Something moved this month that hadn’t moved in years. The Dow closed above 53,000 for the first time ever. At the same time, the Philadelphia Semiconductor Index fell more than 20% from its June record, officially entering a bear market. Those two things happened in the same week, which tells you this wasn’t a broad selloff. It was a rotation.
The money didn’t just move into industrials and financials at home. It moved overseas. The Stoxx Europe 600 closed at a record high this month, its fourth straight week of gains. It’s trading at roughly a 25% valuation discount to the S&P 500. Goldman Sachs raised its Stoxx 600 forecast twice in six weeks. J.P. Morgan’s European equity strategy team says the region’s risk-reward is improving for the first time in years.
If you’ve been holding the Magnificent 7 without thinking much about it, this is worth five minutes of your attention. If you already have a plan that accounts for this, it isn’t.
Why the Chip Selloff Matters More Than the Headline Number
The semiconductor bear market didn’t happen because chips stopped mattering. It happened because the AI trade ran 105% in three months, and investors started asking whether the spending was going to pay for itself fast enough to justify it. Micron, Intel, and AMD all fell double digits in a single session at the peak of the selloff. SK Hynix slowed its production expansion plans. A Chinese AI startup called Moonshot posted a breakthrough that made investors question the assumed lead U.S. chipmakers had.
None of that erased the Magnificent 7’s earnings. Meta posted 33% revenue growth last quarter. Microsoft’s AI business is running at a $37 billion annual pace, up 123% year over year. The businesses are fine. The multiples investors were willing to pay for them are the thing that cracked.
The Case for Following the Money
One argument says this is exactly what a genuine valuation extreme is supposed to look like unwinding. U.S. mega-cap tech ran so far ahead of everything else that even a modest reversion sends real money looking for a home elsewhere. Europe, still cheap after a decade of being ignored, is where a lot of that money landed. A 25% forward P/E discount between the Stoxx 600 and the S&P 500 isn’t a rounding error. It’s the kind of gap that shows up before multi-year rotations, not during forgettable ones.
There’s also a diversification argument that has nothing to do with predicting where prices go next. If your equity exposure is concentrated in seven U.S. companies because of an employer stock plan, vested RSUs, or a 401k that hasn’t been touched since 2023, that’s a structural risk regardless of what happens to the Magnificent 7 from here. Owning something outside the U.S. isn’t a bet on Europe. It’s a hedge against being wrong about anything specific to seven companies.
The Case Against Chasing the Cash
The other argument is just as direct. Rotating money into whatever region had a good six weeks has a name, and it isn’t strategy. It’s performance chasing. The data on this is not close: investors who move money around trying to catch the next rotation consistently do worse than investors who set an allocation and leave it alone.
There’s a real wrinkle in the European story that supports this caution. Most of the Stoxx 600’s rally over the past three years has come from a rising valuation multiple, not from rising earnings. The index traded at 12.5 times forward earnings in early 2023 and now trades above 17 times. If that gap closes because European earnings catch up, the rotation is real. If it closes because the multiple falls back down, the “discount” investors are buying today gets more expensive, not less, and the rotation was a value trap dressed up as an opportunity.
We already covered the domestic half of this story two weeks ago, when the equal-weight S&P 500 started outperforming the cap-weighted index for the first time in eight months. The verdict then was to trim concentration you didn’t choose, not to chase the trend. Europe is the same test with a passport stamp on it.
The council is split on this. One side says the data on chasing performance is clear enough to override almost any story, no matter how good it sounds this month. The other side says a valuation gap this wide, sitting on top of concentration risk that’s real and measurable, isn’t the same thing as chasing a hot sector. Both sides are working from real evidence. That’s what makes this a genuine split, not a settled question with one side ignoring the facts.
The One Question That Actually Decides This Matter
Here’s the distinction that matters more than anything above it. Did you choose your current U.S. concentration on purpose, or did it happen to you?
- If you hold a total-world index fund, or you set a deliberate U.S./international split at some point and have stuck with it, this month’s headlines don’t change anything. Stay with the plan. Rebalance on your schedule, not on a news cycle.
- If you’ve never actually looked at how concentrated your portfolio is in the Magnificent 7, and it turns out to be high because of an employer stock plan or a legacy fund you inherited from a job you left years ago, that’s worth fixing. Not because Europe is guaranteed to keep winning. Because carrying risk you never agreed to is a problem on its own, independent of what happens next.
Then again, if the pull to move money into whatever’s working this month feels familiar, the data on why that instinct backfires is laid out clearly in Just Keep Buying by Nick Maggiulli. It’s the clearest case for why automated, consistent investing beats reacting to any single month’s rotation, including this one.

Frequently Asked Questions
Is the Magnificent 7 still a useful way to think about the market?
As shorthand, yes. As of this rotation, roughly a third of the S&P 500’s value still sits in those seven companies, so their moves still drag the index. Newer labels for the group have emerged, but none of them are standardized or fully investable yet, since some of the newer entrants aren’t public.
Should I sell my Magnificent 7 holdings because of the semiconductor bear market?
Not automatically. The chip selloff was a valuation reset, not an earnings collapse. What matters is whether your exposure to those seven companies is a size you chose on purpose.
How do I know if I’m overexposed to the Magnificent 7 without meaning to be?
Check any fund with “total U.S. stock,” “large cap,” or “technology” in the name for overlapping holdings. If you hold several of these funds plus individual shares from an employer plan, the overlap adds up faster than most people expect.
Is Europe actually cheap, or does the discount reflect a real problem?
Both can be true. The valuation gap is real and measurable. Whether it closes through earnings growth or through the multiple falling back down is the open question, and it’s the one to watch before treating the discount as an opportunity.
