The last time the Tesla shares were hit this hard was on Jan. 18, also following actions by Musk intended to lower the price of the Model 3. On that day, Musk said 7 percent of Tesla's workforce would be let go.

The base price for the Model 3, Tesla's cheapest car, is now $44,000. Musk believes the mid-$30,000 range is the sweet spot.
