Why Hecla Mining Stock Surged in September

Hecla Mining (NYSE: HL) investors probably felt that they hit something of a mother lode in September. On the back of several factors, the company -- which primarily concentrates on silver, but also extracts desired goods from the Earth like gold and zinc -- saw its share price zoom more than 42% higher during the month.

One major catalyst for this double-digit rise was Hecla's ascension to a prominent stock index, which occurred on Sept. 5 and took effect on Sept. 22. In the quarterly readjustment of its indexes, S Dow Jones Indices saw fit to include the mining company on its S SmallCap 600 index.
