comment good R package for vectorized option pricing
what do you mean by vectorized? Getting price and delta with one function call? Or getting the price for a bunch of options with one call?

comment Covariance between two stocks in a two-factor model
You write "the factor model is" and then two numbers. This is not a model. Do the 2 stocks "have" 2 different models? This is very unclear. Please format the question and insert the formulas that describe the models.

comment The Distribution of Future Stock Price
It is difficult to say what is meant if they do not state it explicetly. But the word "instantaneous drift" could point to the GBM setting - thus lognormal prices ( i.e. log returns are normal).

comment Seasonal patterns in financial markets (weekday effects)
I usually like looking at rather recent data just because I think that the world changes and that e.g. 2008-2014 is more relevant for today than periods before that. Thus looking at the link there seems to be quite a strong pattern showing reversal in the period 2006-2010. I would love to see more recent data too. But for this period the effect looks strong to me - although in general the article summarizes that the effect is not reliable. Maybe not at all times - maybe not in old days but today !? ;)
