Morning,
There is no perfect answer here. Based on what you quickly stated, you are looking for a portfolio that is easier to manage and less cumbersome in terms of time required to monitor. With that in mind, and if i were in your position, I'd likely start with trimming my stocks down to a reasonable number (that will vary on the person). I am not sure how many positions you have, but first, I'd start to trim those with higher risk and keep those that are more 'foundational' in nature. Stocks that aren't really high growth, but have a history of providing consistent and steady returns. You can also sort your stocks by BETA to see which ones are highly volatile and which ones tend to track closer to the market. The ones that are highly volatile typically require more attention, so you could start by moving those as well.
The funds I'd redeploy into either the stocks I'm keeping or into a basket of ETFs.
The second step I'd take if I wanted to take it further, is to dispose of all my stocks and go to an all-ETF style portfolio. Select a handful of ETFs that get me well diversified across industries and globally. I'd also stay away from mutual funds.
I would, however, do this in a staged approach so that I'm not rushing into a decision. There are so many ways to do this, but at a high level, this is how I'd personally approach this situation. Might not work for you, but it is one way to approach it.
