So here are some common signs that you aren't ready to be an active investor:
...you can't look at the basic fundamentals such as key statistics, balance sheets, income statements, and cash flow statements.
...you think that risk in the stock market can be measured by price volatility.
...you don't understand the difference between a company's intrinsic value and its stock price.
*please note this is all subjective information, and many investors will define different values of different investing ideas. This can result in many different methodologies, but the facts is better know your stuff and do your own research!
