In shorting stocks, it’s far better to short a company with deteriorating fundamentals than a rich valuation. Deteriorating fundamentals mean a bad business model where volumes are declining, or there’s no innovation, or management can’t execute, or there’s a loss in pricing power because of excess competition and a lack of differentiated products.
In my experience there are too many PMs and analysts in the industry with mainly financial backgrounds who pay little or no attention to fundamentals and rely instead on valuations and short term estimate trends to develop short ideas rather than try to determine whether a company with a hot new product can turn around stagnating comps when rising comps are what drives the stock. Over and over again, getting a company’s fundamentals right beats valuation insight.We would not short $Tesla(TSLA.US) even though its base business (EVs) seems to be deteriorating (2026 will be third consecutive down year for deliveries) while the overall EV industry is growing at 20-25% per year in units. TSLA mgmt’s strategy to use zero interest rate and promotional incentives instead of communicating its competitive advantages directly to consumers is clearly not working but with generalized unsupervised autonomy technology about to transform the industry, TSLA is likely to offset declines in its base EV business with new autonomous revenue streams. While TSLA’s 2026 P/E of 210x seems way extended vs +35% long-term earnings growth, we would not short TSLA stock on what are largely valuation grounds.The copyright of this article belongs to the original author/organization.
