Here are some other
non spoiler tips I've found:

Destroying competitors:
If you invest in a company and then go wreck their competitor's stuff, it should increase your stock value. For example: Sink money into AirEMU, prefferably when the stock is already low, then go blow up FlyUS planes. Or buy CluckinBell stock and go rob and destroy a few Burgershot stores. Or invest in one car company, then destroy their competitor's cars, preferably at their dealership. Note: We've been experimenting with this and it doesn't exactly pan out as expected. You can't enter most stores such as Burgershot, and can't find these supposed car dealerships or other company buildings. And we've spent hours blowing up GoPostal and Pisswasser trucks but never really saw their or their competitor's stock fluctuate.
Reliable stocks:
I've seen this stocks reliably spike up and down. Invest in them when they're low:
TacoBomb
Fleeca
BankOfLiberty
MazeBank
Insurance companies:
Per user iNewWorldOrderi, if you invest money in AUG AugeryInsurance, then go around damaging/destroying cars, it will drive your stock value up.
Untested theories:
How MorsMutualInsurance relates to you going around killing people.
How the various lawfirm stocks are affected by what you do.
If the bank stocks drop if you rob their ATM users.
If you can make GoPostal, PostOP, and GruppeSechs stock drop by jacking their company trucks.
If listening to a radio station's stock makes the value go up, or maybe you can go to the roof of their building and blow up the antenna.
