You're incorrect whether you'd like to admit it or not. Lump sum is investing every dollar that comes in as soon as it comes in DCA is typically done when someone gets a windfall and is afraid of dumping in so the spread it out. That's market timing.
But if it makes you FEEL better do whatever you please I don't care
DCA = risk reduction. Not saying DCA will produce more return, just that it's a lower level of risk.
No. DCA does not reduce risk, it just replaces one risk for another. If you invest in lump sum right now, you're predicting that the market will go up. If you begin DCA'ing now, you're assuming that there'll be a dip or crash in the next few months.
If there ISN'T a dip or crash in the next few months, and the market instead carries on its slow upward crawl, then you lose money for several reasons: 1. you buy stock at every-increasing prices, meaning you end up with less than you would have had if you'd bought it all at day one. 2. you miss out on any potential dividends that that money would have brought you had it been in the stock market. 3. inflation; holding it in cash while you wait for your next dip of the toes means that the rodents of inflation nibble away at it, further reducing the amount of stock you'll get when you come in again for your next toe-dip.
That market always goes up over time, so lump sum investing is always the better strategy.

DCA'ing replaces one unlikely risk with another, much more likely risk.
