Kratos was awarded a valuable contract to lead a team integrating existing and next-generation ground assets supporting the Resilient Missile Warning and Tracking (MWT) program for the U.S. Space Force. That's undoubtedly good for the company and will boost its already rapid business expansion. But investors have already built a lot of good news into Kratos' valuation. Even after the stock has dropped more than 20% over the last month, shares still trade at a premium valuation. A price-to-sales (P/S) ratio of about 8 means investors expect more large contracts to be announced. In the meantime, some opted to sell on the news and perhaps allocate those funds elsewhere. A strong underlying business means this name could be a great stock to own. That time just isn't quite yet, as the stock continues to consolidate to a more reasonable valuation. <h2>Should you buy stock in Kratos Defense &amp; Security Solutions right now?</h2> Before you buy stock in Kratos Defense &amp; Security Solutions, consider this: The Motley Fool Stock Advisor analyst team just identified what they believe are the 10 best stocks for investors to buy now… and Kratos Defense &amp; Security Solutions wasn’t one of them.

Kratos Defense & Security Solutions (NASDAQ: KTOS) stock fell 7.8% despite securing a significant contract worth up to $446.8 million from the U.S. Space Force for missile warning system operations. The decline is attributed to a "sell the news" mentality, as investors react to the stock's high valuation, with a price-to-sales ratio of about 8. Although the contract is expected to enhance the company's growth, many investors are reallocating their funds, leading to the stock's drop.
