Most Added Stocks Go On Sale (CBOE, NDAQ, NYX, CME, AFFY, RPRX, FOLD, MPAA, DORM)

It’s always interesting to take a look at community sentiment among tickerspy’s more than 60,000 user-generated portfolios, and as the benchmarks tumble a number of the Most Added stocks over the last week slipped by -3% or more on Tuesday.

A stock’s Most Added multiple is based on the number of tickerspy members who add the stock to their portfolio over the last week in comparison to the historical average. Therefore, a multiple greater than 1x means more users than normal added the stock and vice versa.

Over the last week, 2010 IPO CBOE Holdings (CBOE) racked up a Most Added multiple of 53.1x, putting it on top of the rankings as of this writing. Shares of the exchange are slipping by -4% today as NASDAQ OMX Group (NDAQ), NYSE Euronext (NYX), and CME Group (CME) all slip by -3% or more.

Elsewhere, biopharmaceutical small-cap Affymax (AFFY) has a Most Added multiple of 25.4x as tickerspy members bet on a rebound after the stock’s recent slide. Over the last week, only Repros Therapeutics (RPRX) and Amicus Therapeutics (FOLD) have performed worse in the broad Biotechnology Stocks Index. Affymax is extending its five-day losses to more than 17% today.

The Auto Part Stocks Index has also gotten investor attention recently as Motorcar Parts of America (MPAA) and Dorman Products (DORM) rack up Most Added multiples of more than 20x. It will be interesting to see if tickerspy members were on-target with their bets as both stocks slide by more than -3%.
