Frequent buying and selling of stocks can trim overall gains, according to veteran investor Saurabh Mukherjea, who popularized the Coffee Can Investing approach. The gist: longer horizons and fewer trades often outperform over time.
What the method promotes
- Invest in high quality, durable businesses and hold for the long term
- Limit transaction costs, taxes, and the risk of emotional trading
- Let the investment thesis drive decisions, not daily price movements
How to decide whether to hold or sell
- Verify that the original reasons for the buy remain intact
- Assess if the stock still offers attractive value or if a better opportunity exists elsewhere
- Consider costs and tax impact of selling versus staying invested
- Weigh the potential gain from waiting against the benefit of redeploying capital
Practical takeaways
- High turnover often hurts compounding and risk-adjusted returns
- Focus on a concentrated, long-term portfolio rather than frequent trading
Analysis
In markets where transaction costs and taxes can erode gains, a bottom-up, buy-and-hold discipline may improve compounding. Mukherjea argues that sticking to a clear investment thesis and avoiding overtrading helps preserve capital and discipline, central tenets of the Coffee Can framework.
