In contrast to finding an expert or two that seems to make valuable and careful decisions, do your best to avoid listening to share market 'tips' from friends or work colleagues. Typically these people will know less than you and have very little to base their suggestion on. No matter how well meaning it may be, advice from someone who knows next to nothing about the topic in question is not advice.
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.
You're probably looking for deals and low prices, but stay away from penny stocks. These stocks are often illiquid, and chances of hitting a jackpot are often bleak. Many stocks trading under $5 a share become de-listed from major stock exchanges and are only tradable over-the-counter (OTC). Unless you see a real opportunity and have done your research, stay clear of these.
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.
And you can find such stocks in lists like the IBD 50, Sector Leaders, IBD Big Cap 20 and IPO Leaders. For example, fast-growing semiconductor designer and artificial intelligence (AI) stock Nvidia was featured on the IBD 50 before it surged 750%. And Apple has been featured on various IBD lists as it has made big moves in recent years. While, of course, not every stock featured on an IBD list will make the type of moves that Nvidia and Apple have made, it does show why it pays to regularly update your list of stocks to watch using these S&P 500-beating screens.
Most of these services offer some form of free portfolio tracking - this enables you to create a portfolio and track it properly to see how you do with no money on the line. This used to be known as paper trading in the 'good old days' before 2001. This kind of exercise can be a good way to learn and play around with things without being either serious or costly.
Dollar-cost average: This sounds complicated, but it’s not. Dollar-cost averaging means investing a set amount of money at regular intervals, such as once per week or month. That set amount buys more shares when the stock price goes down and fewer shares when it rises, but overall, it evens out the average price you pay. Some online brokerage firms let investors set up an automated investing schedule.
