it's going to burst we all know that, its just a case of when. That's what we don't know.
if you keep pound averaging in you will be a tad bruised but totally fine.
Can you define a burst or what you believe may happen to the Tech sector

Just Googled and found this which suggests there are definitions for different drops in values -
Key Percentage Drop Benchmarks
While there is no single, rigid mathematical law for every market, financial markets use distinct definitions for drops:
• Dip / Pullback: A minor, short-term drop of a few percentage points.
• Correction: A drop of 10% or more (often up to 20%) from a recent high, happening over weeks or months.
• Crash: A rapid, severe drop—frequently 10% in a single day or 20% or more over a compressed timeframe.
• Bear Market: A sustained drop of 20% or more that generally lasts for several months or years.
Built-in Circuit Breakers
Major exchanges like the New York Stock Exchange use official percentage-drop thresholds (known as circuit breakers) to temporarily halt trading and stop emotional panic-selling:
• Level 1: A 7% drop in the S&P 500 triggers a 15-minute halt.
• Level 2: A 13% drop triggers a 15-minute halt.
• Level 3: A 20% drop halts trading for the remainder of the day.
To be honest i'd accept a drop of 10% - 20% (and indeed one of my funds I did post about a couple of months ago saying it was down 20% on the 12 month high) based on the fact that it's performed so well, this one which i've flagged up many times before -
External Link/Members OnlyIt's currently around 10% down on the 12 month high and indeed dropped just over 2.5% yesterday but 2 or 3 months ago was about 20% down on the 12 month high.
Looking at the 3 year growth chart if you'd have invested then you would be looking at a 250% increase with £1000 now worth £3500, in 3 years

If you'd have invested 5 years ago then the increase would have been 224% with £1000 now worth £3224 however at the low point the £1000 would have only been worth £716.98 so just over a 28% drop about 15 month in.
I'm not sure that the drop was classed as a crash as it happened over 12 months but it was certainly a severe correction (due I recall to interest rate rises stifling investment which we may well see again soon)
However I keep coming back to the fact that if i'd have invested £1000 in this fund 3 years ago and it halves in value when the markets open on Monday then it's still been a much better investment than £1000 invested in something viewed as safe returning 5% or even 10% or 20% a year
Just looking and if it fell by 2/3 then £1000 would still be worth £1166 so basically as good as that safe 5% stock which with 5% reinvested would still be worth slightly less at £1157
