Some stocks take a pounding, but there's usually what they call a dead-cat bounce. Even if a stock's inevitable path is to head lower, there's usually a respite in the downticks.

It doesn't always pan out that way.

More than a few actively traded companies fell every single trading day last week, and more often than not it happened without any material news. Investors just decided to move on, and the small daily downticks added up to double-digit percentage share-price declines.

Let's take a closer look at a few companies that saw their share prices drop in each of this past week's trading days.

True to its name, Eagle Bulk Shipping is a transporter of dry bulk cargo. These have been hard times for bulk shippers given the dicey global economy, and it was evident in Eagle's quarterly report last week. Eagle posted a widening deficit of $1.92 a share on a 39% plunge in revenue. After generating a loss of $6.30 a share for all of 2012, Eagle had better hope that the climate for dry bulk shippers improves sooner rather than later.

Ruckus Wireless went public at $15 in November. After it rallied in the weeks following its IPO, inertia certainly seems to be pulling the stock back to its original price tag. Since closing at $23.96 on March 19, shares of Ruckus have moved lower for 12 consecutive days.

Think about that streak for a moment. The chances of a stock closing lower for a dozen consecutive days is a mere 0.02% in a neutral environment.

There hasn't been any bad news out on the supplier of wireless systems for the mobile Internet infrastructure market. Investors simply seem to be wanting to hit the exits before next month's lockup expiration.

PacBio is a provider of genetic diagnostics. The stock dipped into the single digits two summers ago, and it hasn't surfaced back into the double digits ever since. Chunky quarterly deficits haven't helped, and investors who have taken instances of insider buying as signaling a bottom have been burned.

Manitowoc drifted lower despite some bullish encouragement from CNBC's Jim Cramer. His argument is that Manitowoc's crane business should continue to benefit from improving construction trends. Cramer also believes that it should spin off its food services business, suggesting that Manitowoc is worth more than the current sum of its parts.

PTC is another company that slipped all five trading days without any notable negative events ushering investors to the exits. The provider of technology solutions for companies managing a product's lifecycle has largely done everything right. PTC has beaten Wall Street's profit targets in each of the past four quarters, and back in January issued an upbeat outlook for 2013.

Investors just didn't want anything to do with PTC last week, but it's a new week now.
