This is an interesting idea, but if I were going to do it, I’d be tempted to use an ETF like FXI instead of BABA or BIDU. It has much more liquidity than either of those two names (in terms of open interest and bid-ask spread), and its straddle price is a much lower percentage of the stock price, so it’s easier to get into with a smaller account.
Granted, the absolute dollar moves are likely to much less, but the percentage move could be higher. It’s currently at a higher IV rank at the moment, which is something to keep in mind, but I think the other factors (especially liquidity) would make this a better choice for personally.
Just a thought.
