Progressive grows auto book in February but underwriting margin slips

For now, Progressive’s ability to grow policies in force at double‑digit rates while holding its combined ratio in the mid‑80s reinforces its position as one of the more profitable large US personal lines writers on a run‑rate basis. The higher combined ratio, however, indicates that even the sector’s better‑positioned carriers are not insulated from volatility in frequency and severity, and that further detail on loss trends, weather, and large‑loss experience will be key when Progressive releases its broader quarterly results.
