NEW YORK (Reuters) - U.S. stock index futures edged higher on Friday, with major indexes on track for a week of strong gains, though geopolitical concerns remained in view as the tenuous situation in Ukraine continued.
The biggest East-West confrontation since the Cold War ramped up after U.S. President Barack Obama targeted some of Russian President Vladimir Putin's closest long-time political and business allies in response to Russia's seizure of Crimea from Ukraine. Russia retaliated with sanctions of its own against top U.S. politicians.
With the S&P 500 <.SPX> within 1 percent of record levels, some analysts say equities are vulnerable to any fallout from escalating geopolitical tensions, even though few U.S. companies have substantial exposure to the region.

S&P 500 futures rose 4.6 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures rose 36 points and Nasdaq 100 futures rose 9.5 points.
For the week, the Dow <.DJI>, S&P and Nasdaq <.IXIC> are all up 1.7 percent.
Despite the recent strength, volume has been anemic on positive market days, suggesting limited conviction behind the move.

Credit Suisse estimates $14 billion in gross trading will stem from the S&P 500 index rebalance, with another $6 billion coming from rebalancing in other indexes.
