100% math, good or bad?

Quote from StockBagger:

I have backtested the dow 30 stocks and SPY from the beginning of the year and have done quite well.

Backtesting must cover at least one market cycle and preferably two. Since this data is what you used to tune your system, it must be validated with at least one market cycle outside of the two you used to develop you system.

"Since the beginning of the year" is woefully short for an adequate test. Even after you have simulated your system you must prototype it. You do this by paper trading it. Only then do you commit money to your system. Both backtesting and paper trading have differences from reality which have been covered elsewhere on this forum.

Quote from deadbroke:

JoePaterno's had a difficult childhood. The only thing that works on Joe is Psychology.

You see, Joe, a HERD member from his father's side, but his Ma was a lioness who was a master of reverse psychology - Joe, a child of particularly intemperate disposition, loved to pull pubic hairs from under girls' dresses and reveled in their shrieks of agony.

At age 7, when Ma returned home late one night after having left little Joe in the capable hands of Mary, their babsitter, she beheld them both outside by the pool with Mary pleading and begging little Joe to go to his room as it was way past his bedtime. Joe wouldn't budge.

Ma sent Mary home and went into the house and returned with a blanket and pillow which she handed to little Joe and said, "have a good night, see you in the morning. Love you"

Little Joe was in his room and in bed in under 5 minutes.

Can you suggest the story of how JP got the complain and ignore button so confused? Does he stutter around six when counting letters of words?
