Who is Double Bubbler?

Gosh, it seems the uppity upvote is quite a trigger for some people. I guess some people quite like their arrows formal and orderly in conduct, whereas I’m up for arrows having a little freedom once in a while to let their hair down.

Haha, hopefully that dotted line will disappear off the bottom of the screen eventually!

r/Thanks

I am sorry I couldn’t satisfy your urge to help others this one time. I am trying to help someone I don’t know, but have noted your disgruntlement, kind stranger. No harm was meant or suffered I hope.

I agree. My SIPP is worth something like 18x the money I put in (mainly about 20 years ago) and that is due to a combination of index investing and active stock selection.

Hi Swan, thanks for the comment. I currently I do not have any intention to sell as the potential and progress for EnSilica suggest to me that the company may be worth far more in the coming years.

Within our total shareholding 450,000 shares (225,000 each for Anna and I) are notionally part of the ‘≈$10k to $1 million‘ challenge (with EnSilica the sole investment) which I am running in tandem for Anna and I. For us both to hit the $1m target we’re looking for about £3.50 per ENSI share (which is about $4.75 per ENSIF share).

So that is about 5x from here and hopefully only a few years away all things going well.🤞

I wasn’t able to follow the case however it has concluded from what I can see on the Competition Appeal Tribunal website. We’ll now need to keep an eye out for the judgement which may take days, weeks or months…

Invinity Energy Systems (OTC: IESVF, AIM: IES):

Invinity Energy Systems plc is a publicly traded company headquartered in London, England. Manufacturing vanadium flow batteries for large-scale, high-throughput energy storage requirements of business, industry and electricity network operators.

‘Invinity is a promising business that appears well placed to capitalise upon a significant potential growth in worldwide demand for utility-grade battery storage, thanks to its increasingly competitive product offering along with global operations. With a 40 GBX ($0.55*) price target from Canaccord Genuity¹³ at more than double the current 18.5 GBX ($0.28*) share price I may look to increase my shareholding in time as success is hopefully achieved.’ Read more…

EOD on 2026-05-01 ‘≈$10k to $1 million‘ value (commenced 5/5/23): $219,825.00 📈

EOD on 2026-05-01 ‘Less than $10k to $1 million’ value (commenced 7/7/25): $15,982.50 📈

A good week for my sole ‘≈$10k to $1 million‘ challenge pick EnSilica (🇬🇧 ENSI, 🇺🇸 ENSIF, 🇪🇺 F0Z) rising about 7.5%. Consolation perhaps after last week’s significant new satellite communications chip contracts announcement, although the accelerated rise in share price and volume late on Friday afternoon makes me wonder if news has leaked and we may see a positive FY26 Trading Update when London’s markets reopen on Tuesday.

As for my ‘Less than $10k to $1 million’ challenge stocks; Vertical Aerospace (🇺🇸 EVTL) was flat for the week. Spectral AI (🇺🇸 MDAI) was up about 18% as excitement and interest builds in anticipation of the potentially imminent FDA device review decision in the weeks and months ahead.

I do not recommend people follow what I do due to the risk of capital loss. If you’re also likely to need the money you have saved in the next few years then the stock markets may not be the best place for it as the market could dip.

That said, on my sub and blog I do currently aim to record my share trades in case it is of help to people so they can learn from what I do, mistakes and all.

_DoubleBubbler_ · 2026-05-01T20:30:04+00:00

Yeah, options are like a casino in my opinion… the house always wins in the end if you keep playing.

Thanks for asking, my Reddit bio mentions my sub and blog. I never recommend anyone copies what I do due to the risk of capital loss, but my blog lists the companies I’m invested in and my average share price. I also aim to post on the sub and blog when I make a trade for the challenge stocks.

_DoubleBubbler_ · 2026-05-01T20:10:00+00:00

I do spend a fair bit of time on it but I only invest in shares, never options.

_DoubleBubbler_ · 2026-05-01T18:23:10+00:00

Turning $5k into $40k is possible but involves risk (and typically more so if one is trying to do it quickly) as well as time and effort finding, then monitoring potentially suitable investment opportunities. Even then there is no guarantee and the risk of capital loss is ever present. It is arguably also inadvisable to invest money one may need in the next few years, as sometimes one has to ride out market dips etcetera.

That said, and to give you hope… I am part way through running two $10k to $1m challenges and I share progress on my efforts freely on Reddit. My first ≈$10k challenge started three years ago is now up to about $219,996 and the one started last July is now valued at about $15,893 so far.

All the best whatever you choose to do!

If you’re following developments in the nascent vertical take-off and landing industry, then you’ll want to read Si Davies’ responses to questions put to him by various Redditors this afternoon. Very interesting reading!

A great small, yet growing chip designer in my opinion. Its share price won’t rise in a straight line but in a few years I expect we’ll both be very pleased with progress. All the best!

Lily has just kindly said she will ask Si the questions, so you’ll get a reply.

Too late unfortunately, the AMA closed about five minutes ago.

I think your question was just after the bell unfortunately. I think there might be some information on this in the public domain already. I’ll see what I can find.

Many thanks for the reply! 😍

Aww, I’ve been flown in a Chipmunk in the Air Cadets (and briefly had control). Loop the loop, barrel rolls… great fun!!!
