The Sales and Assets criteria for company size in the Value Investing framework of Benjamin Graham — Warren Buffett's mentor — are $500 million and $250 million today.
Criteria For Size
Graham's framework states that a stock for Defensive investment should have:
"Not less than $100 million of annual sales... not less than $50 million of total assets for a public utility."
When adjusted for Inflation — or the increase in the Consumer Price Index (CPI) — since the time the above was written in 1971, these figures work out to $500 million and $250 million respectively.
These are the default selection criteria today on Serenity.
The sliders on the Advanced Graham Screener allow further customization of Graham's criteria as well.
a. Size in Sales (100% ⇒ 500 Million)
A value of 100% on the Size in Sales filter implies a Sales value of 500 Million. The filter moves in steps of 5% which corresponds to steps of 25 Million each.
b. Size in Assets (100% ⇒ 250 Million)
Similarly, a value of 100% on the Size in Assets filter implies a Total Assets value of 250 Million. This filter too moves in steps of 5%, which corresponds to steps of 12.50 Million each.
As an example, setting Size in Sales to 140% will show stocks with 700 million or more in Sales (in the listed currency).
