Wow, what a week 😁 … it all happens at once sometimes, and what a great week it has been. With stock markets also benefiting from an improving situation in the Middle East, with the temporary ceasefire and Iran currently allowing transit through the Straight of Hormuz.
My sole ‘≈$10k to $1 million‘ challenge pick EnSilica (🇬🇧 ENSI, 🇺🇸 ENSIF) had a great week following cross-listing on the US’ OTC Markets. Setting a new 52 week high of 70p / $0.95 and finishing the week up 38% at 68p / $0.92. With a forward price to sales (PS) ratio below 3 based on management guidance for the financial year ending next month, in my opinion there remains notable potential for near term and long term share price growth for this promising semiconductor firm (with end users such as AST SpaceMobile) given its forward PS ratio below 3. This compares very favourably with a ten year average PS of 4.5 for the British and 6.4 for the US semiconductor industries according to Simply Wall St data. Local firm Filtronic (FTC) a supplier to SpaceX is trading with a ratio of over 8, Nvidia (NVDA) over 13, so EnSilica below 3 is still in bargain territory in my opinion.
It will take weeks and months for broad North American access to ENSIF on the OTC Markets however the prospect of increasing access to the deep and wide pool of North American investor capital is a tantalising prospect. With high insider ownership, fresh capital from the recently oversubscribed fundraising, and the prospect of potential lifetime contract orders for over a hundred million in the satellite user terminal market place, where EnSilica like Satixfy who were acquired by MDA Space for 13x revenue, is developing the full suite of terminal chips thanks in part to grant funding from the British and European space agencies. All in all the future looks very promising and I maintain my hope that EnSilica will in the years ahead allow me to complete my ‘≈$10k to $1 million‘ challenge!
In my ‘Less than $10k to $1 million’ challenge Vertical Aerospace (🇺🇸 EVTL) had a humdinger of a week, thanks to its notable achievement of completing full flight transition with its prototype aircraft. A first for British and European based aviation, and given the apparent advantages of its anticipated Valo production aircraft we may have a future market leader in this promising firm. With EVTL rising 32% for the week, I finished the week within a hair’s breadth of doubling my starting challenge capital. In fact for a time on Thursday my initial $9,992.07 capital from last July was worth over $20,000 and well ahead of my goal of doubling my capital roughly every twelve months.
Given Vertical is seemingly well funded after its recent $850m fundraising announcement, while also making material aircraft testing and development progress, I expect over the next year or so to see a share price (currently $2.99) into double figures in my opinion. Given Vertical’s market capitalisation is about $300m compared to $9b for the only other eVTOL firm to successfully transition so far, Joby Aviation, I can also see potential for EVTL to double multiple times over the coming years all things going well. To the skies as Vertical Aeroverts say!!!
My other ‘Less than $10k to $1 million’ challenge stock, Spectral AI (🇺🇸 MDAI) finished up over 9% for week as interest seemingly grows in advance of its pivotal FDA device review decision, which is currently anticipated in the next few months. The share price (currently $1.89) rose to over $3 last year following its FDA submission so I would hope to see well over $3 again should the FDA approve Spectral’s novel AI enabled automated wound assessment device. With the full commercial potential still not visible, should we also see evidence of substantial potential as the year progresses then we may even see the share price exceed Zack’s valuation of $5 at some point in 2026.
All in all, weeks don’t come much better than this. What’s more, is that in all three of my challenge stocks there appears to be plenty of room for outsized growth ahead in my opinion. I look forward to the coming weeks and months with excitement.
May fortune favour the brave!
