The answer to your question is a qualified "Yes", it makes sense to heavily overweight growth stocks.......currently.
In addition to the domestic equity markets trading cyclically, the style components that exist in the market (growth/value, equal weighted/capitalization weighted, large cap/mid-cap/small cap) all also trade cyclically. The challenge investors and most advisors face is to determine which style(s) is/are currently outperforming or undeperforming.
For over 20 years, I have been a student and practitioner of Point and Figure charting or Pn'F as refined by Tom Dorsey at Dorsey Wright and Associates. Tom has written a good primer on the methodology for both investors and advisors called, surprisingly, Point & Figure Charting. The book is available on Amazon.. By subscritption, DW also provides subscribers and advisors with a wealth of market information and education. As part of that data feed, there are various models imbedded in the recommendations. Confining the discussion to US markets as an example, currently favored market components would be equal weighted small cap growth, equal weighted mid, cap growth and across the spctrum with value standing last. During my use of the Dorsey method, I have seen value outweigh growth, but again, not currently.
When will the sectors change? They'll give you signs beforehand and usually well in advance of when the media picks up the indications, but for now, growth stocks are carrying the day. Considering all of this, perhaps the bulk of your investments should be allocated toward growth currently.
Hope this helps.
