Last Week's Biggest Stock Movers
Let's go over some of last week's best and worst performers.
YRC Worldwide (YRCW) -- Up 56 percent last week
Nasdaq's biggest winner was YRC Worldwide. Shares of the trucking network soared after posting better-than-expected quarterly results. It wasn't even close. Analysts were targeting an adjusted profit of 31 cents a share, but YRC Worldwide came through with adjusted earnings of 80 cents a share.
Supervalu (SVU) -- Up 25 percent last week
Grocery stock operators don't often make big moves, but Supervalu made it happen after revealing that it's considering spinning off its Save-A-Lot chain. The move would unlock the value in the company, and the mere possibility of a spin off got the market excited. Telsey Advisory Group and Morgan Stanley (MS) upgraded the stock following the news.
Shake Shack (SHAK) -- Up 20 percent last week
The old "Buy on the rumor, sell on the news" mantra sometimes works the other way around. Investors had been unloading shares of Shake Shack in recent weeks, and the stock shed nearly half of its value since peaking in May. The fear here was that insiders would bail once lock-up restrictions expired late last week. Stocks go public with conditions that insiders wait several months before selling.
With Shake Shack's stock soaring since its IPO six months ago, it's easy to see why folks were concerned that insiders would want to cash out when the window to do so opened late last week. They didn't, and the stock took off when it was clear that the market had overreacted by selling off the stock in recent weeks.
Yelp (YELP) -- Down 24 percent last week
The market gave Yelp a one-star review last week. The company behind the website that offers reviews of local establishments gave investors plenty of reasons to sell the stock after posting unflattering financials.
Yelp posted a small quarterly loss when Wall Street was settling for a small profit. This is the second time in a row that this has happened. Yelp also lowered its guidance, and if that's not bad enough, it also revealed that its chairman will be leaving the company and that it will be closing down its high-margin brand business. More than a half-dozen analysts downgraded Yelp following the laundry list of bad news.
Cimpress (CMPR) -- Down 19 percent last week
Cimpress didn't impress last week. The provider of a wide variety of printing services that used to be known as Vistaprint spooked investors after saying that it would no longer be offering up financial guidance. It's a surprise since Cimpress is coming off a solid quarter.
Some investors may appreciate companies that stay tight-lipped when it comes to providing financial outlooks, but the market itself can be jaded about these things. It takes the old "If you have nothing nice to say, say nothing at all" adage to heart when corporations decide to clam up, assuming that bad things are on the horizon.
Twitter (TWTR) -- Down 12 percent last week
Concerns of user growth continue to dog the social media platform. Twitter's base of active users has been decelerating on a percentage basis, and its CFO said last week that meaningful growth won't return until it reaches the mass market. He expects that to take a "considerable" amount of time, and that's not good enough for an impatient stock market.
