a few points

1. for allocation reasons, my targeted average is 60%, give or take 10%.... so I went up to 70% during the april-september shake period.... i am currently at 45% + put options, due to having to move some accounts.. 

2. nobody knows if the market is going up for sure... right now there is better odds that it's trending up... but there are always chances to trade around a core position by adding on dips and lightening on pops.... although it can get tricky and dependent on trading skills.

3. yes I do have about 30-40% 'idle capacity'..... some are invested in bonds (sold them all out weeks ago), some are used for options, some are just sitting in cash, some for other stuff... at this stage, it's no longer about maximizing the returns any more... I love my job and I will never run out of money to spend, so it's about balancing returns/risks at this stage of my investments.
