Monday's Top Performing Small Cap Stocks (PRM, VITA, ENOC, DVOX, SPMD)

I've said it many, many times: every day there is an opportunity to make big returns in the market on a percentage basis. This is the lure of investing in stocks generally, and in small caps specifically. Buy the right stock and you might make 20%, 50% or 100% in just a couple of days.

I'll gloss over the reality that this is extremely hard to do on a repeat basis and instead go straight to the results from yesterday's trading session. These are the stocks that made some people extremely happy on Monday - the top performing small caps in the Russell 2000 and S&P 600 Small Cap Indices:

PRIMEDIA PRM: The consumer directories publisher's stock rallied 60.3% on news that private equity group TPG Capital would take it over for $7.10 per share.

Orthovita VITA:  The $300 million market cap company, which makes products to fuse human bones, and other biosurgery products, soared 40.3% on news that Stryker Corp. SYK struck a deal to buy it for around $316 million.

EnerNOC ENOC: Credit Suisse upgraded the stock with a $23 price target. The company provides energy efficiency services. Read more at Forbes.

Dynavox DVOX: The company makes speech and language related software. Shares popped 13.7% when it announced earnings per share of $0.07, a penny above the consensus analyst estimate.

SuperMedia SPMD: The media advertising company publishes the Yellow Pages Directories. Its stock jumped 11.5% on what I interpret as spillover from traders bidding up publishing stock PRIMEDIA. The stock is still languishing - it hit a 52-week low on May 13th at $3.31.
