Risk: A good way to gauge risk for WDC is to check how deeply it fell during major market shocks. It plunged nearly 90% in the Dot-Com crash, took a 75% hit in the Global Financial Crisis, and dropped around 61% during the inflation shock. Even the less severe events like the 2018 correction and the Covid pandemic led to dips of about 66% and 59%, respectively. Solid fundamentals matter, but when panic hits, WDC hasn’t been immune to steep losses.
WDC 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.
