            Q: I hold NVDA (7.5%), VRT (7%), MSFT (5.5%), AMZN (7%), and GOOG  (5%)-  all up significantly in registered accounts.  Question #1:  what is the maximum weight you would be comfortable holding of each of these five stocks?  Question #2:  I also hold LMN (2.5%), which is barely above water. Deeply disappointed in its recent performance and considering replacing it with either ISRG or AVGO.  That said, I'm concerned that adding AVGO puts too many eggs in the AI basket, given my other holdings.  If this were your portfolio, would you opt to replace LMN with either ISRG or AVGO? Please explain why.
