Tonix Pharmaceuticals, Quorum Health, Chesapeake Energy Stocks Moving Today

Stocks are trading mixed at midday, while oil prices rise. Among specific equities on the move today are drugmaker Tonix Pharmaceuticals Holding Corp. (NASDAQ:TNXP), hospital operator Quorum Health Corp (NYSE:QHC), and oil-and-gas stock Chesapeake Energy Corporation (NYSE:CHK). Here's a quick look at what's moving shares of TNXP, QHC, and CHK.

PTSD Drug Data Stokes Excitement on Tonix Pharmaceuticals Stock

TNXP is the top percentage gainer on the Nasdaq, up 36.2% at $5.64 on news the company will present data on a breakthrough post-traumatic stress disorder (PTSD) treatment at next week's MicroCap Conference in New York. The shares are on pace for their highest close since mid-February, and their first finish above the 120-day moving average since August. This may not be such great news for short sellers, though. At present, 3.4 million shares of Tonix Pharmaceuticals Holding Corp. are wrapped up in these bearish bets.

10-K Delay Drubs Quorum Health Shares

The worst performer on the New York Stock Exchange today, QHC has shed 11.8% to trade at $5.62, after the company reported a deeper-than-expected quarterly loss, and delayed its 10-K filing for 2016. The stock is now sitting on a 60.6% loss from the opening price on its first day of public trading last April. With a 14-day Relative Strength Index (RSI) of 27, Quorum Health Corp has fallen into oversold territory for the first time since early November.

Chesapeake Energy Stock Booms on Rising Oil

CHK is up 9.3% at $5.89, making it the second best performer on the S&P 500 Index (SPX). The shares seem to be benefiting from a boost in oil prices. The gains have helped Chesapeake Energy Corporation pare its year-to-date deficit to 16%, but the shares are still staring up at potential resistance from both the 50- and 200-day moving averages, which just flashed a death cross. Still, today's rally could come as a relief to options traders, who have purchased CHK calls at more than five times the rate of puts over the past 10 weeks. In fact, the stock's 50-day call/put volume ratio of 5.11 on the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX) ranks in the bullishly skewed 78th annual percentile.
