SharkWater Trading  •  Data Centers • Insider Filings Nebius Director Files to Sell 500,000 Shares, $121 Million, Under a May Plan October 6, 2026 Bottom Line Up Front Nebius Group (Nasdaq: NBIS) filed a Form 144 on October 6, 2026 for 500,000 shares with an aggregate market value of $121,405,000, about 0.21 percent of 238,400,165 shares outstanding. The seller is listed as Ophir Nave, Director and Officer, under a plan adopted May 22, 2026. The filing reports no sales in the prior three months. The executed price and post-sale holdings are not yet public because the matching Form 4 had not appeared in the EDGAR feed at the time of writing. What Was Filed A Form 144 is notice of intent to sell restricted or control securities. It is not the sale itself. The filing gives an approximate sale date of October 5, 2026, which is the day before it was filed, so the trade may already be done. The Form 4 that reports actual execution is due within two business days of the trade. Form 144 field As filed Seller (per filing) Ophir Nave, listed as Director and Officer Shares to be sold 500,000 Aggregate market value $121,405,000 (implies about $242.81 per share) Approximate sale date 10/05/2026 Plan adoption date 05/22/2026 Shares outstanding 238,400,165 (about 0.21% sold) Sold in prior 3 months None reported Source: Nebius Group N.V. Form 144, SEC EDGAR, filed October 6, 2026 (accession 0001950047-26-010048). Why the Plan Date Matters The plan was adopted May 22, 2026, more than four months before the filing. A plan adopted that far back means the sale instructions were set well before this filing. The filing does not say the plan is a Rule 10b5-1 plan beyond the adoption date, and this desk has not read the plan terms. Whether the 500,000 is a single tranche or one of several is not stated. Context from the same feed: three Form 4s were filed October 5 for sales dated October 1. The two this desk read, from the Chief Infrastructure Officer (29,090 shares at $234.16) and the Chief Technology Officer (14,546 shares at $234.16), were automatic sales to cover tax withholding on vested restricted share units. Those are routine. The director filing is a different animal at roughly 11 times the combined size. A harbor pilot unloading ballast before the swell hits and a crew trimming sail for the weather are doing different things with the same rope. A tax-cover sale is trimming sail. A planned half-million-share sale is a bigger move, and the plan date is the logbook entry that tells you when the captain decided. The Bull Case Scheduled, not reactive. The plan was adopted May 22, 2026, so the sale was set months ahead of this filing. Small against the float. 500,000 shares is about 0.21 percent of shares outstanding, which is modest supply for a name this size. No prior selling. The filing reports nothing sold in the last three months, so this is not a continuing drip. The Bear Case Dollar size is real. $121.4 million is not a tax-cover sale. It is a deliberate liquidation by a person listed as both director and officer. Part of a cluster. A separate Nebius Form 144 was filed September 30 (contents not read by this desk), and three Form 4s followed October 5. Insider paper is stacking up. Unknowns remain. No executed price, no post-sale holdings, no plan terms. The tranche count is not stated. The SharkWater Take This is a filing worth noting and not yet a reason to act. A plan set in May takes the sting out of the timing argument, and 0.21 percent of shares outstanding will not move the float. What I want is the Form 4: the real price, and what the holder still owns afterward. Until that prints, I am treating this as a data point, not a signal. If the post-sale stake is small, the read gets worse. If it is a minor trim, this was noise. Tight lines, SharkWater Educational and informational purposes only. Not personalized investment advice.

SharkWater Trading  •  Space Desk • Rocket Lab Rocket Lab Officer Files to Sell the Same 140,157-Share Block He Sold a Month Ago October 5, 2026 Bottom Line Up Front Rocket Lab (Nasdaq: RKLB) officer Adam C Spice filed a Form 144 on October 1, 2026 to sell 140,157 shares, valued at $9,766,140 on the form, through Morgan Stanley. The block is identical in size to his September 2 sale of 140,157 shares ($8,777,725). Both sit under a Rule 10b5-1 plan he adopted on June 3, 2026. The proposed block is about 0.023 percent of 598,350,482 shares outstanding. This is a scheduled sale, not a signal. The useful number is the implied price: roughly $69.68 a share versus roughly $62.62 a month earlier. What the Form Says The filer lists his relationship to the issuer as "Officer." The form does not give a title, so I am not assigning one. Shares to be sold: 140,157. Approximate sale date: October 1, 2026. The plan adoption date, June 3, 2026, matters because a plan adopted months ahead removes the "he knows something" read. Date Shares Value Aug 17 15,718 $1,291,812 Aug 18 30,908 $2,484,248 Aug 24 9,677 $673,790 Sep 2 140,157 $8,777,725 Oct 1 (proposed) 140,157 $9,766,140 Source: Form 144 filed October 1, 2026 by Adam C Spice (SEC EDGAR, primary document). Oct 1 value is the filer's estimated aggregate market value, not an executed price. Past three months of sales as listed on the form. Divide value by shares and the Oct 1 block prices at about $69.68. The Sep 2 block works out to about $62.62. That is an increase of roughly 11 percent between the two sales. The prices are my arithmetic on the filing's dollar values, not quoted trades. A 10b5-1 plan is a tide clock. The water comes in when the clock says, not when the captain feels like it. What I Could Not Check I could not retrieve the matching Form 4 for the October 1 sale, so the executed price and the post-sale holdings are not verified. I also did not pull Rocket Lab's own newsroom for October. Nothing here says the sale happened at the filed value. The Bull Case Pre-committed selling. The plan dates to June 3, 2026. The sale schedule was set months before the October 1 filing. Small against the float. 140,157 shares is about 0.023 percent of shares outstanding. It does not move the tape. Still higher. The implied price rose about 11 percent between the two sales, so the plan sold into strength, not weakness. The Bear Case It is recurring. Four sales since August 17 total roughly $13.2 million in proceeds on the form. Steady supply is still supply. Cadence is accelerating. Three small August sales gave way to two identical 140,157-share blocks, a month apart. Price is the tell. An officer selling at about $69.68 is not pricing in a collapse. That cuts both ways for anyone hoping for a discount. The SharkWater Take I pass on this as a trade. A scheduled sale under a plan adopted in June tells me when the officer needs liquidity, not what the company will do. The thing I would watch is the next 140,157-share block in early November. If the size changes or the plan gets amended, that is information. Until then this is housekeeping with a dollar sign on it. Tight lines. SharkWater Educational and informational purposes only.

SharkWater Trading  •  Space Desk • Planet Labs Planet Labs Jumped 8.4 Percent on a Launch and a Press Release That Is Eight Days Old October 4, 2026 Bottom Line Up Front Planet Labs (NYSE: PL) closed Friday, October 2, 2026 at $17.50, up 8.43 percent, on 14.85 million shares, versus 7.94 million the session before (StockAnalysis, aggregator, NOT VERIFIED). The likely trigger is a Falcon 9 rideshare that put 20 satellites in orbit, including one built with Google for Project Suncatcher (Motley Fool, October 2, 2026). One outlet credits the Amazon.ia platform instead. Planet's own newsroom dates Amazon.ia to September 24, so that story was eight days old when the stock moved. I found no Planet press release for the launch itself. This is a space-group tailwind with a thin company-specific catalyst. I am not chasing it. What Moved PL gained 8.43 percent Friday on nearly double Thursday's volume. Motley Fool had it up 7.8 percent at 11:40 a.m. ET, so the stock held its gains into the close. Session Close (change) Volume (shares) Sep 30 n/a 10,179,035 Oct 1 n/a 7,944,565 Oct 2 $17.50 (+8.43%) 14,845,020 Source: StockAnalysis price history, an aggregator. NOT VERIFIED against an exchange source. Read October 4, 2026. Sep 30 and Oct 1 closes were not retrieved. The 20-day average volume was not retrieved, so the "twice average" screen is not tested. The price move alone (over 5 percent) trips the flag. Two Explanations, One Is Stale Motley Fool (October 2, 2026) says the pop followed the launch of 20 satellites on a SpaceX Transporter mission: 18 SuperDove imagers, one Tanager-2 hyperspectral satellite, and one Project Suncatcher satellite carrying Google Tensor Processing Units to test AI compute in orbit. The piece frames Suncatcher as the potential new revenue stream and says S&P Global Market Intelligence analysts do not expect profitability until 2029. StocksToTrade (October 2, 2026) leads with something else. It says shares "jumped 7.2 percent after the Amazon.ia launch," a biodiversity AI platform backed by over $14 million from the Bezos Earth Fund, and adds a fleet count of 718 satellites and a 5,700 square meter Berlin factory with capacity for 60 Pelican satellites a year. Check that against Planet's own news page. Amazon.ia is dated September 24, 2026 and the German manufacturing item is dated September 21, 2026. Neither was fresh Friday. The launch was. A stock that bites on week-old bait is usually reacting to the tide, not the bait. Planet's newsroom page, as read October 4, 2026, did not yet list a launch announcement. Either the release is posted elsewhere (a wire service) or it has not run. I could not confirm which. I also did not verify the Suncatcher details against Alphabet or Planet. Treat the satellite counts as secondary. The Bull Case Real hardware in orbit. Twenty satellites launched Friday, including a Google-linked AI compute test. That is a physical event, not a headline. Participation. Volume nearly doubled from Thursday, and the stock held most of its intraday gain. A friendly tape. VIX read 15.31, down 6.59 percent on the day (Cboe, October 2, 2026). Risk appetite is not the constraint. The Bear Case The cause is secondhand. Two outlets, two different explanations, one of which rests on a September 24 announcement. Suncatcher is a test, not revenue. The story that makes the launch exciting has no sourced dollar figure attached. Profitability is years out. The analyst view Motley Fool cites puts it at 2029. That is a long time to fund at this valuation. The SharkWater Take I stay on the sideline. Launches are scheduled events, and a stock that rallies on one that was on the calendar is paying for something the market already knew. Show me the Suncatcher contract value, or an 8-K, and I reopen this. Until then the move is group momentum with a satellite photo attached. I can tell you what the stock did. I cannot tell you the 8.4 percent was earned by anything new. Tight lines. SharkWater Educational and informational purposes only. Not personalized investment advice. Price and volume figures come from an aggregator and are NOT VERIFIED. Cause attribution comes from secondary outlets.

SharkWater Trading  •  Semiconductor Desk • Wolfspeed Wolfspeed Ran Again. Volume Tripled, and the Reason Is Still Secondhand. October 3, 2026 Bottom Line Up Front Wolfspeed (NYSE: WOLF) closed Friday, October 2, 2026 at $35.00, up 12.29 percent on 6.81 million shares, about 3.0 times its 20-day average of 2.27 million (the average is dated October 1 and may include that day). Two sessions have now added 24.4 percent from the September 30 close of $28.13 (StockAnalysis, aggregator, NOT VERIFIED). I still found no 8-K and no named customer. Secondary outlets credit a semiconductor rotation and a 200 mm substrate release. The rotation story has a hole in it: Micron fell 2.05 percent the same day. I am still not chasing this. What Moved WOLF opened Friday at $32.35, a gap of 3.8 percent over Thursday's $31.17 close. It ran to $36.49, dropped to $31.62, and finished at $35.00, $1.49 under the high. Friday's volume was nearly double Thursday's 3.11 million. Session Close Change Volume (shares) Sep 29 $28.13 +1.99% 2.04M Sep 30 $28.13 flat 4.08M Oct 1 $31.17 +10.81% 3.11M Oct 2 (open $32.35, high $36.49, low $31.62) $35.00 +12.29% 6.81M Source: StockAnalysis price history, an aggregator. NOT VERIFIED against an exchange or issuer source. Read October 3, 2026. One data conflict. A Korean aggregator (JKN) reports a Friday close of $36.25, up 16.30 percent. StockAnalysis shows $35.00 and 12.29 percent. I cannot reconcile the two from a primary source, so I use the lower print and flag the gap. A US outlet (Kalkine) published an intraday read of $34.78, up 11.58 percent, which fits StockAnalysis better. The Explanation Going Around Kalkine, dated October 2, 2026, names two causes. The first is investors rotating into semiconductors after Micron reported blockbuster results. The second is the company's premium 200 mm silicon carbide substrate release. Neither is a filing. JKN adds "relative value" buying after a long slide. Check the rotation claim against the tape. Micron moved +3.03 percent on October 1, the session after its results. On October 2 it fell 2.05 percent to $1,074.89. NVIDIA rose 1.34 percent and Broadcom rose 3.35 percent. WOLF rose 12.29 percent. A Micron-led rotation does not explain a Friday move in a stock that made its biggest gain while Micron went the other way. Substrate and silicon carbide are a different supply chain from memory. When one boat in the fleet is hauling nets and the rest are drifting, the tide is not the reason. Somebody found fish. The same Kalkine piece carries the cold water. It puts the stock 57 percent below a 52-week high of $80.82, above the analyst targets it cites of $25 to $27.50, with revenue down 24 percent year over year last quarter. Those are third-party figures, not mine, and I have not checked them against the 10-Q. The Bull Case Momentum with participation. Two up sessions, the second on about three times average volume. A sector that is working. NVIDIA and Broadcom both rose Friday, and VIX read 15.31, down 6.59 percent on the day (Cboe, October 2, 2026). Risk appetite is not the constraint. A concrete product claim. An orderable 200 mm premium substrate with dedicated capacity, per the company's own release. The Bear Case Still no primary catalyst. No filing, customer or order size found, and EDGAR was not directly queryable in this run. A 24 percent two-day run. The stock now sits above the sell-side targets cited by the outlet that explained the move. The cause does not fit the tape. The rotation story depends on Micron, and Micron fell on the day WOLF made its largest gain. The SharkWater Take I stay out. A stock that jumps 24 percent in two sessions on a story the tape contradicts has not earned a position from me. If a filing or a named customer surfaces, I reopen the file. If the stock gives back the gap with no news, that tells me the buyers had no story either. I can say what the chart did. I cannot tell you why, and neither can anyone quoting a rotation that Micron sat out. Tight lines. SharkWater Educational and informational purposes only. Not personalized investment advice.

SharkWater Trading  •  Semiconductor Desk • Tape Without a Story Wolfspeed Jumped 10.8 Percent. I Cannot Find the Reason. October 2, 2026 Bottom Line Up Front Wolfspeed (NYSE: WOLF) closed October 1, 2026 at $31.17, up 10.81 percent from $28.13, on 3.11 million shares against a 20-day average of 2.27 million, about 1.4 times (StockAnalysis, aggregator, NOT VERIFIED). I found no 8-K, no earnings event and no dated company release inside that window. The only recent company item I could read is a product release on its own site, dated September 27, 2026 as the page shows it. A move this size with no sourced cause is a tape signal, not a thesis. I am not chasing it. What Moved WOLF opened October 1 at $28.72, a gap of about 2.1 percent over the prior close. It ran to a high of $31.39, touched a low of $28.03, and closed at $31.17, within 22 cents of the high. After-hours showed $31.31. The same page listed no news dated October 1 or 2. Session Close Change Volume (shares) Sep 29 $28.13 +1.99% 2.04M Sep 30 $28.13 not shown 4.08M Oct 1 (open $28.72, high $31.39, low $28.03) $31.17 +10.81% 3.11M Source: StockAnalysis price history, an aggregator. NOT VERIFIED against an exchange or issuer source. Read on October 2, 2026. Volume ran ahead of price. September 30 traded 4.08 million shares, about 1.8 times the same average, while the stock closed flat at $28.13. The change cell for that day was blank on the source page. Someone was active a session early. I cannot say who. The Only Company Item Wolfspeed's own site carries a release headlined "Wolfspeed Expands 200 mm Silicon Carbide Portfolio with New Premium Power Substrates." The page shows a September 27, 2026 date, which is a Sunday, so I treat the date as unconfirmed. The company says the substrate has fewer than 0.01 micropipes per square centimeter, is orderable immediately, and comes with dedicated capacity. Those are the company's own claims. The release names no customer, no order size and no revenue figure. A product spec sheet moved a stock 10.8 percent four sessions after it was posted? I do not buy that as the whole story. It may be part of it. Baitfish breaking the surface tell you something is feeding below. They do not tell you what, and they do not tell you if it is still there. The Bull Case Strength held into the close. The stock finished within 22 cents of its high and showed a higher print after hours. Volume confirmed. Volume exceeded the average on the day and on the session before it. A tangible product. An orderable 200 mm premium substrate with dedicated capacity is a concrete commercial step, as the company describes it. The Bear Case No sourced catalyst. I found no filing, earnings event or named customer behind the move. Volume was modest. About 1.4 times average is not a capitulation or a squeeze signature, and the average may already include October 1. Unexplained gaps retrace. A move with no story gives buyers nothing to hold onto when the next seller shows up. The SharkWater Take I stay out. I trade stories I can source, and this one has a chart and a mystery. If a primary filing or a named customer shows up, I reopen the file. Until then the question is not whether WOLF can run further. It is who was buying on September 30 and why they were early. I cannot answer that from public pages, and neither can the aggregators that will explain it to you by tonight. Tight lines. SharkWater Educational and informational purposes only. Not personalized investment advice. Price and volume figures come from an aggregator and are NOT VERIFIED. The company release was read through an automated page reader.
