AllianceBernstein Q1 2026 Preview: Intuitive Surgical and Netflix Rose as the Next Watchlist Names
AllianceBernstein kept Nvidia, Microsoft and Amazon on top in Q4 2025, but new exposure to Intuitive Surgical and aggressive increases in Netflix and ServiceNow made the next filing more interesting than another mega-cap recap. Here is what to watch.
ALLIANCEBERNSTEIN L.P. ended Q4 2025 with a portfolio that still started the usual way: NVDA, MSFT, AMZN, and GOOG dominated the top. But the more useful signal was in the newer and faster-growing ideas, especially ISRG, NFLX, and NOW. That makes the next filing on May 15, 2026 more interesting than a standard mega-cap leaderboard.
TL;DR
- The AI core stayed intact: NVDA and MSFT remained huge.
- Healthcare quality appeared: ISRG arrived as a major new position.
- Consumer and workflow software broadened the book: NFLX and NOW both climbed sharply.
- The portfolio did not get less growth-oriented: it got wider inside growth.
- Q1 watch: do the secondary growth winners keep gaining weight under the same mega-cap umbrella?

Why This Filing Matters
AllianceBernstein matters because it can show what a large global active manager does after the first wave of market winners has already done most of the heavy lifting. In Q4 2025, the answer was not to abandon the leaders. It was to broaden the set of winners the portfolio was willing to own.
Visible Signals In The Latest Filing
| Position | Value | Weight | Why it matters |
|---|---|---|---|
| NVDA | $18.86B | 6.50% | Nvidia remained the largest disclosed position, so the AI core stayed intact. |
| MSFT | $17.45B | 6.02% | Microsoft kept its role as a major platform anchor in the book. |
| ISRG | $2.11B | 0.73% | Intuitive Surgical was the cleanest large new add and immediately important in dollar terms. |
| NFLX | $3.42B | 1.18% | Netflix was one of the biggest share increases in the filing. |
| NOW | $1.34B | 0.46% | ServiceNow also jumped sharply, reinforcing the idea that the growth book was broadening rather than narrowing. |

What Q4 2025 Set Up
That is why ISRG, NFLX, and NOW matter so much. They turned the filing from a simple “yes, we still own the big AI names” document into a more nuanced growth-broadening story. The next filing can confirm whether that broadening continues or stalls.

Questions For Q1 2026
Does Intuitive Surgical stay large?
If ISRG remains prominent, the healthcare-quality sleeve should be treated as a durable addition.
Can Netflix keep climbing?
If NFLX keeps growing, AllianceBernstein is clearly willing to keep pressing into growth beyond the obvious mega-cap layer.
What would ServiceNow staying large mean?
If NOW remains elevated, the fund is broadening into enterprise-software execution winners rather than narrowing to just chips and cloud platforms.
Bottom Line
AllianceBernstein’s next filing matters because Q4 2025 looked like controlled broadening inside a still-dominant AI and platform core. If the same secondary winners remain important, the manager will look more intentional about building a wider growth roster for the next phase of the market.
