Episode Transcript

Speaker 1 (00:00):
As always before we begin, this podcast is for informational
and educational purposes only. It is not financial advice. Always
do your own research and consult with a licensed advisor
before making any investment decisions. Welcome back to the Smarter
Money Show. I'm your host, and this is episode eighteen.
Today we're going to talk about a topic that rarely
shows up on a stock chart, but might be the

(00:22):
biggest factor in your success as an investor, your own brain.
More specifically, the behavioral traps, psychological biases, and emotional mistakes
that cost people real money year after year, decade after decade.
The truth is, you don't need to be a genius
to build wealth in the market. You don't need a
PhD or a perfect model. You need emotional control, you

(00:43):
need discipline, you need self awareness, and you need a
system that protects you from the worst version of yourself.
Because if you've ever sold a great company too early, panic,
sold at the bottom, chase a hot tip at the top,
ignored your plan, or checked your portfolio five times a day,
you're not alone. Everyone has done it, even pros. The
difference is the best investors build guardrails. The average investor doesn't.

(01:06):
So in this episode, we're going to talk about the
biggest behavioral pitfalls in investing. What they are, how they
show up in your decisions, and how to fight back
against them. You'll learn how to outsmart yourself and build
an edge that has nothing to do with stock picking
and everything to do with staying in the game. Let's
start with one of the most common ones, loss aversion.

(01:27):
This is the idea that losing money feels about twice
as bad as gaining the same amount feels good. Losing
one hundred dollars feels awful, gaining one hundred dollars feels okay.
As a result, we tend to hold on to losers
too long, hoping they'll bounce back, and sell winners too
early just to lock in the gain. That behavior alone
can drag down long term returns. The solution have a

(01:50):
pre defined cell strategy, except that some losses are necessary,
cut fast when the thesis breaks, and let winners run
longer than your ego wants. Next up is recent bias.
When something has just happened, like a market drop or
a huge rally, our brains think it will keep happening.
We overweight the recent past. After a crash, we expect

(02:11):
more crashes after a run up. We expect endless green days.
But markets are cyclical, not linear. Just because something happened
doesn't mean it will continue. The solution here is zooming out.
Look at long term charts, look at five and ten
year returns. Remind yourself of history and that it rarely
moves in straight lines. Then there's confirmation bias. You find

(02:32):
a stock you like, you read articles about why it's great,
You skip the ones that raise red flags. You follow
people on x or YouTube who agree with you, and
suddenly you're in an echo chamber. That's confirmation bias. The
cure is intentional seek disconfirming evidence. Read the bare case,
follow people who challenge your view. Ask what would make

(02:52):
me not buy this? What would force me to sell?
Another brutal one. Fomo fear of missing out. Everyone talks
about it. Nobody thinks they're doing it, but they are.
When a stock goes up fifty percent in a week
and you suddenly want to buy it, that's fomo. When
you hear about your friend's crypto win and feel the
urge to chase, that's fomo. It's emotional, not logical. The

(03:17):
solution is to have an investing playbook you stick to.
If something doesn't fit your criteria, your rules, your strategy,
you don't buy it. Period. That's discipline. Next, over confidence.
This one's dangerous because it feels like strength. You had
a few wins, you start thinking you're a stock picking genius.
You size up too big, you skip your research, You

(03:40):
make fast decisions based on vibes. Then you hit a wall.
Losses mount you start questioning everything. Overconfidence almost always leads
to risk mismanagement. The fix, stay humble, keep position sizes reasonable,
always assume you're missing something, and remember, the market doesn't
care how smart you are, only how disciplined. Let's talk

(04:00):
about anchoring. This happens when you get mentally stuck on
a specific number, like the price you paid for a stock.
Let's say you bought at one hundred dollars, it drops
to seventy five dollars. You tell yourself you'll just wait
until it gets back to one hundred dollars to sell.
That's anchoring. The market doesn't care what you paid. The
only question is would you buy this today at this price?

(04:21):
If not, why are you still holding it? Then there's
a sunk cost fallacy. This one shows up when you've
invested time, energy, or money into something and you stick
with it even when it no longer makes sense, just
because you've already invested so much. You stay in a
bad stock, or a bad strategy, or even a bad
investment to count the fix, detach, be willing to walk away.

(04:43):
The past is irrelevant. What matters is the opportunity cost
going forward. Let's not forget heard behavior. When everyone's doing something,
it feels safe, but the crowd is usually wrong. At extremes,
you fork tops and panic bottoms. The best investors often
look wrong for a while. They're early, they're quiet, they're contrarian.
You don't need to go against the crowd just to

(05:05):
be edgy, but you do need to be able to
stand alone when logic tells you to. Here's another one,
the illusion of control. We love to think we can
predict markets timetops and bottoms avoid every loss, but we can't.
No one can. The best investors don't try to control
the market. They control their behavior, their system, their risk,

(05:25):
their process. That's where your power is. And finally, let's
talk about attention bias. Whatever is loudest in the news
feels most important, but news is optimized for engagement, not accuracy.
The FED, the CPI, China Oil elections all important, sure,
but not necessarily actionable. Filter noise, focus on signal. Build

(05:47):
a filter for what actually matters to your strategy. So,
after all this, what's the takeaway? The market is complicated,
but your biggest edge isn't stock selection, it's behavior. Mastering
your own psychology is the foundation of sustainable investing. The
pros know this. They build systems that make good behavior
automatic and reduce the odds of self sabotage. You can

(06:09):
do that too. Create a rules based strategy, automate what
you can. Limit your screen time, track your emotions in
a journal, build a checklist before buying or selling, set
alerts not to act, but to observe, and above all,
zoom out. Investing is a multi decade game. You're not
trying to win this week. You're trying to win in
twenty forty five. And just to be clear, this is

(06:30):
not investment advice. This show is for educational and informational
purposes only. You should always do your own research and
speak to a licensed advisor before making investment decisions. If

the all in mistake that ruins too many Portfoli wheels.
