A stock chart shows historic prices. It is useful when you can decipher what it's showing so you can make more accurate predictions.

1. Identify the trend line
2. Look for lines of support and resistance
3. Know when dividends and stock splits occur
4. Understand historic trading volumes.

It is essential to understand that stocks will take massive dives and make huge climbs. But it is best not to react to these huge drops or gains.

News will come and go, but pay attention to it when news coincides with a drastic change in the trend line. For example, in 2011, Steve Jobs resigned, and Apple noticed that their profit margins were decreasing despite a growing smartphone market. This and other factors caused the stock price to fall. But new CEO Tim Cook turned that around, as noted on the trend line.

While most companies will bounce back, not all can.

Lines of support and resistance are levels at which the stock stays within over a certain period.

• A level of support is a price that a stock is unlikely to drop below.
• A level of resistance is one that it's unlikely to climb above.

The lines are subjective. Everyone will draw these lines differently, depending on how long they plan to hold the stock. Someone planning to hold stock for a long time won't care as much about the ups and downs, but a short-term investor may draw more lines to analyse trends during a shorter period.

You can see at the bottom of the chart when a company issued a dividend and if there was a stock split.

• A dividend is when the company decides to give a portion of its earnings back to its shareholders. (Not all do. Some prefer to focus on growth). If you own the stock, you'll get some of the profit.
• A stock split is when more shares of stock are issued to the public. This is done to attract smaller investors or if the price isn't in line with competitors. For example, Apple did a 7:1 stock split, meaning you now have seven for every share you owned before the split.

At the bottom of the chart are small, vertical lines. This is a trend of the volumes at which the stock is traded.

You should not only focus on volumes when you buy a stock. While there's not always a correlation, sometimes volumes can increase to shift the stock's price quickly.

For example:

• In line A, there was a high volume of trading activity and a drop in the stock price. It could have been news that caused people to panic.
• In line B, there is a slight uptick in trading volume that corresponds to an upward stock price trend. 

When you are practised at reading a stock chart, you might be looking for more powerful tools, such as:

• E*trade takes advantage of robust stock charts and trading tools. However, their pricing isn't the best.
• Robinhood. This app gives just enough information to make informed decisions.
• TD Ameritrade. You pay nothing for access to any of TD Ameritrade's trading platforms, streaming news, and expert research.
• Public makes stock trading into a social event. You have access to a community of investors. Public also gives you access to stocks for as little as $5 and offer fractional shares.
