Hence the distribution you’ll be using to maximise the likelihood of the observed price will be wider than otherwise. First, what you ought to be regressing are returns, not prices.
If not, what would be the proper convention? Estimating betas from nonsynchronous data.

Second, by interpolating you’re underestimating the variance of the asset price in the interval between index price observations. There’s really no betss convention here.
You’ll have to assume a parameterized family of joint stochastic processes and estimate the parameters given the price observations.
