On Wall Street, a lot of educated monkeys like to talk about valuation expansion. Basically valuation expansion simply means that some stock trading at 15x PE should be trading at 25x PE bcos its industry is sexy, or the company has undergone transformation of its business to become the new growth story or some other cock-and-bull story.

So say the stock price today is $15, and the stock earns an EPS of $1 ie PE is 15x. Valuation expansion simply means that the stock should be $25 bcos PE should be 25x. The basis of this argument is that since the stock is in a growth industry, or has transformed its business, or watever crap reason, the future EPS is not just $1 but much higher. Since we are not sure what that would be, just give it a higher PE to justify this growth.

The ingenuity of this crap theory is that nothing changed, but the “value” of this stock just expanded 60%. This then can be used to justify buying the stock at any price bcos we can always assuming super normal growth and increase the valuation. We can even increase the target multiple further from 25x to 50x. This would expand the original “value” by 333%.

Let’s just do a simple experiment the debunk this valuation expansion theory.

Yr 0 EPS $0.5 (Stock price $25, ie PE 50x)
Yr 1 EPS $1 (Stock price $25, ie PE 25x)
Yr 2 EPS $2
Yr 3 EPS $3
Yr 4 EPS $4
Average EPS $2.1
True intrinsic value (using PE 15x) = $2.1 x 15 = $31.5
Upside = $31.5/$25 = 26%
Upside per yr roughly 5%

Today is Yr 0 and this company started out with an EPS of 50c but bcos of its super power growth, the stock market has already valued it at 50x PE next yr. But it didnt disappoint, its EPS doubled to $1. (Again at today’s price, it’s PE 2 yr out is 25x.) In fact it didnt disappoint for the next 4 yrs and its EPS grew from the initial 50c to $4. This stellar firm actually grew its earnings 8 folds in 5 yrs! Read more…
