This article appears as part of Casey Weade's Weekend Reading for Retirees series. Every Friday, Casey highlights four hand-picked articles on trending retirement topics and delivers them straight to your email inbox. Get on the list here.

📌 You can get smoked in the short-term: Any investor knows this too well, but it’s maintaining that long-term mindset that helps you stomach the short-term blows.

📌 Don’t ever expect average: You might have heard the stock market yields, on average, 10 percent annually. However, this rarely happens in a given year, and more so applies to the long-term.

📌 Stocks offer asymmetric upside: As stated in the article, “A stock can only go down by 100 percent, but there’s no limit to how many times that value can multiply going up.”

Rest assured: You don’t need to understand all of the intricacies of the stock market, or investing, for that matter. A simple handful of key concepts are often what make the best investors.
