INVESTOR LETTER #136
Tracking Your Portfolio
Investing doesn't end after you buy a stock. Great investors regularly track their portfolio—not to watch prices every minute, but to monitor whether the businesses they own are performing as expected. The goal is to follow the progress of the company, not the daily movement of its share price.
INVESTOR NOTE
A business owner thinks in decades. A speculator thinks in minutes.
Buying Is Only the Beginning
Imagine buying a fruit tree and never checking on it again. You wouldn't know whether it was growing, needed water, or had become diseased. Stocks are no different. Once you become a shareholder, you should continue following the business.
What Does It Mean to Track a Portfolio?
Tracking your portfolio means regularly reviewing the businesses you own, their financial performance, important news, valuations, and whether your original investment thesis is still valid.
Don't Confuse Tracking With Watching Prices
Many beginners open their portfolio app several times a day to see whether prices are green or red. That's monitoring the market, not tracking your investments. Businesses create wealth through years of execution, not daily price changes.
Focus on Business Performance
Pay attention to quarterly results, annual reports, earnings calls, management commentary, new products, customer growth, profitability, and cash flow. These tell you far more about your investment than today's stock price.
Review Your Investment Thesis
Every few months, revisit the reasons you bought each company. Ask yourself whether the business is progressing as expected or whether something important has changed.
Separate Noise From Important News
Markets generate thousands of headlines every day. Most have little long-term impact. Learn to distinguish temporary market noise from developments that genuinely affect the company's future.
Keep Simple Records
Maintain a record of when you bought a company, why you invested, your estimated intrinsic value, and any major developments over time. Looking back at your own notes often teaches more than looking at the share price.
Learn From Every Investment
Both successful and unsuccessful investments provide valuable lessons. Reviewing your portfolio regularly helps you recognize patterns in your decision-making and become a better investor over time.
Avoid Obsessing Over Daily Returns
Checking your portfolio every hour rarely improves investment decisions. In fact, it often increases emotional reactions. Great investors focus on long-term business performance rather than short-term market fluctuations.
A Portfolio Reflects Your Thinking
Your portfolio is a collection of your best investment ideas. As your knowledge improves, your portfolio should evolve too. Tracking helps ensure that every company you own still deserves its place.
Own Businesses, Not Tickers
The best investors don't wake up wondering whether their stocks went up today. They ask whether the businesses they own are becoming stronger. If the answer is yes, temporary price movements matter very little. Track the business, trust the process, and let time do the heavy lifting.
