A stock's market capitalization (cap) is the sum of the total shares outstanding multiplied by price. For example, if a company has 1 million outstanding shares priced at $50, its market cap would be $50 million. It has more meaning than the share price because it allows you to evaluate a company in the context of similar-sized companies in its industry. A small-cap company with a capitalization of $500 million shouldn't be compared to a large-cap company worth more than $10 billion. Here are how companies are generally grouped:
While most online brokers do not offer international trading, some do. Nearly every broker supports trading American depositary receipts (ADRs), which offers US investors an easy, simple way to invest in foreign companies. However, if you want to buy physical shares of an international company, then you need to do your research. Interactive Brokers is the leader in this space but is built for professionals. For casual investing, both Fidelity and Charles Schwab offer international stock trading.
The biggest obstacle to stock market profits is an inability to control one’s emotions and make logical decisions. In the short-term, the prices of companies reflect the combined emotions of the entire investment community. When a majority of investors are worried about a company, its stock price is likely to decline; when a majority feel positive about the company’s future, its stock price tends to rise.
Every online brokerage firm on the list above has its strengths and weaknesses. It might be ideal for one customer and at the same time might not work for someone else. Before opening an account, there are a lot of parameters to consider besides commissions, well-known brokerage name, and pretty website. Some of the most important of these parameters are surcharges and fees; friendliness to client's knowledge level (perhaps one is a beginner? or needs a professional-level trading platform?); availability of investment products a client wants to buy (for example forex, futures, or NTF mutual funds) as well as availability of online community, virtual trading, and discounts. We suggest to investors to take a time to read brokerage reviews, and see for themselves if a particular firm is the right fit.
To facilitate this process, a company needs a marketplace where these shares can be sold. This marketplace is provided by the stock market. If everything goes as per the plans, the company will successfully sell the 5 million shares at a price of $10 per share and collect $50 million worth of funds. Investors will get the company shares which they can expect to hold for their preferred duration, in anticipation of rising in share price and any potential income in the form of dividend payments. The stock exchange acts as a facilitator for this capital raising process and receives a fee for its services from the company and its financial partners.

Most of these services offer some form of free portfolio tracking - this enables you to create a portfolio and track it properly to see how you do with no money on the line. This used to be known as paper trading in the 'good old days' before 2001. This kind of exercise can be a good way to learn and play around with things without being either serious or costly.
Phrases like “earnings movers” and “intraday highs” don’t mean much to the average investor, and in many cases, they shouldn’t. If you’re in it for the long term — with, say, a portfolio of mutual funds geared toward retirement — you don’t need to worry about what these words mean, or about the flashes of red or green that cross the bottom of your TV screen. You can get by just fine without understanding the stock market much at all.
Stock brokers are people or firms licensed to buy and sell stocks and other securities via the stock market exchanges. Back in the day, the only way for individuals to invest directly in stocks was to hire stock brokers to place trades on their behalf. But what was once a clunky, costly transaction conducted via landline telephones now takes place online in seconds, for a fraction of what full-service brokers used to charge for the service. Today, most investors place their trades through an online brokerage account. (A little lost? Check out our explainers on brokerage accounts and buying stocks.)

Finally, you’re going to be looking for catalysts or roadblocks to growth for each company. This means looking in the financial news, reading analyst reports and management presentations. By this time in the process, maybe you’re only looking at four to six companies in a sector so this level of deep research won’t take more than a couple of hours.
In addition to knowledge of basic trading procedures, day traders need to keep up on the latest stock market news and events that affect stocks—the Fed's interest rate plans, the economic outlook, etc. So do your homework. Make a wish list of stocks you'd like to trade and keep yourself informed about the selected companies and general markets. Scan business news and visit reliable financial websites.

Then what? You might be new to investment but already wealthy, what do the super rich do to diversify? They use real estate in New York, London and the Cote d'Azure as a reserve currency. They change their country of residence to a tax haven, pursue naturalization through one of the EU citizenship by investment countries and then buy a sports franchise. Sorry, the sports franchise isn't actually an investment...
Altcoins are tied to the Bitcoin markets, if Bitcoin takes a hit there’s a high probability that altcoins will also suffer, so you’re looking at that moment to jump in: when others are panic selling, you should be investing. Also, there is a sort of tidal lock between altcoins and Bitcoin. Never take a green market (prices going up) for your preferred project finally breaking through. It could just be that the rise of Bitcoin price brings everything up organically, so you may be advise to check whether your project’s value in Bitcoin (not in US dollars or any other fiat currency) has changed or if it has stayed more or less the same. This is usually visible on cryptocurrency only exchanges where Bitcoin is often the de-facto main exchange currency.
By understanding your risk tolerance, you can avoid those investments which are likely to make you anxious. Generally speaking, you should never own an asset which keeps you from sleeping in the night. Anxiety stimulates fear which triggers emotional responses (rather than logical responses) to the stressor. During periods of financial uncertainty, the investor who can retain a cool head and follows an analytical decision process invariably comes out ahead.
Regarding your private keys, can either keep them on a software wallet, or on a hardware wallet. The software wallet is the easiest way for beginners, but it implies that you have a computer that is properly secured (strong password, antivirus etc.) and that you do backups of your data. Remember, if you lose your private keys, the money is gone forever. As you get into cryptocurrencies more seriously, you will inevitably look for a hardware wallet, which is a dedicated device resistant to hacking where you can store your private keys (or to say it in an easy way, your crypto assets/invested money). I have already written an article on a hardware wallet, the TREZOR (see here). The most common wallets are the TREZOR and the Ledger Nano S. The TREZOR has a new model being sold from January 2018 (Model T) which will support much more currencies than the current TREZOR. The Ledger Nano S has more integrations currently, but I would recommend to wait for the TREZOR T to judge properly. Those devices usually cost around 100 USD, so once you have more than 100 USD to protect it starts making sense to get one.
Balances and confirmations – this is where you fund your exchange accounts, and also where the money you trade will be deposited. Bear in mind that when you send cryptocurrency to an exchange, or you withdraw cryptocurrency to your personal wallet, there will be a delay that varies per exchange. Each exchange will wait for a certain number of confirmations before effectively releasing your funds, this happens on the blockchain.
What would make me sell: Sometimes there are good reasons to split up. For this part of your journal, compose an investing prenup that spells out what would drive you to sell the stock. We’re not talking about stock price movement, especially not short term, but fundamental changes to the business that affect its ability to grow over the long term. Some examples: The company loses a major customer, the CEO’s successor starts taking the business in a different direction, a major viable competitor emerges, or your investing thesis doesn’t pan out after a reasonable period of time.
