Investors seem to be cashing in on the gains that closed last week. We have red arrows across the three major indices (^DJI, ^GSPC, ^IXIC). Also weighing on equities are the latest talks in Europe on a possible Greek default, certainly worth keeping an eye on.

Here are some of the other stories Yahoo Finance is keeping an eye on today.

U.S. cash abroad
If you believe in "following the money" then you'll find it in U.S. tech companies.  Moody's Investors Service finds five well-known Silicon Valley firms are holding $430 billion dollars in cash reserves. They are: Oracle (ORCL) at $44.7 billion, Cisco Systems (CSCO) with $53 billion, Google (GOOGL) at $64.4 billion, Microsoft (MSFT) with $90.2 billion... and the clear winner, Apple (AAPL) at a whopping $178 billion. And for all five, most of the money is being held overseas.

Saudi snub
The Beltway is buzzing about the king of Saudi Arabia backing out of a planned trip to Washington, D.C.; a protest of the talks between the Obama administration and Iran. What does this signal about the U.S. / Saudi relationship and could it spell more trouble for the Middle East?

Healthy coffee
Frappuccino drinkers are getting more options. Starbucks (SBUX) says in response to customer demand, it is now offering a Mini-Frappuccino.  It's ten ounces as opposed to the "tall" 12 ounce version. Is this a move to appear more health conscious?

Television crossroads
This week is the beginning of "upfronts," when TV networks sell airtime for their upcoming programming to advertisers. And already we've had a bombshell... Fox (FOXA) announcing American Idol, one of the most-successful reality shows ever, is ending after the 2016 season. What else might we learn this week as online adds pressure to old guard content providers.
