Network effects -- In simple terms, a network effect occurs as more people use a service or product, and the product or service itself becomes more valuable and desirable as a result. Think of companies like Facebook (NASDAQ:FB). As more and more people join Facebook, it becomes more difficult for people not to use the platform in their daily lives.
Some scammers will buy up a ton of some near-bankrupt, almost lifeless penny stock, then use lies and exaggerations to push the share price much higher. They might say the company is about to get some huge business deal with Google or their neighbor just struck gold in their similar mine, or they are going to land a major FDA clearance. That typically helps increase the value of the penny stock, which creates a profit for the promoter or scam artist. As the shares increase in value, they sell their holdings. These shares usually collapse back down to near-worthless status once the promoter has taken their profits and moved on. 

Dividend investing refers to portfolios containing stocks that consistently issue dividend payments year-in and year-out. These stocks produce a reliable passive income that can be especially helpful in retirement. Dividend reinvestment is a way to accelerate portfolio growth. Still, you can't judge a stock by its dividend price alone. Sometimes companies will increase dividends as a way to attract investors when the underlying company is in trouble. Dividends are taxable.

The reality is that in the modern world - especially with the power of the internet - there is very little information that is not in the public domain somewhere. However, the world now has information overload. Whilst the information might be available, few people now have the time to find or understand it. The people who know these things and can 'join the dots' have regular opportunities for stock market investment.

Brokers are either full-service or discount. Full-service brokers, as the name implies, give the full range of traditional brokerage services, including financial advice for retirement, healthcare and everything related to money. They usually only deal with higher-net-worth clients, and they can charge substantial fees, including a percent of your transactions, a percent of your assets they manage, and sometimes a yearly membership fee. It's common to see minimum account sizes of $25,000 and up at full-service brokerages. Still, traditional brokers justify their high fees by giving advice detailed to your needs.

It is also worth trying to keep up to date with the latest thinking related to the area of investment that you are trying to specialise in. Therefore, if you plan to invest in defensive or income stocks, for example, it would be wise to read regularly about value investing and dividends.

Perhaps you could subscribe to one or more trade publications that relate to the sector(s) that you are most interested in.

When investing in the stock market, you have to think long term and avoid the temptation to check your portfolio several times per day. All this will do is waste your time, stress you out, and increase the odds that you will make a big mistake and sell at the wrong time. Plan to set up automatic contributions to your investment so you can buy more investments no matter where you are.
Risk tolerance is a psychological trait that is genetically based, but positively influenced by education, income, and wealth (as these increase, risk tolerance appears to increase slightly) and negatively by age (as one gets older, risk tolerance decreases). Your risk tolerance is how you feel about risk and the degree of anxiety you feel when risk is present. In psychological terms, risk tolerance is defined as “the extent to which a person chooses to risk experiencing a less favorable outcome in the pursuit of a more favorable outcome.” In other words, would you risk $100 to win $1,000? Or $1,000 to win $1,000? All humans vary in their risk tolerance, and there is no “right” balance.
In the professional world, one of the key concepts is diversification. Harry Markowitz is a Nobel prize winning economist and one of his major discoveries was that adding new asset classes can dramatically alter the overall risk profile of a portfolio. His finding was that a portfolio that contained very low risk assets would normally benefit from lower volatility and higher returns if a higher risk asset was added. This is due to the likely lack of correlation between high and low risk asset classes.
Building a diversified portfolio is the priority for beginners who should consider adding index funds that capture the broader market, Swope says. Mutual funds and ETFs are the easiest solutions since they own hundreds to thousands of stocks and are less volatile than individual stocks. ETFs tend to have low minimums, allowing investors to spread their first $10,000 between a few funds and gain access to a variety of areas in the market, he says.
This is an excellent learning experience and one that is vital to the long-term profitability of anyone in the stock market. To get the real experience, purchase some graph paper and chart the stock price movements each day by hand. Learn to compare this with the overall movements of the equity market or index and a whole new world of investment and money will begin to open up to you!
However, it might be best to not become too much of a market "expert". Some of the most famous and successful investors of all time, such as Peter Lynch, the famed manager of the huge Fidelity Magellan fund. He suggested that looking for clues in normal life is a great way to find opportunities. Lynch used to closely follow the shopping habits of his wife to see what brands people were buying. He believed that most people working professionally on the NYSE lived in a bubble.

Finally, keep in mind that if trading on margin—which means you're borrowing your investment funds from a brokerage firm (and bear in mind that margin requirements for day trading are high)—you're far more vulnerable to sharp price movements. Margin helps to amplify the trading results not just of profits, but of losses as well if a trade goes against you. Therefore, using stop losses is crucial when day trading on margin.
One constant principle of investing is that markets fluctuate. Stock prices will rise and fall for a number of reasons: the economy, investor sentiment, political uncertainty at home or abroad, energy or weather problems, or even corporate scandals. This means market performance isn’t always predictable. That is why diversification, or spreading the investments in your portfolio among different asset classes and across different sectors within each class, is such an important strategy. Diversification is a time-tested way to manage risk.
PEG ratio -- Companies grow at different rates, and failure to take this into account is one of the key shortcomings of the P/E ratio. The price-to-earnings-growth ratio, or PEG ratio, levels the playing field. Simply divide the company's P/E ratio by its projected earnings growth rate. For example, a company with a P/E of 30 and a 15% expected growth rate would have a PEG ratio of 2.0. Like the P/E ratio, the PEG ratio is most useful for comparing companies in the same industry but with different growth rates.

How much money should I invest in stocks? If you’re investing through funds — have we mentioned this is our preference? — you can allocate a fairly large portion of your portfolio toward stock funds, especially if you have a long time horizon. A 30-year-old investing for retirement might have 80% of his or her portfolio in stock funds; the rest would be in bond funds. Individual stocks are another story. We’d recommend keeping these to 10% or less of your investment portfolio.
You’ll come across an overwhelming amount of information as you screen potential business partners. But it’s easier to home in on the right stuff when wearing a “business buyer” hat. You want to know how this company operates, its place in the overall industry, its competitors, its long-term prospects and whether it brings something new to the portfolio of businesses you already own.
