SAN FRANCISCO (MarketWatch) -- Tech stocks are seeing another day of erratic trading Tuesday as the sector kept slipping into the red, only to rebound briefly, before retreating again in what looks like an ongoing tug-of-war for investors' sentiment.

Among leading tech stocks, Internet radio leader Pandora Media Inc. (P) rose almost 4%, and Google Inc. (GOOGL), Netflix Inc. (NFLX) and Yahoo Inc. (YHOO) were each up around 2%.

The Nasdaq Composite Index (RIXF) came back from a round of losses to rise 18 points to 4.089. The tech-heavy market gauge is trying to find some stability after losing almost 5% over the prior three trading sessions.

The tech sector generally mirrored the movement of the broader market, which also fluctuated. Adding to investors' concerns was a new report from the International Monetary Fund, which said economic shockwaves in emerging markets could end up negatively impacting several Western economies.

Among other tech stocks, Amazon.com Inc. (AMZN) rose 2% to $324.89 after the company cited new market data that said its Prime Instant Video service usage tripled from a year ago, and that it surpassed both Hulu and Apple Inc. (AAPL) in streaming video use.

Yelp Inc. (YELP) shares rose 3% to $68.25 after SunTrust Robinson Humphrey analyst Robert Peck raised his rating on the online consumer review and information company to buy from neutral, saying in a research note that Yelp's stock price valuation is more supportive following a 33% decline in the past month.
