Good afternoon!

I just need some feedback about empirical research(asset pricing)... How many years of data would you recommend if a researcher employs daily observations? How about with monthly or yearly observations? Are there any typical cut-offs? ı

I am using daily data for seven years and have 1910 observations in order to understand the determinants of stock returns. Do you think its enough or too much?

I just wanted to get some feedback :) Thanks a lot!
