Codie Sanchez Says You're Getting Played by Index Funds — She's Not Wrong

I just watched Codie Sanchez's video "If I Started Investing Today, This is What I'd Do" and it confirmed a lot of things I've believed for years but rarely hear said out loud in the mainstream investing conversation.

Fair warning: if you're heavily into the "just put everything in index funds and don't think about it" camp, this might be uncomfortable. But I think it's worth sitting with.

The Diversification Illusion

Sanchez opens with something that stopped me in my tracks. Ten stocks control 28 percent of the entire S&P 500. Ten companies out of 500. That's not broad diversification. That's a concentrated bet on a small group of large-cap tech companies dressed up in diversification language.

Most people buying index funds think they're spreading their risk across the whole market. What they're actually doing, in large part, is buying a highly concentrated position in the companies that are already the biggest. By definition, that means you're betting on the companies that have already run.

She uses Kodak as the example in the video. In the 1990s, Kodak had 90 percent of the film market. Printing money. They filed for bankruptcy in 2012. Digital disruption didn't just hurt them — it wiped out the entire business model. And not one of those dominant companies from that era's top 10 is in today's top 10.

The lesson isn't that index funds are bad. The lesson is that "diversification" in the S&P 500 is a story we tell ourselves. The actual exposure is narrower than the marketing suggests.

The IPO Problem Nobody Talks About

Here's the part of the video I thought was genuinely underreported. In the mid-1990s, there were about 8,000 public companies. Today it's roughly half that. The building that used to be the Pacific Stock Exchange is now a gym.

Companies are staying private longer — an average of 12 years before going public now, versus 8 years before. And by the time they do IPO, they're often already valued at 10 to 50 billion dollars.

Sanchez's point is direct: by the time you can buy shares as a regular investor, you're not early. You're the exit liquidity. The VCs, the private equity firms, the insiders — they already captured the 10x, the 50x, the 100x run. You're getting what's left.

That's a hard thing to hear if you've been told that buying the index means participating in the growth of American business. In some ways you are. In the ways that matter most — the compounding early growth — you're largely not.

I've Sat in a Room Where Everyone Thinks Like This

I attended the Conscious Investor Growth Summit in Coeur d'Alene a while back. The room was full of multimillionaires, and the thing that struck me wasn't their tactics. It was their mindset. Almost none of them talked about index funds as a primary wealth vehicle. They talked about ownership. Businesses. Assets that generate cash flow and that they actually understood.

What Codie is describing in this video is the way those people think about money. Not as a passive participant in someone else's machine, but as an owner.

I've always been wired this way. I own businesses. I don't rely on a paycheck. The idea of parking money in a product I don't control and waiting for someone else's decisions to make me rich has never sat right with me. And hearing Codie lay out the structural reasons for why that instinct is sound — not just a personality quirk — was genuinely satisfying.

She says in the video that her thesis is to think like an owner, not a passive investor. The opportunity she sees is in private businesses, Main Street companies, direct ownership — not just buying tickers.

What "Thinking Like an Owner" Actually Means

Sanchez doesn't just critique the status quo — she explains the mindset shift. And it comes back to the same core idea: get closer to the asset.

When you own a business or a cash-flowing property or a stake in something private, you have information, influence, and upside that a passive index investor doesn't. You understand what you own. You can affect the outcome. You're not just along for the ride.

That doesn't mean everyone should go buy a laundromat tomorrow. But it does mean that the default advice — "max your 401k, buy the index, don't think about it" — is advice built for a different era. An era when the stock market reflected broad economic participation, when companies went public earlier and smaller, when the real growth was still available to retail investors.

That era is largely over.

The Bottom Line

What Codie Sanchez is saying in this video isn't anti-investing. It's pro-ownership. She's not telling you to stuff cash under a mattress — she's telling you to think harder about what you're actually buying and whether the story being sold to you matches the reality of the structure.

My consistent message has been: learn money mindset before you learn any specific money tactic. Because the tactics that work change. The mindset — thinking like an owner, being intentional about where your capital goes, understanding the actual risk instead of the marketed version of it — that stays relevant.

Watch this video. Then ask yourself what you actually own versus what you've been told you own. There's often a gap.
