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.

Though it is called a stock market or equity market and is primarily known for trading stocks/equities, other financial securities - like exchange traded funds (ETF), corporate bonds and derivatives based on stocks, commodities, currencies, and bonds - are also traded in the stock markets.

Pump and dump: this characterises a movement where a group of people with influence will either spread rumours, share hypothetical information or shill (shameless promotion) about a given cryptocurrency project. Their followers will start to buy massively the related cryptocurrency, initiating a « pump » movement, i.e. price starts going up very high and fast. At the same time, the people who spread those rumours will leverage the high increase to do a « dump » movement, i.e. sell the same cryptocurrency (that they had bought at very low prices) at the newly reached high price. The result: the group that initiated the pump will make a large profit, while the people who jumped on the pump train (those who bought in because of FOMO, fear of missing out) will have bought at a high price and are now with an asset that is worth only a fraction of the purchase price

This constitutes the secondary market. The stock exchange earns a fee for every trade that occurs on its platform during the secondary market activity.

In late 2014, legendary self-help and business guru Tony Robbins published a book called Money: Master The Game. In it he explains the strategies and ideas used by the very best investors in the world - hedge fund managers, asset allocators and billionaires - that he gleaned from them during four years of interviews and how their lessons should be applied by the rest of us.

Leverage simply means the use of borrowed money to execute your stock market strategy. In a margin account, banks and brokerage firms can loan you money to buy stocks, usually 50% of the purchase value. In other words, if you wanted to buy 100 shares of a stock trading at $100 for a total cost of $10,000, your brokerage firm could loan you $5,000 to complete the purchase.

We used a five-star-based rating system to rate companies in the discount stock brokers list above. The best brokerage firms would get the highest, five-star rating. In 2020 not a single firm got five stars, however six brokers were rated at four and half stars. Any brokerage house with two- or one-star rating should be avoided. Three-star rated firm is perfectly fine, but there are, probably, better options for investors to consider. All companies with three and half stars and higher are recommended for at least one category of investors.


Even when the stock price has performed as expected, there are questions: Should I take a profit now before the price falls? Should I keep my position since the price is likely to go higher? Thoughts like these will flood your mind, especially if you constantly watch the price of a security, eventually building to a point that you will take action. Since emotions are the primary driver of your action, it will probably be wrong.
Whatever happens on a stock exchange and no matter how much influence computers, algorithms and high frequency trading may have, human nature will always have an important role to play. Typically, human nature becomes more important when momentum is changing and there is excitement or panic in the air. It would seem wise to try and understand this mass psychology or group thinking which is often referred to by investors as the madness of crowds.

When selecting a new online broker, the first step is to read reviews and see what features matter most to you. Are low-cost trade commissions most important? What about customer service, the trading platform, mobile app, investment research, ease of use, or education? With many brokers specializing in different areas, it is crucial to evaluate all categories by reading full-length broker reviews.
Funding a IRA, Roth IRA, or other retirement account with no annual fees is an extra perk many online brokers offer. There is no reason why you should pay an annual fee to have an retirement account. If managing your own portfolio is not of interest, all full-service brokers offer optional advisory services as well. Furthermore, robo-advisors are growing in popularity. Once again, the experience at larger established brokers is going to be superior to smaller brokers.
