It's too bad I didn't take screen shots for that post instead of links to StockCharts. CGNX was a pretty wild ride way back then. To get an idea of its volatility you could use PerfCharts: https://stockcharts.com/freecharts/perf.php?cgnx
Set the X-axis to 752 days and slide it across so that the start date is January 2nd, 2001. That period would approximate what we were looking at at that time. CGNX was and might still be a pretty good stock to AIM. A dear friend told me about CGNX back in the '90s and I bought and AIM'd it for probably 10 to 15 years, I'd guess.
Hope this helps, Tom PS: There are a lot of fun examples shown on that page. I believe I listed the B&H gain/loss vs the profits/loss from AIM trades shown on each.
