For most investors, the biggest determinant of long-term outcomes isn’t finding the next multi-bagger – it’s avoiding the handful of stocks that permanently destroy capital. 

The data is unambiguous. In his landmark study Do Stocks Outperform Treasury Bills?, Professor Hendrik Bessembinder found that just 4% of listed US stocks accounted for all net wealth creation above Treasury bills since 1926, while the majority failed to outperform cash at all. 

For investors, that means the damage done by owning the wrong stocks can outweigh the benefit of trying to pick the next big winner. In other words, losses are concentrated, and so are mistakes.

That asymmetry matters even more for sophisticated portfolios, where capital preservation and compounding matter as much as upside capture. Avoiding the wrong stocks can quietly do more for returns than chasing the right ones.

With that in mind, we asked ten of Australia’s sharpest investment minds, spanning ASX and global equities, to nominate their stocks to avoid for 2026 and beyond.
