wednesday report the first real catalyst of the week.
Method note
Flow and dark-pool data sourced from Unusual Whales. MPI score and regime classifier are our internal composite; daily synthesis is AI-assisted from those inputs. Volume-over-OI activity is unconfirmed as new positioning until the next morning’s open-interest update; confirmations are published in the following session’s post. Index levels are EOD prints; put/call ratios are computed per ticker from that session’s volumes. The MPI snapshot in the strip is keyed to its own underlying date, shown separately when it differs from the session date.
