CLOSE: BIDU Short Straddle= +27.5% ROI

I started this short straddle on 2/13 for BIDU.

Today, the volatility has finally crushed completely, meaning days after earnings has been announced, volatility has stopped dropping and is now starting to turn upward. So, I bought back the Mar 250 Call & Put for a total debit of $39.25.

When I opened this trade, I made $54.15 credit, so that gives me an ROI of $14.90/54.15= 27.5%
