<div id="readability-page-1">Texas-based utility stock Vistra Corp (NYSE:VST) is slipping today, down 5.7% at $205.49 at last glance, after suffering a downgrade from Jefferies to &#34;hold&#34; from &#34;buy.&#34; The firm also slashed its price target to $230 from $241, following the stock's meteoric rise “beyond what any bull could have predicted years ago.” VST hit a record high of $219.73 just last session, a large jump from the $30 level it was trading around two years ago. The stock's most recent climb pushed it above a coalition of short-term moving averages, including former pressure at the 20-day trendline. Since the start of the month, the equity is still up 9.3%. The stock already looked due for a short-term dip. This is per its 14-day Relative Strength Index (RSI) of 80.9, which sits in &#34;overbought&#34; territory. Options bulls likely cheered yesterday's peak, as calls have been much more popular than usual in the options pits over the last two weeks. VST's 10-day call/put volume ratio of 2.57 at the International Securities Exchange (ISE), Cboe Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX) ranks higher than 95% of readings from the past year. Options look like a good way to go when weighing in on Vistra stock's next move. The security's Schaeffer's Volatility Index (SVI) of 55% ranks in the 10th percentile of its annual range, meaning options traders are pricing in low volatility expectations. </div>
