We study the large deviation behaviour of Sn=∑j=1n WjZj, where (Wj)j ∈ \mathbb N and (Zj)j ∈ \mathbb N are sequences of real-valued, independent and identically distributed random variables satisfying certain moment conditions, independent of each other. More precisely, we prove a conditional strong large deviation result and describe the fluctuations of the random rate function through a functional central limit theorem.
