potential error in code

[turmeric-blend]

hi, thanks for the work on this. I am looking at markowitz_tuning.ipynb for the simulate() function.

def simulate(ht, ut):
    ret = torch.exp(logreturn1p_dist.sample())
    ht = ret * (ht + ut)                  <----- this line
    return ht, ret

from my understanding, ht should be (ret * (ht + ut))/(ret.T @ (ht + ut)) as per formula stated for how holdings evolve in 5.3 of the paper? This formula sums to 1 (as holdings should be), while the line in code doesn't.
