This year has forced most of us to accept massive drawdowns in the valuations of our stock portfolios. Although some of these losses have now been reversed, I feel that we’re currently in a holding pattern. Until we see how the COVID-19 pandemic evolves and how much damage has been done to the real economy, it’s hard to know where the market might go next.

There are no new stocks for me to consider in my Stock in Focus (SIF) screen results this week. All five of the companies that qualify for the screen are already in the portfolio: 


Instead, I’ve decided to grasp the thorny topic of how to limit my losses on losing positions in my rules-based SIF portfolio.

  • Personal experience - when I’ve tried to use stop-losses, I’ve usually found that they’re triggered too easily or not soon enough.

  • Although the SIF Folio is a fairly short-term portfolio (typical holding nine months), most of my personal investments are over much longer periods. Selling based on price action alone doesn’t make sense for long-term investments, in my opinion. 

I think that it’s fair to say my…
