make some good increases as you move 'further' out in buying stocks that are opening within the next 3-4 months.
With a port your size, I would not hold TOOO many stocks that are further out than 3-4 months, since these will offer the most movement for you. With summer coming, you'll see some big blockbuster movies opening... as the studios release many good movies during May-July.. and a bit in August perhaps.
Make sure you own those stocks that come out during that time, pick the ones you think will be winners if the prices are such that make it worth while.
Personally, (and no offense to OlegMax) I think once your port passes the $20-$30M mark, it's harder (but not impossible) to grow it by 1% a day... that's a 30% increase in a month... and I think it's hard... that would be a $50M port growing by $15M in one month, and you'd have to be really hopping to do that...again... I'm not saying it can't be done...just more difficult.
I will say that Grory built a port into $1 BILLION in a year... so it CAN be done... I think you should look at your holdings... make sure you have shares of the big films coming... if there's room in the prices to grow still (short them if you think they are over priced). If you can earn 5% a week, that's still not a bad increase... depending on what you hold...
Either way... there's nothing wrong with working hard as OlegMax said, and work at 1%/day, that's still a very good goal.
I think a lot has to do also, with how much time you can devote to HSX... playing and earning a lot requires time, so depending on your schedule, you have to factor that in as well.. If you can't play as much, then don't be too hard on yourself if you're not doing the 1% a day.. set your own goal for yourself and play against yourself...don't worry about what others are doing... no one has the same time to play as the other guy.
Good luck.
