Darvas Box Theory

What it is:

Named after famous ballroom dancer Nicolas Darvas, the Darvas box theory is a trading technique based on 52-week highs and volumes.

How it works (Example):

To implement a Darvas box technique, an investor simply looks at stocks with heavy trading volume and then buys those stocks when they rise above their 52-week highs.

Specifically, the stock's 52-week high represents the floor of the box. When the stock price reaches a new 52-week high and then falls from that high or at least doesn’t penetrate that high for three days, that new 52-week high becomes the top of the box. The idea is simple: when the stock goes above the top of the box, buy the stock; when the stock goes below the floor of the box, sell it.

A new box forms when the stock hits a third 52-week high, with the second 52-week high becoming the floor. In this way, boxes can pile up.

Why it Matters:

The Darvas box technique is easy to use and relies only on stock prices and trading volumes for buy and sell signals. The trick worked for Darvas: he reportedly turned a few thousand dollars into millions in 1956. However, critics argue that the technique produces profits only in bull markets.
