    Sorry, don't wish to appear trolling, but this is opposite to common sense, letting losses run while cutting profits short.
    It is what scared money does, scared to sell in order to wear the loss, and scared to run with it once it recoups.
    Never fall in love with any position or any sector, traders are mercenaries (should be).

    Exactly, it is the opposite of common sense, the opposite of what most do and suggest others do, the opposite of what most computer-generated trading systems executed hypothetically at data that was, suggest you do.

    "Letting profits run" is the ambit of the compulsive gambler. As for (the appearance of) not cutting my losses short, I have my risk proscribed as well as anyone in the markets.

    Most lose in the markets, and do so acting what, to the outsiders, appears as "rationally."

    Why do what most do?

    Thank you for your comments. I totally agree with you on your Kelly comments. On another thread, I ran a Monte Carlo on outcome vs various fractions, from full to Kelly to fractional Kelly and the outcome was obvious. When I used 1/10 Kelly, risk of ruin was zero within my Monte Carlo runs.

    A side note on GE, so you are averaging down? There is a thread on averaging down in which most folks said averaging down were for losers?

    But I do average down.:(:D

    Regards,

    But in another post, you said trading option is not a zero sum game so why do most lose in the market if the outcome always (or mostly) has positive expectancy (not zero or negative sum)?

    Well I must say I'm gobsmacked but hey this is trading and I'm all for listening to another point of view.
    Re GE, being long on this current down trend and adding would not be my method.
    $15 level I would expect a strong bounce or just prior to, if not.......??? :(:thumbsdown::fistbump::wtf: (Punched on the nose, trading account bleeding) :)

    I'm ready to buy more under 13. Now, if DJ delists it from the thirty Industrials, I have to substitute out whatever they replace it with.

    Ha, it wouldn't be a YUGe loss anyhow! I have a lot of different positions running here.

    Just curious, why 13? Don't see any pattern, indicators, trends... to say 13 is a good price?
