BTH - You confuse a short, temporary, directional correlation with having a similar causal source of origin. The "quant" is your causal connection. The temporary similar tracking is unrelated and rather dissimilar when you look at it carefully. Concluding that they arise from any similar source is beyond speculation.
EXEL and ARIADs movement may track temporarily in a general direction but that doesn't establish any kind of relationship and certainly nothing to infer some big bogeyman "quant" at work.
This beautiful pig is just doing a few barrel rolls in the blue sky to entertain us before ASH.
