NWF Advisory filed Q4 2025 with $904.9 million. The core portfolio: Berkshire Hathaway (BRK), XLK (Technology Select Sector ETF), VOO (S&P 500), and Micron (MU). A small RIA with a thoughtful barbell.
The filing
| Metric | Value |
|---|---|
| 13F AUM | $904.9M |
| Core holdings | BRK, XLK, VOO, MU |
| Filer type | Registered Investment Advisor (RIA) |
The barbell architecture
NWF's core reveals a specific portfolio philosophy:
Value anchor: BRK (Berkshire Hathaway) — Buffett's conglomerate
Tech exposure: XLK (Tech Select Sector) — broad tech via ETF
Market core: VOO (S&P 500) — passive baseline
Semiconductor: MU (Micron) — individual stock AI memory bet
Why this combination is interesting
BRK + VOO = classic conservative core. Berkshire provides value/quality and VOO provides market beta. This is the backbone of a wealth preservation portfolio.
XLK + MU = tech and semiconductor conviction. XLK gives broad tech exposure. MU adds a specific AI memory thesis on top.
The barbell: conservative foundation (BRK + VOO) with growth overlay (XLK + MU).
Micron in the core: the memory thesis at RIA scale
MU appearing in a $905M RIA's core holdings is notable:
Who else holds MU prominently
- EPF (Malaysia): MU in top holdings ($13.6B fund)
- Groupama (France): MU alongside JPM and tech
- NWF Advisory: MU in core alongside BRK/XLK/VOO
Three very different institutions (sovereign pension, French insurer, small U.S. RIA) independently holding Micron. The AI memory thesis is reaching across filer types and sizes.
Why an RIA would hold MU specifically
- HBM (High Bandwidth Memory): Critical for AI GPU clusters — structural demand growth
- Cyclical recovery: Memory sector emerging from a downturn with AI as the upswing catalyst
- Valuation: MU trades at lower multiples than NVDA while benefiting from the same AI buildout
- Complements XLK: XLK provides broad tech; MU adds targeted semiconductor conviction
Small RIA filings: hidden gems in 13F data
Small RIA filings (<$1B) are often overlooked but can be more informative than mega-filer filings:
| Dimension | Mega-filer ($500B+) | Small RIA (<$1B) |
|---|---|---|
| Position signal | Low (index weight driven) | High (every position is deliberate) |
| Concentration meaning | Often passive drift | Active conviction |
| New positions | Could be ETF/index mechanics | Research-driven entries |
| Portfolio architecture | Complex (multiple business lines) | Clear, readable thesis |
NWF's filing is readable in a way that BlackRock's 50,216-position filing is not. BRK + XLK + VOO + MU = a clear investment philosophy expressed in four names.
What NWF's filing tells you
About the RIA industry
- Small RIAs combine ETFs (XLK, VOO) with individual stocks (BRK, MU) — a hybrid approach
- Berkshire is a popular "single stock that acts like a fund" for RIA portfolios
- AI semiconductor exposure is reaching even $900M advisors
About Micron as a conviction pick
- MU appearing across sovereign pensions, insurers, AND small RIAs = broadening institutional interest
- The AI memory thesis is no longer niche — it's crossing all institutional segments
