The risk/reward ratio is lower and lower. So movies are the highest risk, highest reward (fastest gain) - and funds are the lowest risk, lowest reward (slowest gain). but RIIIIIIIIGHT in the middle...
Don't underestimate the value of starbonds. They are a fairly safe investment for a reasonable DROI. I use them as a backbone to my port. When I was less than 20 mil, they accounted for 80% of my port. by 100 Mil, they were 60% and now they are about 40-50% of my port. I have gained 38 MIL from starbonds in the batch I currently have. The remaining money can be used for other ventures (movies).
What kinds of movies to invest in - again, it depends on your long term, short term strategy. There also, I have my port broken up. I invest in:
Current releases - whatever is coming out in the next couple of months. Expected DROI is important here, and frequent re-visiting/monitoring/personal gutchecks are required. I don't tend to ride the daytrading wave, as I am playing the adjust, not the player (per se).
Long range wide releases - Looking deeper into the "release schedule" one can find those wide releases that are obviously under/over priced. More reliant on one's own position with respect to how the movie will do and whether or not to hold. Recommended for larger ports who have maxed out the current releases only. (400 mil is still a bit shy. Around 500-550 you should have some slush left over to do this if you wish)
short and long term limited releases. Personally, I don't play these a lot. Only the 5.00+ limited releases get a short from me. I never long them. Usually (90%) they delist waaaaaay lower. I sell before opening weekend anyway, so I am only riding the wave from $5 to 1$.
Penny stocks (0.01-0.05 to 0.10) as a long. I am banking that if I lose 1000-10000/stock, there will be one or two hits that will rise to a wide release someday. I buy 99998 shares of those to keep my holdings easier to manage.
Bottom Stocks (2.00-5.00) with no release. Held in a death spiral, many of these movies will drop to below 1.00. I tend to short them. Buyer beware: there are some obvious ones that one should not short. They WILL explode one day...
Funds and derivatives - to each their own. I think everyone knows what these are and play them, or don't, according to their style.
-----------------
So, with 400 mil, my port might look like:
200 mil starbonds
150 mil current releases
no penny stocks, bottom stocks, limited releases, or post OW adjusted movies
5-8 mil of funds
14 mil OW derivatives
40 mil fun cash - used for IPOs or news of the day.
---------------------
FYI, I use the following number of stocks to keep my port "clean".
Long term holding 99998 shares
Day/short term holding 99999 shares
Wide releases 100000 shares
items to monitor closely (high risk items) 99997 shares
Regular starbonds 20000 shares
Bucket list 19999 shares
---------------------
OK, that's my 2Cents. Think about what you want to do and do it. There is no wrong answer. But I reiterate, starbonds are a must have (IMHO) of any healthy and growing port. With the tools available, these are easy money.
