Tesla Inc.’s (TSLA, -0.66%) stock options were priced to move more than usual in one day after the electric vehicle maker reported results for its second quarter after Wednesday’s close. According to Matt Amberson, principal of Option Research & Technology Services, a straddle is a pure volatility play which involves buying bullish (calls), and bearish options (puts) with the same strike prices (current price). The move on Thursday will be $21.56 either way. According to the current $294.78 price, this would be a 7.3% movement, meaning a buyer of a straddle could make money on Thursday if the stock closed above $316.34, or below $273.22. Amberson says that the price movement of the straddle is 25 percent more than the average move in the stock’s price over the last 12 quarters. Tesla’s shares, which rose 0.5% to a 10-month-high in midday trading before the results were announced, have risen 63.2% during the last three months, while the S&P 500 SPX, +0.28%has gained 9.9%.
