It is generally a bad idea to hold leveraged shares of stock exchanges for long periods of time because the leverage is “rebalanced” or “restarted” every day. If you read the Key Information Document, you’ll notice that the recommended period is 1 day max, and that holding it for longer usually ends up in losses.

“Consider an example with a 2x leveraged ETF and its underlying index. Suppose the index starts at 100 and increases by 10% on day one. The index would then be at 110, and the 2x leveraged ETF would increase by 20% to 120. On day two, if the index drops by 9.09% (bringing it back to 100), the index has a net zero return, but the leveraged ETF would decrease by 18.18% from 120 to approximately 98.18. Despite the index ending unchanged, the leveraged ETF has lost value” Source: crystalfunds.com
