At the start of my career, I had the privilege of working for Bryan Hopkins at Old Mutual Asset Management
Bryan was a former Accounting Professor and he taught me a trick that I use regularly
He said, “always look at cumulative cash flow over a number of periods because
2/ cash flow in any one discrete period can be misleading. Cumulative cash flow is closer to the truth”
He’s right
From time to time, I see fund managers referring to a company’s high free cash flow yield over 1 year, but sometimes it’s due to falling inventory as working
3/ capital unwinds from years of inventory build
Except, you can’t unwind inventory forever so using the 1-year number is misleading
Cumulative cash flow offsetting this unwind against the inventory build from prior yrs is closer to the truth
