NEW YORK (MarketWatch) -- U.S. stocks ended Monday with modest gains as Apple Inc., Hasbro Inc. and Tesla Motors Inc. extended a rebound many strategists say is still fragile.

The S&P 500 (SPX) closed 2.82 points, or 0.2%, higher at 1,799.84. The benchmark index fell as much as 5.8% from its peak before rebounding on Thursday. After Monday's modest gains, it is 2.6% below its all-time high reached on Jan 15. Health-care and utilities led gains among the index's 10 sectors on Monday.

The Dow Jones Industrial Average (DJI) traded in negative territory most of the session but managed to rise in the last hour of trading and closed up 7.71 points, or 0.1%, at 15,801.79. Travelers Cos. (TRV) and Walt Disney Co. (DIS) led gains among the Dow's 30 stocks.

The Nasdaq Composite (RIXF) rose 22.31 points, or 0.5%, to 4,148.17.

The stock market began the session on a cautious note ahead of Federal Reserve Chairwoman Janet Yellen's testimony on Tuesday. Read the recap of our stock market live blog.

But stocks turned broadly higher in afternoon trading, countering some skepticism that the market rebound started last week will be short-lived.

Gary Thayer, chief macro strategist at Wells Fargo Advisors, wrote that at this point it is too early to say the decline is equities is over.

"We believe the increase in the U.S. equity market late last week may have only been an oversold bounce after the sharp selloff in late January and early February. Therefore, it is probably too early to conclude that the correction in the U.S. stock market is over," Thayer wrote in a research note.

"Sentiment could turn negative again in the weeks ahead if there is additional negative news," he added.

Stocks rallied on Thursday and Friday as investors found positive aspects in both jobless claims and the jobs report, even though the number of jobs created last month fell short of expectations.

Channing Smith, managing director at Capital Advisors, says that this week will be critical to validate the bearish view if the S&P 500 tests its 100-day moving average.

"In the near-term, it looks like the S&P 500 is between 50-day and 100-day moving averages. If it falls below the 100-day moving average, then we expect more downside," Smith said.

"In the longer-term, we do not see much risk for a great selloff, as credit spreads remain healthy and the 10-year yields are stable. Though we are watching the emerging markets carefully," he added.

This week investors will focus on Fed Chairwoman Yellen's first semi-annual monetary policy testimony to Congress, coming on Tuesday. She is scheduled to appear before the Senate Banking Committee on Thursday. History shows that her predecessor Ben Bernanke has given the market a boost in the past with those testimonies.

Leading gains on the S&P 500, Hasbro Inc. (HAS) shares rose 4.5% after the toymaker reported results.

Apple Inc. (AAPL) shares rose 1.8% after activist investor Carl Icahn backed off a bit from some of his rhetoric regarding Apple's share buyback efforts. In a open letter to Apple shareholders, Icahn said he was "supportive" of Apple recently buying back $14 billion of its stock. Apple is the biggest weight on the Nasdaq Composite and S&P 500.

Tesla Motors Co. (TSLA) rallied 5.4%, the best on the Nasdaq 100 (NDX) , ahead of earnings next week. It notched a new intraday record just under $200.

McDonald's Corp. (MCD) said its global same-store sales improved in January, with stronger performances in China and Europe making up for softness in the U.S. Shares in the Dow component were 1.1% lower.

Shares in Loews Corp. (L) fell 4.3%, making it the worst performer on the S&P 500 index. The company said its fourth-quarter loss widened owing to impairment charges that offset growth for its CNA Financial Corp. (CNA) unit .

Yelp Inc. (YELP) pared initial sharp gains and closed 1.9% higher following reports that Yahoo Inc. will incorporate Yelp's listings and reviews of local businesses into results on Yahoo's search engine.

In other markets, European stocks closed mostly flat, Asian stocks closed higher after last week's brutal selling. The U.S. dollar weakened slightly against the yen, oil prices topped $100 while gold futures gained for the fourth straight session.
