At the age of 82, Dorothy, a retired lawyer from Winnipeg, has managed to build up a tax-free savings account (TFSA) worth over $600,000. Her strategy? A simple yet effective one – she buys what she knows. This approach, coupled with her astute financial management, has led to the impressive growth of her portfolio, despite her low-key involvement in it.

Investment Strategy: Follow What You Know

Initially, Dorothy mirrored the holdings of mutual funds like the RBC Canadian Dividend Fund. To maximize returns, she reinvested dividends automatically through an online brokerage account. However, a shift in her investment strategy came when she decided to buy shares in companies whose products she enjoyed using. This ‘buy what you know’ approach was famously employed by Peter Lynch, the former manager of the Fidelity Magellan Fund.

Dorothy’s investment decisions were informed by her own experiences and the tech innovations of recent decades like smartphones, internet search engines, word processors, and online shopping. She invested in tech giants like Apple Inc., Alphabet Inc., Microsoft Corp., and Amazon.com Inc. Though these were not substantial purchases, her strategy of holding onto these stocks allowed for substantial capital gains over time.

Portfolio Management: Minimal Involvement, Maximum Gains

Despite the significant growth of her TFSA, Dorothy spends little time managing her portfolio. She estimates that she only spends between 12 to 15 hours a year on her portfolio. This minimal involvement has not only saved her time but also spared her from the stress of the short-term volatility of stocks.

Her investment philosophy is simple – avoid companies she doesn’t understand and those that are unprofitable. This is why, despite its popularity, she chose not to invest in Tesla Inc. Furthermore, she relies on Gordon Pape’s Income Investor newsletter for insights on which income stocks to buy or sell in her registered retirement income fund (RRIF).

Expert Perspective on Dorothy’s TFSA

Nancy Woods, a senior portfolio manager and investment adviser with RBC Dominion Securities Inc., has praised Dorothy’s impressive returns. However, she also noted that Dorothy’s heavy concentration in the tech sector increases her risk, especially given the high valuations of tech stocks. Woods suggests that Dorothy might consider rebalancing her portfolio to diversify her investments and reduce her overall risk.

Woods also recommended that Dorothy consider drawing up an estate plan for her TFSA. As she does not anticipate needing to withdraw funds from it, and since she does not have a successor annuitant, it would be prudent to plan for the eventual transfer of these assets to her children.

Dorothy’s story is a testament to the effectiveness of a simple, intuitive investment strategy. Despite her minimal involvement, her ‘buy what you know’ approach has yielded impressive results, demonstrating that one does not need to be a financial expert to build a substantial portfolio.
