Before we let you go, here are three investing mistakes you probably continue to make. Consider them carefully and then try not to make them again. 

Mistake #1. Putting Full Faith in Management

Management has one over-arching goal: talk about the awesomeness of the company today and it's potential for awesomeness in the future. In short, stay skeptical of even the best-performing management teams to avoid being surprised come earnings season. Let the numbers dictate your actions, but always question the reasoning of the folks in charge earning the big paychecks. 

Mistake #2: Thinking a Company Has No Competitors

It's easy to think Amazon (AMZN) is on a planet of its own. The mere mention of the company getting into a new space often sends shock-waves through the stock prices of long-time players in that sector. Hence, it's easy to fall into the trap that an Amazon -- or others like it -- will blow rivals away and post mind-boggling quarterly profits for as far as the eye could see. 

That's not the case. All companies, even the mighty ones, have hungry competitors that are likely doing things to steal business. For example, Walmart (WMT) has done top work to remodel its stores and overhaul its online presence to challenge Amazon. 

Respect the competition in your assessment of a company. 

Mistake #3. Being Obsessed With Stock Buybacks

At the very core, stock buybacks are designed to do one thing only. That is pump up a stock price by reducing the number of shares outstanding. The reason to do this stem from executives having a desire to make a quarter look better than it was or to juice earnings and hit an annual bonus target. Many times annual bonuses for executives are tied to earnings per share performance, which could be manipulated by stock buybacks. 

Don't make the mistake of thinking stock buyback announcements are the holy grail. They aren't. In fact, they could be viewed as a red flag that the profit potential of a business is nearing a short-term top.
