I work for a Semiconductor distributor. Seeing huge orders from car manufacturers since December. I guess they are stockpiling.
2019 was expected to be a "peak" year in the automotive cycle, so everyone in the supply chain adjusted accordingly by modeling in lower demand following that peak. I'd wager with COVID-19 the trough came significantly faster (and deeper) than anticipated, and as we gear up for an equally fast (expected) recovery, inventory levels aren't adequate.
Just a hypothesis, but perhaps worth considering.
