Stocks surge again; Fed's big gathering; Trump wants to raise taxes... on himself!

Wall Street is on a roll...and the world is following suit. Stocks are higher around the globe following yesterday's massive rally in U.S. equities that ended a nasty 6-day slide. The Dow Jones Industrial Average (^DJI) put in an historic performance, rising 619 points, it's third biggest point gain of all time.

However, Yahoo Finance Senior Columnist Michael Santoli says we really can't tell if the big August selloff is finally over.

"This is a fitful market which is understandable given this volatility shock," he notes. "The market has a lot of work to do--  it has to repair itself for a while. And that's what this back and forth day-to-day trading is basically all about."

Investors are getting a bit of a surprise about the U.S. economy today...the Commerce Department's revised reading of second quarter GDP saw a gain of 3.7%, up from the initial 2.3% estimate and higher than economists had forecast. Santoli believes that news puts the idea of a Fed interest rate hike in September back on the front burner.

Tesla breaks the record books

Now here are some of the stocks the Yahoo Finance team will be watching for you today.

Tesla Motors (TSLA) It's pretty hard to top this one for an automaker--  Consumer Reports says the upgraded Tesla P85D Model S is the best performing car it's ever reviewed. In fact, it was so good the magazine had to rejigger its scoring system because Elon Musk's electric vehicle initially got a 103 rating out of a possible 100.

Tiffany (TIF) There were a lot of empty little blue boxes in the second quarter, as both profit and revenue fell short of estimates. The luxury retailer blames the strong dollar, saying its stores in America lost foreign customers because of high currency exchange rates. And it is forecasting disappointing full-year earnings.

Dollar General (DG) The news isn't any better on the discount side as the low price retailer topped earnings estimates but missed on revenue. Dollar General says while sales rose 7.9% most of that was attributable to new store openings. It's also reiterating its full year sales forecast.

Williams-Sonoma (WSM) The specialty home products chain disappointed investors with a weaker than expected forecast for profit and revenue in the current quarter and full year. In the second quarter, Williams-Sonoma met profit estimates and had a top line beat.

Guess? (GES) The trendy apparel maker expects current quarter earnings below what analysts had been looking for. And like Tiffany, Guess says it's being hit hard by the negative effects of the strong dollar. In the previous quarter, Guess beat estimates for both profit and revenue.

"Flash Boys" case dismissed

It’s been called the ‘Flash Boys’ case - and now it might be over, in a flash. Barclays (BCS) and major U.S. stock exchanges won dismissal of a suit brought by pension funds and other investors, accusing them of rigging the markets, in order to benefit high-frequency traders.

From Flash Boys… to holiday toys. If you thought Christmas Creep was bad last year, think again. Walmart (WMT) is kicking off its holiday layaway plan for shoppers TOMORROW, a full two weeks earlier than 2014, to give shoppers a head start on purchases.

GOP frontrunner Donald Trump is riling up his base, but not in the way you think. During a Bloomberg interview, the Donald said he wants to raise taxes on the wealthy, even himself.
