The mechanics of the swing trump the results of the at-bat.

"Fight? No, not yet. Not until me and Harvey get the rules straightened out.
--Butch Cassidy 

I remember why I wanted to be a trader.  I figured that the easiest way to make money was to stand next to the cash register. 

As I realized throughout my career, there's a reason consistent producers get paid the big bucks.  Flashy bets and big swings sometimes connect, but in the end, a disciplined approach pays the bills. 

I've tripped plenty through the years, missteps that almost cost me my livelihood, but I persevered, climbed the ladder, and morphed those mistakes into valuable lessons. 

I matured as a vice-president at Morgan Stanley (MS), a Managing Director at the Galleon Group, and as the President of Cramer Berkowitz, a $400 million hedge fund.  My approach varied, but in the end, certain rules allowed me to stay in the game. 

These are those rules. 

Respect the price action, but never defer to it. 

Our eyes are valuable tools when trading, but if we deferred to the price action, stocks would be "better" up and "worse" down, and that's a losing proposition. 

Discipline trumps conviction. 

No matter how strongly you feel on any given position, you must remain disciplined when trading.  Always try to define your risk and never believe that you're smarter than the market. 

Opportunities are made up easier than losses. 

It's not necessary to play every day; it's only necessary to have a high winning percentage on the trades you choose to make.  Sometimes the ability not to trade is as important as trading ability. 

Emotion is the enemy when trading. 

Emotional decisions have a way of coming back to haunt you.  If you're personally attached to a position, your decision-making process will be flawed.  Take a deep breath before risking your hard-earned coin. 

Zig when others zag. 

Sell hope, buy despair, and take the other side of emotional disconnects (in the context of defined risk). If you can't find the sheep in the herd, chances are that you're it. 

Adapt your style to the market. 

Different investment approaches are warranted at different junctures and applying the right methodology is half the battle. Identify your time horizon and employ a risk profile that allows the market to work for you. 

Maximize your reward relative to your risk. 

If you're patient and pick your spots, edges will emerge that provide an advantageous risk/reward.  Proactive patience is a virtue. 

Perception is reality in the marketplace. 

Identifying the prevalent psychology is a necessary process when trading. It's not "what is," it's "what's perceived to be" that dictates supply and demand. 

When unsure, trade "in between." 

Your risk profile should always be an extension of your thought process. If you're unsure, trade smaller until you find your comfort zone. 

Don't let your bad trades turn into investments. 

Rationalization has no place in trading. If you put a position on for a catalyst and it passes, take the risk off—win, lose, or draw. 

There are more rules but I've found these to be the most common threads through the years.  Each of us has a unique risk profile and time horizon and it’s important that they remain in sync.

Find a style that works for you and allow for an ample margin of error. Any trader worth his or her salt has endured periods of pain, but if we learn from mistakes, they morph into lessons.

Good traders know how to make money and great traders know how to take a loss.  And regardless of your P&L, remain balanced; if you don’t stay humble, the market will do it for you.
