What is the UMBF options turnover ratio?

As of May 29, 2026, UMBF turnover ratio is 0.26 (167 contracts traded against 633 contracts outstanding). A turnover ratio below 0.5 is typical maintenance flow against existing positions.

Where is UMBF open interest concentrated?

Gamma concentration is 0.36: open interest is more distributed across strikes, reducing any single-strike pinning force. The full per-strike open-interest distribution is visible in the chain view.

Why does volume-open-interest matter for UMBF options?

Volume tells you what is being traded today; open interest tells you what was already there. The combination separates opening flow (today's volume building new positions) from closing flow (today's volume unwinding existing ones), and locates the strikes that carry hedging-driven support or resistance based on dealer-gamma concentration.

As of May 29, 2026, UMB Financial Corporation (UMBF) has 167 contracts traded today against 633 contracts outstanding. Open interest breaks down as 553 calls and 80 puts. Turnover ratio is 0.26: typical maintenance flow relative to existing positions. Gamma concentration is 0.36: open interest is more distributed across strikes.

How UMBF volume & open interest Data Feeds Strategy Selection

Strategy selection on UMB Financial Corporation options does not derive from any single metric in isolation. The volume & open interest view above sits inside a broader read: ATM IV currently sits at 25.6% and dealer gamma exposure is positive, so dealer hedging is mechanically mean-reverting. Combine the volume & open interest data here with the volatility-skew surface, dealer-gamma exposure, max-pain level, and upcoming-events calendar to build a positioning thesis. Risk-defined structures (credit spreads, debit spreads, iron condors) are usually safer than naked positions while the regime is uncertain; the data on this page anchors the inputs but does not by itself constitute a trade thesis.

How to read the UMBF volume and OI data

The two-panel chart above splits UMB Financial Corporation contract activity into volume (daily flow) and open interest (cumulative inventory) per strike. The per-strike grid table beneath gives the precise numbers for the densest 30 strikes. Current put/call ratio is 0.00, call-heavy - speculative or bullish positioning dominates. Total call OI of 553 versus put OI of 80 gives a put/call OI ratio of 0.14 - structurally a slower-moving signal than the volume-based ratio.

UMBF flow vs positioning

Volume tells you what flows happened today; OI tells you what positions accumulated. Both can move in opposite directions: rising volume with falling OI means contracts are being closed (covering); rising volume with rising OI means new positions are being opened. The combination matters more than either alone for reading sentiment. The per-strike grid distinguishes the strikes attracting flow today from the strikes carrying accumulated inventory - high volume at strikes that also carry high OI typically means rolling activity (closing front-month, opening longer-dated), high volume at low-OI strikes typically means fresh directional positioning. Combined with the current positive dealer-gamma regime, large OI clusters tend to act as price magnets through expiration cycles.

Using UMBF OI/volume data alongside other surfaces

Per-strike OI is the input to dealer-gamma calculations: strikes with elevated call OI generate gamma walls that dealers must hedge into as spot approaches them. The gamma-exposure page combines this distribution with the dealers' assumed-long-gamma assumption to project hedge flow. Volume cross-checks recent positioning shifts in the chain that haven't yet shown up in cumulative OI. Pair both with the term-structure view on the volatility page to determine whether the activity is concentrated in near-dated event hedging or longer-dated structural positioning. Front-month expiration for UMBF sits at 20 days, so near-dated volume currently dominates the flow reading.
