hello, if I have 80k virtual money and needed to gain as much of return on investments over 5 ASEAN markets (SG,HK,THX,MY,INDO) in 7 days. Any suggestions?

Haha its a school project but Im looking for a sound strategy. Should I diversify or just bet on a small handful of stocks? Lose also no problem as they say failing is the best way to learn. Cheers.

well dont spoonfeed me directly towards completion of my project.

But maybe someone can enlighten me on a method or a website to search public traded companies based on industry? Heard alot about semiconductors and wanna check out the stock performance of a company, but I dont even know one. Maybe like a filtered search based on size, industry, etc. Im new and dont know 50% of the names listed on the market.
