$Tesla(TSLA.US) surged again last night, with Q2 total deliveries of 444,000 vehicles exceeding expectations, pushing its market cap back above $730 billion.

Another positive point from this production and sales comparison is that Tesla has begun implementing measures to control production capacity to protect gross margins. Looking at Q2, production dropped to 411,000 vehicles compared to 480,000 in the same period last year. By controlling production capacity, Tesla is trying to reduce inventory, and inventory reduction also means, to some extent, less pressure for future price cuts.

If this production and sales strategy continues, then this year, compared to last year's repeated concerns about the speed of Tesla's gross margin decline, we can focus more simply on vehicle sales.
