At the same time, there are literally hundreds of thousands of individuals who buy and sell corporate securities on one of the regulated stock exchanges or the NASDAQ regularly and are successful. A profitable outcome is not the result of luck, but the application of a few simple principles derived from the experiences of millions of investors over countless stock market cycles.
Use stop-loss orders: Possibly the single most important tactic for investing well in penny stocks is to use stop-loss orders. Basically, you commit early on to immediately sell your shares if the price dips to a certain point. If you stick to this self-imposed rule, you limit your downside, but at the same time you remain open to the tremendous upside that penny stocks could provide. You may see better overall trading results by selling your losing positions very early and letting your gains run.
The least demanding way to invest in the stock market is to invest through a fund. There are two types of funds. First is the actively managed mutual funds which have higher fees—92% of these funds fail to beat the underlying index over any three-year period. The second type is the index tracking fund, which typically has lower costs and is more effective in matching the growth of the stock market. This means they are growing in popularity because of the higher return on investment you receive. You should also use the most tax efficient way to invest: using your Investment Retirement Account (IRA) first. It’s best to invest in a low-cost, index-tracking fund through your tax-free IRA.
The stock market is made up of exchanges, like the New York Stock Exchange and the Nasdaq. Stocks are listed on a specific exchange, which brings buyers and sellers together and acts as a market for the shares of those stocks. The exchange tracks the supply and demand — and directly related, the price — of each stock. (Need to back up a bit? Read our explainer about stocks.)
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.
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.
Most Wall Street pundits will tell you it's impossible to time the stock market. While it's unrealistic to think you'll get in at the very bottom and out at the very top of a market cycle, there are ways to spot major changes in market trends as they emerge. And by spotting those changes, you can position yourself to capture solid profits in a new market uptrend and keep the bulk of those gains when the market eventually enters a downturn.

E (Very Weak) - The stock has significantly underperformed most other funds given the level of risk in its underlying investments, resulting in a very weak risk-adjusted performance. Thus, its investment strategy and/or management has done just the opposite of what was needed to maximize returns in the recent economic environment. While the risk-adjusted performance of any stock is subject to change, we believe this fund has proven to be a very bad investment in the recent past. 

When thinking about the mindset of investors, The Great Crash 1929 by J.K.Galbraith (reviewed here) should also be required reading. Typically, any sustained fall in prices - known as a bear market - is very destructive to wealth. However, as Galbraith explains wonderfully, each bear market is unique and is a reflection of the bull market that came before it. The book explains a great deal about the feedback loops that can exist when prices rise and fall as more people are either sucked into or forced out of holdings. It is the reference work about a very important slice of Wall Street history.
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. If you plan to invest in growth stocks, it would be wise to read about technology and the latest trends. Perhaps you could subscribe to one or more trade publications that relate to the sector(s) that you are most interested in.
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.
Intuitive Surgical (NASDAQ:ISRG) -- Intuitive Surgical is a healthcare company that makes surgical robots and is the clear leader in the space. There are tens of thousands of doctors trained on the company's da Vinci surgical robots and more than 4,400 of the robots installed worldwide. As more surgical applications are found for the technology, these machines become more valuable to the hospitals that own and use them.

We all know someone who has “tried” investing in the stock market, lost a lot of money, and denounced it as a scam. The truth is that the stock market is not a scam; it is an incredible wealth-building tool. Most people who lose money in stocks do so because they get spooked by a dip in the market and then panic. Fearing that they will lose all of their investment, they hastily sell their shares, often at a loss. This should not be the case. Investors must keep in mind that over the long run, the stock market tends to increase in value, so they should think twice before selling their investments in a panic.
It can be helpful to start with paper trading, or simulated trading that allows you to practice without risking actual money. By keeping track of pretend money, and making imaginary trades, you'll learn what tactics work and what sorts of penny stocks provide you with the greatest profits. If you lose on your trades, you don't lose cash in real life, and ideally, you'll learn some things that you might be doing wrong.
Sector leader -- Most of the best starter stocks are either the leader in their respective businesses or very close to it. (You will note this later on in this article when we give some good beginner-friendly stock examples. There's a time and place to invest in up-and-coming companies, but it's smart to save those for after you've learned the ropes.)
