October 13 Recap: Leaned Bearish, MU $3.0B Bearish, SPX GEX Positive

Written by

$16.9B in single-name premium, 22% bullish versus 24% bearish. MU led at $3.0B Bearish; SPX GEX was +$103.41B.

This edition reads TradingFlow’s Daily Market Recap for October 13, 2026, captured on October 14. Premium, IV, and GEX figures agreed across two runs; Step 7 changed its leading-mover key. This is a completed-session report, not a trade recommendation.

Keep two clocks separate: premium, sentiment, and prints describe the session tape; GEX and IV are the recap’s T+1 / prior-close snapshots. This historical recap is not a live intraday gamma map.

$16.9B, 59% calls, 22% bullish versus 24% bearish. MU led at $3.0B Bearish; SPX net GEX printed +103.41B, Positive.

What the recap printed

October 13 session KPI strip

Test app, session 2026-10-13, KPI. Captured October 14, 2026.

Sentiment bars: Neutral $9.1B, Bullish $3.8B, Bearish $4.0B. Call share is option type, not bullish sentiment. Neutral premium supplies no direction; rounded buckets need not sum exactly to the rounded KPI total.

MU’s $1.6B in puts exceeded its $1.4B in calls. MU was Bearish; META, SNDK, AMD, and MSFT were Mixed, while NVDA was Bullish. Option type and sentiment remain separate fields.

The bottom line and glance show MU $3B; the leaders table and headline cards show MU $3.0B. Preserve these field readings rather than reconciling them into a new number.

October 13 bottom line and glance

Test app, session 2026-10-13, Bottom line / glance. Captured October 14, 2026.

Exposure and volatility context

The glance lists ORCL +0M shares-equiv. as largest Net DEX and META 136% as largest Net DEI magnitude. Step 4 prints META 136%, with Negative Net DEX. DEI is an unsigned activity-relative magnitude; DEX provides a separate signed classification. Neither proves opening intent or actual dealer inventory.

ORCL’s +0M shares-equiv. Net DEX reading rounds to zero; it does not support a directional inference. META’s Mixed flow tag and Negative DEX classification describe different measures.

Step 5’s highest IV rank among active names is GS 59 / 100, with 31.2% 30-day implied volatility. This is snapshot volatility context, not realized session volatility.

Index GEX: SPX Positive

October 13 index GEX backdrop

Test app, session 2026-10-13, Step 6 · T+1. Captured October 14, 2026.

IndexNet GEX ($B)Regime
SPX+103.41Positive
IWM−2.31Negative
NDX−1.63Negative
QQQ−0.92Negative
SPY+0.60Positive
DIA+0.06Positive

SPX, SPY, and DIA were Positive; IWM, NDX, and QQQ were Negative. The large positive SPX reading did not describe every index book.

GEX describes modeled chain structure under TradingFlow’s dealer-sign convention. The regime does not establish observed dealer inventory, a support level, a pin target, or the next session’s direction.

Headline name: MU at $953

MU headline cards for October 13

Test app, session 2026-10-13, Step 8. Captured October 14, 2026.

Cards: last $953, premium $3.0B, 46% calls, 15% bullish, 70% average IV on traded contracts. The headline name is selected by premium, not by the largest price move.

MU biggest prints for October 13

Test app, session 2026-10-13, Step 8 · prints. Captured October 14, 2026.

The largest listed ticket was 12:56 1,200 CALL, expiry 2026-12-18, premium $17M, tagged NEUTRAL. The two largest listed prints were Neutral calls at 12:56 with different strikes and expiries. Two 13:39 puts at the same strike and expiry appear as separate Bearish tickets. Shared timing does not establish one order or one trader.

Ticket tags do not prove who bought or sold, whether a position opened, or whether adjacent prints form a single strategy.

Movers: PDSB +10.4%

October 13 intraday movers, second run led by AREC Down

Test app, session 2026-10-13, Step 7 · second run. Captured October 14, 2026.

Bottom line: PDSB +10.4%. Step 7 first run: PDSB +10.4%, Up; second run: AREC −10.2%, Down. The screenshot above preserves the second run. Keep these separate readings. The bottom line names the largest gain; Step 7’s key can select a gain or loss across runs.

The intraday_pct reading is a first-to-last underlying-price proxy in the option tape. It is not an independently verified daily stock return, and movers do not prove flow causality.
