Tuesday's Top Performing Small Cap Stocks (RLRN, FN, PTX, VSEC, FSTR)

All good things come to an end, and the curtain came down on a three-day run-up in small-cap stocks on Tuesday.

The Russell 2000 Index fell for the first time since August 10, after the index had rebounded from the recent sell-offs by nearly 9 percent.

Yet there were some rising stars to be found across many sectors, including old-line and high-tech manufacturing, biotechs and software developers and a couple of acquisitions.

Crude Carriers CRU, a small cap not part of the Russell 2K or S&P Small Cap 600, closed 22.1 percent higher. The Marshall Islands-domiciled, Greek-headquartered tanker operator, which pays a dividend currently yielding 14 percent, is being taken over by Capital Product Partners L.P.

For the day, the Russell 2000 Index lost 1.93 percent in value, while the Standard & Poor's Small Cap 600 was down 1.75 percent. By comparison, the Dow Jones Industrial Average was off 0.67 percent, the S&P 500 closed 0.97 percent lower, and the Nasdaq Stock Market finished down 1.24 percent.
