Some of these tips will help you build your port faster, so take and use the ones you may find helpful...
Personally, I think playing openers each week will build your port faster than just about any other way of playing style (except maybe daytrading, which is very tricky for many players). BUT, remember too....you can ALSO LOSE $$ when you pick an opening movie wrong...but low risk = low gain (usually).
Maybe think more "short term." Buy a stock (or short it) then make some $$ on it, and move on.
Personally, I have always tried to 'max' out on an opener when I play it. Buy or short as much as you can afford - if you think you can make $$ on it. There is nothing more frustrating to me, than to only buy 5,000 shares of something, knowing I could have afforded more, and then make only $75,000 on the adjust, when I could've made $500,000 if I would have bought as much as I could afford, or maxxed out.
Remember... you can make JUST as much money on a movie that's priced at $20 if it adjusts up 5 points, as you can on one that is priced at $70, and adjusts up 5 points - so keep that in mind. The only difference is, you don't tie up as much cash waiting for them to adjust. Remember, the old addage "PPDM", which means "Price Paid Doesn't Matter." And don't be jealous because someone else paid $10 for a stock 6 months ago and it's now worth $70... when both movies adjust 5 points - you both make the same amount of $$ on the opening weekend adjust as th player who paid $10 for it.
You can also click on the tab "Earn H$" there are ways to earn FREE cash for your port!...and every little bit helps your port when starting out...so click there too. Take advantage of any opportunity to earn extra $$ that's out there. If you find a movie IPO's one day, and you think the price of it may go up (something like Ironman 8, etc.) then you may want to take a shot at it...buy it and hold it for the 'ride' UP of the price...but once you've made some $$...sell it and move on... why keep this stock and tie up lots of your cash for a movie that's opening in 2-3 years? Even if you KNOW it will be a huge blockbuster at that time, it doesn't make sense with a small port.
You can make money shorting stocks too if you think their prices will DROP..so learn to earn $$ by shorting stocks as well as buying them. When I started playing we could not short stocks, but now players can earn $$ when prices go up OR down...take advantage of adjusts of openers that may drop in price after opening weekend, as you can make some fast money too by shorting openers after they adjust in price.
Some of these suggestions are obvious, but it may help you to look again at things you may have forgotten about as you play. Good luck.
