But TJ, you just confused me, which with me is always easy to do. :-)) When
you are in regular portfolio mode and you are trading, say, a market timing
system where you buy x no. of stocks at the same time, when you get a buy
signal, you want to chose the x-highest ranked stocks based on whatever
criterion/criteria you decide to rank your stocks by. You certainly don't
want to choose the x stocks at the top of the alphabetical list. In other
words, you are buying when something happens, and your system is
signal-based, yet you want to buy the highest ranked stocks, too. So, you do
NOT want to use a rotational system; you want to use a signal-based system
that also ranks stocks. According to your message below, what I describe
above seems to be a hybrid of regular mode and rotational mode. So, the
buy/sell times DO depend on signals, not ranking. Ranking is just a
secondary but important part of market timing signal-based type of systems.
Is this not correct?
