Where Will Your Portfolio Be In 2031, Not Tomorrow

Follow the whole story: every piece in this series is on our AI storyline page.

The question worth a quiet weekend isn't what Monday does. It's where your money needs to be in 2031, and whether Thursday changes that. We'll get there with data: what the market did five years after its worst days, and what the biggest companies looked like five years after past selloffs.

What Does Everyone Already Know?

On Thursday, using the big index funds as stand-ins, the S&P 500 (SPY) fell 4.4% to $733.00 and the Nasdaq-100 (QQQ) 6.5%. Nvidia fell 9.3% to $181.60. Gold and long Treasuries edged up. Both funds rose on Friday, but SPY ended the week down 2.7% and QQQ down 5.0%.

It was the AI trade unwinding: the chip makers and the companies building the power and data centers behind AI fell hardest. Power is the bottleneck, opposition to new data centers is growing town by town, and the new Congress can lean on both; on Wednesday, Meta's president told a Wall Street Journal conference that the midterm results will make building data centers harder. We flagged power as the AI trade's real risk on Nov 2, in "Nvidia Stock's Real Risk Isn't China. It's Power."

The weekend question is the natural one: what happens Monday? We already looked at the short run, and after the 21 earlier days like Thursday the next week was close to a coin flip. So let's use the quiet of a Saturday to look the other way, five years out, to November 2031.

What Happened Five Years After The Worst Days?

Between the end of 2002 and Thursday, the S&P 500 fell at least 3.5% on the same day the Nasdaq Composite fell at least 5% just 21 times. Eighteen of them are more than five years old. Here's where the S&P 500 stood five years after each, grouped by episode, price only:

Eighteen of 18 higher. The median was about +100%: the index roughly doubled.

Put another way, the median works out to about 15% a year, before dividends. The worst is the one worth sitting with: September 29, 2008, when the S&P 500 fell 8.8% in a day. If you'd bought the index at that close, you'd have lived through this:

The first year felt like a mistake. The fifth year didn't, and dividends added about 16 points.

That's the whole lesson in three lines. The worst start in this data still ended up well ahead, but only for the person who was still holding.

What Did The Biggest Companies Look Like Five Years Later?

Here's the connection most people miss. Buying the index after a crash worked. But inside the index, the companies that did the compounding weren't always the biggest ones. Here's what some of the largest U.S. companies returned, with dividends, in the five years after two of the worst days:

In 2008 the giants of the day lagged and the growers multiplied. By 2020 the growers were the giants, and most of them led again.

In the fall of 2008, some of the biggest companies in America were Exxon, Walmart, Procter & Gamble, Microsoft and Johnson & Johnson. Five years after the worst day, those five averaged about 43%, well behind the index's 69%. The big winners were companies whose sales were growing fast at the time, Apple, Amazon and Google, and each of them more than doubled.

By March 2020 those growers had become the giants. Five of the biggest, Microsoft, Apple, Amazon, Alphabet and Meta, averaged about 220% over the next five years, against 154% for the index. And Exxon, which had lagged badly after 2008, more than quadrupled after 2020 from a crushed starting price. Size didn't decide the five-year result. Growth in sales and profits, plus the price you started from, mattered more.

What Do The Biggest Companies Look Like Now?

So here's the 2031 question in company terms: are the current giants still growing like compounders? Here's what the Trefis data shows for the seven largest U.S. companies at Friday's close:

Six of seven are earning a wider margin than their five-year average, and all seven grew sales by about a quarter or more in three years.

That's what compounding looks like while it's happening. Nvidia's sales are about nine times what they were three years ago. Amazon's margin is well above its five-year average. These are not the lagging giants of 2008, at least not yet.

But here's the other half, and it's why the five-year view needs a plan rather than a hunch. The same companies can fall a long way on the way to 2031. In 2022, Meta fell 74% and took until November 2023 to recover; Nvidia fell 63%; Amazon fell 52% and wasn't back until February 2024. In 2007-08, Nvidia fell 85% and didn't regain its old high until 2016. Growth compounds, but it doesn't compound in a straight line. And no table can tell you which of the current giants will look like Apple in 2013 and which like Exxon.

Does That Mean Every Five Years Is Up?

No, and we'd rather you hear the limits from us. Four of them:

The window starts after the dot-com fall. Our study window begins on December 31, 2002, so the 2000-2002 bear market, when tech stocks spent years falling, is not in this data set. We compared that era with the present in Is The Nasdaq Selloff 2000 Or 2018?

Even in this window, one big-down day was lower five years on. Widen the net to all 72 days old enough to check when the S&P fell 3% or the Nasdaq 4.5%, and 71 were higher five years later. The exception: February 27, 2007, a fall that came before the 2008 crisis, not during it. Five years later the index was slightly lower.

It's 18 days, not 18 lessons. Ten of them fell in one autumn, so this is really four episodes, each followed by a strong recovery.

It's the US market. We measured the market that came through and kept growing; not every country's market did.

So the fair reading is this: in this data, days like Thursday were not a reason to give up on a five-year plan. They weren't a guarantee either.

What Does Your Plan Need In 2031?

Here's the question that's less random than Monday's open: what does your money have to do by 2031, and does Thursday change it? A few ways to pin it down this weekend:

1. Put a number on 2031. Say you have $1 million and want $1.5 million in five years. That takes about 8.4% a year. A good plan doesn't need the median outcome to work; it should hold up if the next five years look like the worst row in our tables, or worse.

2. Own the growers broadly, not by bet. The table above says the compounders change over time, and nobody picked all of them in 2008. An index fund owned every one of them on the way up. If you hold individual giants on top of the index, size them so a 2022-size fall in any one of them doesn't break your plan.

3. Separate the five-year money from the two-year money. Anything you'll need before about 2028 doesn't belong in stocks; the person who bought on September 29, 2008 was still down a year later. Money meant for 2031 and beyond can ride out a rough first year.

4. Set one check date a year. Pick a day, say each November, to compare your mix with your target and rebalance. If you want a rule for what to buy at −10% and −20% in between, our crash-and-rally plan has one.

What this replaces: changing a five-year plan because of one day, or betting it on one company. The risk: the next five years could look like 2000-2005 rather than anything in our tables, which is exactly why the two-year money stays out of stocks. What to watch: not Monday, but whether the current giants keep growing sales and margins, whether your mix drifts outside its band, and whether your 2031 goal changes.

What's The Bigger Idea?

We call it Look beyond what's under your nose. A single day feels enormous because it's the only one you can see. Over five years it shrinks to a footnote. The numbers that mattered were whether you still owned the market at the end, and whether the companies inside it kept growing.

Thursday is the headline; 2031 is the plan. Five years after each of the 18 measurable days like Thursday since 2002, the S&P 500 was higher, median about +100% and worst +53% (price only; +69% with dividends). Inside the index, the 2008 giants lagged while the growers multiplied; the seven current giants all grew sales by about a quarter or more in three years, but fell 30% to 74% in 2022. Set your 2031 number, own the growers broadly, keep near-term money out of stocks, and check the plan once a year.
