The DVM is a combination of three scores - Durability, Valuation, and Momentum. Each score represents a different part of a stock's performance and helps you evaluate the suitability of a stock for your portfolio. 

A high DVM score indicates that the stock is more promising. A stock can have a DVM score of 0-100. You can use prebuilt screeners to identify High DVM, Mid DVM, and Low DVM stocks. You can also track these to identify stocks entering or exiting the screeners.

The DVM score also helps identify best-performing stocks while avoiding those that perform poorly. This is what each component of the DVM score indicates: 

Durability score is based on the company’s financials, growth, performance, and management performance. A high score indicates consistently high financial performance in terms of revenue, cash flows, and low debt.

Valuation score evaluates whether a stock is overvalued or undervalued based on its current price and price-to-earnings (P/E) ratio.

Momentum score measures the stock's market sentiment and technical indicators. Stocks with high momentum scores are likely to see increased volume, improving sentiment, and better prices.

DVM scores are updated automatically at least once a day at the end of the day. 

The Durability and Valuation scores are updated intraday as new data, such as results, shareholding changes, or insider trades, becomes available. The Momentum score is updated at the end of the day.
