Thor Industries (THO) – Closing Long Position – up 90% vs. S&P up 16%
Thor Industries (THO: $116/share) was featured as a Long Idea on 3/27/19. At the time, Thor Industries received a Very Attractive rating. Our long thesis highlighted the firm’s industry leading profitability, long-term secular demand for RVs, and the stock’s cheap valuation.
This report, along with all of our research[1], utilizes our superior data[2] to get the truth about earnings, as shown in the Harvard Business School and MIT Sloan paper, “Core Earnings: New Data and Evidence.”
During the 492 day holding period, THO outperformed as a long position, rising 90% compared to a 16% gain for the S&P 500.
Thor’s profitability fell in 2019, as inventory and demand returned to more normal levels after a record 2018, and that trend has continued into the trailing-twelve-month (TTM) period. The firm’s return on invested capital (ROIC) has fallen from 17% at the time of our report to 6% TTM.
The deterioration in fundamentals, coupled with a soaring stock price (+60% year-to-date) due to optimism over RV demand during and after the COVID-19 pandemic, means THO no longer presents the same risk/reward. The firm now receives our Very Unattractive rating. We believe it is time to take the gains and close this long position.
