Graham recommended three categories of stocks — Defensive, Enterprising, and NCAV (or Net-Net). He also specified 17 rules to identify such stocks; based on qualitative factors such as growth and stability, as well as quantitative factors such as earnings and assets.

Serenity's algorithms evaluate 5000+ U.S. stocks against all 17 Graham rules, adjusting only for inflation. Serenity's screeners then let you compare all 5000+ stocks against each other, helping you make well-informed investment decisions.

Why Graham?

"My intellectual odyssey ended, however, when I met Ben and Dave, first through their writings and then in person. They laid out a roadmap for investing that I have now been following for 57 years. There’s been no reason to look for another."
Warren Buffett, in his 2008 foreword to Graham's book Security Analysis (Dave Dodd was Graham's co-author).
"The real secret to investing is that there is no secret to investing. Every important aspect of value investing has been made available to the public many times over, beginning in 1934 with the first edition of Security Analysis."
Seth Klarman, in his 2008 preface to Graham's book Security Analysis.
"There will continue to be wide discrepancies between price and value in the marketplace, and those who read their Graham & Dodd will continue to prosper."
Warren Buffett, concluding The Superinvestors of Graham-and-Doddsville; a talk given at Columbia University in 1984.

Why Serenity?

1. Authenticity

Serenity focuses on — and specializes in — Graham analysis.


“The key to good decision making is not knowledge. It is understanding. We are swimming in the former. We are desperately lacking in the latter.”
Malcolm Gladwell, Blink: The Power of Thinking Without Thinking

Serenity does a complete 17-rule Graham analysis; and nothing more. This is based on a strong conviction in Graham's framework for understanding stocks, which Buffett and Klarman too so emphatically expressed. The Graham rules used on Serenity are given with references. All data used is publicly verifiable.

2. Accuracy

All analyses done by Serenity are automated, with no room for human error.

While there is no substitute for human judgment, computers excel at repetitive mathematical tasks. Having all the relevant numbers accurately calculated — and presented in a structured manner — can therefore greatly aid an investor in making the right decision.

"Operations for profit should be based not on optimism but on arithmetic."
Benjamin Graham, Chapter 20: “Margin of Safety” as the Central Concept of Investment, The Intelligent Investor

So you won't be seeing any colorful graphics — or story stocks — on Serenity. What you'll see instead, is some very powerful software doing some serious number crunching.

Graham repeatedly emphasized that investors should act like businessmen, and not speculators or gamblers.

"An investment operation is one which, upon thorough analysis promises safety of principal and an adequate return. Operations not meeting these requirements are speculative."
Benjamin Graham, Chapter 1: Investment versus Speculation, The Intelligent Investor
"Rule No.1: Never lose money. Rule No.2: Never forget rule No.1."
Warren Buffett, [Multiple Sources]

"Loss avoidance must be the cornerstone of your investment philosophy."
Seth Klarman, Margin of Safety: Risk-averse Value Investing Strategies for the Thoughtful Investor

"To distill the secret of sound investment into three words, we venture the motto - Margin of Safety."
Benjamin Graham, Chapter 20: “Margin of Safety” as the Central Concept of Investment, The Intelligent Investor

Graham's 17 rules help ensure a measurable Margin of Safety — that is both qualitative and quantitative — in one's investment operations.

Using Serenity to apply Graham's framework ensures that your investment research is thorough, without being tedious.

"there has developed the general notion that the rate of return which the investor should aim for is more or less proportionate to the degree of risk he is ready to run. Our view is different. The rate of return sought should be dependent, rather, on the amount of intelligent effort the investor is willing and able to bring to bear on his task."
Benjamin Graham, Chapter 4: General Portfolio Policy, The Intelligent Investor

Instead of pouring over annual reports and subjective analyses, you can now apply objective investment concepts to large volumes of data and see the results immediately. Your due diligence becomes both faster, and more accurate.

3. Value

There are services out there charging $400 a year for downloading a spreadsheet that lets you analyze one stock at a time. None of these services use the authentic Graham framework. Some even use methods Graham specifically warns against. Serenity, on the other hand, is built to follow Graham's principles as closely as possible; in both letter and spirit.

Warren Buffett famously said in The Superinvestors of Graham-and-Doddsville that "it is hard to argue that the market always prices rationally. In fact, market prices are frequently nonsensical". An investor's most valuable asset is being able to spot — and take advantage of — such discrepancies between price and value; whether in stocks or in technology.
