US stocks are on shaky ground today, wavering as investors watch Europe. The situation in Greece has yet to be resolved, and investors are concerned about the outcome.

In the US, though, things aren't looking so bad. Earnings news has been fairly positive, resulting in solid gains for a number of stocks. While some, like Western Union, have proved disappointing, other stocks, like Buffalo Wild Wings, have beat expectations and set new price targets.

For now, though, the news is mostly good. If investors can get over the jitters caused by the European markets, and the situation in Greece, US stock indices are in a fairly good position. 

Global stock indices are mostly lower today, thanks to the latest news about Greece. Concerns about what will happen next in the Greek debt drama has many wondering about the the fate of the global financial situation.

This uncertainty is weighing on global stocks, and many of them are dropping. Indeed, European stocks are mostly lower, with the FTSE 100, IBEX and CAC 40 all down. (The DAX is higher, though.) In the United States, stocks are down in early trading, with the Dow, S&P 500, and Nasdaq all lower.

The Greek debt situation still has not been resolved, and that has many people worried about what could be next. As a result, the riskier assets are not in favour today. Instead, investors are looking for safe havens, and that means stocks are headed lower.
