As the Nasdaq Composite continues to trend downward, more and more Wall Street analysts have the word "correction" on their lips. The index has been pulled down largely by social media and biotech stocks, but companies across technology have been feeling the burn.

On Tuesday's edition of Investor Beat, host Alison Southwick and Motley Fool analysts Morgan Housel and Mike Olsen discuss this major pullback. Morgan gives his thoughts on market corrections in general and how often investors can expect to see this kind of downward fall, while Mike looks at the actual value of the market today.

Then the guys look at four stocks making moves on the market today. Google has just acquired Titan Aerospace, a maker of solar-powered drones. The search giant has said it could use the technology both for collecting high-resolution images, and for offering Internet access in remote areas. Coca-Cola stock was up today, after the company beat analysts' expectations for first-quarter earnings. However, revenue was still down 4% for the quarter, amid declining consumer demand for soft drinks. Motorola has now sold off its enterprise business, which makes hardware such as computers, tablets, and barcode scanners, to a barcode printer maker called Zebra Technologies. And Citigroup saw shares rise after beating the rather low expectations for its first quarter.

And finally, Mike and Morgan each discuss one stock popping up on their radar this week. Mike looks at the curiosity that is Amazon.com, the behemoth that defies all prediction of how big it can one day get. Meanwhile, Morgan points out that at just around 1.3 times book value, Berkshire Hathaway is one of the last places investors can go for value on the market today.
