Today's abbreviated trading may be yielding positive results for the major indexes, but there are still some stubborn stocks out there bucking the broader trend higher. Currently, the New York Stock Exchange (NYSE) has four securities at new bottoms, while the Nasdaq shows 14 at fresh lows. Among the stocks touching 52-week lows in today's session are Groupon Inc (NASDAQ:GRPN - 8.91), RadioShack Corporation (NYSE:RSH - 3.86), and CTC Media, Inc. (NASDAQ:CTCM - 7.21).

• GRPN has shed more than 6% and tagged a new low of $8.72 today, after it was reported that Chairman Eric Lefkofsky will limit his involvement with the company to focus on Lightbank, his venture capital firm. The news merely adds to the beleaguered stock's troubles of late, which has contracted by nearly 57% so far this year. Meanwhile, the equity has been eyed closely by skeptics over the past several weeks, as short interest on GRPN ramped up by roughly 18% during the past month. These shorted shares now account for a lofty 11% of the security's available float.
  
  
• RSH has added about 1.2% today, but not before falling to a new all-time bottom of $3.67 earlier in the session. The stock has been in some hot water well before now, however, considering its year-over-year decline of almost 72%. Things look just as brutal in the options pits, as traders on the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX) have bought to open 1.37 puts for every call during the past 50 sessions. In fact, this ratio is just two percentage points from an annual high, signaling that speculators have rarely purchased bearish options over bullish at a faster pace during the past year.
  
  
• Shares of CTCM plummeted about 9.7% today -- reaching a new three-year low of $7.15 -- after being downgraded to "neutral" from "buy" and having its price target slashed to $8.80 from $15.20 at UBS ahead of the bell. Currently, the Russian broadcasting issue sits on a 52-week loss of close to 68%, which has likely attracted a large number of bearish speculators. In fact, the Schaeffer's put/call open interest ratio (SOIR) for CTCM checks in at 5.35, indicating that puts outweigh calls by more than five to one among the stock's front three-months' series of options. With an annual percentile ranking of 86%, it can be discerned that short-term options players have been more put-heavy toward the stock just 14% of the time over the last 12 months.
