How to Avoid Making a Bad Decision in the Stock Market

I recently moved to Austin and have been looking for a home. As I was driving around with my wife, I was listening to one of my favorite songs from The Strokes called “Bad Decisions.” The chorus hit me hard: “Oh, makin’ bad decisions… makin’ bad decisions for you.”

That song got me thinking about all the notes I’ve been taking from negotiating real estate purchases — and how many of those hard-earned lessons lined up perfectly with my best investment decisions in the stock market. It also highlighted what often causes my worst decisions.

Why This Song Is So Good For Investors

The Strokes’ track is about the band pushing back against fans and the industry who want them to keep cloning the sound of their first hit record, "Is This It?" instead of evolving (check out the record).

The narrator hangs on every word, leaves his own ideas “in my dreams,” and still ends up doing the wrong thing because it’s for someone else.

The music video shows people ordering custom clones of the band that eventually malfunction and melt down. It’s catchy, upbeat and kind of funny, but underneath it’s a clear warning: you know better, yet you still do it for the relationship, the pressure or the thrill.

That same feeling shows up constantly when you’re buying property — or stocks. Here’s what the song and negotiating real estate has taught me, and how it ties straight into avoiding those “really, really bad decisions” in investing.

Don’t let people manipulate you.

When investing, stick to facts, logic, your goals and priorities. Give yourself time, and review your priorities away from the noise (and the computer screens). In real estate, a seller or agent drops a big new piece of information right when you’re emotional, maybe during the option period or after you’ve fallen for the place. The smart move is to step back, think slowly, talk it over with your key people and calculate on paper (or spreadsheet) before you respond.

The same thing applies to stocks. Listening to financial news and opinions in the media can be very costly to your net worth. One minute it’s all bullish hype, the next it’s panic. That conflicting noise pulls you away from your own goals and time frame. It sways you into suboptimal buys or sells. Deliberate thinking — slow, calculated and written out — keeps a lot of investors from making bad decisions “for you” (the crowd, the pundits or your own FOMO).

There are normal differences between geographical areas, industries — and between market environments.

What’s customary in Colorado negotiations is nothing like Texas. Laws differ, culture differs and sellers in one place might list way above fair market value because everyone expects heavy negotiation later, especially on repairs or credits. Views, taxes, pools or location perks can justify premiums that wouldn’t fly elsewhere.

In investing, this is like understanding that certain sectors or strategies behave differently depending on the economic backdrop. What worked in a low-interest-rate environment doesn’t translate when financing costs jump. You have to adjust your approach to the local “norms” instead of forcing a one-size-fits-all playbook.

Imperfect information and even deception is everywhere — build in a bigger margin of error than you think you need.

In real estate, you often don’t learn the full truth about a property until after closing —hidden issues, neighbor problems or seller omissions that only surface with time. That’s why you don’t have to take every deal. Leave room for surprises.

Stocks are the same. Earnings can be massaged, guidance can be optimistic and macro surprises hit when you least expect them. Give yourself a margin of safety. Walk away from the ones that feel too perfect. Not every “opportunity” is one you need to own.

External market conditions — like financing costs and credit availability — move all prices, not just the specific asset.

Interest rates and lending tightness don’t care about how nice your kitchen is or how great the company’s moat looks on paper. They lift or crush overall price levels across the board. We see this in housing markets and in broad stock valuations. You can love the property or the business, but if the external environment is working against you, the numbers just don’t work the same.

See a lot of properties (or opportunities) and really know the area before you commit — transaction costs and taxes can be brutal.

Moving, commissions, title, inspections, closing fees, opportunity cost, timing friction… getting in and out of real estate is expensive and time-consuming. It reduces both your enjoyment of the place and your actual dollar return. That’s why it pays to live in or deeply understand an area before buying, especially if you’re moving to a new state.

The same type of friction exists in investing. Trading too often eats into returns through commissions, taxes and slippage. Jumping into a hot stock or sector you don’t really understand (because everyone else is doing it) is like buying a house sight-unseen in a city you’ve never lived in. The costs add up, and the regret is real.

The Strokes song captures that addictive loop perfectly: you hang on every word from the other side (“I wanna write down every word”), you know you’re not listening to your own analysis and goals (“Never listenin’ to you”), yet you still make the bad decision “for you.” In real estate deals or in the markets, that “you” can be the seller, the media narrative, the crowd on social media, or even your own past winner that you’re emotionally attached to.

The Takeaway for me Is Simple

Whether I’m negotiating on a house or deciding on an investment, I try to:

Slow down when big new information hits.
Step away from the pressure of the media and the screens, calculate for myself and talk only to the smartest experts I know.
Respect both local differences and external conditions.
Build in margin for the stuff I can’t know yet.
Remember how expensive these decisions really are over the long run.

Crank up “Bad Decisions” by The Strokes next time you’re tempted to rush into a stock or a real estate deal. It’s a fun song with a serious reminder: don’t keep makin’ bad decisions for somebody (or something) else.

Make the clear-headed ones for you — your priorities, your time frame, and your long-term net worth.

Those are the lessons I’m carrying forward from the negotiating table and the markets. They’ve already saved me from a few meltdowns. Hope they help you avoid some too.
