Your desired result my be wrong, for instance for titolo aaa:

> 
>  cod_rif | titolo | quantity |   cmf   |  u_qq  |  mont   | vend 
> ---------+--------+----------+---------+--------+---------+------
>  7       | aaa    |     2500 |  25.455 |      0 | 60.0897 | f
>  26      | aaa    |    -1000 | 6.11098 |  6.176 |  6.1110 | t

> The 'summary table' should look more or less like this:

>  cod_rif | titolo | quantity |   cmf   |  u_qq  |  mont   | vend 
> ---------+--------+----------+---------+--------+---------+------
>  any     | aaa    |     1500 |  25.455 |  6.176 | 60.0897 | f

quantity: 2500 + -1000 = 1500, okay
cmf     : 25.455 + 6.11098 != 25.455, wrong
u_qq    : 0 + 6.176 = 6.176, okay
mont    : 60.0897 + 6.1110 != 60.0897, wrong


> Do you have any suggestion to achieve the result I want?

No, because i can't see a regular way or rule to calculate this...
