Washington H. Soul Pattinson's key holding, Brickworks, reported a four-year statutory loss of $119 million, primarily due to challenges in its building products division and property asset devaluations. Despite these setbacks, rising rents in its industrial properties present a potential growth area, suggesting a cautious hold for investors.Brickworks is currently under-rented by about 40%, and addressing this gap could lead to significant future gains. Investors are advised to hold these stocks for stable returns, particularly during market volatility, as they offer a resilient addition to a long-term portfolio.
