Thank you for your data mining. That pattern jibes with what I've seen in the gold part of the stock market: when gold's well down the bull track, the major producers go up, the juniors go up a lot, and the few exploration-level penny stocks that capture the punters' excitement explode.
Same on the downside, too. '11-'12 saw the majors getting whacked, the juniors getting whomped, and all-out carnage in the exploration-penny subsector.
I'm not kidding about the last. The pennies were hit so hard, the Venture Stock Exchange had to officially suspend a rule that prohibits secondary offerings by its listees whose stock price is below five cents. Yes, five cents.
Had the Venture board not done so, a lot of viable exploration micros would have had to hire bankruptcy lawyers. I'm quite serious about this.
