Discuss the importance of regular portfolio review and the factors that might signal a need to rebalance.

Summary: How to Avoid Surprises in a Two-Stock Portfolio by Reviewing and Rebalancing If you’ve ever felt blindsided by sudden losses or wild swings in your two-stock portfolio, you’re not alone. Many investors—even those who only own two stocks—are surprised by how quickly their asset allocation can drift off course. In this article, I’ll share practical tips, industry insights, and even a few personal missteps that can help you decide how often to review and rebalance, avoid nasty surprises, and keep your investments aligned with your goals. There’s no single right answer, but by the end, you’ll have a framework that fits your real life, not just a textbook. Why Regular Review and Rebalancing Actually Matter Let’s be honest: it’s tempting to “set and forget” your portfolio. But even with just two stocks, things change fast. I learned this the hard way in 2022 when I held equal parts of a tech giant and a consumer staples company. Six months later, tech soared and suddenly made up 70% of my portfolio, totally skewing my risk. I wish I’d checked in sooner. According to Vanguard’s rebalancing research, portfolios can drift significantly within even a single quarter due to market volatility.
