Risk: A good way to gauge risk with Thermo Fisher (TMO) is by checking how much it fell in major market sell-offs. It dropped about 41.5% in the Dot-Com crash and took an even bigger hit of around 54% during the Global Financial Crisis. The 2018 correction wasn’t as steep, but still a notable 17%. Covid led to a roughly 25% drop, and the inflation shock brought a 35% pullback. So even for a solid name like TMO, significant dips happen when markets turn sour. Quality helps, but it doesn’t make the stock immune to big sell-offs.
TMO stock may have seen strong gains recently, but investing in a single stock without detailed, thorough analysis can be risky. The Trefis High Quality (HQ) Portfolio, with a collection of 30 stocks, has a track record of comfortably outperforming its benchmark that includes all 3 — the S&P 500, S&P mid-cap, and Russell 2000 indices. Why is that? As a group, HQ Portfolio stocks provided better returns with less risk versus the benchmark index; less of a roller-coaster ride, as evident in HQ Portfolio performance metrics.
