Risk: A good way to understand GOOGL’s risk is by checking its drawdowns during major market shocks. It fell about 65% in the Global Financial Crisis, 44% during the Inflation Shock, and over 30% in the Covid sell-off. Even the 2018 correction wasn’t kind, with a dip of around 23%. So, while GOOGL looks solid on paper, history shows it’s not immune when markets turn south.

GOOGL 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.
