QTR & Adam Taggart: Private Credit, Valuations, Favorite Sectors

  1. Markets look stronger on the surface than they actually are, with QE, passive flows, and options activity propping up stretched valuations and hiding pockets of fragility.
  2. Private credit is under real stress — many funds face redemptions, gated withdrawals, and questionable marks, creating the risk of a broader credit event.
  3. A more defensive stance is sensible: favor energy, utilities, and staples while selectively pursuing opportunities in nuclear, oil & gas, cybersecurity, psychedelics, and precious metals, and be cautious about overbuilt AI/software plays.

Shit Is Getting Ugly In This One Sector I'd Avoid

đź’° Finance Sectors
  1. A specific market sector is beginning to show serious problems, and the early signs suggest the situation could worsen.
  2. One company’s recent troubles are exposing cracks that hint the sector’s foundation may be weak, which could spill over and hurt the broader market.
  3. This isn’t a brand-new concern—there have been repeated warnings for years that this sector could be a hidden time bomb.

Investing Update: Bearish Data Emerges

Spilled Coffee • 28 implied HN points • 14 Feb 26
đź’° Finance Sectors
  1. Major U.S. indexes pulled back this week, led by technology, signaling a modest consolidation as investors reassess valuations and seasonal weakness approaches.
  2. On the surface breadth is strong—every S&P sector is above its 200‑day moving average and equal‑weight stocks are outperforming—but the leadership is defensive (materials, energy, utilities) while tech and communications lag, which raises questions about the rally's durability.
  3. There’s hidden stress under the indexes: an unusually large number of individual S&P stocks plunged 7%+ in a short period, a pattern that historically precedes much larger market drawdowns and increases the risk of a bigger selloff.

Investing Update: An Opportunity In Software?

Spilled Coffee • 44 implied HN points • 31 Jan 26
đź’° Finance Sectors
  1. Materials and energy are getting big inflows and clean technical breakouts, so those sectors look poised to lead the next move higher.
  2. Semiconductors are signaling market leadership and could pull big-cap tech higher, while software is deeply out of favor with record-low hedge fund exposure—so it may be a rebound opportunity but still carries AI-related downside risk.
  3. Consumer confidence and labor-market indicators are weakening even as stocks hit highs, and with February’s historical weakness after a positive January, economic pain reaching consumers could create downside risk.

Investing Update: 2025 Recap & 2026 Outlook

Spilled Coffee • 36 implied HN points • 03 Jan 26
đź’° Finance Sectors
  1. The market finished 2025 strong—S&P up about 16%, Nasdaq over 20%, and the Dow up 13%—continuing a multi‑year bull run while still seeing volatility, including a roughly 19% drawdown.
  2. Returns were concentrated and mixed across sectors and stocks. Only two mega‑cap techs beat the S&P, three sectors outperformed, and winners included communication services, semiconductors, gold miners, metals, clean energy, and silver.
  3. Active calls and stock picking paid off: a year‑end S&P forecast landed within 1% and an actively managed portfolio outperformed the S&P, showing active management can succeed but is hard to do consistently.
