My Shares and Shares ISA and Self-Invested Private Pension (SIPP) portfolios have began 2026 strongly. Some holdings are up by double digits, which is a pleasing shock.
Let’s take a better take a look at what’s occurring, and why one FTSE 100 inventory has began to make me uneasy.
Huge portfolio strikes
One robust inventory market commerce in the beginning of 2026 has been synthetic intelligence (AI). Rising AI-led demand is making a scarcity in reminiscence chips, pushing up costs.
I don’t personal any of those reminiscence chip shares, however my SIPP holding in main chipmaker Taiwan Semiconductor Manufacturing Firm has risen 8.7%.
In the meantime, my largest holding, MercadoLibre, has jumped 8.2%, largely off the again of Venezuela developments. It operates Latin America’s largest e-commerce market, and will now theoretically re-enter Venezuela (if the federal government embraces capitalism).
Even one in all my worst-ever inventory picks — mRNA vaccine maker Moderna — has joined the occasion. It’s up 15% to this point this yr (although it’s nonetheless too deeply within the pink for me).
Up 11%, BlackRock World Mining Belief continues to profit from rocketing gold and copper costs, constructing on its 73% surge final yr.
A more recent place — premium sportswear model On Holding — has elevated 9%.
Booming defence shares
One other development my portfolio’s benefitting from is a pointy rise in defence shares. This has been sparked by occasions in Venezuela and elsewhere, with President Trump now calling for US army spending to rise massively to $1.5trn in 2027.
As such, BAE Techniques and Rolls-Royce are up 19.7% and 10.3% respectively, yr thus far. BAE sources almost half its income from the US.
My third-largest holding, Axon Enterprise, has additionally benefitted, rising nearly 8% because it has some defence-related income.
A smaller holding — electrical plane producer Joby Aviation — might additionally profit from greater army spending. It has a deal to produce the US Division of Protection with plane. As such, its inventory has risen 15.5% in 2026.
I’m getting anxious
Whereas I’m proud of this begin, I’m clearly not counting my chickens after only one week. AI and defence shares might shortly pull again, and never all my shares are up (Roblox is down 10% and in freefall).
One holding from the FTSE 100 I’ve been worrying about is Coca-Cola HBC (LSE:CCH). The corporate makes and distributes Coca-Cola manufacturers throughout a number of European and African international locations, from “the West Coast of Eire to the tropics of Nigeria“.
The inventory has jumped 42% prior to now 12 months, pushed by strong operational efficiency.
So what’s my concern? Nicely, a lot of the firm’s income comes from tender drinks, and I worry gross sales of those might more and more be impacted by GLP-1 weight-loss medicine.
A number of medical research present these remedies can cut back candy cravings, which might theoretically embody sugary drinks (and presumably even their style, making them seem extra metallic).
As day by day Wegovy capsules turn out to be cheaper and accessible to numerous thousands and thousands extra folks over the subsequent decade, together with in rising markets, I fear this might harm gross sales progress.
Admittedly, Coca-Cola HBC additionally sells water and low, and doesn’t have a big snacks enterprise. The inventory’s cheap. So I don’t see any quick hazard.
Nonetheless, I worry it might ultimately undergo an analogous destiny to Diageo. As such, I’ll be retaining Coca-Cola HBC on a decent leash, whereas exploring different FTSE 100 alternatives.
