I all the time choose my very own shares, however for sheer novelty worth I requested ChatGPT to design a balanced portfolio of 5 FTSE 100 firms that mix revenue with long-term development. Did I agree with its conclusions?
FTSE 100 picks
First up was Nationwide Grid. I can’t say I used to be shocked. The utility is presumably the traditional UK defensive inventory and ChatGPT says: “It supplies the ability that retains Britain’s lights on and pays traders a gradual dividend yield of round 5.5%.”
As is commonly the case, ChatGPT is behind the instances. At the moment, Nationwide Grid yields lower than 4.1%. The chatbot additionally neglects one key threat: the utility is pouring tens of billions into the inexperienced power transition and that might squeeze returns. Some traders nonetheless like it, however I’m cautious.
Subsequent up, Lloyds Banking Group (LSE: LLOY). The excessive avenue financial institution is one other traditional portfolio constructing block and recently the shares have been going nice weapons. The Lloyds share value is up 62% within the 12 months, and 210% over 5.
ChatGPT says: “For an investor drip-feeding right into a Shares and Shares ISA, Lloyds just isn’t a foul option to acquire a 6%-plus yield.”
Mistaken once more. The yield is now 3.6%, decreased by its rocketing shares. Sustain, ChatGPT! The dividend yield will recuperate although. It’s forecast to pay 4.05% in 2025, rising to 4.68% in 2026.
ChatGPT says: “With rates of interest nonetheless comparatively excessive, banks proceed to make strong margins on lending.” That’s true, nevertheless it ought to have added: when rates of interest fall subsequent 12 months, these margins may very well be squeezed.
It does warn that “Lloyds stays tightly tied to the UK financial system, so a slowdown may rapidly hit income”. However it doesn’t point out that banks may very well be hit by a windfall tax within the Price range on 26 November. Traders might wish to see how that pans out earlier than contemplating it.
I’m nervous about Diageo shares
ChatGPT acquired it mistaken with its subsequent choose, for my part, spirit giants Diageo. This can be a inventory I maintain, however want I didn’t.
The Diageo share value is down 25% this 12 months and 52% over 5. ChatGPT doesn’t point out that. Or the explanations, that are that the cost-of-living disaster is hitting gross sales of the premium spirits Diageo specialises in, and considerations that weight reduction medication and Gen Z sobriety will squeeze long-term gross sales.
It’s additionally will get the price-to-earnings ratio mistaken, stating 20 when its 14. This makes its remaining conclusion, that it will “moderately pay up for reliability than chase dangerous bargains”, garbage. Diageo just isn’t dependable, however dangerous. It could be a superb restoration inventory, however I wouldn’t embody it in a ‘excellent’ portfolio.
ChatGPT supplemented these three with housebuilder Persimmon (getting the yield mistaken once more) and knowledge and analytics group RELX, which gives capital development potential and revenue. “Precisely what’s wanted in a diversified ISA.”
I believe Lloyds, Persimmon, and RELX are all value contemplating as we speak, however I’m cautious about Nationwide Grid and Diageo. I’m much more cautious about ChatGPT. Synthetic intelligence has extreme limits. I’ll follow the human selection.
