The Market Wizard the Market Wizards Respected
“I deal in probabilities, not certainties. So, the key was strategy, not preaching.”Martin Zweig, Winning on Wall Street
That might be one of the most important market lessons ever written.
Most investors are trying to predict.
Where is the market going?
Is the Fed going to cut?
Is this the top?
Is this the bottom?
Is the economy going into recession?
Zweig approached the market differently.
He understood that you don't need certainty to make money. You need probabilities, risk control, and a strategy for what you will do as conditions change.
That distinction is enormous.
Before the 1987 crash, Zweig saw risk increasing, but he didn't pretend he knew exactly what would happen. In fact, he explicitly said he wasn't 100% certain. Instead, he adjusted his strategy, reduced risk, and positioned himself so that if he was wrong, the damage was manageable, and if the market collapsed, he was protected.
That is what great trading looks like.
Observe what the market is actually doing.
Determine the probabilities.
Adjust your exposure as the evidence changes.
Protect yourself when risk rises.
Get aggressive when the odds move back in your favor.
And if you're wondering how respected Martin Zweig was among great traders, go back and read Market Wizards.
Michael Marcus told Jack Schwager that he liked Zweig's market letters. Schwager then made an interesting observation: “Of the traders I have interviewed, Zweig is probably the one most mentioned.” Marcus responded that Zweig was very solid and that you always got something of value from him.
Bruce Kovner, one of the greatest macro traders ever interviewed by Schwager, specifically praised Zweig's risk control and his refusal to act like he could predict the future. Kovner's description is almost a perfect summary of Zweig's philosophy: Zweig observed what was happening and made rational bets from the evidence.
Richard Dennis was asked which analysts he respected.
His response?
“Zweig, is good.”
Paul Tudor Jones was even more direct. When Schwager asked which market advisers he paid attention to, Jones responded:
“Marty Zweig and Ned Davis are great.”
And David Ryan, three-time U.S. Investing Champion and William O'Neil's protégé, included Winning on Wall Street on his recommended reading list for someone serious about becoming a successful stock trader.
There is a reason so many great traders respected Zweig.
He wasn't trying to sound smart by predicting every turn in the market.
He was trying to survive long enough to exploit the opportunities when the probabilities were in his favor.
That's a very different game.
And a much more profitable one.
You don't need to know what the market is going to do next.
You need to know what you're going to do next based on what the market does.
