Weekly Recap & Briefing – Biotech, Space, Defense & AI

Macro overview, sector highlights and key catalysts for the next trading week.

Week closed: Monday, February 17 – Friday, February 20, 2026
Briefing window: Monday, February 23 – Saturday, February 28, 2026

1) Macro & Indices – February 17–20, 2026

The week closed in a slightly risk-on mode for global equities. Headlines on tariffs, inflation and Iran kept nerves on edge, but major indices still managed to grind higher.

In the U.S. the picture was roughly:

  • S&P 500 around +0.9% on the week;
  • Nasdaq Composite around +1.4%;
  • Dow Jones slightly positive, in the +0.2% area;
  • Russell 2000 small caps around +0.5%.

Outside the U.S., developed markets ended the week moderately higher while emerging markets showed a stronger rebound, consistent with a selective rotation into cyclicals and cheaper regions. In Italy, the FTSE MIB oscillated around 46,500 points, supported mainly by luxury and industrial names.

Tariffs, gold and oil

The main macro-political driver was the renewed U.S. tariff story:

  • the Supreme Court limited the use of legacy tariffs based on the IEEPA framework;
  • the White House reacted by announcing new global tariffs of 10% under a different legal basis;
  • markets read it as another source of future volatility, but not yet a full game changer for the economic cycle.

Combined with tensions around Iran, this supported:

  • gold at fresh all-time highs, above the USD 5,000/oz psychological line;
  • oil in the USD 66–67/bbl range, with clear risk of further spikes if the tariff and Middle East narrative escalates.

Macro data: cooler growth, sticky inflation

On the hard data side:

  • U.S. GDP Q4 2025 was revised down to roughly +1.4% annualized, a sharp slowdown from +4.4% in Q3, hit by the federal shutdown and softer consumption;
  • February flash PMIs pointed to slower but still positive growth: composite in the low 52s, essentially flat employment and slightly weaker orders;
  • core inflation is still hovering around 3% year-over-year, with monthly prints too warm for a relaxed Fed.

Translating this into trading terms: the macro backdrop is “ok but cooling”, inflation remains sticky and the central bank is in no hurry to cut. Indices hold up, but under the surface there is brutal sector rotation that opens opportunities and traps in high-beta themes like biotech, space, defense and AI.

2) Biotech & Healthcare – a week of extremes

In biotech the week was a textbook mix of jackpot and disaster, very useful for your RunUP narrative: clean regulatory wins and resilient commercial stories on one side, trial failures and harsh regulatory pushback on the other.

VNDA – Full approval in psychiatry

Vanda Pharmaceuticals (VNDA) reported that the FDA approved BYSANTI™ (milsaperidone) for:

  • treatment of manic or mixed episodes in bipolar I disorder in adults;
  • treatment of schizophrenia in adults.

It is classified as a New Chemical Entity (NCE), even though it is tightly linked to Fanapt given its conversion to iloperidone in the body. Just having a new approved drug in a huge psychiatry market already changes the risk perception on VNDA:

  • the story shifts from “single-product Fanapt” to a small portfolio;
  • medium-term M&A optionality appears if launch data are reasonable;
  • there is potential for a re-rating if the market starts to value BYSANTI as a USD 100–200m peak-sales asset.

In price terms the stock jumped roughly +40–50% on the news with huge volumes – a perfect real-time example of how a binary PDUFA can rewrite the risk/reward profile in a few hours.

RGNX – Gene therapy, CRL and clinical hold

Regenxbio (RGNX) received a Complete Response Letter from the FDA for RGX-121 (Hunter syndrome, MPS II). The agency requested clarification on:

  • eligibility criteria and the distinction between neuronopathic and attenuated forms of the disease;
  • comparability between the treated cohort and the external control;
  • the strength of the surrogate endpoint used as a proxy for clinical benefit.

At the same time the FDA imposed a clinical hold on RGX-121 and on another program (RGX-111 for MPS I) after a brain tumor case was reported in a treated patient. The stock sold off by roughly −20%, with sentiment damaged both on the asset and the broader platform.

It is a very clear case study for RunUP: even with an accepted BLA and a PDUFA date on the calendar, a complex surrogate-endpoint story in ultra-rare gene therapy can still get hit by a CRL and safety concerns, resetting the clock almost from scratch.

GRAIL – NHS Galleri trial and a harsh reality check

In diagnostics / multi-cancer early detection, the big shock was GRAIL:

  • the large NHS-Galleri trial (~142,000 participants) failed its primary endpoint, showing no statistically significant reduction in stage III–IV cancers versus standard of care;
  • the stock dropped roughly −45–50% in one day, erasing much of the last year’s gains;
  • the company highlights positive signals (more early-stage diagnoses, higher detection rate), but for markets and payers the core message is that the hard, unambiguous benefit is still not there.

It is a classic case of over-inflated expectations on a very sexy technology (MCED) that looks much more ambiguous once you dig into the statistics. Perfect material for a “structural risk” section in your diagnostics reports.

Telix – Radiopharma execution

On the radiopharma side, Telix Pharmaceuticals delivered strong FY 2025 numbers:

  • revenue growth around +56% year-over-year;
  • improving margins despite the company still being slightly loss-making at net level;
  • 2026 guidance pointing to roughly USD 950–970m in revenue and a credible path to profitability;
  • heavy R&D spending (USD 200–240m) to keep the radiopharma pipeline as a core growth engine.

The market rewarded the print and tone of the call with a move in the +10–15% range. It remains one of the more “commercially de-risked” stories in the radiopharma space – a useful benchmark name for quality-oriented investors.

3) Space & Defense – drones, missiles and volatile space small caps

The big picture is a global defense spending environment at record levels, with missiles, drones and advanced defense systems at the core. Space and AI sit on top of this as thematic accelerators.

Traditional defense: missiles and advanced systems

On the “classic” defense side:

  • several countries are ramping up missile, air-defense and surveillance programs;
  • U.S. plans call for a big increase in production of systems like PAC-3 over the next years;
  • large contractors remain structural beneficiaries of this “permanent war economy”.

A few specific examples:

  • Raytheon (RTX) secured a contract to develop domestic TFLN wafer capacity, a critical material for high-speed communications and sensing;
  • Elbit Systems announced new international contracts worth about USD 435m for advanced land systems and innovation programs;
  • Kratos Defense & Security reported contracts across satellite ground systems and hypersonic materials testing.

The common theme is extended revenue visibility: order books in missiles, air defense and related technologies keep growing, supporting valuations and investor appetite, especially in mid-caps with strong operating leverage.

Drones: the USD 1.1bn U.S. program

On drones, the Pentagon has kicked off a program worth over USD 1.1bn to build a large fleet of low-cost drones:

  • long-term goal: hundreds of thousands of affordable drones;
  • initial phases already point to orders around USD 150m with deliveries in roughly five months;
  • about 12 vendors are expected to be selected, later narrowing to a short list of five key winners.

This marks the transition from pure narrative to real capex. Any company that secures a meaningful role in the program effectively gains a multi-year revenue pipeline.

Space: Starlink routine, small caps on a rollercoaster

In the space segment:

  • Starlink launches continue at a high cadence, with Falcon 9 regularly putting new satellites into orbit and recovering boosters, consolidating the infrastructure lead;
  • small caps like Starfighters Space show extreme volatility – sharp rallies followed by aggressive pullbacks – on news around experimental launch concepts and industrial partnerships.

The thematic view many analysts are converging on: 2026 could be a potential breakout year for space stocks, driven by connectivity, imaging, secure communications and the early phases of “orbital compute”.

4) AI & Tech – disruption fears and “Nvidia-risk”

In AI and big tech two narratives dominated the week:

  1. Fear of AI-driven disruption
    Investors are increasingly worried that massive AI capex (data centers, chips, models) could:
    • compress margins across traditional sectors (software, services, insurers, logistics, etc.);
    • fail to deliver commensurate returns, at least in the short to medium term;
    • destroy legacy business models faster than new ones can be monetized.
  2. Selective rally in “AI enablers”
    Despite those fears, the market keeps rewarding the “picks and shovels” of the AI boom:
    • high-end chip and GPU manufacturers;
    • cloud and networking infrastructure providers;
    • AI platforms with real enterprise monetization.

Nvidia remains the main sentiment barometer: the stock benefited from expectations around GPU demand and large supply deals, ahead of next week’s earnings – a genuine reality check for the whole AI complex.

AI, regulation and the public sector

On the policy side:

  • the tension between AI safety principles and military applications is becoming more explicit, as some model developers push back against direct weaponization while defense actors seek more autonomy;
  • in antitrust and competition policy, AI assistants and agents are making it harder to define market boundaries and assess dominance, as they can quickly reshape digital markets.

In price terms the outcome is a mix of high volatility in big platforms, widening spreads between AI winners and laggards, and a market that swings between phases of euphoria and “AI fatigue”.

5) Briefing for next week – February 23–28, 2026

5.1 Macro / data

Key macro data and events on the radar:

  • U.S. Conference Board Consumer Confidence (Tuesday): crucial to gauge how households are digesting inflation, tariffs and geopolitical noise;
  • U.S. Producer Price Index (PPI, Friday): the main macro market mover of the week. A hot print after already sticky core inflation could push yields higher and delay hopes of aggressive 2026 cuts;
  • Europe & others: German CPI, Swiss GDP and Canadian GDP to assess how trade-sensitive economies are holding up;
  • China PMIs: relevant for overall sentiment on global commodity and industrial demand.

In the background, new U.S. tariff headlines and Iran tensions remain capable of triggering quick spikes in oil, defense and some fragile emerging markets.

5.2 AI / Big Tech – Nvidia earnings

The single most important event for tech/AI is Nvidia’s earnings in the middle of the week.

Two broad scenarios:

  • Positive surprise: strong numbers and solid guidance on GPU and data center demand.
    • likely strong rebound in AI enablers (chips, infrastructure, linked software);
    • potential short squeeze in names targeted by “AI bubble is over” trades.
  • Negative surprise: disappointment on demand, margins or guidance.
    • risk of another risk-off leg in AI-sensitive names;
    • rotation back into value, defensives, energy and defense.

In practice Nvidia’s print can dictate the overall mood of U.S. equities for the second half of the week.

5.3 Biotech – what to watch post VNDA, GRAIL and RGNX

There are no mega-cap PDUFAs scheduled exactly for the next five days, but the week will be all about post-event digestion:

  • VNDA: watch whether the market starts to price BYSANTI as a structural asset or treats the current spike as a temporary overshoot;
  • GRAIL: monitor any reaction from payers and regulators and deeper analysis on the NHS-Galleri data that could partially revive the MCED narrative;
  • RGNX: look for updates on FDA meetings and any roadmap to exit the clinical hold;
  • Radiopharma (Telix and peers): see if the sector can consolidate the post-earnings gains or faces profit-taking.

For RunUP Biotech, February 2026 is an excellent live teaching month: the same calendar brings approvals and strong guidance (VNDA, Telix) alongside trial failures and CRLs (GRAIL, RGNX). It is the right time to hammer home:

  • the importance of diversification in small-cap biotech;
  • the difference between commercially de-risked stories and single-endpoint bets;
  • the need to work carefully on timing and position sizing when playing pure run-up trades.

5.4 Defense / Space – focus for the coming days

In defense/space, for February 23–28 the focus is on:

  • Drones: continuation of testing and selection phases in the USD 1.1bn Pentagon program, with potential headlines on preferred vendors and first significant orders;
  • Hypersonics & missiles: possible further announcements on production ramp-ups and new development phases for attack and defense systems;
  • Space: ongoing high volatility in small caps with innovative launch and orbital concepts, and continued Starlink launches as the backbone of the space infrastructure theme.

6) Summary headline

In short: global indices closed modestly higher, with gold at record levels and oil grinding up as tariffs, inflation and Iran keep the risk premium elevated. February once again exposes the binary nature of biotech (VNDA and Telix rallying, GRAIL and RGNX under pressure), while defense and space continue to benefit from drone, missile and orbital-infrastructure contracts. All of this will converge next week into a key test: Nvidia’s earnings, the U.S. PPI print and the first tangible signals from the Pentagon’s mega drone program.
