 Has anyone been able to write a function that will calculate the beta of a stock say against the ^SPX??
 
 Thank you

 Try this...
 
 
 
 
 If you try this, you’ll see that SPY’s beta is 1.00
 
 
 
 
 I don’t know the look back period in SF for its beta calculation. ??

 Ed,
 Some of those 2010 posts on Beta were mine.  I forgot; it’s he*l getting old.
