What's better than momentum? Mo' momentum.

Let's take a closer look at five of this past week's biggest scorchers.

Company

April 5 Weekly Gain My Watchlist
SmartHeat (Nasdaq: HEAT) $6.30 131% Add
Conn's (Nasdaq: CONN) $19.00 24% Add
Avon Products (NYSE: AVP) $23.42 21% Add

SmartHeat was last week's biggest gainer, more than doubling after posting its quarterly results. The maker of heat exchangers that make the coal-burning process more efficient and eco-friendly would've posted a welcome operating profit before some one-time charges.

Conn's charged higher after the consumer electronics retailer posted better-than-expected quarterly results. Comparable store sales soared 12.1% higher during the holiday quarter, and now Conn's is boosting its guidance.

Barclays Capital and UBS raised their price targets on Avon after the beauty goods giant rejected an unsolicited buyout bid valued at roughly $10 billion.

E-Commerce China Dangdang popped 20% higher on the week. The Chinese online retailer has seen its stock more than double in 2012 after getting pounded in 2011.

Theravance staged its advance after GlaxoSmithKline boosted its stake in the biotech to a 27% chunk. The two companies are currently partnering on the development of a drug to treat lung disease and asthma. The meatier stake is a show of confidence at worst and a prelude to a buyout at best.
