Welcome to Claman on Call -- the markets may be closed, but FOX Business is always on call.

Facebook (FB) experienced a brief outage on Wednesday during the last hour of trading. Users reported the social network went down on the web and on mobile devices for about twenty minutes. TechCrunch reported the short outage could have cost the social media giant as much as half a million dollars. That had no impact on Facebook shares, though. And the stock hit a new 52-week high earlier in the day.

Another tech titan, Apple (AAPL), was a big loser on the Nasdaq on Wednesday. After hitting a fresh 52-week high on Tuesday, Apple tumbled more than 4%, erasing $26 billion from its market cap. All this ahead of the company's big product unveil next Tuesday. Plus, rival Samsung earlier in the day showed off a brand new smartphone with a curved edge, and also a virtual reality headset.

Can Apple take back the headlines and outshine Samsung with its latest generation iPhone 6 next week? FOX Business will continue to watch this story for you.

And the string of corporate cyber attacks continues, with Home Depot (HD) being the latest potential high-profile victim. The home improvement store is still dealing with investor fallout following reports of a possible data breach earlier in the week, and the stock ended the day with a loss of more than 2%.

Former Home Depot chairman and CEO Bob Nardelli told FOX Business in an exclusive interview that the retailer's cyber security has come a long way since he was CEO, but it still has to keep improving.

Did you know that Home Depot is doing 1.2 billion transactions a year. For more fascinating facts about the retailer, check out FOX Business's full interview with Nardelli at FOXBusiness.com/oncall.

And in other hacking news, CrowdStrike co-founder and CEO George Kurtz told FOX Business in an exclusive interview how you, the investor, can spot companies at risk of cyber hack -- before you buy the stock.
