You can sell this bad luck as a consultancy to those who wish to want a curency or company stock to go down. Make a contract with them, invest in a currency or a company stock they want to go down and charge a results-based commission.
Alternatively you can ask companies to pay you a retainer fee for NOT investing in their stock. As long as they pay you the retainer fee, you don't buy their stock and companies flourish.
I act as an angel here. If I sell my "talant" to competitors who wish to destroy a company, I have act as a devil and a desturctor. I prefer to be an angel and a creator. Yes, I'll be an angel-creator!
