To answer your query ...There are traders here that dabble with a few hundred $$ yes and there are those that habitually invest 5, 6 or 7 digits into a stock(s) ... I personally am aware of approx. a dozen or posters over the last few years who having entered v.large positions v.early have held on to multi-bag ... Roughie calc's estimates that many have made 6-7 digit profits,... some multiple times. No names of course. But this is the exception rather than the rule.
For Example ... Lets say someone invested $50k or $100k into on of the Mountain climber or Gen rerate stocks and held on for a 800% gain or 1000% Gain... There are STT'ers here that invest much larger amount than $50-100k routinely if the story is right.
Anyway Good Luck ... Spent a weekend trawling the Knowledge library and get yourself a strategy worked out ...Trial it on the STT Competition or trade it ...
