Just when you think the bottom is going to fall out of this market, the bull keeps charging and the indexes push higher. That was the case Friday as geopolitical tensions with North Korea, and another London terrorist attack, set the stage for a day with potential gloom and doom.

Not so much, though, as the Dow Jones Industrial Average, S&P 500 and Nasdaq all ended higher, with the Nasdaq closing at 2,500 for the first time ever. So much for that Friday selloff.

With the markets riding high, it wasn't all positive for corporate America. President Donald Trump's decision to block Canyon Bridge Capital Partners LLP's $1.3 billion plan to acquire Lattice Semiconductor Corp. (LSCC) - Get Report could trip a domino effect of dealmakers calling off pending transactions. Trump's order is among his first actions that may telegraph how cross-border deals might be dealt with under his administration, especially when it comes to national security concerns and China. It could lead to other companies currently in the review process with CFIUS to cancel deals in anticipation they might be blocked.

One cross-border deal that likely won't be turned down would be if Apple Inc.'s (AAPL) - Get Report acquisition of Toshiba's chip business. Though no stranger to helping suppliers foot the bill for new production lines, the company now also seems willing to take stakes in suppliers to further strategic goals. The Cupertino, Calif.-based company is reportedly in talks with Bain Capital LP to chip in about $3 billion in equity to acquire the memory chip business of the failed Japanese chipmaker.

If the Bain-led group manages to win out, it would help Apple secure favorable supplies and pricing from a company estimated to have a near-20% global NAND flash memory share. Apple rebounded nicely on Friday but had been under pressure since Tuesday as investors assessed how its latest product launches, including a $1,000 iPhone.

Sen. Elizabeth Warren (D-MA) on Friday stated that she has launched an investigation into Equifax Inc.'s ( (EFX) - Get Report ) major data breach that compromised the data of 143 million people. The data breach highlights the need for better cybersecurity measures but also highlights America's dependence on credit cards. Though the first credit cards were launched in the 1950s (Diners Club Card 1951, American Express Co. (AXP) - Get Report 1952), the United States didn't get hooked on the credit card business until the '70s and '80s when a host of options (backed by everyone from banks to retailers) began to emerge. Above is a photo from 1979 depicting the various options consumers had for credit cards versus the variations of the good old greenback. As for Equifax, Warren, along with 11 other Democratic senators, are set to introduce a bill that would give customers the ability to freeze their credit for free. Read More.
