When it comes to investing, there’s no disputing that having a clearly defined plan in place can help you achieve your investment goals.

Without a plan, it’s easy to get distracted. You can end up trying to time the market, chasing performance and missing out on potential long-term returns.

The Vanguard 2018 Index Chart shows that when it comes to investing, it can be hard to discern a pattern. In any given year, any asset class can finish on top. That’s why the key to achieving their goals is for investors to remain focused on their long-term investment plan rather than short-term market ups and downs.
