"It only take one bad apple to spoil the lot and it has."

"...and it has" is merely an opinion, though it may have some support from the market. It is not fact, right?

"What’s your explanation behind the recent drop in share price?"

I can't claim to know, but I suspect the price got a bit ahead of itself. And, as you suggest, maybe some sellers were trying to capture gains ahead of what they may fear from the summer doldrums.

I am comfortable for having purchased shares at or near the low each day this week. I'll continue this until the price turns up convincingly, though I feel the worst may be over for now.
