$RENT is a timely example of point #3: Stock up 25% in the morning on a strong beat in 4Q, little analyst coverage. The stock now is down 15%, that is a 40% move. I shorted a bit more at some point today when it was still up 10% or so. The fundamentals, the quality of its revenue growth is worsening and outlook is bad. The company needs to spend a significant amount on inventory, a hidden cost not on the income statement but rather depreciates through COGS overtime instead and is not even visible in any given quarter as a large loss. If they don't replenish inventory, customer satisfaction will likely deteriorate. They are planning to spend less on inventory and yet they are still guiding to margin deterioration in 2026.
