Putting it all in at once makes the tax a bit easier.Hi,
I have 50k that I am looking to put into ETFs via Trade Republic.
Would I be better drip feeding a few K a week or putting in lump sum?
Appreciate any advice
Lump-sum investment strategies beat common cost averaging investment strategies two-thirds of the time, according to historical and simulated market data.

Normally it would be the other way around especially if there's some fixed case cost to a trade?I'd note that the investment management company gets more fees if you put the money in all at once.
I was referring to the specific study referenced, which was put together by Vanguard.Anyway, isn't it free on Trade Republic?
That’s fair, Vanguard may not be unbiased.That's a very light weight study with some very specific assumptions, investing in 3 months versus all at once and only looks at single year returns. I'd note that the investment management company gets more fees if you put the money in all at once.
Yep, I reckon a company with $9.3 trillion dollars under management is going to trick people into investing in lump sums rather than over 3-6 months, so they can get a higher management fee sooner.That's a very light weight study with some very specific assumptions, investing in 3 months versus all at once and only looks at single year returns.

I think there is something up with your analysis there, are you assuming they only have one customer?Yep, I reckon a company with $9.3 trillion dollars under management is going to trick people into investing in lump sums rather than over 3-6 months, so they can get a higher management fee sooner.
The Global Stock Index charges 0.18%. For €100,000, that's €180 a year or €15 a month. If I drip the €100,000 over 10 months, they get €82.50 in fees instead of €150 before the two amounts are equalised and paying almost the same (assuming the lump sum does grow by more).
I think one of the largest fund managers can take the hit instead of fabricating reports to make an extra €67.50![]()
Here's a paper by Michael Brennan, ex editor of the journal of Finance (and co authors), that was published in the Review of Finance:That’s fair, Vanguard may not be unbiased.
Here is an academic paper coming to the same conclusion - https://www.researchgate.net/public...dence_from_investing_simulations_on_real_data while this one comes to a more middle of the road conclusion - https://nsuworks.nova.edu/hcbe_facarticles/769
My personal experience was having a large lump sum to invest in late 2022, knowing that investing as a lump sum made for a more positive outcome but deciding to dollar-cost-average instead over a few months to ‘reduce my risk’. October 2022 when I bought my first tranche turned out to be the bottom of the NASDAQ100 and I missed out on 50% growth as I DCA’d in over the next 6 months. Never again.
Jeysus, 5% a month? You're certainly dragging it outPersonally, I wouldn’t invest using ETF’s due to exit and deemed disposal tax.
As regards DCA versus all in for a lump sum, the method I have used was,
40% invested in first month.
Further 5% of the original total then invested each month.
However, if the target investment vehicle dropped by 5% or more in value in a month, I brought forward the next instalment.
It was like an each way bet and would cushion somewhat any potential regret.
It could have been better but it could have been worse
This is it. I explain to clients that 2/3 of the time, they are better off to invest in a lump sum. But if they feel nervous about investing a lump sum, in one go, spread it out over 6 months. It is likely that they will be worse off but they won't be anxious about their investment and if values fall, they will only be down on 16% of their money and will buy in at a lower price. Likewise, if markets go up, only 16% of their money will grow and their next installment is bought at a higher price.They report benefits to investors using dollar cost averaging to add stocks to a portfolio, and for index investment for more risk averse investors. In the end it comes down to individual preferences and utility again. I don't think it is wise to give rule of thumb advice that it is always better to go for lump sum or irrational to use DCA.
In your experience, if the Nasdaq had gone down 50% instead of up it's likely you'd have bigger regret in losing 50% than the regret you have over the missed upside. If someone is about to invest and they think both scenarios through and that isn't the case then they should go for the lump sum because they have low risk aversion. It's hard to see things going up 50% from here, but might be technically feasible when the US department of government efficiency kicks in...
I had a lump of cash in DC Pension transferred in in July 2022.Nobody can know that for one specific instance whether lump sum vs cost averaging will get a better return.
E.g. with that 50K, if it was invested in one go, but the market was to decline gradually over the next year, then you would have been better off cost averaging at 4K per month, getting more for your money as the price fell each month. And if it gradually went up, then lump sum would be better.
But as the market has historically grown over time, and had more up periods than down periods, then across a population, lump sum will outperform cost averaging. Just not for everyone, and not all the time.
Right now, we are close to a market all time high - but predicting the future based on that - well that’s just trying to time the market.
Having said all that, my own preference would be for cost averaging - it just feels easier for psychological reasons.
