Finding the Right P/E Multiple – Or How to Handicap a Stock
First, a huge warning about the tables I’ll be showing you in this memo. The P/E multiples shown here are useful as a theoretical tool for getting some idea of how important durability – being able to know a stock will still be turning an annual profit more than 5 years from now – and growth (being able to know a stock will compound intrinsic value faster than the overall market) is in finding the right P/E for a stock.
Basically, what I’m saying here is that if literally all you know about a business is that it will grow 5% a year for the next 5 years (and then you don’t even know if it will lose money or not in year six) – you can’t afford to pay anything but an incredibly low P/E for that stock. Likewise, to justify a P/E ratio of 30 or 100 or some number as unusually high as that – you will need to be able to project a stock will not just compound intrinsic value quickly – but that it will continue to compound at above market rates for 15 to 20 years (not just 5 to 10).
As you read this memo, remember those two principles. And remember this is not a magic formula table that tells you – based on past figures – whether a stock is mispriced or not. It’s a thinking tool that tells you if you really are unusually certain about a stock’s long-term compound future, just how much that certainty should change the P/E you’re willing to pay.
For example, it tells you that you really can pay an absurdly high P/E ratio for a stock you are 100% certain will compound value faster than the S&P 500 – if and only if you know that compounding will last for 15-20 years. Knowing that above average growth will last for 5 years isn’t enough.
Now, to today’s question:
“Would be keen to get your thoughts on how you think about what multiple a stock should trade on and also how you appraise a stock’s value. I think multiple is a function of a number of things – earnings growth, durability, industry evolution, reinvestment and earnings retention etc. – but very keen to hear how you think of it. It’s something that I find difficult, particularly for higher quality businesses that are already on high multiples.”
The formula that really matters in investing is simply:
Compounding Power / Price
If you take “compounding power” and you divide by “price” – you should always know which investment to make. If two stocks have the same price, you should always buy the stock that compounds better. And, if two stocks are equal compounders, you should always buy the cheaper stock.
Warren Buffett’s business partner, Charlie Munger, has said:
“To us, investing is the equivalent of going out and betting against the pari-mutuel system. We look for a horse with one chance in two of winning, and that pays …
