Types Of Orders
There are mainly three types of orders that you can execute a trade, market orders, limit orders, and stop loss orders and buy stop orders.
Market Orders - Market orders are to buy or sell a stock immediately. A market order is usually execute at or near the current bid when you sell a stock, or near the ask price when you buy a stock. When you are trading with highly liquidity stocks, that will almost always be the case.
However, if a stock has low volume, the price you see might not be the price you get, there could be big price differences. For example, you see a penny stock trading at $1.50 with low volume, then you buy the stock with market order, the price you actually paid for each share could be $1.70. That's a 13% difference, therefore you should always use a limit order to trade low volume stocks.
Limit Order - is an order to buy or sell a stock at a specific price or better. For example, when you set a limit order to buy a stock at $20, the trade will only be executed if the stock drops to $20 or lower. On the hand, if you want to sell a stock at $20, the trade will only be executed if the price is $20 or higher.
Stop Loss Order - is an order to buy or sell a stock at a specific price to protect a trader from further losses. For example, you buy a stock at $20, and you want to sell the stock if it drops to $18. You will set a stop loss order to sell the stock, and when your stock drops to $18, the stop loss order becomes a market order and your stocks are sold.
For beginners, these are the three core types of orders that you need to be aware of. Once you learn more about the market, you can take advantage of the different types of limit and stop orders such as buy limit, sell limit, buy stop and sell stop.
How to Select Stocks
Choosing a stock broker, executing trades are the easy part of the equation in stock trading and investing online. The hard part is how to select stocks so that you can make profit.
There are three types of stock market participants, traders, investors and speculators.
Long Term Investing
Investors are the ones who buy a stock based on company fundamentals. They study fundamental analysis to increase the odds of choosing a winning stock. They buy a stock based on a company's product, leadership, market position, growth rate, competitive advantage, and the company potentials.
Through the study of fundamental analysis, and by reading a company's income statement and balance sheet, they determine whether or not a company is worth investing.
There are two types of investor, growth and value investors.
Growth Investor
Growth investors buy companies based on their growth. They are more concern about a company's year to year and quarter to quarter revenue growth and sales increase. They often neglect or care less about the company's current profit or net income increase rate.
For instance, Amazon became a 100 billion company long before it achieved a single dollar profit. Amazon investors bought the stock based on the revenue growth and it's potential and they are well paid off.
Value Investor
Value investors are looking for bargains or finding companies that are trading at a historical low price. They use financial matrices such as price to earnings (P/E) ratio, debt to equity (D/E) ratio, price to book (P/B) ratio, free cash flow (FCF), and PEG ratio to determine if a stock is cheap and trading at a bargain.
Usually, investors hold their stocks for the long term, often more than a year and sometimes much longer. The best known investor of all time, Warren Buffett is a value investor and he is known for holding stocks for decades.
Short Term Trading
Traders are those who buy and sell stocks based on technical analysis and stock chart patterns. They buy stocks when the technical indicators signal them to buy and sell stocks when the indicators are telling them to do so.
Usually, the holding period of a stock for traders is very short, anywhere from a few seconds to a few months.
Most traders don't care about company fundamentals. They don't read income statements nor balance sheet. They don't study financial ratios like P/E ratio or the P/B ratio.
Instead, traders focus on the studies of trading systems, psychology, chart patterns, and technical indicators. They believed history repeats itself. What happens in the past on a stock chart will repeat again in the future. If a certain stock pattern was profitable on one stock, it may be profitable for another.
Speculators
Speculators are the third group who participated in the stock market. They usually trade or invest based on tips from gurus, family members or friends, and sometimes on news. Some may even do a little study of the market, but nothing extensive and trick themselves into believing that they can beat the market. These speculators have no trading system or a plan whenever they buy or sell a stock. Most speculators lose most or all of their money that they put into the market, never learned a lesson and have no idea why they lost their money. Needless to say, you don't want to be one of the speculators.
Recommended Books on Trading and Investing
