Ive written a piece about The IPO trap here https://open.substack.com/pub/marcwestlake/p/the-ipo-trap?r=6xvrb4&utm_medium=ios
The US saw massive inflows of $1.5Trillion into passive ETFs in 2025.
In theory since the inflows are channelled into the market in proportion to current market cap one might have expected that they would not of themselves affect the market cap proportions. But apparently "academic research" says differently. A lot of those inflows are from declining active funds. That process must have limits and it begs the question of what will be the effect when passive cashflow stabilises or even goes into reverse.
From @Marc's post 501 their impact will only be about 1% of the index.This will be tested soon when three new mega-caps enter the index. From the FT:
Ha ha! You forgot the prelude, Duke. It fell 50% shortly after I bought it. As @Marc likes to point out, it then has to rise 100% to recover the loss.I see Godwin is up about 20% in a matter of months. Missed the boat again, damn
Agreed, Brendan! Yet it was a nice short-term outcome - far better than the opposite, as has happened to me on occasion, e.g., with Goodwin.Colm - it's too short a timeframe to make such a call.
Come back to us in a year and then in 5 years.
So, does this follow..?
If you're re-balancing a portfolio and one of your holdings is in the bargain basement and you believe the analysis of its fundamentals are sound....then shouldn't you sell some of your other holdings with lesser growth prospects (as determined by analysis)and buy the dip.
Thank you, askaboutmoney
Agreed, especially considering all the earlier posts equating UK life assurance shares to bonds based on their dividends.Intuitively I'd be inclined to reverse the trade now , and swap Nvidia for Standard life and "bank" the arbitrage .
I don't agree.Intuitively I'd be inclined to reverse the trade now , and swap Nvidia for Standard life and "bank" the arbitrage . More smoothing?
I know nothing about stock trading but the psychology of what next is fascinating. I'm very interested in behavioural economics and psychology. FOMO, risk aversion, et al.
A few days later (20 May), Nvidia reported earnings per share for the latest quarter. They were 36% higher than the previous quarter (up from $1.76 to $2.39). On the basis of the updated back-of-an-envelope calculation, I decided that Nvidia offered better long-term prospects than Standard Life.I decided to take an old actuary’s look at NVIDIA, a darling of stock market bulls. It accounts for close to 10% of my pension portfolio.
Its earnings in the quarter to 26 January last were $1.76 a share, having grown by an average 19% a quarter from the corresponding quarter in 2025.
I decided that it was reasonable to assume average earnings growth of 10% a quarter for the next eight quarters, and for the share to be valued then at twenty times annualised earnings (eighty times quarterly earnings) and that it would be appropriate to discount that at 15% a year to get a reasonable current value for the share.
The calculation is as follows (roll the drums!!!):
1.76 * (1.10)^8 * 4*20/(1.15^2) = $228.
NVIDIA’s closing price on Friday last (15 May) was $225.32. The conclusion therefore, on my back-of-a-fag packet model, is that the share is reasonably priced at present. In fact, I think my assumptions may err on the cautious side, so I’m comfortable continuing to hold the share at its current price.
That's the great thing about ignoring losses, you never lose.After doing the sums, I am happy to report that, ignoring the Goodwin debacle – a very important qualifier - the fund is now worth slightly more than it would be worth if I had done nothing and held on to all my Standard Life and L&G shares.
Isn't that usually the case for everyone?The pension fund is worth less that if I had left everything untouched
Going back to the very first post that started this epic thread, I really don't understand why you didn't just go passive. But I guess that you enjoy the work involved in actively managing your own pension investments?Isn't that usually the case for everyone?
My stock selection wasn't great, to put it mildly. I would have done far better by investing in a passive world equity fund.
We've had this discussion many times. If I'd gone passive, I would never have had the courage to invest entirely in equities. I would have invested at least 30% in bonds or in a managed fund with a significant bond element. I thought about putting a portion of the fund in bonds, but decided it would be stupid to condemn myself to a guaranteed low return for a portion of the fund. Standard Life and L&G can be considered as bond proxies. They have high dividend yields, probably twice what I would get from bonds. I think those dividends are safe. I could be proved wrong, of course. They also have the potential to deliver long-term capital growth. Bonds don't. The end result is an average return on the entire fund of more than 10% a year since I started drawing from my pension account more than 15 years ago. The fund is now worth around twice what I invested at the start, despite my taking nearly 6% (of current value) every year. I hope to give more precise figures after 30 June.I really don't understand why you didn't just go passive.
Actually, there's very little work involved. As recorded previously, there were no transactions whatsoever in 2023. No purchases, no sales. The 6% 'income' came entirely from dividends and from running down the cash in the fund.But I guess that you enjoy the work involved in actively managing your own pension investments?
After tax!!is now worth €21 million from an initial investment of €80,000 fifteen years ago, mainly by taking long and short positions in biotech companies. That’s equivalent to a return of 45% a year
