Free Cashflow Yield

I've been a long-time lurker on Quantopian but have only recently managed to get a grasp of the platform and put some backtests together.
Having finally figured out how to use the fundamental data and alphalens I've put together a very simple but alarmingly effective strategy based on Free Cash Flow yield. Interestingly it works very well until the start of this year - would be keen to hear thoughts. I suspect a lot of quality-based factor strategies are underperforming this year as we enter into these later stages of the bull market in equities.

Below a brief outline of the strategy - interested to hear thought/criticisms. Open to the possibility that I've made a fatal error somewhere.
1) Rank Q1500 universe by Free Cash Flow Yield
2) Long top Quintile, Short Bottom Quintile
3) Rebalance weekly

Thank you for sharing.

This is exactly the type of thing that is great for Thursday's webinar. I ran a tear sheet for you. If you send that to [email protected], and register for the webinar, you can get a live analysis of your algo from our Managing Director of Research, Dr. Jess Stauth. I think she'd be able to tell you a lot.

Thanks Dan, will do.

Yup I have been doing alot of testing on free cash flow yield too. But with the use of seasonality investing, monthly rebalancing. Performs very well!

Completely agree, and this is one of my favorite numbers. The financial press loves to focus on Earnings (EPS, PE ratio, etc), but in fact there is sufficient scope within generally accepted accounting practices (GAAP) for companies to do a lot of sometimes less-than-completely-honest manipulating of their "Earnings", e.g. by changing depreciation methods, etc. Earnings is just an accounting number, but cash is cash, and there is a lot less scope for manipulating cash flow data.

Focusing on cash flow is a good idea. Even more instructive is what you can find if you start comparing earnings & cash-flow and the various component numbers related to each of them. In addition to making a useful valuation metric, it is also a good way to spot accounting fraud (e.g. Enron). See also Pietroski score item #4: Cash flow from operations > Net Income. Reference


Is this the kind of algorithm that you would consider for allocation, and if not, what are its deficiencies that one can learn from in this regard? Is it the exposure to different factors, or something else, perhaps?

Many thanks in advance.

Tim - I don't mean to be coy, but Jess is going to be able to answer that better than I can. I think you will enjoy the webinar tomorrow for that reason.
