I see that there is a type of investment called Daily Leverage Certificate which allows investor to buy a certificate tracking an index with multiple leverage factor. Meaning to say that if the index moves by 1% and the leverage is 5x, then the certificate's value moves by 5%. And the performance of the certificate is reset daily. Here is an example.
For such type of investments, the management fees and other fees are high, it can be 5% or so p.a. And due to this, will someday the value of the certificate drops close to 0? It's highly unlikely that an index can perform higher than 5% consistently. Also, this kind of certificate has Long and Short certificates too.
