Reminiscences of a Stock Operator published in 1923 offers timeless wisdom for all investors and traders:
* Never act on tips.
* Use a system and don't deviate from it.
* Never buy a stock because it has had a big decline from its previous high.
* If a stock doesn't act right don't touch it; because, being unable to tell precisely what is wrong, you cannot tell which way it is going. No diagnosis, no prognosis. No prognosis, no profit.
* Don't blame the market for your losses.
* Never add to a losing position. A losing position means you were wrong.
* Stocks are never too high for you to begin buying or too low to begin selling. But after the initial transaction, don't make a second unless the first shows you a profit.
* Always sell what shows you a loss and keep what shows you a profit.
* Don't argue with the tape. Do not seek to lure the profit back. Quit while the quitting is good--and cheap.
* There is only one side to the stock market; and it is not the bull side or the bear side but the right side.
* The speculator's chief enemies are always boredom from within.
* A man must believe in himself and his judgment if he expects to make a living at this game.
* Bulls and bears make money, but pigs get slaughtered.
* Use money management at all times.
* Establish your trading plan before the markets open.
* Detailed your plan for each trade.
* Establish entry and exit points and understand risk reward rations.
* Accept small losses as part of the game if you want to win.
* Trade markets from the short side.
* Stand aside from a position, knowing you have taken a position.
* Develop a trading plan for each potential situation you may face.
* Do not look at quotes during the day.
* Do not concentrate on break-even levels when you are losing.
* Don't liquidate a winner to keep a loser.
* Develop and maintain an exit plan. Follow this plan with rigid discipline.
* Sustain your patience. Big movements take time to develop.
* Don't be overly curious about the rationale behind a move. The key to wealth in trading is simplicity.
