AI Market Soars Backed by Heavyweight Investors While Concentration Rises

Are
AI stocks still an intelligent investment?

At
its October meeting, the Bank of England’s financial policy committee noted
that measures of risk premia across many asset classes had tightened since
June.

It
concluded that equity market valuations appear stretched on a number of
measures ‘particularly for technology companies focused on artificial intelligence’
and that when combined with increasing concentration within market indices, this
‘leaves equity markets particularly exposed should expectations around the
impact of AI become less optimistic’.

The
committee is also not alone in expressing concern around concentration of US
equities, with the five largest companies on the S&P 500 now accounting for
almost 30% of market share – the highest level since the mid-1980s.

Parallels
have been drawn with market conditions prior to the dotcom crash at the end of
the last century, particularly the sharp rise in tech stock valuations and
speculative trading as well as the extensive use of circular financing – of
which vendor financing was a key feature in the late 1990s.

As
with most tech sector stocks, AI company valuations are based on expectations
of future adoption. Many investors remain confident that when it comes to
artificial intelligence, Amara’s law (that the effect of a technology is
overestimated in the short run and underestimated in the longer term) will come
to pass.

There
are significant potential obstacles to these valuations being realised though. Competition
could increase and constraints on resources such as power and water could hold
back infrastructure development, while new models for delivering services could
render some of the anticipated infrastructure requirements obsolete.

However,
there will still be winners and it should be noted that some of the biggest
names in this space have heavyweight backers. There is also a sense among
market veterans that investment is much more focused on companies with a solid
businesses model than it was at the height of the dotcom boom.

With
a September report from JP Morgan noting that AI-related capital expenditure was
a more significant factor than consumer spending in US GDP growth that month, maybe
investors should just strap and enjoy the ride.

24-hour

In
an increasingly interconnected world, enabling round-the-clock stock trading
has long seemed like a logical progression.

Earlier
this month, trading of US equities between 4am and 8pm ET commenced on 24X
National Exchange . The exchange says it plans to offer 23-hour weekday trading in
the second half of next year.

National
securities exchanges including NYSE, Nasdaq and CBOE intend to follow suit and in
March, DTCC subsidiary National Securities Clearing Corporation announced that
it would increase clearing hours to support extended trading with
implementation targeted for the second quarter of 2026.

In
September, IG launched 24/5 trading on 110 of the most popular US stocks for UK
investors.

These
organisations are looking to tap into demand for longer trading hours from
investors in regions where traditional US market hours are not convenient as
well as from institutional investors who are not able to tap into the alternative
trading systems and retail brokerages that already offer round-the-clock
trading.

However,
there is recognition from industry groups of the need to allow market
participants to opt in or out of offering this extended window to their
clients, so that firms can invest in offering extended trading hours in a
manner commensurate with their business needs.

There
is also acknowledgment that 24-hour trading is not suitable for every type of trader.
For example, volumes will inevitably be lower in the middle of the night, which
can increase the risk of price slippage and widen spreads as well as making it
more difficult to fill orders.

Then
there is the matter of volatility. In a low trading volume environment there is
greater scope for exaggerated price swings – which can create opportunities to
pick up stocks below true market value but also make it difficult to assess that
value.

There
is also the human factor. Trading is already stressful and if markets never
close, the risk of burn-out will be that much higher. As my mother used to say,
you can’t put a price on your health.

Think
twice before taking credit

Andrew Bailey, Governor of the Bank of England

Over
recent months we have observed various instances of discord between the UK’s
most senior banker and the government’s chief finance minister, perhaps most
notably over the merits of a digital pound.

The
latest example relates to the equally contentious topic of private credit,
where high profile credit defaults in the US automotive sector have highlighted
concerns around high leverage, weak underwriting standards, opacity and complex
structures.

Andrew
Bailey, governor of the Bank of England, told a recent House of Lords committee
that the failure of First Brands and Tricolor could be indicative of a wider
malaise in the private credit market. He suggested that investors consider
whether these incidents are telling us something more fundamental about the
private credit sector.

The
Bank of England has said it will conduct a simulation to explore the
connections between the private credit market and other parts of the financial
system.

Meanwhile,
Rachel Reeves remains committed to making it easier for retail investors to get
access to long-term asset funds and by extension to asset classes such as
private credit.

The
UK chancellor has secured a commitment from 17 UK workplace pension providers
to invest £50 billion – a minimum of 10% of defined contribution default funds –
to private investments over the next five years, which includes private credit.
This aim of this initiative is to increase investment in private assets for
higher potential returns, with the hope of benefiting the UK economy and
pension holders.

Research
suggests growth in private investments will outpace that of public assets over
the coming years. However, that growth is likely to be uneven and some funds
feel that the market is unattractive at a time when interest rates are
relatively high.

Reeves
would love a rate cut ahead of next month’s budget – but that is yet another
area where government and central bank are not on the same page.
