speculative stocks

[Otter]

I don't own anything that fits the bill, but UVXY is capable of giving you a helluva ride (to the upside or the down). If you think the market is going to have another December crash (or worse) in the immediate future, it would be a solid speculative play on increased volatility. If the market stays calm and upwards, thanks to Fed dovishness, you'll lose pretty much your entire investment thanks to contango.
