Yes you read that right. The plural of supernova is supernovae. I am obsessive about grammar. By the way, the plural of index is indices, not indexes. Anyway, supernovae are stocks that are up an insane amount, over 100% in a couple days; Tim Sykes originated the term. The supernova du jour is GGC, which I am now looking to short aggressively on the right price action (what do I mean by the right price action? Buy Sykes’ excellent DVD

I am a happy user of Stockfetcher.com. Here is the code I use to scan for supernovae.

show stocks where close gained more than 99 percent over the last 5 days
and price is between .25 and 15
average day range is above 8
and volume is greater than 500000

set{ DayChg1 , close – close 5 days ago }
set{ DayChg2 , DayChg1 / close 5 days ago }
Set{ 5DayPctGain, DayChg2 * 100}
add column 5DayPctGain
and sort column 5 descending
Set{5DaysAgoPrice, close 5 days ago}
and add column 5DaysAgoPrice

Looking for my watchlist? This is it. GGC is the stock I’ll be watching tomorrow. WUHN is also almost a supernova but I couldn’t find shares to short. AIG may be interesting, along with other finance plays, but I don’t like trading finance stocks. CMLS also on watch, more likely a good buy tomorrow than a short. I probably won’t play it.
