Most investors think they know the answer. Is it really possible to Beat the Market over time?
If you could read tomorrow’s newspaper today, surely you could make a fortune investing.
You’d know whether inflation surprised to the upside, whether the Federal Reserve changed interest rates, whether unemployment rose or fell, and whether geopolitical events rattled the markets. You could simply trade before everyone else, and potentially beat the market.
It sounds like the ultimate investing advantage.
The problem is…
It isn’t.
A fascinating experiment demonstrates why, and it reveals one of the most important lessons in behavioral finance: investment success depends far less on information than most investors believe.

The Crystal Ball Experiment
A few years ago, Elm Wealth conducted what they called the Crystal Ball Study, later highlighted by The Wall Street Journal.
The premise was brilliantly simple.
Participants were given tomorrow’s newspaper headlines today.
Not predictions.
Not forecasts.
The actual headlines that would appear the following day.
Participants could then invest using the S&P 500 and long-term Treasury bonds. They could buy, sell, short the market, or even use leverage.
In other words, they were handed something investors have dreamed about forever:
Tomorrow’s news before everyone else.
If information alone created investing success, this should have been a tremendous advantage.
Instead, it exposed something far more interesting.
Knowing the Future Wasn’t Enough
The initial experiment involved approximately 120 participants.
The average result?
Essentially break even.
Even more surprising, one out of every six participants lost everything.
The researchers then opened the experiment to the public.
More than 60,000 investors participated.
Collectively, they performed even worse.
Read that again.
Thousands of people knew tomorrow’s headlines…and still did worse than break even.
Markets Don’t Respond to Headlines Alone
The results surprise many investors because they assume markets simply react to news.
Reality is much more complicated.
Markets respond to how millions of investors interpret that news.
A headline that appears overwhelmingly positive may already be fully expected by investors.
A disappointing economic report may actually send markets higher because investors feared something even worse.
Corporate earnings can beat expectations, yet stocks decline because investors expected even bigger surprises.
The market isn’t reacting to events alone.
It’s reacting to expectations, valuations, positioning, sentiment, and the psychology of millions of investors trying to anticipate everyone else’s reactions.
Knowing tomorrow’s headline doesn’t tell you how the market will interpret it.
And that difference is enormous.
Confidence Can Become Expensive
One aspect of the experiment deserves even more attention.
Many participants didn’t simply make incorrect decisions.
They made oversized incorrect decisions.
Behavioral finance has shown repeatedly that confidence often grows faster than accuracy. When investors become convinced they’re right, they frequently increase the size of their bets.
That combination can be devastating.
Being wrong is part of investing.
Being wrong while taking an unusually large position is what causes lasting damage.
Throughout investing history, some of the largest portfolio mistakes haven’t come from making a bad prediction.
They’ve come from believing that prediction with too much certainty.
Position sizing matters just as much as being right.
More Information Doesn’t Always Mean Better Decisions
Most investors believe more information naturally leads to better decisions.
Sometimes it does.
But often it simply creates more confidence.
Confidence and accuracy are not the same thing.
That’s one reason financial media is so compelling. It constantly gives us the feeling that one more headline, one more forecast, or one more expert opinion will finally provide certainty.
Unfortunately, investing doesn’t work that way.
Markets remain uncertain no matter how much information we consume.
The Real Advantage
The lesson isn’t that information has no value.
It does.
The lesson is that behavior matters more than information.
Long-term investment success has rarely depended on having better headlines than everyone else.
It has depended on developing better habits than everyone else.
Those habits are surprisingly simple:
- Own a diversified portfolio.
- Take only the amount of risk necessary to achieve your goals.
- Avoid making oversized bets based on high conviction.
- Stay disciplined through both good news and bad.
- Accept uncertainty rather than trying to eliminate it.
Ironically, those principles have created far more wealth than a crystal ball ever could.
Because unlike tomorrow’s headlines…
They’re available to every investor today.
