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 $$ when you pick an opening movie wrong.
Maybe think "shorter term" as a player. Buy a stock (or short it) make some $$ on it, and move on. My advice for NOW, is DO NOT hold or buy ANY movie stock that is further out than 90 days.... Why? because you'll tie up your cash, and you won't be able to use $$ to buy other good deals (like openers, IPO's, etc.)
I have always tried to 'max' out on an opener when I played it. Buy as much as you can afford if you think you can make $ on it. There was nothing more frustrating to me, than to only buy 5,000 shares of something, knowing I could have afforded more, and then make only $75,000 on the adjust, when I could've made $500,000 if I would have maxxed out.
Remember... you can make JUST as much money on a movie that's priced at $20 if it moves up 5 points, as you can on one that is priced at $70, or adjusts up 5 points - so keep that in mind. The difference is, you don't tie up as much cash waiting for them to adjust. Remember, the old addage "PPDM", which means "Price Paid Doesn't Matter." And don't worry because someone else paid $10 for a stock 6 months ago and it's now worth $70... when both movies adjust up or down (if short) 5 points - you both make the same amount of $$ on that opening weekend adjust.
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 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 if you want to meet goals.
AGAIN...think "shorter term" gains to build your port quicker.
Remember you can make money shorting stocks too if you think their prices will DROP..so learn to earn $$ by shorting stocks as well as buying them...take advantage of adjusts of openers that typically drop in price after opening weekend, as you can make some fast money too by shorting openers after they adjust in price.
You have to get MORE active playing if you want to reach your goal. I understand that everyone doesn' have the same amount of time to play, but you can put your $$ to work for you, it's just sitting in your port now... use it to make more $$.
