armin, you need to not stress you with that!
and it has simple reasons:
first, everyday there are thousands of stocks going up, many of them more than 100%.
you CANT get all these runners. i myself dont get em, but i try to figure out the next and buy early.
but i dont stress me by seeing them and not being part of it. better i think of how great that these chances exist here
and that we can get one in future.
second, most of these huge runners consist of one spike coming out of nowhere because of news. you cant predict them before.
last summer there was one stock i watched. it ran 10.000% in one day. imagine that! before it was flat, no volume, no trading. suddenly RM news and some big players jump in starting the wave... . no way in getting upset if you didnt get in before, there was no way of knowing that!
the only, risky, thing you could have done is to see how it run and jump on. but its always dangerous to jump on a running train.
all these people who buy "dead" stocks as lottoplays... what do you think how many stay dead or go down more for every one which pops hundereds of percent??!
in the longterm you will lose on these trades, so stay to TA and try to catch "smaller" (still way over 100% possible) gains but surer ones.
