Money Flow vs. Options Flow — Explained with $ASTS

The Concepts

Money Flow (options premium flow) aggregates all unusual options premium into crude buckets — bullish vs bearish — to answer "where is the smart money positioning?" Bullish = bought calls + sold puts; Bearish = bought puts + sold calls. Aggregate tells you direction and size. A time-series adds momentum — is bullish flow building or fading day over day.

Options Flow / UOA (Unusual Options Activity) is the same market at trade-level granularity: each sweep/block, its strike, expiration, side (bought/sold), urgency, and conviction. UOA tells you who is doing what and how confident they are. Money flow = the map; UOA = the individual footprints.

$ASTS Example — Aggregate Money Flow (8/7 – 8/21, 11 sessions)

Spot context (Latest daily close 8/21: $68.65): $25.3B market cap, beta 2.74, short float ~21.9% — a heavily-shorted, high-volatility name, so options flow here carries amplified meaning. Price is below its SMA50 ($70.5) and the Ichimoku cloud (span A ~$71-74), but above its short EMAs (8/13/21 ~$0.9- $56.5, Kijun $64), with MACD histogram positive = improving.

Window totals: Net bullish +$14.7M, bullish share 66.8% (bull/bear ratio 2.0).

Key nuance — the quality of that "66% bullish": This is mostly premium collection, not aggressive buying. Put sellers ($21.6M) + call sellers ($13.3M) own ~80% of the window's premium. Traders are selling downside — comfortable owning ASTS at $60-75 — and selling upside calls to fund it. True conviction buying (bought calls) is only $7.6M. A "67% bullish" headline would be misleading; the honest read is income/positioning around a range, with buyers stepping in at dips.

Trend shape (daily net premium, $K):

Read the shape:

• 8/10 spike (+$11.1M, 82% bullish) — one monster day (~$12.8M sweep-sold puts). That's a floor-builder — someone aggressively selling puts below the market into strength.
• 8/17 bearish day (-$1.1M, 76% bearish) — call selling dominated (blocks $973K). Overhead supply.
• 8/20 odd ( +$1.5M, 71% bullish) — calling back up.
• 8/21 (flat -$48K, ~52/48) — pause day. Both sides nearly even.

Most important trend flag: strongSweepNet (urgent call-buying minus urgent put-buying) stayed positive all 11 sessions — never flipped. The most urgent money never went net bearish once; even on the Aug 17 seller day, urgent flow was absent rather than short. That's a persistent bullish tilt beneath the chop.

Strike walls (today only):

• $75C — biggest bought wall ($277K) vs spot ~$68.75 → upside target/magnet.
• $70C — biggest sold wall ($362K) → the immediate overhead cap; dealers hedge by selling stock into strength → self-reinforcing resistance.
• Cheapest put wall at $65P/$60P sold → floor positioning.

So options traders see it as: range $64–$75, biased to re-approach $75, with $70 as the speed bump.

How to Read UOA — The Framework

Never read a single field in isolation. The direction is NOT "calls = bullish". You combine 5 elements:

1. Action + Type (the only correct way to get direction):

• Bought calls = bullish · Bought puts = bearish
• Sold calls = bearish/neutral (capping) · Sold puts = bullish (floor/income)

2. Sweep vs Block: Sweep = broken across venues for speed, paid spread — urgency. Block = negotiated desk trade — institutional, less urgent. Rank sweep above block for short-term conviction.

3. Moneyness + DTE: Far OTM = speculative/far target; short-DTE OTM = catalyst bet; ITM long DTE = hedge or stock replacement; big ITM block = probably hedging, not a bet.

4. Size vs Open Interest: Size > OI = fresh new position (high signal). Size ≪ OI = adding/rolling/closing (management, low signal).

5. Repeats: Same strike+exp trading multiple times same day = systematic accumulation — stronger than any single trade.

Real examples from today's ASTS tape (8/21):

What today's UAO says as a whole: The tape is balanced (bearish $640K vs bullish $592K) — heavy sell-side pressure put/call at $70 and off-sell at $75; buy-side leans long the $75 recovery and deep put-selling into Mar-2027. Net: chop between $64–$70, with both sides positioning for an eventual push at $75, and no collapse in the urgent bought call camp.

One reading pitfall to avoid: today's two HIGHEST-premium sold calls (Jan'28 $70C $295K and Oct $75C $108K) look large but are SOLD — they're income/cap, not directional shorts. Premium ≠ direction — every time.

Final honesty check: money flow says "constructively bullish beneath a chop (66% bull share, positive sweep net all 11 days)"; the strike walls say "$70 is the resistance fight, $75 the drawn target"; UOA says real buying conviction is thin and concentrated in short-dated $75 calls + long-dated put sales. The trend is the signal; today is a pause within it.
