But this isn’t your typical market, and you can’t show up and pick your shares off a shelf the way you select produce at the grocery store. Individual traders are typically represented by brokers — these days, that’s often an online broker. You place your stock trades through the broker, which then deals with the exchange on your behalf. (Need a broker? See our analysis of the best stockbrokers for beginners.)
Diversification allows you to recover from the loss of your total investment (20% of your portfolio) by gains of 10% in the two best companies (25% x 40%) and 4% in the remaining two companies (10% x 40%). Even though your overall portfolio value dropped by 6% (20% loss minus 14% gain), it is considerably better than having been invested solely in company E.
There are many fees an investor will incur when investing in mutual funds. One of the most important fees to consider is the management expense ratio (MER), which is charged by the management team each year, based on the number of assets in the fund. The MER ranges from 0.05% to 0.7% annually and varies depending on the type of fund. But the higher the MER, the more it impacts the fund's overall returns.
As a primary market, the stock market allows companies to issue and sell their shares to the common public for the first time through the process of initial public offerings (IPO). This activity helps companies raise necessary capital from investors. It essentially means that a company divides itself into a number of shares (say, 20 million shares) and sells a part of those shares (say, 5 million shares) to common public at a price (say, $10 per share).

Finally, one point to mention is that a given cryptocurrency can be listed in more exchanges, with different listing prices (see below – Arbitraging). The best place to look for a cryptocurrency listing in term of total market capitalisation is Coinmarketcap. Cryptocurrencies are listed per descending order of market capitalisation; the site also allows to deep-dive on each cryptocurrency to see their value over time and where they are listed. Some cryptocurrencies may be listed on several exchanges but only 1 or 2 exchanges may see the critical mass of transactions taking place.

A stock split is when a company increases its total shares by dividing up the ones it currently has. It is typically done on a 2:1 ratio. For example, if you own 100 shares of a stock priced at $80 per share, after the split, you'll have 200 shares priced at $40 each. The number of shares changes, but the value remains the same. Stock splits occur when prices are increasing in a way that deters and disadvantages smaller investors. They can also keep the trading volume up by creating a larger buying pool to trade. If you invest in a stock, expect to experience a stock split at some point.
