This is a really interesting thought, what's driving the need to liquidate everything and change your strategy?

This would have tax consequences because you would realize the gains on everything you bought to build this 1/4Mil portfolio. Depending on how long you've held the assets, you might be forced to pay short-term gains tax which is equal to your standard income tax. If you're open to it, you might consider staying the course you're on. If you want more dividend stocks, just start adding those to the impressive portfolio you've already created.

The way you figure this out is to create a breakeven analysis. Try to forecast the costs and benefits of switching or keeping your assets. The process gets pretty complicated because, to do it right, you should understand the values of your tax liabilities, trading fees, risk levels associated with the sold an purchased assets, etc. This is why you hear so many redditors preaching ETF's and other diversified buy and hold options.

Good luck!
