and yet experienced traders say not to hold a trade for longer than 30 days
some even more experienced traders will not even hold overnight and the most experienced only trade the index.

there was a stock which was 20c last year and tipped by brokers to hit 40c. it is now 13c. It gave me many happy trades last year which add up to a nice overall profit and about to buy it again. I know and trust the management team. fundamentals are good yet market has rated it down.
doesn't matter as long as you arent holding it on the way down. just gives a better buying opportunity. will it hit 40c. dont know. short term trend is back up and will see where we end up this time.

just trading the short term chart and the rest dont matter. for me this is the fun of trading.
