Big Banks Warn of a Major Rotation: What It Means for Investors

Vlad

Published on September 10, 2025

Big banks have issued a clear warning: the market is rotating. Large technology stocks that led the last rally are slowing. At the same time, smaller companies and select sectors are gaining strength. Felix Prehn of Goat Academy explains what is changing, why it matters, and how to think about it in simple terms.

What is a rotation?

  • A “rotation” is when money moves from one group of stocks to another. Think of it like a relay race. One runner gets tired and passes the baton. Another runner picks up speed.
  • Rotations are normal. They can last months. They can shape returns more than picking single stocks.

What the data shows right now

  • Many big tech names are under pressure. Some have fallen for several weeks in a row.
  • About half of Nasdaq stocks are below their 50-day moving average. A 50-day moving average is the average price of a stock over the last 50 days. Falling below it can be a sign of weakness.
  • AI adoption is growing, but slowly, based on major bank trackers. Expectations got ahead of reality.
  • Custom chip makers are rising, which challenges a few dominant AI chip suppliers.
  • Small caps are showing strength. Small caps are smaller companies, often tracked by the Russell 2000 index.

Sectors showing momentum

  • Biotech: Biotech companies research and develop medical treatments. They can benefit when borrowing costs fall because research is expensive. When the outlook for rates improves, biotech can move.

  • Gold and gold miners: Gold can rise when investors look for safety or expect lower real interest rates. Gold miners are companies that produce gold. They often move more than gold itself, both up and down.
  • Defense: Defense firms may see steady demand due to government spending.
  • Consumer strength: Payment networks and platforms tied to daily spending can benefit when the consumer remains healthy.
  • Robotics and industrial tech: Select companies in testing, automation, and robotics may find steady growth outside headline AI hype.
  • “Boring” cash-flow stocks (like telecoms) sometimes gain favor when markets get more selective.

Why AI is not “over”

  • New technologies follow a common path. At first, excitement is high and people expect very fast change. Reality is slower at the start. This can cause disappointment.
  • Over time, adoption grows and results improve. Long-term winners can do very well. But holding the most exciting names through the slow middle period can be hard.

A simple plan in plain language

  • Be selective with AI-related stocks. Focus on quality and valuations. Valuation means the price you pay compared to earnings, cash flow, or sales. Very high valuations can be risky if growth slows.
  • Trim positions that ran too far too fast. “Trim” means selling a portion to reduce risk and lock in gains.
  • Look for sectors where money is moving now: biotech, defense, gold miners, and certain consumer and robotics names. Always check the company’s cash and balance sheet. Companies with strong cash can survive tough times.
  • Do not chase big spikes. Wait for “pullbacks.” A pullback is a short-term drop after a rise. It can offer a better entry.
  • Remember that rotations can last months. Patience helps more than trying to nail the exact day to buy or sell.

Key terms explained

  • 50-day moving average: The average closing price over the last 50 days. Above it often signals strength; below it can signal weakness.
  • Small caps: Smaller public companies. They can be more volatile but can rise fast when conditions improve.
  • Valuation: A way to judge if a stock is expensive or cheap based on its fundamentals (like earnings).
  • Pullback: A temporary price drop within an uptrend.
  • Gold miners vs. gold: Miners are companies that dig up gold. They can move more than the gold price itself.

Bottom line

The market is shifting from a narrow AI-led run to a broader mix of winners. Investors who follow where money is flowing, keep an eye on valuation, and wait for pullbacks may find better risk-reward. The goal is not perfect timing. It is to move with the rotation, protect gains in stretched areas, and stay ready to revisit AI leaders when adoption and earnings catch up.
