There is one simple way to keep in mind when you are a beginner and want to diversify a small amount of money. 

And that simple way is to invest in mutual funds or exchange-traded funds.

For the most part all EFTs are essentially a form of mutual funds which can be bought and sold just like normal stocks on online brokers or whatever investing form you choose. 

EFTs like a mutual funds contains a many stocks in one purchase. And sometimes some EFTs contains hundreds of stocks.

These stocks in these EFTs are adhere to particular criteria, like shares of some companies that are a part of a stock market index, a good example will be a S&P 500.

However EFTs, unlike mutual funds can have some high investment minimums.
