A DeepValues app
Is the US stock market cheap or expensive? Two valuation gauges answer it at a glance, every trading day.
On iPhone it is called Buffett Indicator, on Android Bubble Watch: the same app, with the same data.
iPhone: Buffett Indicator, a one-time paid download with no ads. Android: Bubble Watch, free with a small banner ad.
Both ask the same question from different sides: how much are investors paying for US stocks compared with what stands behind them?
It weighs the price of every listed US company against the size of the whole economy. Warren Buffett once called it “probably the best single measure of where valuations stand at any given moment.” Above 100%, stocks are worth more than everything the country produces in a year.
How the app reads it
Averaging ten years of earnings smooths out booms and recessions, so the ratio shows what you pay for a typical decade of profits. It ran famously high before the 1929 crash, the dot-com bubble and 2008.

A DeepValues tab opens DeepValues' value-investing research, for when you want to go from the whole market to single companies.
The total market value of all US stocks divided by US gross domestic product (GDP). It shows how richly the stock market is priced against the economy that earns its profits. The app uses the Wilshire 5000 for market value and official US GDP data.
The S&P 500's price divided by its average inflation-adjusted earnings over the previous ten years, a measure popularized by economist Robert Shiller. Its monthly history goes back to the 1880s.
Both readings refresh once every US trading day. With alerts on, you get a notification when fresh data lands, daily or weekly as you choose.
Bubble Watch on Android is free to download and shows a small banner ad. Buffett Indicator on iPhone is a one-time paid download with no ads and no subscription; the App Store shows the price in your country.
