SNDK Options Flow Turns Bullish Despite 7% Stock Drop

The Flow Picture

SNDK dropped nearly 7% Thursday after weak forward guidance overshadowed a $39.25 EPS beat. The stock closed around $1,258. But while price was falling, institutional options flow was doing something else entirely: $86.2M in net bullish premium hit the tape.

That's not a small number for a name with this much recent volatility. SNDK swung from $2,350 to under $1,000 over the past month before bouncing back above $1,250. The fact that size buyers are stepping in with calls, not puts, after a guidance miss tells you the flow isn't chasing today's move. It's positioning for the next one.

Where the Size Landed

The largest single alert was $0.68M in CALL $1300 exp 2026-10-16, flagged under the RepeatedHitsAscendingFill rule. That rule triggers when a position gets built through multiple fills at progressively higher prices, which usually means someone is accumulating rather than scaling out. October expiry gives this trade plenty of runway to work, spanning the next earnings cycle and any mean reversion from the current selloff.

Closer to the money, CALL $1250 exp 2026-08-07 saw $0.08M and CALL $1290 exp 2026-08-07 drew $0.11M. These are short-dated and close to the current spot price, which puts them in gamma-heavy territory. If SNDK gaps higher tomorrow, these contracts will move fast. The structure here looks like a combination of near term lottery tickets and longer dated directional bets.

The Put Side Isn't Absent

Not all the flow was bullish. PUT $1190 exp 2026-08-21 printed $0.21M under the same RepeatedHitsAscendingFill pattern. That's a strike roughly 5% below current levels with two weeks to work. It could be outright bearish, but given the call-heavy net premium, the more likely read is that this is a hedge leg. Someone long calls may be buying downside insurance to define risk.

There was also some PUT activity at the 1275, 1270, and 1250 strikes expiring 2026-08-07. The fills on those were small, ranging from $0.05M to $0.08M. Some were DescendingFill patterns, which can indicate profit taking or rolling out of existing positions. Hard to call these directional with conviction.

Context: Why SNDK Is Moving Like This

The stock has been a volatility vehicle for weeks. After reporting Q4 revenue of $8.97B and crushing EPS estimates, SNDK still sold off because fiscal Q1 guidance came in at $10.3B to $10.8B versus street expectations of $11.16B. Gross margin hit a record 84.6%, but that wasn't enough to hold the tape.

This is textbook momentum unwind. SNDK ran from $1,000 to nearly $1,350 in days, then gave back a chunk on the guidance miss. The net bullish flow suggests that at least some institutional players view this as a buyable dip rather than the start of a deeper unwind. Whether they're right depends on whether the $1,200 level holds as a floor.

Dealer Positioning and What to Watch

With significant call accumulation at the 1250 and 1300 strikes, dealers are likely short gamma in that zone. If SNDK rallies back toward 1300, dealers will need to buy stock to hedge, which could accelerate the move. The flip side is also true: if the stock drifts lower, dealers unwind those hedges by selling, adding pressure on the way down.

The 1300 strike on October expiry is the level to monitor. That's where the largest size landed, and it's roughly 3% above current price. A sustained move through 1300 would likely trigger a gamma squeeze dynamic. Conversely, if SNDK breaks below 1200, the put activity at 1190 becomes relevant, and the bullish thesis gets challenged.

Tactical Takeaway

Net premium is bullish, but the setup is not clean. You have a stock that just missed guidance, is trading at rich multiples around 38x earnings, and has been whipping 10% in single sessions. The October 1300 calls suggest someone is betting on a recovery, but they're giving themselves time.

If you're watching this name, the level to respect is 1200 on the downside. A close below that on expanding volume would invalidate the bullish flow thesis. On the upside, watch for sustained action above 1300, which is where dealer hedging could amplify any rally. The Friday 0DTE at 1250 and 1290 will tell you how aggressive near term sentiment is when the market opens.
