The Kraneshares CSI China Internet ETF (KWEB) is a popular ETF for options trading with 120,000 contracts traded per day on average. KWEB can be volatile but it has rebounded significantly from November of last year. Last week, a trader purchased over 20,000 of what appear to be bullish call spreads in KWEB March options. The share price needs to climb at least another 10% by March for this trade to pay off.
