In the current economic climate as it stands right now, I would sink the entire fund into crude oil stock as I notice a trough or flatline in the price, as the price has fallen heavily recently and is bound to shoot back up soon, or at least rise steadily. This would only be a short term investment to increase my capital quickly.
I would then re-invest the earnings into modern manufacturing/robot companies/research, as the popularity of machines such as 3d printers is increasing exponentially, with new functions and revolutionary uses being discovered almost daily. The current potential for profit in that industry is shooting up as more practical uses are found, and more 'problems' are solved by 3d printing with advancement in computer aided design and mass production of the product making it economically viable for smaller business or even personal use/purchase. Thus opening up new markets for businesses (such as simpalized design software aimed at standard end users), revolutionalizing manufacture processes with the ability to produce and customize new parts easily, and even home use for entertainment or household use (such as printing objects or tools to fix or build items).
An example for home use could be something like a known faulty product. Instead of a recall/refund, loosing companies money and angering consumers, free blueprints could be released for fixes and manufactured at home, or available as a cheap service from businesses specialized in this.
A result of this is eco-friendlyness, as consumers are more easily able to fix products cheaply, than have to destroy/repurchase, which is often the cheaper solution, especially in technology.
That is why I would invest in 3D printing companies and research, as there are clear high value potentials for the machines which have not yet been properly researched/tested. And lack of demand/availability/skill now will change as 3d printers become cheaper to produce and more user friendly.
I would not personally spread the investment (ie. keeping some in stocks/commodities/securities/low risk investments) due to its low value, I feel it would hit harder and make more difference as well as producing more profit if targeted at a few companies in a single industry or in a single company, as the possibility for equity value growth is much higher.
