I'm sure some penny stocks have had multiple 1000% gains in a single day (SPEA went from about .50 cents to 12 dollars back in December "04). Disregarding those B.S. stocks though, I remember stocks like Books-A-Million going from like 8 bucks to 80 in one day (I'm 99% sure it was the day after Thanksgiving in 1998). I think it closed in the $40's, but it was a massive one day move. There were many small internet and biotech companies that went up a few hundred percent back in the day (late 90's). Most recently though, Velocity Express (VEXP) went from like 4 dollars to 21 dollars and closed around $14 (That was back in April of this year).
======= Akatrader Accelera.com made the Wall Street Journal in late 1990's, pennies to about $170 did much, much better than QCOM that year QCOM did about 2000% Numbers /names are approximate.
As far as non-penny stocks, I remember the day in 1998 when EBAY opened about $90 higher after good earnings. My father sold his 500 share position the day before because he didn't want to hold into earnings lol.
the biggest move i remember was broadcast.com i think it was bsct. it went up something like 90 in one day and came most of the way back.
The biggest I remember was some "china" internet stock. It went from 2 to 80 and back to 2 by the end of the day. This was in late 90's. John
