They draw a box around the recent highs and lows to have a fair idea about an entry point and an exit point for the stop-loss order. Stock is considered in the box only when the price outpaces the previous high but then falls back to a price that is somewhat close to the previous high.
After reading the above content, it’s fair to assume that Darvas’s box theory is best suited to a rising market. Darvas box theory follows momentum strategy as it uses both, market momentum theory and technical analysis, to determine valid entry and exit points.
Precisely, Darvas box theory mainly focuses on buying companies having promising growth and earnings prospects. They should belong to the solid industry group. Overall trends in the market should be assessed, like stocks, in general, should be in an uptrend and breakout should be supported by higher volumes.
Darvas box theory is not time-bound and can be used at any time period. In the real world, this theory helps investors in having performance that outpaces overall market performance.
The theory is entirely based on tracking industry-wide growth through the performance of selected stocks, their prices, and trends in trading over time.

Assessing and tracking certain stocks, principally high-volume stocks, helps investors check implied strong moves by the underlying securities and when can they be entered or exited.
Market technicians using Darvas box theory are required to select certain stocks and evaluate their trends in prices. Traders then should see volume as a significant indication of an expected move.
Nicolas Darvas encouraged investors to rely only on those stocks which have high volumes. This was because he believed that high volumes signify a stock with strong moves. Now, the question arises that why this strategy was successful.
In the earlier days, trading was not easy as it is today. Earlier, going long on high-quality, dividend-paying stocks was followed by most of the investors as there were mostly long-term investors. Investors used to choose dividend income as opposed to capital appreciation.
Later, Nicolas Darvas introduced this box theory to the market, giving no consideration to dividends whatsoever, and he clearly explained stop-loss points.
Though market technicians follow Darvas’s theory, it does have a small fundamental attribute attached to it. Darvas’s theory focuses on the industries which can perform well over the upcoming 10-20 years. Basically, the selection of stocks is based on the industries having solid growth potential.
How Nicolas Darvas Used This Box Theory?
After identifying a developed industry, Nicolas Darvas used to create a list of stocks. Due to the commission structure, he only focused on stocks that are highly-priced. As there were fixed commissions, the cost of trading, on a per-share basis, fell significantly when stock prices increased.
While a buy-and-hold investor would not pay much heed to this, Darvas came to a conclusion that a significant part of the profits can go to commissions if this is not followed.
Darvas looked for a sign, and the only indicator he used was trading volume. He used to look for heavy volume, and when he spotted an unusual volume, he immediately used to contact his broker.

What Critics Have to Say About Darvas Box Theory?
While there are advantages of using Nicolas Darvas Box Theory, there are some limitations too. Critics of Darvas Box theory attribute much of the success of Nicolas Darvas to the fact that he used to put trades when the overall market was in an uptrend. Critics believed that this strategy fails when the overall market falls.
If the trend doesn’t get developed as expected, investors can end up making losses. Some critics also argued that some trends in the market cannot be predicted, and in such cases, this theory loses its value.
