I know what you mean about the mistakes, I bought in FAS at $8 mid-February thinking I nailed the bottom. The Dow was about 7,800 at the time. First time buying on margin and within a week it was under $5 and I had to cover 90% (Scottrade rule)...luckily I had most of the money to cover but I sold enough shares at a loss to bring my average up to $9.60. I held FAS down to the $2.32 low on March 6 until I finally sold for a small loss around $9 mid-April.
...Anyways, this stock caught my eye today surfing around iHub: ACLS. I got in at .46 today and it closed at .48....in the after hours 24,000 shares were traded between .49 (a.h. low) and .50 (a.h. high) and the chart looks nice:
