In consumer marketing, there is a concept called “renting share” with which every assistant product manager is familiar. When a company puts a temporary price promotion on a product (e.g. potato chips, sneakers, furniture), the company will see an increase in purchases pulled forward from future periods as would-be consumers try to lock in the temporary discounted price. When the current and future periods are netted together, one tends to see no change in sales unless there is a permanent change in perception of the product. All evidence so far suggests this will be true of $Tesla(TSLA.US) ‘s 10-day promotion of Cybertruck after which TSLA will likely raise the price. Once the promotion is over, the heightened interest goes back to normal.
