If you read unusual options activity for long enough, you start to notice a pattern: large, defined-structure institutional trades sometimes appear on the tape before the price move that justifies them. Sometimes a few days before. Occasionally a few weeks before.
This post walks through three of those trades from our last six months of audit data. None of them are cherry-picked from a spreadsheet of cases I selected; all three appear in the public track record and all three were flagged by our scanner the day they printed. Two are still open today, one expired in the money. We'll also be honest about how often whale-following actually pays off and what's not in this post.
1. ARM 170C 2027-03-19 — $42 to $95 in four trading days
On April 20, 2026, an institution paid $12M for ARM 170-strike calls expiring March 19, 2027 — a long-dated bullish bet at a time when ARM stock was sitting at $177.68 and looking sideways. The print hit our Unusual Flow tab the same morning, classified as a Long Call opening at entry mid $42.00.
Then this happened over the next four trading sessions, per Settled exchange tape:
| Date | ARM stock | 170C close | Return |
|---|---|---|---|
| 2026-04-20 (entry) | $177.68 | $42.00 | — |
| 2026-04-21 | $176.93 | $45.00 | +7.1% |
| 2026-04-22 | $197.50 | $59.00 | +40.5% |
| 2026-04-23 | $216.60 | $67.00 | +59.5% |
| 2026-04-24 | $234.21 | $95.00 | +126.2% |
ARM rallied 32% in four days. The 170C — already in the money at entry — picked up another $53 of intrinsic and time value, hitting +124% on Friday's close. On Monday's pullback (ARM gave back $20 to ~$214 in pre-market) the call retraced to ~$80, so the +124% peak isn't where the trade sits this morning. But the institution who positioned on 4/20 watched their $12M premium turn into ~$28M of mark-to-market profit by Friday close.
What we are NOT claiming: we are not telling you we caught a 4x. The deepest OTM strike with continuous data (K=200 exp 2027-03-19) maxed at +155% on Friday, and the K=170 was the most actively-printed strike. We're telling you the institution's positioning showed up on the tape on day 1, before the move. That's the signal — getting on the same side as a structured institutional bet, before the public reads about it.
The reasons ARM rallied that week have been written about elsewhere — strong earnings reaction, capacity guidance, AI-platform partnership news. The point isn't that anyone outside ARM's IR team had perfect knowledge. The point is that somebody sized a $12M directional bet on ARM 170 strikes the morning of 4/20, and the tape recorded it. You could have seen it the same morning.
2. NFLX 100/120 Bull Call Spread — opened 6 weeks before the breakout
On January 22, 2026, an institution executed a Bull Call Spread on NFLX — buying 50,000 contracts of the 100-strike call and selling 50,000 contracts of the 120-strike call, both expiring September 18, 2026. The two legs printed at the exact same wall-clock time and the exact same volume; our matcher reconstructed it as one institutional order with $26.0M paid for the long leg and $9.4M collected on the short leg. Net debit: $16.6M. Defined max risk.
NFLX (post-split) was trading at $84.45 the day of the entry. For this spread to print maximum profit at expiry, NFLX has to be at $120 or higher on September 18, 2026.
Here's what NFLX did:
| Period | NFLX range | What changed |
|---|---|---|
| Jan 22 (entry) | $84 | spread opened |
| Mid-Feb | $76 lows | NFLX corrected, spread underwater |
| Late Feb | $84 | sideways |
| Mar 2 | jumped to $93 | rally begins |
| Mid-March | $97 | continuation |
| Apr 14 | $108.94 high | breakout |
| Apr 21 onward | $92 | pullback in progress |
Six weeks after the spread was opened, NFLX broke above $100 and stayed there through April. As of last Friday, the spread is marked at +$3.57M / +10.1% on gross premium — but the more honest framing is +21.5% on the net $16.6M capital deployed, and theoretical max payoff is $99M – $16.6M debit = $82.4M (+496%) if NFLX is anywhere above $120 by September 18.
Honesty note: the same institution had also opened two larger short-call positions on NFLX on the same day (a 122K SELL of the 100C and a 121K SELL of the 120C — together a Short Call Strangle for $46M of credit). They closed those Short Call positions on February 25 — before the rally — at a small profit. So the institution itself didn't ride the full move on those legs. The Bull Call Spread is the one that's still alive and capturing the rally.
What this case demonstrates: institutional positioning can be visible weeks before the price move that justifies it. The spread structure also tells you something the long-call-only flow doesn't — the institution sized its risk to a defined corridor and was willing to give up upside above $120 to lower its breakeven.
3. INTC 40-strike call buy — $57M whale before INTC doubled
The biggest pop of any UOA print we've audited in the last six months was on Intel.
On March 16, 2026, with INTC trading at $47.53, an institution bought 50,000 contracts of the INTC June-18 40-strike call, paying $11.30 per contract — about $57 million in premium. The strike was barely in the money. Sized 50× the contract's typical daily volume.
By April 24, INTC had closed at $92.15. The 40-strike call closed at $45.00. The latest mark on April 28 is $44.64 — still up almost 4× from entry.
| Date | INTC stock | 40C close |
|---|---|---|
| 2026-03-16 (entry) | $47.53 | $11.30 |
| 2026-04-13 | $76.40 | ~$28.40 |
| 2026-04-24 (peak) | $92.15 | $45.00 |
| 2026-04-29 | $94.75 | $44.64 |
The stock roughly doubled. The option roughly quadrupled. Both peaked April 24, six trading weeks after the print. This is the kind of trade that makes the highlight reel — high-conviction, well-sized, ITM directional bet on a name that subsequently moved.
For the full story (the strike, the sizing logic, the 99% stock pop, why ITM long calls behave the way they do on big underlying moves), read the dedicated INTC flashback.
When this doesn't work
It would be dishonest to write a "whales knew first" post without telling you the failure rate. The aggregate of our last six months of closed UOA trades:
- Win rate is closer to a coin flip than to an edge on raw, unfiltered UOA flow.
- The median trade return is negative — most institutional prints don't print like ARM, INTC, or NVDA did.
- A meaningful share of trades give up more than half their premium between entry and exit.
- The aggregate dollar P&L over the window is negative once you include all the trades, not just the winners.
Average closed unusual options trade is a loser, by both win rate and dollar return. The institutions printing those trades are not always right, and they don't always hold to expiry. Some of them get crushed by the kind of move ARM had in the opposite direction. Others are hedges or unwinds that look like fresh directional bets but aren't.
What this means in practice:
- Don't blindly mirror. Use unusual flow as one signal among several. The trades that work tend to share characteristics — defined structure (spreads beat naked calls), enough DTE to survive a chop, and confirming flow on related strikes — but no rule guarantees a winner.
- Size to the loss case. If you're following a long-call entry, assume it will print -100% unless you have a thesis for closing it earlier. The institution is paying a single premium they can afford; you're paying a single premium that has to fit your account.
- Watch the structure, not the headline. The same ticker can have bullish and bearish institutional flow on the same day (NFLX 1/22 had both a Bull Call Spread and a Short Call Strangle within hours of each other). Reading the structure tells you what the smart money actually meant.
What "moved before the news" actually means
There's no claim here that institutions have illegal information. The detection runs on prints that hit the public options tape during normal trading hours; the trades you see in the daily digest are from the previous session. What unusual options flow gives you is positioning, not future facts. Institutions price news ahead, sometimes correctly. Their trades show up on the tape before the move because that's when they put on the position.
You're not seeing what's about to happen. You're seeing what someone with a much bigger checkbook than yours thinks is about to happen.
Verify any of these trades
Every claim in this post is anchored to one or more rows in our public uoa_trades dataset. The ARM 170C trade is row date_traded='2026-04-20', symbol='ARM', strike=170, expiration='2027-03-19'. The NFLX bull spread is execution_group='NFLX_2026-09-18_2026-01-22_*'. The VRT spread is the implicit Bull Call Spread on 2025-12-11.
You can browse all of them at the public track record page — including the losers we didn't write about.
