I believe your DCA approach is exactly what most 401K funds do.
put money in every month, very diversified(just like SPY is for SP500)
It's very easy to back test SPY with DCA for the past 10 years
to see how good it turned out, but if you pick
QQQQ, it may take another 10+ years to see Nasdaq in 5000 again
【在 r*m 的大作中提到】
: 哈哈,我还有半句没说完:
: 最最关键的是要始终让自己有坚持下去的资本,最悲剧的莫过于被剥夺游戏资格。
: 只要我不是一把all in,我甚至可以明确告诉庄家我的计划(比如每个月发工资买入
: sp500, DCA,直到我出水,赚钱,赚很多钱),庄家又奈何?

What Does Dollar-Cost Averaging - DCA Mean?
The technique of buying a fixed dollar amount of a particular investment on a regular schedule, regardless of the share price. More shares are purchased when prices are low, and fewer shares are bought when prices are high.
Also referred to as a "constant dollar plan".
Investopedia explains Dollar-Cost Averaging - DCA
Eventually, the average cost per share of the security will become smaller and smaller. Dollar-cost averaging lessens the risk of investing a large amount in a single investment at the wrong time.
For example, you decide to purchase $100 worth of XYZ each month for three months. In January, XYZ is worth $33, so you buy three shares. In February, XYZ is worth $25, so you buy four additional shares this time. Finally, in March, XYZ is worth $20, so you buy five shares. In total, you purchased 12 shares for an average price of approximately $25 each.
In the U.K., it is known as "pound-cost averaging".
