Reading the market regime before prices move
Reading the market regime before prices move
Every number here is computed from the traded YUM options chain. The call wall is where dealer hedging accumulates above spot and caps upside, the put wall is its mirror below, and the gamma flip is the level where hedging stops damping moves and starts amplifying them.

السعرُ 150.71 يعلو نقطةَ الانقلاب 144.82 بفارق 4.07٪، مسافةٌ مريحة. Positioning is clearly positive: dealer hedging buys dips and sells rallies, so price tends to grind within a range rather than jump. Flipping this state يحتاج هبوطاً يتجاوز 4.1٪، أي أنّه ليس سيناريو الجلسة الأقرب. Price is inside the range between 145.00 and 160.00, closer to Put wall of the two.
أكبرُ تجمّعٍ لعقود الشراء عند 160.00 (6.16% from price)، ولعقود البيع عند 145.00 (-3.79% from price)، والمسافةُ بينهما 10.34٪، a **wide** range. That does not imply a move is coming, only that the walls are far enough apart not to confine YUM during the session, so flow leads rather than hedging.
صافي تعرّض الغاما لـYUM يبلغ 1.29 مليون، وهو حجمٌ محدود. Hedging for a 1% move is about 8,586 shares. In this range hedging stays secondary to the stock's own flow, so the levels below should not be asked to carry more than they can.
and this reading is built on 106 contracts in the chain.
Over the last 27 days of tracking (293 archived snapshots), YUM stayed above the gamma flip in 52% of readings، وتنقّلت نقطةُ الانقلاب نفسُها بين 143.42 و153.39، أي بنطاق 6.95٪، وهو ما يعني أنّ the level moves with the market and does not serve as a fixed reference across days.
