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
Sell walls: the action of artificially keeping the price of a cryptocurrency asset low by placing a large sell order. Large financial operators or investors (nicknamed « whales ») may want to artificially keep the price of a cryptocurrency low so that they can keep accumulating quietly, without causing a sharp rise in price. These are called « walls » because on exchanges, the graphics showing offer and demand will show a very high « wall » on the offer size. The mechanism is that the investor will put a very large sell order (usually 100 to 1000 times more cryptocurrency units than regular orders). Because of how exchanges operate, the sell will only take place if there is sufficient demand to fulfil the entire order, so smaller operators who have a real need/urge to sell would have to sell below that wall (i.e. cheaper) to make sure they can get paid. This will cause a condition where the price will stagnate, allowing those whales to put as much smaller buy orders as they need. Sell walls may be removed once the buying whales have reached their objectives.
Investor Protection: Along with wealthy and institutional investors, a very large number of small investors are also served by the stock market for their small amount of investments. These investors may have limited financial knowledge, and may not be fully aware of the pitfalls of investing in stocks and other listed instruments. The stock exchange must implement necessary measures to offer the necessary protection to such investors to shield them from financial loss and ensure customer trust.
Discount brokers used to be the exception, but now they're the norm. Discount online brokers give you tools to select and place your own transactions, and many of them also offer a set-it-and-forget-it robo-advisory service too. As the space of financial services has progressed in the 21st century, online brokers have added more features including educational materials on their sites and mobile apps.
Buy & Sell Orders – each exchange has their own method of placing buy or sell orders but generally speaking the interface is similar as that of a trading application. This requires some familiarisation with the exchange interfaces. In essence, there are two sides on any exchange: people who want to sell, and people who want to buy. Everybody can sell or buy at the price they want, but obviously buyers want to buy at the cheapest price and sellers want to make the biggest profit, which means that eventually a middle point will be reached where the transactions take place. It’s common for people to cancel their sell or buy orders and put in place new ones by 0.00001 increments just to get the « top » place on the buy or sell list, i.e. sell at the « lowest price » or buy at the « highest price » in order to have their order fulfilled. Once you buy (or sell) the balances get adjusted accordingly

Work-based retirement plans deduct your contributions from your paycheck before taxes are calculated, which will make the contribution even less painful. Once you're comfortable with a one percent contribution, maybe you can increase it as you get annual raises. You won't likely miss the additional contributions. If you have a 401(k) retirement account at work, you may already be investing in your future with allocations to mutual funds and even your own company's stock.
In terms of the beginning investor, the mutual fund fees are actually an advantage relative to the commissions on stocks. The reason for this is that the fees are the same, regardless of the amount you invest. Therefore, as long as you meet the minimum requirement to open an account, you can invest as little as $50 or $100 per month in a mutual fund. The term for this is called dollar cost averaging (DCA), and it can be a great way to start investing.
The stock exchanges also maintain all company news, announcements, and financial reporting, which can be usually accessed on their official websites. A stock exchange also supports various other corporate-level, transaction-related activities. For instance, profitable companies may reward investors by paying dividends which usually comes from a part of the company’s earnings. The exchange maintains all such information and may support its processing to a certain extent. (For related reading, see "How Does the Stock Market Work?")
C (Fair) - In the trade-off between performance and risk, the stock has a track record which is about average. It is neither significantly better nor significantly worse than most other stocks. With some funds in this category, the total return may be better than average, but this can be misleading since the higher return was achieved with higher than average risk. With other funds, the risk may be lower than average, but the returns are also lower. In short, based on recent history, there is no particular advantage to investing in this fund.
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. (For related reading, see "What's the Difference Between the Equity Market and the Stock Market?")
Buy “the basket”: Can’t decide which of the companies in a particular industry will be the long-term winner? Buy ’em all! Buying a basket of stocks takes the pressure off picking “the one.” Having a stake in all the players that pass muster in your analysis means you won’t miss out if one takes off, and you can use gains from that winner to offset any losses. This strategy will also help you identify which company is “the one” so you can double down on your position if desired.
