cumprod row and column

Hi there, I have a matrix of size 1000x 40. The 1000 represent weeks and 40 represent the number of assets. For each entry is a percentage of money made or lost.

I want to do the cum prod horizontally (all assets for one week), then cumprod going doing. So I have a full return for all assets.

Any help would be appreciated.
