Lump sum or dollar cost average?

[hagen401k]

Jeremy,
You're amazing! Love everything you're doing. I have been burdened with a pile of cash. I have been dollar cost averaging for years but have had the good fortune to make a large amount of extra money these last two years that foolishly I haven't put in the stock market. If you have a large amount of cash to be invested, do you generally go all in or DCA (regardless of whether the market is at an all time high or low)?

Thanks, Hagen

You won't know wether DCA or lump sum is better until after the fact.

Rule of thumb is that lump sum is better

The last big chunk of cash I had I did lump sum. Also with the 2nd and 3rd to last chunks of cash.
