I never owned either, until I recently got assigned GOOG via OTM cash-covered puts. GOOG dropped quite a bit, and the value was decent enough for me to take some risk.
Well, GOOG dropped some more, and I am currently down -12%. But that's OK. You cannot expect to win immediately with every purchase. I may add to this position gradually.
I am looking to accumulate some more tech stocks that are beaten down. I think MSFT is also fairly valued, and would not mind building a position. I will get it via writing OTM puts like I usually do.
PS. Currently, these growth 2 stocks are not commanding a higher value than the total S&P. It means I am not paying a premium for the potential growth. I like it when I am not overpaying for the growth prospect. I really don't know which one is better, but think that they are comparable. And I always want to diversify.
