LONDON -- With the FTSE 100 (FTSEINDICES:^FTSE) in a gloomy mood, there were few stocks moving upward last week. London's top index put in its third losing week in a row, ending 59 points down at 6,454, as the weaker-than-expected Chinese economy and the U.S. budget deficit dampened enthusiasm. What individual movement was there? Here's one gainer and a few losses.

Aviva (LSE:AV)
Insurer Aviva has been doing well, with its price up more than 40% since April's lows, and this week it enjoyed a modest boost of 11.4 pence (1.8%) to 415 pence after completing the disposal of Aviva USA. The sale, to Athene Holding, raised $2.6 billion, which was $0.8 billion more than originally announced last December because of earnings and other improvements during the last quarter.

Unilever (LSE:ULVR)
A trading statement on Monday led Unilever shares to end the week down 91 pence (3.7%) to 2,366 pence, after the company warned of weakening emerging markets. Telling us it expects underlying sales growth of 3% to 3.5% during the quarter, the consumer-brands giant said the slowdown "has accelerated as a result of significant currency weakening." Recent falls have reversed a strong start to 2013, with the Unilever price now pretty much unchanged from 12 months ago.

Aggreko (LSE:AGK)
The Unilever warning also led to a fall for Aggreko, of 166 pence (10.3%) to 1,442 pence, as the equipment rental provider has a large overseas presence and prices its services in dollars. The company was hit by a subsequent downgrade by Barclays, which warned that Aggreko's competitiveness has been eroded as local costs of its rental equipment are rising as a result of these currency movements.

Intertek (LSE:ITRK)}
Intertek fell 127 pence (3.8%) to 3,219 pence during the week, though 15 pence of that drop was due to the passing of the company's ex-dividend date on Wednesday. The other news was Thursday's announcement of an acquisition, with the quality and safety specialist having bought Louisiana-based Global X-Ray & Testing, or GXT, a provider of testing services to the oil and gas sector. Chief executive Wolfhart Hauser said GXT "fits well with our existing portfolio of Industrial inspection services."
