Market Context — Tuesday May 27, 2026
Markets return from Memorial Day with the space and defense complex dominating the gap up scanner. Defense drone contractors extended a massive May rally on new NATO and U.S. Army contract announcements. The nuclear energy sector continued its momentum trade, with a major Wall Street firm naming a small modular reactor developer a potential early sector leader tied to AI data center power demand. Silicon carbide semiconductors added to their 100% May run on AI infrastructure narrative. Space infrastructure names moved together as the SpaceX IPO halo trade drew investor attention to suppliers and adjacent operators.
On the gap down side, oil majors pulled back on demand uncertainty, and a micro-cap biotech saw profit-taking after a recent move.
I have 9 tickers on my watch list this morning across the space, defense, nuclear, semiconductor, and speculative AI complex.

Full Pre-Market Watch List — May 27, 2026
Educational watch list only. Price levels shown are for context. Not entries or exits. Not financial advice. Trade your own decisions.
Sector Theme: Space, Defense, Nuclear, SiC Semis
The dominant theme on the scanner this morning is defense spending and AI power infrastructure. RDW and LUNR are moving together on space infrastructure sentiment tied to the anticipated SpaceX IPO. OKLO and WOLF are trading the AI power demand narrative. MNTS is a small float space play gapping on its own catalyst. These tend to move in sequence at open — the leader sets the tone for the rest of the complex.
MNTS — Momentus Inc. | Gap Up +66.98%
| Price | Float | ATR(14) | Volume |
| $12.34 | 5.71M | $0.93 | 16.78M |
Catalyst: Space infrastructure company with $10M in projected NASA and U.S. DoD contracts for 2026. Company completed debt-to-equity conversion on outstanding convertible notes and closed a $5M private placement. Float of 5.71M with 16.78M shares traded premarket means the stock turned over its entire float nearly 3x before the open.
What to watch: With a 5.71M float and a 67% gap, the opening range on the first 5-minute candle is the key level. A halt is possible in the first 30 minutes. ATR of $0.93 gives context for intraday range expectations. Watch for a flush of the opening candle low as a potential long setup or a break and hold above the premarket high for continuation. Educational framework only.
CODX — Co-Diagnostics Inc. | Gap Up +21.81%
| Price | Float | ATR(14) | Volume |
| $6.20 | 1.04M | $0.74 | 4.66M |
Catalyst: CODX announced completion of its assay development for Bundibugyo virus (BDBV), connected to the active Ebola outbreak in the Democratic Republic of the Congo and Uganda. Float of 1.04M is the smallest on the scanner. A $3M private placement was also recently announced.
What to watch: With a 1.04M float, this is a micro-cap biotech with extreme volatility potential. Volume of 4.66M premarket is 4.5x the entire float. Moves of 20-40% in either direction after open are possible. First 5-minute candle range and VWAP reaction are key reference points. Educational framework only.
HLIT — Harmonic Inc. | Gap Up +19.75%
| Price | Float | ATR(14) | Volume |
| $18.19 | 106.55M | $0.90 | 820,957 |
Catalyst: Harmonic announced sale of its Video business unit and raised its 2026 broadband revenue target to $475-495M. Q1 results showed a strong print. Jefferies raised price target to $15 from $10. Northland raised to $15 with an Outperform. The stock gained 19.7% last Friday on the announcement.
What to watch: With a 106M float, this is a fundamental catalyst gap rather than a float squeeze. Watch the gap fill level (prior close around $15.20) as potential support on a pullback and the premarket high as resistance for the opening drive. Educational context only.
AIIO — Robo.ai Inc. | Gap Up +19.23%
| Price | Float | ATR(14) | Volume |
| $3.10 | 13.79M | $1.31 | 6.24M |
Catalyst: Robo.ai announced its Neurovia AI unit released NeuroStream architecture and began commercial proof-of-concept certification. AIIO has been on the scanner multiple times this month, running from sub-$1 to intraday highs of $9.20 on prior sessions before fading.
What to watch: AIIO is a highly speculative micro-cap AI play. The company reported approximately $950 in total revenue with a market cap near $111M. ATR of $1.31 on a $3.10 stock is 42% daily range potential. Watch premarket high and prior day close as key reference levels. High-risk, high-volatility setup. Educational framework only.
RDW — Redwire Corporation | Gap Up +14.50%
| Price | Float | ATR(14) | Volume |
| $20.00 | 77.50M | $1.73 | 7.54M |
Catalyst: RDW extended a massive May rally (up over 90% in a single month). Multi-year NATO ally agreement for the Penguin Mk3 drone platform announced, valued in the high eight figures. A $15M follow-on U.S. Army order for Stalker UAS was secured. SpaceX IPO anticipation has driven attention to space infrastructure suppliers.
What to watch: RDW has been in a confirmed uptrend all month. At $20.00, ATR of $1.73 is the daily range context. Watch the $20 psychological level and the premarket high. On a trend day, the 9 EMA on the 5-minute chart has been a key hold level during this May run. Educational context only.
OKLO — Oklo Inc. | Gap Up +12.05%
| Price | Float | ATR(14) | Volume |
| $73.75 | 146.17M | $6.27 | 1.39M |
Catalyst: Bank of America named OKLO a potential early leader in small modular reactors, citing a binding 1.2 GWe agreement with Meta Platforms. Pipeline exceeds 14 GWe under non-binding letters. Stocktwits message volume surged 150% in 24 hours. Backed by OpenAI's Sam Altman. Zero debt.
What to watch: At $73.75 with a $6.27 ATR, OKLO moves in large dollar increments. The $70 level is key psychological support. Watch for opening range to establish before any position framework. This is the AI power infrastructure trade, not a speculative micro-cap. Educational context only.
WOLF — Wolfspeed Inc. | Gap Up +11.60%
| Price | Float | ATR(14) | Volume |
| $77.88 | 5.55M | $10.21 | 477,881 |
Catalyst: Wolfspeed is up 100% in May on the AI infrastructure and silicon carbide narrative. Citrini Research highlighted WOLF as a prime beneficiary of AI infrastructure buildout, arguing SiC fabs are strategic assets. Short covering accelerated the move from $32.50 in early May to over $77.
What to watch: WOLF has a 5.55M float at $77+, which creates outsized move potential in both directions. ATR of $10.21 means a normal day sees a $10 range. Watch the prior day close and the $80 level as near-term reference. Educational framework only.
LUNR — Intuitive Machines Inc. | Gap Up +11.29%
| Price | Float | ATR(14) | Volume |
| $42.58 | 129.26M | $4.06 | 1.29M |
Catalyst: Intuitive Machines reported record Q1 2026 revenue, record gross margin, positive Adjusted EBITDA, and a record quarter-end backlog of $1.1 billion. Craig-Hallum initiated with a Buy. Cantor Fitzgerald raised price target to $43 from $26. Moving in sympathy with RDW on SpaceX IPO halo trade.
What to watch: The $43 Cantor price target coincides with the premarket price, making that level a near-term reference. Prior Friday close was approximately $38.26. The $40 level is key psychological support. ATR of $4.06 gives intraday context. Educational only.
PL — Planet Labs PBC | Gap Up +9.41%
| Price | Float | ATR(14) | Volume |
| $48.50 | 264.79M | $3.79 | 616,005 |
Catalyst: Planet Labs is moving in sympathy with the broader space infrastructure complex. PL operates a large fleet of earth-imaging satellites with government defense and intelligence contracts. The SpaceX IPO halo trade is drawing attention to all space infrastructure operators.
What to watch: With the largest float on the list at 264.79M, PL is an institutional name. This is a sympathy move, not a direct catalyst gap. ATR of $3.79 on a $48.50 stock is a 7.8% daily range. Watch for the opening range to establish relative to the complex leader (RDW). Educational context only.
Gap Down Watch — May 27, 2026
HCWB | Gap Down -8.30%
Price: $2.6547 | Float: 1.79M | ATR: $0.54 | Volume: 426,281. Micro-cap with 1.79M float. No major news catalyst identified. Watch for reversal setup if volume dries up at open and price stabilizes near support. High-risk speculative setup. Educational only.
BP — BP PLC | Gap Down -5.18%
Price: $42.06 | Float: 71.81M | ATR: $0.96 | Volume: 1.57M. Oil major pulling back on demand uncertainty. No single catalyst identified. Watch the $41.50 level as key support on the daily. Educational context only.
